Recently, several articles have reflected on the existence of microorganisms in supporting the life and health of living creatures as the beginning of the emergence of microbiology literacy. In the curriculum, understanding the activity of microorganisms has been studied from pre-school, elementary school, and middle school to college. The presence of microorganisms is often associated as a cause of disease. As a result, most students know the negative impact of microorganisms but have not discovered the fundamental role of microorganisms in their lives. Special attention needs to be given as a form of effort to strengthen microbiology literacy. Several studies state that students have an important role in disseminating the concept of sterilization, maintaining a safe distance, and using masks as generally applicable protocols during the pandemic. Therefore, with the aim that microorganisms have an important role, both directly and indirectly and to curb negative perceptions of microorganisms, we propose microbiology competencies among biology education students, who are future teaching candidates. This article identifies the complex challenges of 21st-century microbiology learning and the OECD framework. This approach includes the use of pedagogical interventions with the main objectives: (i) knowledge (to teach fundamental microbiology knowledge, (ii) skills (to increase awareness in recognizing and solving real-life problems), and (iii) attitudes and values (to explain the contribution of microbiology in supporting life).

Have you ever deeply considered the intersections between research and education, particularly for second-level students? Traditionally, the convergence of these two realms is most often noted when considering the integration of research findings into educational practices or the involvement of, typically a small number, of students in research activities. While these practices have demonstrated efficacy, the fields of scientific research and education are evolving rapidly, necessitating a reevaluation of how we can optimize their convergence. In our discourse, we delve into these evolving trends, uncover the potential for greater integration, and, ultimately, enhance outcomes using the citizen science initiative Kefir4All as an illustrative example.

This paper presents two low-cost hands-on activities designed to enhance student understanding and address the pedagogical challenges faced by microbiology professors in teaching concepts related to cell structure and gene regulation. In the first activity, we used Shrinky Dinks and Jeopardy-style game questions to explore the differences between prokaryotic and eukaryotic cells. Students have to collect pieces and physically build their cell models. The second activity uses origami organelles sets from Edvotek to illustrate the regulation of gene expression in the "lac" and "trp" operons, incorporating mutation scenarios for analysis. The intended audience comprises undergraduate students in microbiology, including biology, pre-medical studies, and health profession majors. The activities were deployed in three microbiology lectures, and students were surveyed. Students' feedback highlights the efficacy of the hands-on approach and increased class participation, as two of the recurring words in the students' survey were "helpful" and "fun."

This study aims to develop a valid and reliable scale for determining the self-efficacy of teachers toward context-based science education. This study employed a survey design. The sample has formed 433 science teachers working in Kayseri province in the 2020-2021 spring semester. Firstly, an item pool of 85 items was developed by reviewing the literature. Secondly, a five-point Likert-type draft scale consisting of 67 items was developed. Required arrangements have been performed according to expert opinions to provide content validity. Explanatory and confirmatory factor analyses have been run to provide construct validity. As a result of explanatory factor analysis, a structure with four factors as "Learning/Teaching Process", "Self-efficacy Resources", "Academic Self-efficacy" and "Planning Instruction" consisting of 47 items has been reached. Factors have been confirmed by confirmatory factor analysis. Cronbach Alpha internal consistency coefficient has been calculated as 0.98. To provide criterion validity, the Pearson correlation coefficient has been found as 0.86 between the draft and criteria scales. Based on the findings, researchers have determined that the scale was valid and reliable, and they recommended that this scale should be used to determine self-efficacy beliefs towards context-based learning of science teachers.

In this randomized control study, we evaluated science teachers' pedagogical practices via classroom observations following ongoing, intensive, and structured instructional support sessions. These sessions included virtual professional development (VPD) and virtual mentoring and coaching (VMC) that accompanied a literacy-infused science curriculum. Using a low-inference observational instrument, we explored the direct impact of VPD and VMC on fifth-grade science teachers' observed time allocation in a randomized controlled trial (RCT) validation study. The observations were collected three times during science instruction from 121 teachers in 68 schools from 35 public school districts in the U.S. state of Texas, during the 2017-2018 school year. Preliminary findings revealed pedagogical differences in time allocation among teachers between treatment and control classrooms. We identified improved instructional practices within treatment classrooms, which suggests the intervention had a positive effect by enhancing the quality of pedagogy as well as the content-area instruction in science.

Development of scientific explanation abilities in students is an important aspect in science education. However, traditional learning methods such as textbooks and PowerPoint presentations are often less effective in improving skills due to lack of student interactivity and involvement in the learning process. This study aimed to analyze the effectiveness of using augmented reality media based on problem-solving frameworks to empower scientific explanation. The research design was used a Nonrandomized Control Group, Pretest-Posttest Design. The study used a quasi-experimental method with a factorial design of 2 x 2. The research sample was 72 students, one of senior high school in Indonesia. The sample was divided into two groups: the control group using two-dimensional learning media based on books, PowerPoints, and videos. The treatment group used augmented reality learning media based on problem-solving frameworks. The material used in the study is the human circulation system in biology subjects. The instrument used to obtain scientific explanation data is an essay test developed from scientific explanation indicators adapted from McKneill et al. Data analysis using ANCOVA (p=0.05%) with pre-test values as covariates. The results showed that augmented reality media based on problem-solving frameworks could empower and more significantly improve the ability of scientific explanation, this is evidenced by the average value of scientific explanation skills in the experimental class is higher than the control class.

This research aimed to determine students' opinions on technology-supported drama activities applied in teaching the subject of the central nervous system in the biology course. The research used a case study design, a qualitative research method. The study was conducted with 25 students studying biology at a state university. An appropriate sampling method was used to determine the study group. Within the scope of the research, a semi-structured interview form was used to determine students' opinions about technology-supported drama method applications. This form allowed students to express their experiences in depth. The research results indicated that the students had a generally positive perspective on the technology-supported drama method used in the biology course. Since technology-supported creative drama activities provide students with a learning environment that they enjoy, this method can be recommended to increase students' interest in lessons and ensure permanent learning of content.

