Professional teacher collaboration, a fundamental characteristic of lesson study, has been pointed out as a principle of teacher personal and professional growth. This article aims to describe and analyze the development of professional collaboration in a lesson study, highlighting the main stages of this process. The investigation involved six elementary school teachers of Brazilian public schools, in planning, observing, and reflecting on a lesson on the curriculum topic of length measure at grade 4. The participants worked collaboratively planning a lesson about this topic. The methodology is qualitative, with data collected by records and field notes of sessions, conversations, and interviews. The analyses pointed out three remarkable stages of the development of professional collaboration, which constituted the categories of analysis: recognition of collaboration, development of collaboration, and valuing collaboration. The results show that the professional collaboration that developed during the lesson study was facilitated by the dynamics of the different steps of this process and, especially, by the relationship between participants and teacher educators. Collaboration emerged from the activities of planning, teaching, observing, and reflecting on the lesson, and was valued given the encouragement and strengthening of the group insofar as teachers felt confident, encouraged, and welcomed in the group.

Background: Problem-solving as a vehicle to develop independent thinking skills is mostly underestimated and is often either overlooked or not given adequate attention within the existing South African mathematics curriculum. Consequently, numerous learners often display limited skills or lack skills to adequately crack Mathematics problems by applying methods put forward in class. This generally results in under-achievement. Aim: This study aims to explore and emphasise the problem-solving methods applied by Grade 4 learners involved in solving measurement word problems, and to reveal what transpires when the selected learners apply these methods to arrive at meaningful solutions. Setting: Data were collected from a class of 42 Grade 4 learners at a primary school in Cape Town South Africa. Learners were conveniently selected. Methods: A qualitative case study research design was adopted. Data gathering instruments of the study included observing learners solving, measurement word problem activities and focus group interviews. Results: The study revealed that singular methods were applied by Grade 4 learners, such as, adding, multiplying, creating a sketch or diagram, grouping, dividing, subtracting, logical reasoning, guessing and tabulating values. Conclusion: Grade 4 learners are prone to applying methods such as clustering or organising into groups, tabulating numerical values and logical reasoning were all applying mathematically sound methods. Such learners, however, needed a degree of supervision and instruction to indicate the way in which such methods were applied successfully as these methods were not necessarily dealt with in classroom context or in textbooks. Contribution: The findings emphasise the need for tackling learners' limited problem-solving competencies and accentuate the necessity for greater attention to develop and grow methods for optimal and successful solving of problems in context.

This article introduces researchers in the science concerned with developing and studying research methods, measurement, and evaluation (RMME) to the educational data mining (EDM) community. It assumes that the audience is familiar with traditional priorities of statistical analyses, such as accurately estimating model parameters and inferences from those models. Instead, this article focuses on data mining's adoption of statistics and machine learning to produce cutting-edge methods in educational contexts. It answers three questions: (1) What are the primary interests of EDM and RMME researchers?; (2) What is their discipline-specific vocabulary?; and (3) What are the similarities and differences in how the EDM and RMME communities analyze similar types of data?

This study, designed as a basic qualitative research, aims to evaluate the perspectives of Turkish teachers regarding the nationally implemented large-scale assessments in specific subjects. By employing purposive sampling methods, particularly maximum variation sampling, 14 teachers with different seniorities and branches from various high schools were included in the research. Data were collected using a semi-structured interview form prepared by the researcher. Through the application of descriptive analysis, it was found that teachers viewed these assessments more as a preparation for changes in the higher education transition system and as a tool for achieving standardization across the country rather than as an accountability policy instrument. Despite the low-stakes nature of this assessment, it was observed that teachers exhibited responses like those documented in the literature for high-stakes accountability. Additionally, it was found that teachers prepared students for the exams primarily through practice exercises and experienced anxiety before the exams due to the limitation of their autonomy and the comparison of their students and themselves. Furthermore, most participants believed that the assessment results were not effective in determining students' learning, primarily held the students accountable for the results, and considered such assessments as a source of stress. Based on the findings, recommendations were made for practitioners and researchers.

Large-scale assessments play a key role in education: educators and stakeholders need to know what students know and can do, so that they can be prepared for education policies and interventions in teaching and learning. However, a score from the assessment may not be enough--educators need to know why students got low scores, how students engaged with the tasks and the assessment, and how students with different levels of skills worked through the assessment. Process data, combined with response data, reflect students' test-taking processes and can provide educators such rich information, but manually labelling the complex data is hard to scale for large-scale assessments. From scratch, we leveraged machine learning techniques (including supervised, unsupervised, and active learning) and experimented with a general human-centred AI approach to help subject matter experts efficiently and effectively make sense of big data (including students' interaction sequences with the digital assessment platform, such as response, timing, and tool use sequences) to provide process profiles, that is, a holistic view of students' entire test-taking processes on the assessment, so that performance can be viewed in context. Process profiles may help identify different sources for low performance and help generate rich feedback to educators and policy makers. The released National Assessment of Educational Progress (NAEP) Grade 8 mathematics data were used to illustrate our proposed approach.

