This study examined 10th-grade students' use of theory and evidence in evaluating a socio-scientific issue: the use of underground water, after students had received a Science, Technology and Society-oriented instruction. Forty-five male and 45 female students from two intact, single-sex, classes participated in this study. A flow-map method was used to assess the participants' conceptual knowledge. The reasoning mode was assessed using a questionnaire with open-ended questions. Results showed that, although some weak to moderate associations were found between conceptual organization in memory and reasoning modes, the students' ability to incorporate theory and evidence was in general inadequate. It was also found that students' reasoning modes were consistent with their epistemological perspectives. Moreover, male and female students appear to have different reasoning approaches.

In the discussion of the inclusion of generic skills in courses, the voices of employers, universities and government have been clearly heard. However, the undergraduate student voice has been largely missing. This paper outlines the results of a survey of staff and undergraduate students. Part A of the survey asked participants to rate a set of skills in terms of their importance. Part B of the survey asked participants to add other skills that they considered important. The student results demonstrate significant year effects. For example higher-order skills such as critical thinking are rated more important at third year than at first year. Comparisons of the staff data and student data show that student perceptions match staff perceptions more closely at third-year level than at first year. When all the results are considered in the broader context of our courses, there appears to be a strong link between students' perception of the importance of skills and the degree to which the skills are assessed.

Secondary school chemical education has a problem: namely, the seeming irrelevance to the pupils of chemistry. Chemical education prepares pupils for participation in society. Therefore, it must imply a model of society, of chemistry, and of the relation between them. In this article it is hypothesized that logical positivism currently offers this model. Logical positivism is a philosophy of science that creates a divide between science and society. It is therefore further hypothesized that the adoption of logical positivism causes chemistry's lack of relevance in chemical education. Both hypotheses could be confirmed by an analysis of a grade nine course.

The Programme for International Student Assessment (PISA) is an international study coordinated by governments of participating countries, through the Organisation for Economic Co-operation and Development (OECD). In 2000, a total of 265,000 students from 32 countries took part in PISA. The main aim of PISA is to assess how well 15-year-old students are prepared to meet the challenges of today's and tomorrow's knowledge societies. The assessment is forward looking, focusing on young people's ability to use their knowledge and skills to meet real-life challenges, rather than mastering a specific school curriculum. Assessing young people at the end of their compulsory education is regarded as providing valuable insights into the performance of basic education systems (OECD, 1999, 2001). In this Special Issue, the rich data collected in the OECD PISA 2000 study will be exploited in various secondary analyses. These analyses mainly focus on socio-economic and cultural factors related to or associated with learning outcomes in reading and science. Some articles compare educational systems and cultures in all the Nordic countries, while others focus on two or only one of the countries. The authors of the articles in this issue work as researchers in the national PISA teams of the Nordic countries, which all take part in the PISA programme.

Children from seven classes representing the year groups in a primary school were interviewed in groups of three or four to find out their understanding and views on issues related to the environment and science. The large majority showed considerable interest and concern about environmental issues related to their experience and understanding, drawn from school and influences outside of the school, though most showed limitations and contradictions in their understanding of the issues. The children's understanding of science was mainly limited to their experience of the subject at school and few showed any understanding of the impact of science on society or the environment. Examples of children's cognitive and moral development of environmental issues are presented, including features of phases in the development, as identified from the interviews. The implications for teaching science and environmental education are discussed.

This study investigates the various conceptions held by K-8th Korean grade students regarding the 'changes of state' and the 'conditions for changes of state'. The study used a sample of five kindergarteners, five secondgrade students, five fourth-grade students, five sixth-grade students, and five eighth-grade students. The 25 students attend schools in a rural district of South Korea. Some activities that involved a change in the state of water, including condensation, solidification, and melting, were chosen from K-8th grade science textbooks and attempted by the students. Subsequently, we conducted interviews with the students. While most kindergarteners and second-grade students were able to perceive the phenomena involving changes of state, they were unable to express conceptions related to the changes of state and the conditions under which the state the changes. The upper-grade students, on the other hand, had some conception of the invisible gas state. Most of these students held conceptions about the boiling water's change of state from liquid to gas, but few of them held conceptions about the changes of state involving condensation. Most students understood heat and temperature as conditions of the changes of state, but only applied the heat concept to situations involving rising temperatures. In situations involving cooling, students applied the temperature concept. The younger students understood the concept of heat without understanding the concept of temperature.