Due to the difficulty of chemical compounds to visualize, augmented reality (AR) integrated with mobile learning has been developed as an alternative media for studying chemistry. This study aims to analyze the use of AR-integrated mobile learning in chemistry education from a bibliometric perspective in the last decade. A total of 225 articles were retrieved and analyzed from the Scopus database in the period from January 2012 to September 2022. The results of the analysis indicated that in the range of 2012-2022, the highest number of publications occurred in 2021, with the United States as the most productive country with a total of 54 publications, followed by China, Indonesia, and Japan. Wojciechowski, R., is the most frequently cited author, followed by Cai, S. "Augmented reality" is the keyword that appears most frequently in publications. This study presents useful findings that can serve as a guide for educators, scholars, policymakers, and educational designers for future research or reference in this area regarding current trends.

The main purpose of the research is to determine teachers' views on the use of digital games in science education. In accordance with this purpose, the research was carried out with the phenomenology method which one of the qualitative research methods, was conducted with eight volunteer science teachers working in different public schools within the 2022-2023 academic year. The participants of the study were selected via the criterion sampling method, which is one of the purposeful sampling methods. A semi-structured interview form was used as a data collection tool in the research. The data collected taking this interview form into consideration was analyzed using the content analysis method. Through the interviews was concluded that digital games are a tool that helps students focus on their attention and learn permanently. Besides, teachers stated that digital games measure science achievements at the sub-cognitive level (knowledge and comprehension) of Bloom's taxonomy. Based on this, digital games ought to be designed to measure the meta-cognitive level of Bloom's taxonomy.

In recent years, there has been a growing concern in science education on the enhancement of preschoolers' knowledge and motivation for concepts by implementing efficient teaching methods. This study explored the development and effectiveness of the E-sky Module in increasing the development of preschoolers in Project-based Learning (PBL) activities conducted both within and outside of preschool. This study employed the Design and Development Research (DDR) approach, incorporating many research methods. During the qualitative interviews conducted in the needs analysis phase, three different themes related to the difficulties encountered by teachers when conducting early science projects were meticulously recorded and analysed. Based on a quantitative analysis completed by three experts in the field, this E-sky Module has been determined to have a substantial level of validity and a satisfactory level of reliability. This is evidenced by a Cronbach's alpha coefficient of (p < 0.82) observed. Moreover, throughout the evaluation phase, four distinct themes were effectively reported, suggesting that this module significantly contributed to the comprehensive development of preschoolers. Hence, future studies should explore the potential of enhancing knowledge acquisition through promoting motivation and the emergence of conducive learning environments in the context of PBL.

This study examined the impact on the motivation of students toward learning physics upon applying the Nikola Tesla Center (NTC) learning system. The research was conducted using a quasi-experiment with a pretest-posttest non-equivalent control group design. The participants considered were a large group of 1371 students, from various grades and mixed genres, selected from the same district in Serbia. The instrument of this research was the students' motivation toward science learning (SMTSL), which has been adapted to measure the motivation of students and their learning strategies for physics. Statistical analysis included calculations of Cronbach alpha, chi-square, Kolmogorov-Smirnov (KS) test, independent Samples t-test and ANCOVA, and Pearson correlation test. The study found that using the NTC learning system had a positive effect on students' motivation to learn physics. The experimental group had significantly higher scores on various subscales of motivation such as self-efficacy, active learning strategy, physics learning value, performance goal, and learning environmental stimulation compared to the control group. The research results determined that the NTC learning system is an effective method for promoting motivation of students toward learning physics and it can be recommended for implementation in schools.

Despite achieving similar college degrees, students venture into different paths post-graduation. Having a career plan with career aspirations and future career perspectives is essential for an individual to have a more straightforward career path. This qualitative narrative inquiry research determined science education students' career aspirations and future career perspectives. Nineteen college science education students in a state university in Zambales, Philippines, were asked about their written narratives describing their career aspirations and future career perspectives. Data from the participants were subjected to thematic analysis following Braun and Clarke's (2006) framework. Findings showed that science education students' career aspirations were (a) to teach and inspire students, (b) to pursue advanced studies, (c) to take licensure examinations, (d) to work abroad, and (e) to shift career. Meanwhile, the science education students' perspectives toward their career after 10 years were (a) to become successful in the teaching field, (b) inspiring and teaching the students, (c) contented in the chosen profession, and (d) willing to embark on another journey. Based on the findings, researchers recommended the creation of career guidance and career management programs among graduating students to provide more apparent career aspirations and career perspectives among them as they become future professionals.

This paper describes and compares primary school students' perceptions of science learning skills in a teacher-centered approach (TCA) and in inquiry-based science fieldwork (IBSF). This comparison was prompted by primary school students' perceptions of science learning skills, which has recently gained momentum, and the Namibian primary schools' recent curriculum shift from TCA to IBSF. The study utilized quantitative cross-sectional data (n = 237) collected from two primary schools in the Oshana region of Namibia. The data were gathered via an online survey and were analyzed using descriptive statistics. The Mann-Whitney U test was used to compare the TCA and IBSF groups. The results revealed that the students had positive to fairly positive perceptions of science learning skills in IBSF and very negative to negative perceptions of science learning skills in TCA, with the difference between the two perceptions being statistically significant. This may indicate that Namibian primary school students find it hard to develop science learning skills under TCA. Therefore, the current study provided evidence for the need to focus more on supporting students' science learning skills, particularly problem-solving, communication and teamwork skills. This implies that the IBSF teaching approach, which allows students to become aware of the importance of science learning skills, must be adopted in Namibian primary schools. The paper also discusses the benefits of IBSF of science learning skills in students.