As part of a study investigating research productivity of sociology PhD students in Australia, an application to the federal government's Department of Education, Skills and Employment (DESE) aimed to establish a baseline count of completed sociology doctorates by university. It was anticipated that university totals might be different from PhD completions within the main sociology teaching units. The government data furnished by this inquiry have proved to be problematic in several ways. The gaps in the data may be explained by the fact that universities report sociology PhDs to DESE in more generic rather than discipline-specific Field of Education (FoE) codes or as PhDs in other disciplines. DESE has either not required or been able to enforce consistent reporting. This raises questions about the time and cost value of these annual compliance efforts. It also limits the value of these data to researchers in charting current and potential future trends.

In the existing literature, scholars have proposed various indices to measure the lexical richness (LR) of English as a foreign language (EFL) writing. However, there are currently issues of redundant indices and inconsistent usage. Attempting to address the research question of which indices are the most sensitive and effective ones to distinguish between different grade levels of Chinese university students' EFL writing, this study aims to put forward a refined and concise model of indices that can truthfully reflect LR in EFL writing. A total of 180 compositions were selected from a Chinese EFL learner corpus: "Spoken and written English corpus of Chinese learners." Scores of 28 LR indices of these compositions were computed using the software "Lexical Complexity Analyzer," "MATTR," and "Coh-Metrix." One-way ANOVA or Welch's ANOVA, depending on the variable's homogeneity of variances, was conducted for each index. Two criteria were applied to determine which index of a measure should be included in the refined model: whether the difference of an index is significant among different grade levels and the effect size of ANOVA. Based on the quantitative results of ANOVAs and qualitative human judgment based on literature, six indices of the six LR measures were included in the refined model: lexical density, lexical sophistication-I, verb sophistication-II, number of different words-expected sequence 50, corrected TTR, and squared verb variation-I. This refined model addresses the issues of redundancy and inconsistency in previous studies, providing a more accurate and efficient tool for assessing LR in EFL writing.

Finite complement clauses (FCCs) are an understudied syntactic structure of L2 advanced academic writing. The present study cross-investigated FCCs in qualitative (QUALI) and quantitative (QUANTI) research articles written by Filipino academic writers (FAWs) in Applied Linguistics (APPLING), Communication (COMM), and Measurement and Evaluation (MEEV). Specifically, it determined the FCCs with the most occurrences across five disciplinary research article sub-registers and identified whether these FCCs differ significantly in terms of frequencies of use. With Hernandez's (2021) framework adapted from Biber and Gray's (2016) study, this research analyzed five FCCs in 42 disciplinary research articles. Major results revealed that verb-controlled that-clauses (with 33.69 as normalized frequency count) outnumbered other FCCs in research article sub-registers across disciplines. They were more recurrent in QUALI and QUANTI APPLING research articles (7.91 and 7.54, respectively) and QUANTI and QUALI COMM research articles (7.34 and 6.96, respectively) than in QUANTI MEEV research articles (3.94). In addition, a significant difference exists between them and other FCCs at the p<0.05 level in terms of frequencies of use. In view of these findings, it can be concluded that verb-controlled that-clauses are the most useful FCCs in APPLING, COMM, and MEEV research articles. Likewise, FAWs across the three disciplines write more informally as signposted by their repeated use of that complementizer with these FCCs controlled by verbs. The study draws its implications for academic writing instruction.

Religion has been associated with human values and competencies needed to shape young people into responsible citizens able to make a positive difference in the lives of others. However, this correlation remains dependent on the context. As the correlation has not yet been investigated in Mauritius, which is a multicultural and multi-ethnic country, this study aims to bridge this knowledge gap using a purely positivist epistemological approach. It will analyze the Mauritius-specific data derived from a public data set which was part of the "Mapping the Terrain" project to examine the correlation between religion and a broad set of human values and competencies, namely forgiveness, individualistic orientation, collectivistic orientation, self-efficacy, problem-solving, meaning-making, sense of belongingness, religiosity/spirituality, hope, life satisfaction, gratitude, emotion, regulation, empathy, and self-regulation. The descriptive analysis and the Structural Equation Model (SEM), developed using the SPSS and AMOS software, revealed that (i) independent of ethnic group, educational stakeholders in Mauritius have a high affinity to most of the human values and competences, and (ii) as compared with others, the Muslim community has a slightly lower affinity to forgiveness, life satisfaction, individualistic orientation, self-efficacy, and problem solving. These data, which represent important baseline information needed to inform policymakers and other educational stakeholders, were used to derive a set of recommendations that will further the development of the key human values and competencies needed to promote harmony in a multicultural and multi-ethnic country.