Postgraduate student teachers' conceptions of sustainable development were elicited using a questionnaire completed by the entire cohort of geography (N = 21) and science (N = 40) students starting the University of Oxford Post Graduate Certificate in Education (PGCE) secondary course. Responses were analysed in three ways: (i) development of categories to capture features of sustainable development; (ii) scrutiny of individual responses for the presence or absence of key features (specifically environmental, economic and social factors); and (iii) in contrast to these grounded approaches, examination of the responses in light of a pre-specified framework. Notable findings were: (i) the large numbers recognizing the centrality of environmental (87%), economic (69%) and social (49%) factors--about a third highlighted all three factors (the geographers significantly more so than the scientists), while a further third mentioned two of them; (ii) when compared with the pre-specified framework, the aspects of sustainable development largely missing were to do with preservation of diversity, and with uncertainty and precaution in action; (iii) only one response contained an aesthetic element; and (iv) when comparing education for sustainable development with environmental education, the most frequent view identified the former as broader. The findings are related to contemporary literature in the field and some implications for PGCE learning are considered.

This research study investigated the attitudes toward science of 8th-grade students in Australia, Canada, Cyprus, and Korea, based on recent TIMSS data, and suggests a model of family and school influences on their attitudes. The structural equation model contained 3 exogenous constructs--familys educational background, aspiration, school climate--and 2 endogenous constructs--teaching and student attitudes toward science. Educational background, aspiration, and school climate were shown to have a direct effect on attitudes, while teaching was shown to directly affect attitudes and to be affected by aspiration and school climate.

Hartnell College is an accredited California Community College serving Salinas and the Salinas Valley, a vast 1,000 square mile agricultural region. The district is characterized by large numbers of migrant workers and their families, chronically high unemployment, high rates of poverty, and low educational attainment. Hartnell's 10,000 students are 67% minority, 52% Latino/a, and 82% first generation college students. Nearly 41% of the College's students are nonnative English speakers. Hartnell's Latino students face serious obstacles to postsecondary success, and far too few Latinos enroll and succeed in mathematics, science, and technology fields. Through Hartnell's MESA program, enrollment in many math and science courses have increased. More significantly, data suggests that students participating in MESA Academic Excellence Workshops have averaged a full grade increase as compared to similar students not participating in the workshops. Hartnell College's MESA program is on a static budget, and the college has expanded and leveraged program services by linking it to several on- and off-campus outreach and student support services programs. Hartnell College won the 2003 Bellwether Award in the Planning, Governance, and Finance category in recognition of this effort.

Applications in engineering, science and technology within undergraduate programmes can be difficult for students to understand. In this paper, new results are presented which go some way to demonstrate and explain the problems faced by students in linking mathematical models to real-world applications. The study is based on student responses to multiple-choice questionnaires on mathematical modelling problems, student reflective questionnaires and subsequent interviews. The processes used by students to solve such problems are classified and links between these process levels, credit and seven other behavioural descriptors are discussed.

The sixth-order wave equation governing the propagation of one-dimensional acoustic waves in a viscous, heat conducting gaseous medium subject to relaxation effects has been considered. It has been reduced to a system of lower order equations corresponding to the finite speeds occurring in the equation, following a method due to Whitham. The lower order equations are much simpler and easier to solve than the original equation. As an illustration, the problem of harmonic wave propagation due to oscillations of a planar wall has been considered, and analytical expressions for the damping coefficients and wave speeds have been obtained.

Purpose: The purpose of this study was to understand nine physical education (PE) teachers' experiences with an asynchronous professional development module focused on science, technology, engineering, and mathematics (STEM) integration, and the barriers they perceived to integrating STEM into PE. Methods: Semistructured interviews, pre- and post open-ended questionnaires, and discussion board posts were analyzed through a collaborative coding process. Trustworthiness was increased by using a peer debriefer, multiple coders, negative case checks, and data triangulation. Results: Four themes describe the experiences of PE teachers learning to integrate STEM into PE: teacher's knowledge about technology and STEM, barriers to PE teachers in integrating STEM, "We're already integrating STEM," and issues in professional development. Discussion/Conclusion: STEM integration is possible if PE teachers are provided time and opportunities to work with content experts to learn STEM concepts and have STEM be a by-product of PE lessons rather than the sole focus of the lesson.