This study aimed to investigate research trends related to socio-scientific issues (SSI). The SSI articles analysed were from highest-rating five science education journals with the highest impact ratings, published between 2011 and 2022, including "Science Education" [SE], "Journal of Research in Science Teaching" [JRST], "Science and Education" [S&E], "International Journal of Science Education" [IJSE], and "Research in Science Education" [RSE]. A total of 87 selected relevant SSI articles were analysed to determine research types, research topics, research sample groups, research sites, and authors with the most citations. According to the research findings, IJSE articles are the most widely published articles compared to other articles of similar journals. It is revealed that the most discussed issues in those articles of IJSE are argumentation and decision-making, followed by the nature of science. Pupils in middle and high schools constitute the largest sample groups. The continent that has been widely selected as research sites is European continent. Meanwhile, the country with the most research sites is the United States. The data collection tool most frequently used in the research is interview. S&E's "Nature of Science," "Scientific Inquiry," and "Socio-Scientific Issues Arising from Genetics: A Pathway to Developing a Scientifically Literate Citizenry" articles are the most cited articles. Challenges such as addressing efficacy, emotion, and attitude remain noticeably unexplored in SSI studies. Furthermore, exploratory studies on SSI for early childhood education.

This study made a preliminary attempt to conduct a needs assessment of teachers' utilization of the SSI-based approach in teaching Science by exploring Filipino teachers' awareness, perceived need, readiness, and willingness. It also aimed to determine which among the demographic profiles of the teachers had significant differences in their perceived need and readiness. A needs assessment using a quantitative survey research design was used in this study. The data-gathering procedure was done using a validated online survey questionnaire with a Cronbach alpha of 0.89. A total of 124 science teachers participated in this study throughout the two-week implementation. Descriptive and inferential statistics were used to analyze the data gathered from this study. Results revealed that more than fifty percent of the teachers were highly aware of the SSI-based approach and perceived the need for its implementation in science classes. Teachers were also willing to participate in an SSI training program to learn more about it and develop their own SSI-related materials. Furthermore, gender and specialization significantly differed in teachers' perceived needs, while specialization significantly differed in readiness. Results obtained from this study can be used as a basis for exploring teachers' perceptions and views of implementing the SSI-based approach.

Preservice teachers who are specialising in the teaching of the subject natural science at a primary school level, ought to demonstrate the ability to present lessons that provoke a joyful yet meaningful educational experience amongst learners. One such approach that was taken, was when natural science preservice teachers were tasked with developing educational science board games as a means to enrich their teaching practice during a recent school visitation opportunity. However, given this educational exercise, what remains a mystery from a teacher development perspective is whether this exercise provoked some form of 'pedagogical thinking' among preservice teachers? It is with this question in mind, that the study investigated whether the task of developing educational science board games sparked the ability of preservice teachers to demonstrate knowledge of pedagogical content. The study draws on a modified understanding of Shulman's pedagogical content knowledge model, which in the context of gamification requires one to effectively transmit 'subject knowledge' in an interactive manner through 'educational board game practices and engagement'. Using a focus group discussion and photo-voice methodology as data collection techniques, this qualitative study uncovered how preservice teachers demonstrated i) knowledge of the curriculum, ii) knowledge of instructional strategies, iii) knowledge of learner-thinking, and iv) knowledge of assessment. This study holds a series of implications for future research in the field of initial teacher development and STEM education. For example, it will be interesting to uncover how preservice teachers experience the use of educational board games in their teaching. In addition, it will also be interesting to discover how educational board games can be used in other STEM subjects such as mathematics, technology, and physical science. Ultimately, more research is also required on the learning benefits of educational board games from a learner's perspective.

Background: Preschool teachers play a key role in early scientific education, and their understanding and ability to communicate scientific concepts are crucial. Researchers have extensively studied their grasp of basic scientific concepts, but their understanding of important concepts related to buoyancy, such as floating and sinking, remains relatively underexplored at this level. Aim: This study sought to investigate Grade R teachers' understanding of buoyancy principles by focusing on the concepts of floating and sinking. Setting: The study was conducted in Maseru, Lesotho with four Grade R teachers in their schools. Methods: This study employed a qualitative research approach characterised by a case-study design within an interpretive paradigm. Thematic data analysis was used, drawing from semi-structured interviews with four purposefully selected Grade R teachers. Results: The study found that Grade R teachers have a partial grasp of floating and sinking concepts. While they can describe these principles at a basic level, their ability to explain the reasons behind objects floating or sinking is limited. Conclusion: The incomplete understanding of the floating and sinking concepts among Grade R teachers could negatively impact students' knowledge of science. Therefore, it is advisable to implement an in-service science content-focused programme to empower and equip teachers with the necessary knowledge and skills. Contribution: This study contributes to the limited literature on understanding basic scientific concepts such as floating and sinking in early childhood education. Neglecting these concepts may impede students' learning if not properly addressed.

This study aimed to develop and evaluate a web-based TPACK scaffolding for online learning to enhance the TPACK skills of preservice chemistry teachers. The preliminary study identified the lack of a clear perception of TPACK among preservice chemistry teachers. Therefore, we developed a web-based TPACK scaffolding tool consisting of five menus: Home, Instructions, Teaching Materials, TPACK Activity, and Evaluation. The tool provides scaffolding for preservice chemistry teachers to integrate TPACK into chemistry learning, such as a TPACK integrated syllabus, a TPACK integrated lesson plan, and a TPACK integration matrix in chemistry learning. We evaluated the readability and comprehensibility of the web-based TPACK scaffolding using the thinking aloud protocol (TAP) method. In addition, the participants provided suggestions for improving the website, such as adding an instruction button, grouping learning activities according to the sequence of scaffolding strategy steps, and grouping integrated TPACK lesson plans in chemistry learning according to grade levels in high school. The web-based TPACK scaffolding can support and guide preservice chemistry teachers in enhancing their TPACK skills. The tool can educate them about subject-specific pedagogy with TPACK integration and provide examples of TPACK activities that could be utilized in teaching and learning chemistry. The study's findings can enhance preservice teachers' TPACK skills and promote effective integration of technology in chemistry education.