Nowadays, it is not common to come across sectors that can work and succeed without using information technology (IT). IT has now become a part of organizations' management and strategic decision-making mechanisms. Therefore, organizations make serious investments to develop software and system infrastructures and transfer business processes to digital environments such as cloud technologies. So, they get business resilient while they gain opportunities of spreading their business activities to wide stakeholders and customers. Here it is essential to provide assurance that an organization evaluates, develops, implements, maintains, disposes of its IT systems and manages life cycle of all information and information technology systems properly on all physical and logical environments. However, the most important matter is that an organization's objectives are met by the management practices of its information systems. While organizations carry out their digital transformation at a dizzying speed, organizations should be protected from material and moral damages such as loss of money, loss of commercial confidential information, loss of reputation by protecting the confidentiality, integrity and accessibility of the information assets they own and also comply with legal legislations such as the protection of personal data and intellectual property rights. In order to achieve this, organizations benefit from one or more frameworks, standards or directives that are suitable for their own structures and needs, separately or by integrating them. However, the most important point in this transformation process is the transition of organizations from IT management understanding to IT governance. In other words, IT has now become a part of the strategic decision-making mechanism by rising from the level of support tool to carry out business processes in organizations. When we search the academic literature, frameworks and standards, it is seen that the key elements of IT governance are structures, processes and relational mechanisms. If these three components are set up correctly and fit the organization, it can be assured that IT aligns with and supports the objectives of the organizations and that effective IT governance is achieved in every kind of organizations. In this research, databases such as Web of Science, IEEE, and SCOPUS are scanned and found articles are reviewed in order to make a literature review on IT Governance Mechanisms and Frameworks. Results are evaluated and discussed. By the way, suggestions for further studies were made and advanced researches were shed light on.

Predictive student models are increasingly used in learning environments due to their ability to enhance educational outcomes and support stakeholders in making informed decisions. However, predictive models can be biased and produce unfair outcomes, leading to potential discrimination against certain individuals and harmful long-term implications. This has prompted research on fairness metrics meant to capture and quantify such biases. Nonetheless, current metrics primarily focus on predictive performance comparisons between groups, without considering the behavior of the models or the severity of the biases in the outcomes. To address this gap, we proposed a novel metric in a previous work (Verger et al., 2023) named "Model Absolute Density Distance" (MADD), measuring algorithmic unfairness as the difference of the probability distributions of the model's outcomes. In this paper, we extended our previous work with two major additions. Firstly, we provided theoretical and practical considerations on a hyperparameter of MADD, named "bandwidth," useful for optimal measurement of fairness with this metric. Secondly, we demonstrated how MADD can be used not only to measure unfairness but also to mitigate it through postprocessing of the model's outcomes while preserving its accuracy. We experimented with our approach on the same task of predicting student success in online courses as our previous work, and obtained successful results. To facilitate replication and future usages of MADD in different contexts, we developed an open-source Python package called maddlib (https://pypi.org/project/maddlib/). Altogether, our work contributes to advancing the research on fair student models in education.

The objective of this study was to develop a measure that possesses both reliability and validity in order to evaluate innovative thinking within the realm of education. To achieve this, the instrument's validity and reliability were evaluated through quantitative methods in two distinct phases. A team of educational experts conducted the process of establishing content validity and ensuring that the items on the instrument accurately reflected the intended constructs of creative thinking. Following that, the assessment of concept validity was conducted using confirmatory factor analyses. The aforementioned investigations resulted in the discovery of a five-factor solution consisting of 25 elements, all of which demonstrated scores beyond the crucial threshold. This successful outcome confirmed the presence of distinct factors representing different dimensions of innovative thinking. The study enrolled 1250 students from vocational education institutions as participants. The data obtained from the participants was subjected to principal component analysis and confirmatory factor analysis, leading to the development of a model that exhibited a good match with the empirical data. This indicated the effectiveness of the developed instrument in measuring innovative thinking capacity. In conclusion, the research effectively developed an accurate and dependable tool for evaluating innovative thinking in the realm of education. The gathering of positive data from the participants and meticulous quantitative analyses were responsible for this.