Criteria for recognizing and rewarding scientists primarily focus on individual contributions. This creates a conflict between what is best for scientists careers and what is best for science. In this article, we show how the theory of multilevel selection provides conceptual tools for modifying incentives to better align individual and collective interests. A core principle is the need to account for indirect effects by shifting the level at which selection operates from individuals to the groups in which individuals are embedded. This principle is used in several fields to improve collective outcomes, including animal husbandry, team sports, and professional organizations. Shifting the level of selection has the potential to ameliorate several problems in contemporary science, including accounting for scientists diverse contributions to knowledge generation, reducing individual-level competition, and promoting specialization and team science. We discuss the difficulties associated with shifting the level of selection and outline directions for future development in this domain.

The tutelage of our mentors as scientists included the analogy that writing a good scientific paper was an exercise in storytelling that omitted unessential details that did not move the story forward or that detracted from the overall message. However, the advice to not get lost in the details had an important flaw. In science, it is the many details of the data themselves and the methods used to generate and analyze them that give conclusions their probative meaning. Facts may sometimes slow or distract from the clarity, tidiness, intrigue, or flow of the narrative, but nevertheless they are important for the assessment of what was done, the trustworthiness of the science, and the meaning of the findings. Nevertheless, many critical elements and facts about research studies may be omitted from the narrative and become hidden from scholarly scrutiny. We describe a bakers dozen shortfalls in which such elements that are pertinent to evaluating the validity of scientific studies are sometimes hidden in reports of the work. Such shortfalls may be intentional or unintentional or lie somewhere in between. Additionally, shortfalls may occur at the level of the individual or an institution or of the entire system itself. We conclude by proposing countermeasures to these shortfalls.

At many research-intensive universities in North America, there is a disproportionate loss of minoritized undergraduate students from Science, Technology, Engineering, and Mathematics (STEM) majors. Efforts to confront this diversity, equity, and inclusion (DEI) challenge, such as faculty adoption of evidenced-based instructional approaches that promote student success, have been slow. Instructional and pedagogical change efforts at the academic department level have been demonstrated to be effective at enacting reform. One potential strategy is to embed change agent individuals within STEM departments that can drive change efforts. This study seeks to assess whether tenure-track, teaching-focused faculty housed in STEM departments are perceived as influential on the instructional and pedagogical domains of their colleagues. To answer this, individuals across five STEM departments at large, research-intensive campuses identified faculty who were influential upon six domains of their instruction and pedagogy. Social network analysis of individuals in these departments revealed heterogeneity across the instructional domains. Some, like the teaching strategies network, are highly connected and involve the majority of the department; while others, like the DEI influence network, comprise a significantly smaller population of faculty. Importantly, we demonstrate that tenure-track, teaching-focused faculty are influential across all domains of instruction, but are disproportionately so in the sparsely populated DEI influence networks.

Biomechanics as a discipline is ideally placed to increase awareness and participation of girls and women in science, technology, engineering, and mathematics. A nationwide Biomechanics and Research Innovation Challenge (BRInC) centered on mentoring and role modeling was developed to engage high school girls (mentees) and early-mid-career women (mentors) in the field of biomechanics through the completion of a 100-day research and/or innovation project. This manuscript describes the development, implementation, and uptake of the inaugural BRInC program and synthesizes the research and innovation projects undertaken, providing a framework for adoption of this program within the global biomechanics community. Eighty-seven high school girls in years 9 and 10 (age range: 14–16 y) were mentored in teams (n = 17) by women in biomechanics (n = 24). Using a design thinking approach, teams generated solutions to biomechanics-based problem(s)/research question(s). Eight key reflections on program strengths, as well as areas for improvement and planned changes for future iterations of the BRInC program, are outlined. These key reflections highlight the innovation, impact, and scalability of the program; the importance of a program framework and effective communication tools; and implementation of strategies to sustain the program as well as the importance of diversity and building a sense of community.