The aim of this study is to reveal the content analysis and trends of studies on misconceptions in biology education. Within the scope of the research, articles containing misconceptions about biology were accessed from the Scopus database. "Biology and misconception" was searched in the title, abstract and keywords in the Scopus database on September 13, 2022. A total of 410 publications about misconceptions in biology education were found in the search. The years of accessed publications were determined between 1970 and 2022. A total of 410 publications were analyzed in the research, regardless of language. According to the data obtained, 53 countries and 143 journals published articles on misconceptions in biology. However, in order to obtain clearer data, 3 articles were determined as the minimum number of articles for a country, and 31 countries and 27 journals were considered in this research. According to this research, in terms of the number of documents, the USA is the most published country with 199 articles, and Turkey is the second most published country with 39 studies. It was also revealed that the most cited countries were the United States, Australia and the United Kingdom, respectively. "CBE Life Sciences Education" and "American Biology Teacher" journals were determined as the journals with the most publications on the subject. In addition, Journal of Research in Science Teaching, CBE Life Sciences Education, International Journal of Science Education, Journal of Biological Education, Evolution: Education and Outreach were identified as the most cited journals in the studies. The results of this study are thought to be important for the future development of studies on misconceptions in biology education. Regarding the results obtained from the research; Different indexes can be used in future studies, and other types of publications such as theses, conference proceedings or books can be used in analyses.

Multiple external representations (MERs) are useful for teaching complex content in science education. An open question is whether there is an especially effective way to sequence MERs. On the one hand, the so-called concreteness fading approach suggests starting instruction with more concrete representations and proceeding stepwise to more idealized representations. The effectiveness of this fading approach is, however, supported mainly by studies in mathematics education, while the results in physics are equivocal. On the other hand, presenting different representations simultaneously may support linking, that is, the comparison and contrast of representations, which may benefit learning. In an experimental classroom study (N = 187), we compared concreteness fading and simultaneous presentation of MERs for learning a challenging physics content in high school, namely, Faraday's law. We found no significant differences between conditions in posttest performance, and an equivalence test with bounds d = -0.5 to 0.5 showed that both approaches performed equally. The results align with previous findings questioning the superiority of concreteness fading over other ways of sequencing MERs. Therefore, facilitating students' understanding of a complex physics content may involve more than determining the optimal order of presenting MERs. We discuss limitations of the present study and implications for future research and practice.

The Framework for K-12 Science Education set an ambitious goal of broadening participation in science learning for all students. Meeting this vision will involve supporting teachers in making meaningful connections with the cultural and linguistic resources their students bring to school; in essence, developing pedagogies that frame these resources as assets important to learning. In this manuscript, we present a qualitative case study of one community of high school science teachers who participated in a year-long professional learning focused on formative assessment co-design related to natural selection. Findings show that the process of formative assessment co-design surfaced both deficit- and asset-based statements about students' contributions. Teachers were more likely to share deficit-based statements as compared to facilitators, whose statements were more asset-based. This was particularly true with reference to students' prior knowledge and linguistic resources. At the same time, our analysis suggests that teachers were more likely to share more asset-based framings of learners when practicing for and reflecting on enactment of formative assessment tasks. These findings suggest that supportive co-design environments can encourage teachers to take more asset-oriented views of learners. We discuss the implications of these findings for professional learning and science classroom practice.

This is a study intended to address white supremacy in science education. To accomplish this, we describe how one White intern, Boaz, learned to teach science in anti-racist ways. By detailing how whiteness mattered in his learning to teach, we demonstrate that whiteness is potentially constant in White peoples' learning to teach science in anti-racist ways. However, we conclude by suggesting that critical whiteness ambitious science teacher education, a merging of critical whiteness pedagogy with practice-based science teacher education provides a potential way to address the presence of whiteness in science teacher education.

A new teaching resource comprised of raw X-ray diffraction data sets from crystallography experiments has been compiled. The aim of this resource is to provide a tool with which to plug the teaching gap between crystals and chemical structures present at various levels of education, as well as providing examples for early stage researchers and institutions without the requisite instrumentation to use for training. The data sets mirror the contents of the highly successful CSD Teaching Subset and include examples that demonstrate the effects of wavelength, crystal quality, and collection temperature. As crystallography underpins our understanding of chemical structure, exposure to the technique will be beneficial to students in terms of providing understanding of where the structures in the CSD Teaching Subset originate as well as insights into many overlapping fields such as scattering theory and symmetry. The resource will be available through the CCDC Web site and will provide links to the software required for data processing and documentation describing its use. It is hoped that this resource will expand with contributions from users in terms of both data and teaching exercises.

Promotion of students' scientific literacy has long been and continues to be a central goal for reform efforts in science education. Although there is a great number of research conducted to evaluate student's scientific literacy, less is known about how we can improve students' scientific literacy through variety of scientific practices. In this study we aimed to refer to this shortcoming in the literature by examining the effect of argument driven inquiry (ADI) instructional model to promote 8th grade students' scientific literacy. A mixed method quasi experimental design was used in this study. Sixty-seven eighth grade students from the same public school attended the study. Two intact classes were randomly assigned either in structured inquiry (SI) or ADI groups. The data sources included a Scientific Literacy Assessment (SLA) and semi-structured interviews. The results indicated that students experiencing ADI instruction scored higher on the SLA-D test and personal epistemology dimension of SLA-MB test than students experiencing SI instruction. The results propose that engaging students in meaningful scientific practices may support their scientific literacy.

This study aims to explore the meanings communicated by young children with visual cultural semiotic resources available in the science classroom. It is a case study in an Early Childhood Education classroom of 23 children (3-4 years old) and their teacher, all engaged in a long-term science project about snails. We focus on the analysis of two series of drawings of snails made by children a month apart, examined through two complementary lenses: comparative content and social semiotics. The findings show that, during their first year of formal schooling, children acquired a range of semiotic resources to communicate to others, which are part of their classroom culture, rather than explicitly taught. Children used these resources to construct sophisticated meanings through their science drawings, highlighting what they considered important and accounting for different modalities and categories. These results point to the importance of supporting drawing tasks in early years, as well as providing opportunities for discussing and interpreting representations. A methodological contribution of this research regards the combination of two complementary foci in the analysis of children's drawings that allows for a nuanced examination of their learning and abilities for meaning making.