The fact that the mathematics course is abstract, that it is not possible to associate it with daily life, and that it is impossible to concretize abstract expressions causes a prejudice against the this course and leads to a decrease in the academic achievements of students. It is seen that throughout history, various studies have been carried out taking this situation into consideration. A group of these studies is on realistic mathematics education. Realistic mathematics education is an approach that aims to concretize the abstract concepts of mathematics by relating them to real-life situations. The purpose is to make mathematics more understandable by concretizing it. In the study, the subject of calculating the surface area of prisms with the use of realistic mathematics education was taught, and the purpose of the study was to examine the effects of this application. The study group consisted of 20 5th grade students. While determining this group, maximum variety sampling strategy was preferred. In the study, action research, one of the qualitative research methods, was used, and the data were interpreted with the help of descriptive analysis and content analysis. The data collection tools in the study included semi-structured interview forms, video recordings, photos and activity sheets prepared by the students under the guidance of the researcher in accordance with the realistic mathematics education approach. When the findings were examined, it was seen that the students showed a positive development in the meaning and visualization processes; that they could reach mathematical inferences on their own; that they enjoyed the mathematics lesson; and that the realistic mathematics education approach gave positive results on learning. Based on these results, it was suggested that not only the application of the realistic mathematics education approach for different acquisitions but also the inclusion of these activities in the textbooks in accordance with the curriculum will result in improvements in favor of learning.

Background/purpose: Awareness of the mathematical skills and knowledge children possess in their early years is widely accepted. This includes various common positive aspects, not only for educators but also for researchers and policymakers. This study presents a systematic review conducted to meticulously identify empirical studies published in the Scopus-Index Journal database about the mathematical skills children aged 3 to 8 years old have mastered. Materials/methods: This review followed the PRISMA guidelines and the research database comprised of Scopus-indexed journals. The technique followed used "keywords" and Boolean operators. The screening processes included reviewing abstracts, scanning complete texts of published articles, and rejecting those not meeting preset inclusion criteria. Moreover, systematic reviews, meta-analyses, and papers not written in English were also excluded. Of the 801 studies initially identified, a total of 15 empirical studies were included in the systematic review. Results: Children master various math skills from a very young age, mainly in "numbers and operations", but face difficulties in skills related to "algebra" as well as "geometry and measurement". Additionally, several preschoolers' characteristics help to explain the acquisition of these skills, with "age" being the primary factor. Researchers use various research instruments and mainly conduct individual semi-structured interviews. Children's geometry skills and knowledge appear to have been studied to a small extent. The areas of "measurement" and "data analysis and probability" were found to be under active investigation. Conclusion: It is worth noting that not only does a noticeable research gap exist for the math domains of "measurement," "geometry," and "data analysis and probability". Factors that seem to affect young children's math skills, such as "gender", "parents' educational level", and "attendance to a preparatory preschool" need further investigation. The implications of the current study's results extend beyond academia, providing valuable insights that educators and policymakers can leverage to enhance the quality of mathematics education during the early years period.

Neurodiversity refers to the idea that all brains--no matter their differences--are valuable and should be accepted. Attitudes toward the neurodiversity perspective can have real-life impacts on the lives of neurodivergent people, from effects on daily interactions to how professionals deliver services for neurodivergent individuals. In order to identify negative attitudes toward neurodiversity and potentially intervene to improve them, we first need to measure these attitudes. This article describes the development and initial validation of the Neurodiversity Attitudes Questionnaire (NDAQ), including item revision based on expert review, cognitive interviews, systematic evaluation of participants' response process, and analysis of the instrument's internal factor structure using exploratory structural equation modeling. Pilot analysis with 351 individuals mostly living in the United States who were currently working in or intending to pursue helping professions indicates that the NDAQ has construct validity, is well understood by participants, and fits a five-factor structure. While the NDAQ represents the first instrument designed to specifically assess attitudes toward the neurodiversity perspective, further validation work is still needed.

Mixed-mode surveys are popular as they can save costs and maintain (or improve) response rates relative to single-mode surveys. Nevertheless, it is not yet clear how design decisions like survey mode or questionnaire length impact measurement quality. In this study, we compare measurement quality in an experiment of three distinct survey designs implemented in the German sample of the European Values Study: a single-mode face-to-face design, a mixed-mode mail/web design, and a shorter (matrix) questionnaire in the mixed-mode design. We compare measurement quality in different ways, including differences in distributions across several data quality indicators as well as equivalence testing over 140 items in 25 attitudinal scales. We find similar data quality across the survey designs, although the mixed-mode survey shows more item nonresponse compared to the single-mode survey. Using equivalence testing we find that most scales achieve metric equivalence and, to a lesser extent, scalar equivalence across the designs.