William Leybourn (1626 – 1716) was a printer, author, teacher, surveyor, and mathematician. The occupation of “printer” is often associated with passivity: a simple artisan whose sole focus is to bring books to sale and therefore a stranger to the knowledge contained within the books. This paper seeks to revisit this view, showing that William Leybourn was the exact opposite of a passive printer. He introduced to the English public the works of crucial protagonists of the European scientific community (including the works of Galileo Galilei), promoted debates among scholars and natural philosophers, and presented complex topics previously reserved for academic disputations in a manner accessible to a more general audience. Employing both traditional historical research and tools in Digital Humanities, the paper discusses Leybourn’s works as an example of a conceptually and methodologically novel approach to the study of intellectual networks. This bottom-up approach recenters traditionally peripheral figures, such as Leybourn, and reveals crucial social, economic, and political aspects of early modern European cultural and intellectual debates.

Four experiments investigated the perceived virtue of curiosity about religion. Adults from the United States made moral judgments regarding targets who exhibited curiosity, possessed relevant knowledge, or lacked both curiosity and knowledge about religion and comparison topics (e.g., science). Participants attributed greater moral goodness to targets who displayed curiosity compared with targets who were ignorant or knowledgeable about the domain. This preference was consistent across Jewish, Protestant, Catholic, and other Christian participants but was absent when atheists evaluated religious curiosity. Perceptions of effort partially mediated judgments: Participants viewed curious characters as exerting more effort and consequently rated them as more moral. To test causality, we manipulated perceptions of effort and showed that participants viewed curious characters who exerted effort as particularly moral. This work fosters novel insights into the perceived virtue of curiosity and further illuminates similarities and differences between religious and scientific cognition.

Mentorship has been widely recognized as an effective means to promote student learning and engagement in undergraduate research experiences. However, little work exists for understanding different mentors perceived approaches to mentorship, including mentorship of students from backgrounds and educational trajectories not well represented in science, technology, engineering, and mathematics (STEM). Transfer students, in particular, face unique trajectories in their pursuit of research opportunities, yet few studies investigate how mentors describe their approaches to supporting these students. Using semistructured interviews, this study examines how mentors approach mentoring students from diverse backgrounds as research trainees, with an emphasis on transfer students. First, using phenomenography as an analytical approach, we identified four categories describing variations in how mentors reflected upon or accounted for the transfer student identity in their approaches. We find that research mentors vary in their understanding and exposure to the transfer student identity and may have preconceived notions of the transfer student experience. Second, we present vignettes to illustrate how mentors approaches to the transfer student identity may relate or diverge from their general approaches to mentoring students from different backgrounds and identities. The emerging findings have implications for developing effective mentorship strategies and training mentors to support transfer students.

Machine learning (ML) methods are proliferating in scientific research. However, the adoption of these methods has been accompanied by failures of validity, reproducibility, and generalizability. These failures can hinder scientific progress, lead to false consensus around invalid claims, and undermine the credibility of ML-based science. ML methods are often applied and fail in similar ways across disciplines. Motivated by this observation, our goal is to provide clear recommendations for conducting and reporting ML-based science. Drawing from an extensive review of past literature, we present the REFORMS checklist (recommendations for machine-learning-based science). It consists of 32 questions and a paired set of guidelines. REFORMS was developed on the basis of a consensus of 19 researchers across computer science, data science, mathematics, social sciences, and biomedical sciences. REFORMS can serve as a resource for researchers when designing and implementing a study, for referees when reviewing papers, and for journals when enforcing standards for transparency and reproducibility.

Populists’ ideological opposition to global governance is well recognized, yet whether and how these actors systematically undermine international organizations (IOs) remains unclear. We argue that a keymeans by which populists warp global governance is by distorting scientific information, which is necessary for global responses to many public health and environmental issues. Populists are motivated to withhold or misreport scientific information due to their anti-elite, pro-state sovereignty views. Using new data on the source and quality of information provided to IOs, we find that populist leaders are significantly less likely to provide scientific information to these organizations than other types of leaders. When they do offer such data, it is less accurate than the information supplied by other sources. Our findings suggest that populism may stymie international institutions’ ability to govern in areas of pressing international concern.