Previous studies have shown both benefits and challenges of group work and whole-class activities in educational settings. One overall finding in the existing literature is that it is challenging for teachers to facilitate whole-class conversations that realise the rich potential of student discussions and undertakings during group work. This article investigates how teachers can facilitate productive consolidating whole-class conversations building on students' group work experiences by enacting responsive teaching practices, implying foregrounding students' experiences and ideas, and pursuing the substance of the students' experiences and ideas in instructional work. Based on a sociocultural perspective, we analyse sequences of classroom interactions where students' experiences from their lifeworld are invoked in a) settings where student engage in small group activities and b) teacher facilitated whole-class conversations. The educational context is a science project about genetics involving lower secondary school students and their science teacher. Our analysis shows that in group work settings, students' everyday experiences are invoked but are seldom picked up on and pursued in group conversations as resources for engaging with science matters. In whole-class conversations facilitated by the teacher, especially in situations in which the teacher assumed a responsive teaching approach, students' everyday experiences were more often realised as resources for shared meaning making and engagement with scientific concepts and ideas. We discuss this study's implications for teachers designing productive learning activities that combine group work and whole-class activities.

This paper presents and discusses the inclusive inquiry-based alternate reality game (IB-ARGI) approach, a pedagogical gamified approach supporting inclusive contemporary educational contexts. The IB-ARGI approach comprises Inquiry-based Learning, Alternate Reality Games, Universal Design for Learning and Augmented Reality technology in order to shape an inclusive inquiry-based learning environment for all students. The aspects of the IB-ARGI approach are illustrated and discussed by focusing on an IB-ARGI implementation on the topic of Magnets and Magnetism for 65 preschool student teachers in the context of a laboratory course in Science. The study aims to explore preschool student teachers' perception of the IB-ARGI approach as learners and future teachers using a mixed method approach and assess the intervention's learning outcomes through pre- and post-tests. The results revealed fruitful insights into how the IB-ARGI approach motivated the student teachers to actively participate in the inquiry through an immersive experience involving multiple means of engagement, representation, and action and expression. Findings concerning the learning outcomes also indicated significant learning gains for the participants. Despite this work's suggestive and exploratory nature, the study offers new perspectives and findings to the literature regarding the formation of more inclusive inquiry practices. Additionally, it contributes to opening a route in the current literature concerning the formation of more inclusive approaches and practices in science education.

Students in a typical instrumental analysis course may learn more than 30 analytical techniques. There are more than 150 components associated with the instrumentation that they learn. To help students organize this large amount of information, we classified these components into four categories: sources, samples, discriminators, and detectors. In this work, color-coded pictograms are used to help students identify components associated with a particular instrumental technique. For example, a UV-visible spectrophotometer can be depicted by using four color-coded pictograms. Pictograms were created for instrumentation on each of the following topics: spectroscopy, electrochemistry, chromatography, elemental analysis, surface analysis, and thermal analysis. Methods to incorporate these pictograms into the instrumental analysis course and assess their effectiveness are provided.

Background: Research on cognitive effects of educational games in general shows promising results. However, there are large variations in learning outcomes between individual educational games. Research on the design process and different design elements of educational games has led to some interesting directions, but some design aspects remain unclear. Objectives: We examined how an educational game designed on the basis of intrinsic integration theory, based on a strong alignment between game and learning goals, supports the learning of Newtonian mechanics. Methods: This study applied a mixed-methods approach (N = 223). A pre- and post-test design was used to examine possible learning and transfer effects fostered by playing the educational game, Newton's Race. To examine how players played the game, log data for each player were digitally recorded during gameplay. Results and Conclusions: Our findings demonstrated a significant positive learning effect of Newton's Race (p = 0.003, d = 0.201). This can be explained through the acquired log data. Log data show that players' gameplay mostly matched expected learning during the game, with physically correct game settings occurring more and more as gameplay progressed. The ability to transfer learned knowledge to other situations was shown to be limited to situations closely resembling the game environment. Implications: Similarly, designed intrinsically integrated games on different (physics) subjects could also foster learning in a relative short time. To foster transfer to other situations we propose embedding the game within other instructional activities.

Enabling students to learn about science is essential for science education. Students are expected to not only gain scientific knowledge but also need to develop a deep understanding of science. One approach to equipping students with a sense of science is to present science as a living collective human enterprise. As essential educational resources, science textbooks are powerful supportive tools for helping students be aware of the tentative, historical, and humanistic features of science. This study aims to develop and validate a comprehensive analytical framework for examining how a science textbook enables students to understand science and scientists through scientists' portrayals. The final analytical framework comprises five themes and 13 dimensions concerning scientists and their work, including the textbook's representation method (i.e., format and role of representation), scientists' background (i.e., personal and social background), scientists' work-related features (i.e., motivation for doing research, research methods, and way of working), scientists' achievements (i.e., type, evaluation, and influence), and educational values of scientists and their work (i.e., scientific thinking, scientific attitudes, and social responsibility). The analysis results of an American high school science textbook indicate that the framework developed is feasible to cover all the desired scientist-related elements and evaluate the extent of scientists' portrayals presented in the textbooks. In addition, the results also revealed that this textbook is inadequate in providing students with a comprehensive understanding of science and scientists via its portrayals of scientists.