Higher education institutions (HEIs) are encountering numerous challenges in today's era of globalization and internationalization. Among these challenges, digital transformation stands out as one of the most demanding, as it involves using ICT to transform business processes. The successful implementation of such systems and related services requires careful management and measurement. To gain deeper insights into the present state of information systems (IS) and digital services in higher education and relevant theory-based models, a systematic literature review and bibliometric analysis were conducted. After the search and screening, this paper systematically reviewed 63 publications to identify various ISs and classify the research conducted to date. This paper highlights a critical gap in the investigation of ISs beyond learning activities, emphasizing the under-researched area of administrative digital services. Furthermore, the paper contributes by highlighting the prevalent use of DeLone and McLean's success model, particularly in combination with TAM/UTAUT, for empirically measuring IS success in higher education. Results also identify a need for greater consistency and rigor in the use of indicators across studies, since there is no evident agreement on indicators used for measuring the success dimensions. Bibliometric analysis on 1791 records underscores the evolving research landscape, with a shift towards evaluating the quality dimension emphasizing the significance of success evaluation. By achieving its primary objective of examining and organizing the relevant scientific literature on IS in higher education, this study contributes to the existing body of knowledge and offers foundational resources researchers and HEIs seeking to implement new ISs or improve their current systems.

Recent publications emphasize the need to take greater account of differences in teaching quality between subjects. The empirical analysis of this topic requires a comparison of teaching quality in different subjects to distinguish generic aspects of teaching quality from subject-specific ones. In this paper, we compare teaching quality in mathematics and German lessons using observational data from primary schools in Switzerland (N[subscript Math] = 319; N[subscript German] = 237). Data were collected using an observation instrument reflecting the teaching dimensions of the MAIN-TEACH model, which was developed based on a synthesis of established observation frameworks. The dimensions of classroom management, motivational-emotional support, selection and implementation of content, cognitive activation, support for consolidation, assessment and feedback, and adaptation were tested for subject-related measurement invariance. With a two-fold measurement invariance approach, differences between the subjects were investigated at both a global and an indicator level. When applying alpha accumulation correction, no significant subject-related differences in factor loadings or intercepts were found. The factorial structure of our data was basically identical for the two subjects. The comparison of latent factor means revealed no mean differences between the subjects. We discuss the implications for both the MAIN-TEACH model and research into subject-related differences of teaching in general.

Mental health conditions are more prevalent in autistic people than non-autistic people. The Strengths and Difficulties Questionnaire is a commonly used screening tool for emotional and behavioural difficulties in autistic children and adolescents. However, few studies have assessed the psychometric properties of the Strengths and Difficulties Questionnaire in populations of autistic people, especially measurement invariance, to examine whether the underlying latent structure is consistent across time or groups. Measurement invariance of the parent-reported Strengths and Difficulties Questionnaire in a nationally representative cohort study was examined: longitudinal invariance (autistic 11-, 14- and 17-year-olds) and group invariance (autistic and non-autistic 17-year-olds). Differential item functioning was explored in the autistic/non-autistic group analysis. The five-factor structure showed inadequate fit, especially in the autistic group; by extension, measurement invariance could not be established. Differential item functioning was observed for several conduct problems, prosocial behaviour and peer problems subscale items, as well as reverse-coded items. Poor structural validity and item-level invariance may confound findings from research within and between populations of autistic and non-autistic adolescents, as well as screening of mental health conditions in autistic adolescents. This research calls for the development and improvement of screening tools for emotional and behavioural difficulties in populations of autistic people while accounting for their heterogeneity.

I review opportunities and threats that widely accessible Artificial Intelligence (AI)-powered services present for educational statistics and measurement. Algorithmic and computational advances continue to improve approaches to item generation, scale maintenance, test security, test scoring, and score reporting. Predictable misuses of AI for these purposes will result in biased scores, construct underrepresentation, and differential impact over time. Recent efforts to develop standards for AI use in testing like those of Burstein are promising. I argue that similar efforts to develop AI standards for educational measurement will benefit from increased attention to the context of test use and explicit commitment to ongoing monitoring of bias and scale drift over time.

I consider recent attempts to establish standards, principles, and goals for artificial intelligence (AI) through the lens of educational measurement. Distinctions are made between generative AI and AI-adjacent methods and applications of AI in formative versus summative assessment contexts. While expressing optimism about its possibilities, I caution that the examples of truly generative AI in educational testing have the potential to be overexaggerated, that efforts to establish standards for AI should complement the Standards for Educational and Psychological Testing and focus attention on the issues of fairness and social responsibility, and that scientific advance and transparency in the development and application of AI in educational assessment may be incompatible with the competitive marketplace that is funding this development.