This article presents a comprehensive exploration of ipsative and sociomaterial assessment methodologies, dissecting their theoretical frameworks, practical implementations, and the resultant effects on educational paradigms. The purpose of this article is to introduce a combined ipsative-sociomaterial assessment framework for science education at universities. The potential of this novel assessment methodology to influence student engagement, knowledge retention and educator practices is explored. Through a detailed analysis of existing literature and case studies, the article seeks to understand how these methods can transform science education. Four key themes are emerging: science education naturally leads to sociomaterial assessment, enhancing learning through ipsative feedback, measuring personal learning gain and reconciling ipsative with conventional assessment practices in the era of generative AI. Practical aspects of implementation in different online learning environments are discussed as well as institutional challenges that must be overcome. It is concluded that ipsative-sociomaterial assessment represents a transformative, yet natural approach in science higher education with the promise to enhance the educational experience and to provide a richer, more accurate reflection of student learning and achievement.

The greenhouse effect is a complex scientific phenomenon that plays a crucial role in understanding climate change. Grasping students' understanding of this phenomenon on the content-specific level but also how students' conceptions are organized is vital for effective climate change education. This study addresses both levels and delves into the relationship between students' frameworks and knowledge pieces of the greenhouse effect through the analysis of multiple-choice questions, employing Bayesian correlations and multiple logistic regression. We thereby focus on specific types of conceptualizations of the greenhouse effect that have been identified in previous research and furthermore investigate the coherency of them. To do so, we analyzed answers of N = 604 grade 11 students in Austria and Germany and interpreted them from different theoretical perspectives. The findings showed that students hold various ideas about the greenhouse effect that are only seldom coherent, in particular when it comes to adequate ideas about the greenhouse effect. However, especially for a reflection-based framework of the greenhouse effect, our results demonstrate that students' conceptions show some form of coherency. We argue that our results can inform the development of effective teaching strategies that address students' existing knowledge and alternative conceptions. In terms of practical implications, the findings suggest that teaching strategies should provide opportunities for students to integrate their knowledge pieces into a more coherent understanding of the greenhouse effect. The study highlights the need for further investigation into the relationship between knowledge pieces and frameworks not only for the greenhouse effect, but for science education in general.

This paper presents a literature review of science teaching approaches that seek to support equity in science classrooms, focusing on marginalization based on (i) race/ethnicity, (ii) social class/socioeconomic background, and (iii) religion. Considered were approaches that science teachers can use in science classes in secondary schools. They were analyzed and discussed against the backdrop of critical pedagogy by Paulo Freire and the educational theory by Hannah Arendt, which constitutes a novelty in science education research. The review used meta interpretation combined with systematic searches in the ERIC database. It is, thus, limited to works published in English. A total of 930 articles (2013-2021) were identified out of which 64 were fully analyzed. The analysis shows that most approaches strive to provide more equal access to the existing science knowledge and structures of the community. This corresponds to the introduction to the "old world" in a conservative interpretation of Arendt's term. I argue that in addition, it is necessary to employ a more radical interpretation of the "old world" as fundamentally plural which is done in translanguaging and grappling with racism. Further, the transformative nature of science education needs to be strengthened in terms of Freire's critical pedagogy and Arendt's concept of natality. This means allowing students to become aware of oppressive structures to induce change. Only youth participatory science, youth participatory action research, and grappling with racism explicitly aim for this. This shows that nuanced perspectives on equity in science education are needed.

An essential aspect of scientific practice involves grappling with the generation of predictions, representations, interpretations, investigations, and communications related to scientific phenomena, all of which are inherently permeated with uncertainty. Transferring this practice from expert settings to the classroom is invaluable yet challenging. Teachers often perceive struggles as incidental, negative, and uncomfortable, assuming they stem from students' deficiencies in knowledge or understanding, which they feel compelled to promptly address to progress. While some empirical research has explored the role of scientific uncertainties in driving productive student struggle, few studies have explicitly examined or provided a framework to unpack scientific uncertainty as it manifests in the classroom, including the sources that lead to student struggle and how teachers can manage it effectively. In this position paper, we elucidate the importance of incorporating scientific uncertainties as pedagogical resources to foster student struggles through uncertainty from three perspectives: scientific literacy, student agency, and coherent trajectories of sensemaking. To develop a theoretical framework, we consider scientific uncertainty as a resource for productive struggle in the sensemaking process. We delve into two types (e.g., conceptual, epistemic), four sources (e.g., insufficiency, ambiguity, incoherence, conflict), and three desirability considerations (e.g., relevance, timing, complexity) of scientific uncertainties in student struggles to provide a theoretical foundation for understanding what students struggle with, why they struggle, and how scientific uncertainties can be effectively managed by teachers. With this framework, researchers and teachers can examine the (mis)alignments between uncertainty-in-design, uncertainty-in-practice, and uncertainty-in-reflection.

Plastination, a permanent preservation method for human tissues and organs, is increasingly being used in anatomy education. However, there is a paucity of systematic reviews and meta-analyses summarizing the educational efficacy of plastinated specimens. This meta-analysis compared the assessment scores of students exposed to plastinated specimens against those exposed to other common instructional methods. A systematic search was conducted through four databases, from 2000 to July 2022. Titles and abstracts of the retrieved records were screened according to predetermined eligibility criteria. Of the 159 records screened, 18 were subjected to full-text review. Among the 18 studies, five articles reported post-intervention test scores for intervention (plastinated) and control (other modalities) groups. Studies were subjected to GRADE quality assessment, and four studies with moderate to high ratings were included for meta-analysis. Students' perceptions (n = 15 studies) were qualitatively analyzed using an inductive narrative analysis. No significant effect was detected between the intervention (n = 417) and control groups (n = 422) (standardized mean difference = 0.08; 95% CI [-0.36, 0.52]; p = 0.73). Four themes emerged from students' perceptions: ease of use, motivation to study, spatial understanding, and learning preference. Overall, student performance outcomes comparing the use of plastinated specimens versus other instructional modalities are very limited. This meta-analysis suggests that knowledge gained from plastinated specimens is comparable to learning achieved through other modalities; though this outcome should be interpreted with caution as there is currently insufficient evidence for definitive conclusions.