Purpose: There is little consensus in the literature regarding a) what it means for a school leader to lead with data, and b) how to measure data-informed leadership in a reliable and valid way. This study examines the psychometric properties of an operational measure intended to assess the extent to which a school leader is a data-informed school leader. The measurement invariance, reliabilities and construct and predictive validities of the "Data-Informed School Leadership Survey" (DISL Survey) are assessed using various psychometric statistical techniques. Methods: Using data collected from 155 teachers from 7 public schools in a southern state, the following psychometric statistics used to address our purpose: the Many-Facet Rasch (MFR) Model, Bayesian second-order Confirmatory Factor Analysis (CFA), Bayesian Structural Equation Modeling--Multiple Indicators, Multiple Causes analysis (Bayesian SEM-MIMIC), and reliability analysis. Findings: Results show an adequate fit from all MFR, Bayesian CFA, and MIMIC models and a high reliability (Cronbach [alpha] = 0.98). The DISL Survey instrument exhibits sound psychometric properties. Results likewise confirm the value of using MFR modeling and Bayesian methods to examine the psychometric properties of DISL Survey as a means of improving educational leadership measures. Implications for Research and Practice: Data from this study confirm the validity and reliability of the "Data-Informed School Leadership Survey" (DISL Survey) as an instrument to assess the strengths and weaknesses of Data-Informed School Leadership (DISL) and as a means for providing feedback for improving such leadership. Heretofore a measure for assessing this leadership was non-existent.

The proportion of infants in the United States who are breastfed at 1 year remains well below the Healthy People 2030 target. The health implications of suboptimal breastfeeding durations are significant, including increased risk of childhood leukemia and maternal Type 2 diabetes. Prenatal breastfeeding education provides an opportunity to improve breastfeeding self-efficacy among pregnant individuals and to establish their coping skills in case future breastfeeding problems arise. Although prenatal breastfeeding education is known to improve breastfeeding self-efficacy, characteristics of prenatal breastfeeding education interventions that are successful at increasing breastfeeding duration have not been well defined. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Health Action Process Approach, we conducted a systematic review of the literature examining the impact of prenatal breastfeeding education interventions on breastfeeding duration measured at least 12 weeks postpartum. Twenty-one studies were identified. Prenatal breastfeeding education was most likely to increase breastfeeding duration when education interventions integrated psychological components (Health Action Process Approach coping planning) or were paired with in-person postpartum breastfeeding support. Additional research is needed to examine the role of psychological components in breastfeeding education interventions in diverse populations and to determine the specific psychological intervention components with the greatest impact on breastfeeding duration.

On the surface, the number line may seem like a basic tool with obvious applications. However, using a number line is not always intuitive for students. Students may not recognize significant features such as the size of the unit, how units are represented by iterated equal lengths, or that the accumulation of iterated units is a magnitude of length. In addition, transitioning from counting a set of objects to quantifying iterated lengths on a number line can be confusing for students. In the authors' work with students, they draw students' attention to recognizing what units mean and how units are used on a number line. The authors found that after first defining a unit of length (e.g., from 0 to 1) when measuring or creating a length, students are able to make sense of number and quantity on a number line This article describes the authors' experiences with developing students' understanding of concepts underlying the number line within a measurement context. Using carefully sequenced lessons, the students described how the number line showed the iteration of the same unit. This provided a basis for understanding more sophisticated concepts, such as how a smaller unit will need to be iterated more frequently than a larger unit to measure the same quantity. If students are struggling, reflect on how to introduce the number line and take the time to facilitate a discussion that focuses student attention on the units and lengths, rather than on the tick marks. Use measurement vocabulary, such as unit and length, when discussing the number line. This will help students build a robust and flexible understanding of the mathematics concepts underlying this tool.

Central among a range of reforms and policy measures aimed at enhancing the quality and social cohesion of Norwegian early childhood education and care (ECEC) services is the 2017 "Framework Plan for Kindergartens." In this article, we investigate the policy formation process and how framework plan reform has been carried out by public and private stakeholders at different levels. The reform is explored as institutional layering, referring to theoretical contributions that stress the role of incremental development and gradual institutional change. We ask: What are the policies added, and to what extent do added policies instigate institutional change? This article relies on qualitative document analyses, semistructured interviews, and quantitative survey data. We find high legitimacy for the framework plan in the ECEC sector, and informants broadly regard it as a continuation of earlier versions of the plan. Our analysis further shows that the implementation of the 2017 framework plan reform cannot be viewed in isolation, as it interacts with other reforms, trends, and instruments in the sector. We argue that blending reform design features with existing values and practices adds layers to Norwegian ECEC, instigating change. The analysis points to the need for further research on how national educational reforms are implemented in complex settings and to investigate the relationships between policy design and measures and between policy outcomes and ambitions. The relationships between different measures can be unclear to local implementers. Thus, we stress the importance of considering how reform outcomes depend on intertwined reforms and varying local conditions regarding capacity, norms, and values.

Clathrate hydrates are attractive materials for education because they form from water and familiar compounds, such as carbon dioxide, and are relevant to novel technologies. In this study, an attempt to propose a laboratory experiment was summarized, which used carbon dioxide clathrate hydrate as an educational material with carbon capture technologies as the background of the experiment. The experiment was provided from October 2020 to August 2022 in the "Laboratory Experiments in Energy and Environment Engineering" class for second- and third-year undergraduate students. A total of 90 students, divided into 14 groups and 28 subgroups, performed the experiment. The carbon dioxide clathrate hydrate was formed under low-temperature and high-pressure conditions. Based on the measured temperature and pressure conditions, the amount of formed carbon dioxide clathrate hydrate was calculated as exercise problems. In addition to the exercise problems, the students submitted a report describing the experiments and related discussions. 92% of the students passed the required score to earn the credit for the class. The average score for those who passed the class was 84%. The educational effect was discussed based on the content of the exercise problems and reports. A stirring device to enhance the clathrate hydrate formation was designed and constructed by two students enrolled in "Project Management Practice" for fourth-year undergraduate students. They obtained a 100% score because they successfully constructed the device based on a project management method. The device was used in a laboratory experiment.

This review aimed to identify measurement tools to assess dietary intake and physical activity (PA) among individuals with autism spectrum disorder (ASD) and describe the evidence of validity and availability of each tool. Searches were conducted in PubMed, Embase, CINAHL, and PsycINFO using keywords for ASD, PA, diet, and assessment/measurement (n = 2364 articles). After removing duplicates and title/abstract screening, 212 full-text articles were reviewed, and 113 articles were included for data extraction. The most common dietary and PA assessment tools were identified, and each reviewer independently extracted the data on target population of the assessment tool, type of instrument, evidence on psychometrics validation, constructs measured, and instrument availability. Our findings highlight the need for instruments developed for and/or validated in this population.

Recent decades have seen a rapid acceleration in global participation in formal education, due to worldwide initiatives aimed to provide school access to all children. Research in high income countries has shown that school quality indicators have a significant, positive impact on numeracy and literacy--skills required to participate in the increasingly globalized economy. Schools vary enormously in kind, resources, and teacher training around the world, however, and the validity of using diverse school quality measures in populations with diverse educational profiles remains unclear. First, we assessed whether children's numeracy and literacy performance across populations improves with age, as evidence of general school-related learning effects. Next, we examined whether several school quality measures related to classroom experience and composition, and to educational resources, were correlated with one another. Finally, we examined whether they were associated with children's (4-12-year-olds, N = 889) numeracy and literacy performance in 10 culturally and geographically diverse populations which vary in historical engagement with formal schooling. Across populations, age was a strong positive predictor of academic achievement. Measures related to classroom experience and composition were correlated with one another, as were measures of access to educational resources and classroom experience and composition. The number of teachers per class and access to writing materials were key predictors of numeracy and literacy, while the number of students per classroom, often linked to academic achievement, was not. We discuss these results in the context of maximising children's learning environments and highlight study limitations to motivate future research.

In its original version, control-value theory describes and explains achievement emotions. More recently, the theory has been expanded to also explain epistemic, social, and existential emotions. In this article, I outline the development of the theory, from preliminary work in the 1980s to early versions of the theory and the recent generalized control-value theory. I provide summaries of the theory's evidence-based propositions on antecedents, outcomes, and regulation of emotions, including the fundamentally important role of control and value appraisals across different types of human emotions that are relevant to education (and beyond). The theory includes descriptive taxonomies of emotions as well as propositions explaining (a) the influence of individual factors, social environments, and socio-cultural contexts on emotions; (b) the effects of emotions on learning, performance, and health; (c) reciprocal causation linking emotions, outcomes, and antecedents; (d) ways to regulate emotions; and (e) strategies for intervention. Subsequently, I outline the relevance of the theory for educational practice, including individual and large-scale assessments of emotions; students', teachers', and parents' understanding of emotions; and change of educational practices. In conclusion, I discuss strengths of the theory, open questions, and future directions.