Whilst teaching about the nature of science (NOS) is a significant goal of science education, there remains debate about specifying the NOS and appropriate pedagogies and approaches to researching the NOS. A neglected, but conceptually and practically significant, problem is the proliferation of NOS-related learning goals such as NOS beliefs, views, understandings and knowledge. In this theoretical paper, we argue that such goals are often poorly defined, and different goals cohere with different pedagogical and research strategies. We propose a novel three-part taxonomy of NOS learning goals (as NOS beliefs, knowledge and understandings) and contend that different approaches are appropriate for teaching and assessing NOS beliefs, views and knowledge. An NOS belief refers to a positive attitudinal stance towards some proposition that lacks justificatory support or cannot easily be judged true or false. NOS knowledge indicates justified true beliefs related to the NOS. NOS understanding denotes a grasping of how a collection of NOS knowledge is related. The goals vary by the extent to which they can be judged true or false and the degree of justification they require. For NOS beliefs, a range of stances is acceptable; NOS knowledge must be a true and justified belief; in the case of NOS understanding, teaching and assessment should focus on the appreciation of relationships between justified true beliefs. The novel taxonomy brings needed clarity to a confused aspect of NOS research and may lead to the development of NOS pedagogies and assessment tools more precisely targeted to well-defined learning goals.

Nature of science (NOS) has been a target of interest for decades. The main goal of this study is to explore the impact of the science, technology, society, environment (STSE) approach on students' understanding of NOS, taking "Galileo's study of free-fall motion" as an example. Participants in this study were 350 students of grade 10 from a public high school in China. The "Student Science Understanding and Scientific Inquiry" (SUSSI) instrument was used in the intervention and control groups to explore the impact on students' NOS. The intervention group (N = 210) participated in the STSE class, whereas traditional instruction was applied to the control group (N = 140). Results revealed that there was a significant difference between the two groups, and the learners in the intervention group understood NOS better than the control group. STSE approach is an effective way to enhance students' understanding of NOS. Despite the fact that the implementation is challenging for teachers, it appears that the STSE approach has positive effects on students' understanding of NOS, which offers some reference for physics classroom teaching.

This study extends existing research on content-specific leadership for mathematics and science and educational leadership preparation. Interview data from mathematics and science education faculty reveal that principals should know what questions to ask teachers about instruction, be able to identify high-quality mathematics and science teaching in classrooms, recognize specific considerations related to mathematics and science, and attend to equity in science and mathematics classrooms. Interview data suggest principals support mathematics and science by fostering a culture that values mathematics and science, providing resources, prioritizing depth in instruction, dedicating time for inquiry and exploration, and trusting and empowering teachers with expertise.

Professional development has long been viewed as crucial to sustained improvement in the quality of primary science education. This paper considers professional development beyond the context of a specific program by examining how the science teaching efficacy beliefs and practices vary between teachers who both have and have not engaged with science professional development. This paper reports on a primarily quantitative study wherein a sample of 206 Australian public primary educators responded to an online survey capturing demographic, science teaching efficacy and science teaching practice data. Quantitative data were analysed via descriptive, ANOVA and Chi Square analyses. The supplementary qualitative data were analysed thematically. More participants reportedly not participating in science professional development (n=128) than those that did (n=78), with teachers based in non-metropolitan and disadvantaged schools being proportionally overrepresented in the "No PD" group. The results showed that teachers who reportedly engaged with science professional development showed significantly higher scores on measures of science teaching efficacy, science teaching approaches and curriculum coverage. Professional development attendees were also more likely to use science teaching approaches aligned with the broader goal of improving students' scientific literacy. This research has implications for increasing access to science professional development opportunities for primary educators. It also shows that the benefits commonly associated with specific professional development programs cannot be solely attributed to the characteristics of teachers willing to pursue such opportunities because the non-attendees in this study were still engaged and confident enough to participate in this research project.

The emerging field of genomic medicine offers an opportunity for biology and anatomy teachers to bring the topics of DNA, genetics, molecular processes, and evolution together into one experience. Through the genomic medicine paradigm, students see the unbroken connection between small biological topics such as mutations and their potential connection to disease phenotypes. In this paper, we present as a main example cystic fibrosis, which is an often-studied genetic disease in general biology class, for examination through the genomic medicine lens. Concepts such as genes, the plasma membrane, variation, mutations, the nucleus, and chromosomes can be used in a narrative and visual approach to genetics through the genomic medicine standpoint to engage and connect students with next-generation genomics and with the fundamental unit of life -- the cell. It is through the genomic medicine lens that the cell's context and relationship to the evolving world takes place.

It is widely recognized that we need to prepare students to think with data. This study investigates student interactions with digital data graphs and seeks to identify what might prompt them to shift toward using their graphs as thinking tools in the authentic activity of doing science. Drawing from video screencast data of three small groups engaged in sensor-based and computer simulation-based experiments in high school physics classes, exploratory qualitative methods are used to identify the student interactions with their graphs and what appeared to prompt shifts in those interactions. Analysis of the groups, one from a 9th grade class and two from 11th/12th grade combined classes, revealed that unexpected data patterns and graphical anomalies sometimes, but not always, preceded deeper engagement with the graphs. When shifts toward deeper engagement did occur, transcripts revealed that the students perceived the graphical patterns to be misaligned with the actions they had taken to produce those data. Misalignments between the physical, digital, and conceptual worlds of the investigations played an important role in these episodes, appearing to motivate students to revise either their experimental procedures or their conceptions of the phenomena being explored. If real-time graphs can help foster a sense in students that there should be alignments between their data production and data representations, it is suggested that pedagogy leverage this as a way to support deeper student engagement with graphs.

The Next Generation Science Standards regard biological structures at both the micro and macro levels as a core idea of life sciences and expect students to understand animals have external structures that perform diverse functions. Using the common creature of bees as a case, this study aimed to ascertain teenage students' ideas of bees through their visual representations. A total of 73 seventh-grade students aged approximately 13 years from two classes took part in a draw-bee(s) test (DBT), which requests them to create a drawing of a bee or bees. Then their completed drawings were scored against a tentative rubric of bees' basic external structures. The results highlight that many students hold alternative ideas about bees. Notably, a high number of students fail to depict bees' external structures scientifically, with some morphological features being most often missing, inaccurately numbered, inappropriately shaped, or disproportionately sized in their drawings. Based on these results, some implications are elucidated for improving students' understanding of bees in biological teaching.

Much research attention has been focused on learning through game playing. However, very little has been focused on student learning through game making, especially in science. Moreover, none of the studies on learning through making games has presented an account of how students engage in the process of game design in real time. The present study seeks to address that gap. We report an exploratory embedded case study in which three groups of students in one classroom created a computer game designed to teach peers about climate science, while drawing on scientific knowledge, principles of game design, and computational thinking practices. Data sources were student design sheets, computer video, and audio screen capture while students created their game, and interviews after completing the curriculum unit. A theme-driven framework was used to code the data. A curricular emphasis on systems across climate systems, game design, and computational thinking practices provided a context designed to synergistically supported student learning. This embedded case study provides a rich example of what a collaborative game design task in a constructionist context looks like in a middle school science classroom, and how it supports student learning. Game design in a constructionist learning environment that emphasized learning through building a game allowed students to choose their pathways through the learning experience and resulted in learning for all despite various levels of programming experience. Our findings suggest that game design may be a promising context for supporting student learning in STEM disciplines.

The inquiry-based strategy in science education is widely recommended and incorporated in practical work. However, contextual and intrinsic teaching challenges associated with practical investigations (inquiry-based practical work), occur in resource-constrained physical sciences classrooms in South Africa. The intrinsic challenges have previously been identified from the perspective of the pedagogical content knowledge framework and the concerns-based adoption model. In this article we present a novel approach, investigating the intrinsic challenges from a viewpoint of instructional design. The multi-method technique was used to collect data which was analysed by combining the deductive and the inductive approaches in thematic analysis. The findings consist of intrinsic teaching challenges in the initiation, planning, and implementation phases of practical investigations. Examples of the challenges include practical work being considered to have a confirmatory role, inadequacies linked to addressing learner safety, and unfamiliarity with well-known instructional models. While new challenges were identified, the findings add a new perspective to intrinsic challenges relating to practical investigations in the context of physical sciences education in South Africa. Also, the findings enhance global knowledge about the complexity of intrinsic teaching challenges linked to practical investigations. In addition, the findings inform teacher support while suggesting lines of future research linked to practical investigations in resource-constrained physical sciences classrooms in South Africa and beyond.

This study examined how filters and amplifiers affect pre-service science teachers' pedagogical content knowledge (PCK) in a human and environment unit. The redefined consensus model for PCK and decision-making framework for identifying how personal and extrapersonal factors act as filters and amplifiers were selected as theoretical frameworks. Two pre-service science teachers participated in the study. While pre-interviews were used to determine participants' PCK before teaching, observations and post-interviews were used to reveal participants' PCK after teaching, and how filters and amplifiers influenced PCK. Data were analyzed deductively to examine teachers' PCK including interactions among components and the way filters and amplifiers act on PCK. Constant comparison analysis revealed five general assertions of how filters and amplifiers shaped the decision-making process when these teachers enacted their PCK. First, the number of amplifiers and filters affecting knowledge of instructional strategies (KOIS) was the highest. Second, the number of amplifiers and filters affecting knowledge of curriculum in science was the lowest. Third, the effect of filters and amplifiers on PCK components was idiosyncratic. Fourth, the more (or the less) the map was integrated; the less (or the more) amplifier and filter influenced the PCK. Fifth, the number of personal factors affecting KOIS was highest. Implications are suggested considering the effects of filters and amplifiers on teachers' PCK.

Understanding genetics, an important topic in the study of biology, is critical for scientific literacy in agriculture, health, and forensic investigations. However, it has been observed that teachers find genetics difficult to teach and pupils do not perform well in it. Teachers can use expository teaching or active learning methods, but the secondary school curriculum in Malawi advocates the latter. The aim of this study was to find out how genetics is taught and how teachers justify their choice of method. This study used a multi-case design involving six teachers and observed their Mendelian genetics lessons and asked them to justify their choice of teaching method. The findings show that teachers mostly use expository methods utilizing lecture and question and answer teaching techniques. Contextual factors such as large classes, limited teaching time, and lack of resources were cited as reasons for their choice of expository techniques. In addition, they said that the topic was abstract and learners could not construct their own understanding. Furthermore, they indicated that they did not know what activities to arrange for the learners. The paper discusses the difficulties experienced in implementing active learning methods in teaching genetics and recommends possible avenues for teacher education and further research in Malawi.

This study aimed to examine learners' perspectives on the hybrid learning approach, using printed modules and social media as learning materials to redesign science courses and improve their performances. This study involved 37 students from Tacuyong Sur National High School, 20 from the Grade 9 class and 17 from the Grade 12 Technical Vocational Livelihood (TVL) class in the fourth quarter of the school year 2021-2022. The 5-items multiple-choice test assesses student performance. A survey question determined learners' perspectives on hybrid learning after revising the delivery mode for science courses. Student performances based on their pre-test/post-test revealed the benefits and problems connected with the hybrid learning approach. Program for statistical analysis of sampled data (PSPP) interpreted the survey and student performance. Hybrid learning survey results revealed a practical approach to improve science learners' performances during the COVID-19 pandemic. Data results through teacher-technology innovation demonstrated the effectiveness of hybrid learning techniques to help teachers and curriculum planners redesign course subjects that improve science student performances.

Preservice teachers in science education courses do not generally experience informal, authentic science education practices in their fieldwork. This study used the Scholarship of Teaching and Learning to frame a study that integrated informal science teaching experiences with a university teacher education science methods course. The results showed improvement in participant preservice teachers' ability to teach science content, their self-confidence in teaching science, and their ability to connect what they learned in their methods course in a real-life setting.