The consistency of psychometric properties across waves of data collection provides valuable evidence that scores can be interpreted consistently. Evidence supporting the consistency of psychometric properties can come from using a longitudinal extension of item factor analysis to account for the lack of independence of observation when evaluating the cross-wave properties. In this study, we demonstrate how to conduct and interpret a longitudinal examination of psychometric properties. This demonstration uses data on the Comprehensive Measure of Meaning across two waves of data collection. A simplified, structured set of R syntax for analyses is provided, and all remaining code is freely available in the accompanying Open Science Framework repository.

Recent criticisms of large-scale summative assessments have claimed that the assessments are biased against historically excluded groups because of the assessments' lack of cultural representation. Accompanying these criticisms is a call for more culturally responsive assessments--assessments that take into account the background characteristics of the students; their beliefs, values, and ethics; their lived experiences; and everything that affects how they learn and behave and communicate. In this paper, we present provisional principles, based on a review of research, that we deem necessary for fostering cultural responsiveness in assessment. We believe the application of these principles can address the criticisms of current assessments.

Research on growth mindset, the belief that one's cognitive abilities are malleable and can be developed through dedication and practice, has received considerable media attention and influenced educational policy and practice. However, mindset theory and measurement have also drawn criticism. In the present paper, we add a cautionary note pertaining to the conceptualization and measurement of growth mindset. Through a critical reanalysis of a large-scale representative study of adolescents from the US (N = 15,362), we show that a growth (i.e., forward-keyed) and a fixed (i.e., reverse keyed) mindset item from a widely used scale are only moderately correlated (r = -0.31). Further, we demonstrate that the two items are very differently related with a range of educationally relevant criteria such as learning engagement and self-efficacy, and sociodemographic characteristics such as sex. This leads us to conclude that the growth and fixed mindset items are not mutually interchangeable (apart from keying) indicators of a unidimensional construct that has fixed and growth mindset at its opposing poles. Which items researchers choose to measure mindset (fixed, growth, or a blend thereof) may therefore have a significant impact on the findings they obtain. Our insights highlight the need for greater attention to the conceptual foundations and measurement of mindset in future studies.

This study uses evidence from a longitudinal survey (PISA Plus, Germany) to examine the potential of bias in international large-scale assessments (ILSAs). In PISA Plus, participation was mandatory at the first measurement point, but voluntary at the second measurement point. The study provides evidence for relevant selection bias regarding student competencies and background variables when participation is voluntary. Sample dropout at the second measurement point was related to characteristics such as family background, achievement in mathematics, reading and science, and other student and school demographic variables at both the student and school levels, with lower performing students and those with less favorable background characteristics having higher dropout frequencies, from which higher dropout probabilities of such students can be inferred. We further contrast the possibilities for addressing non-response through weight adjustments in longitudinal surveys with those in cross-sectional surveys. Considering our results, we evaluate and confirm the validity and appropriateness of strict participation rate requirements in ILSAs. Likely magnitudes of bias in cross-sectional studies in varying scenarios are illustrated. Accordingly, if combined participation rates drop below 70%, a difference of at least one-fifth of a standard deviation in an achievement score between non-respondents and participants leads to relevant bias. When participation drops below 50%, even a very small difference (one-tenth of a standard deviation) will cause non-negligible bias. Finally, we conclude that the stringent participation rate requirements established in most ILSAs are fully valid, reasonable, and important since they ensure a relatively low risk of biased results.

Predictive modelling in the education domain can be utilised to significantly improve teaching and learning experiences. Massive Open Online Courses (MOOCs) generate a large volume of data that can be exploited to predict and evaluate student performance based on various factors. This paper has two broad aims. Firstly, to develop and tune several Machine Learning (ML) models to perform classification tasks on the dataset to predict student performance, including Linear Regression, Logistic Regression, Random Forests, K-Nearest Neighbours, and more. Secondly, to evaluate the efficacy of these ML models and identify those which are best suited to this task. The categories of data utilised in achieving these aims include (i) demographic information, (ii) academic background, and (iii) interaction with MOOC course materials. The research procedure comprises five phases: data exploration to analyse the dataset, feature engineering which involves discerning the most important features and converting them into a format decipherable by the ML models, model building, model evaluation by measurement of accuracy, and subsequent comparative evaluation between the different models. The results achieved in this study are expected to have implications on how MOOC platforms utilise data to improve user experience. As indicated by the findings of this study, the data collected by these platforms may be used to predict performance with accuracy of over 77%; this extracted information can be exploited to enhance educational theory or practices in the context of MOOCs, for instance by implementing varying teaching methodologies or providing different types of resources based on predicted performance.

Autism screening questionnaires are sometimes used as a measure of "autism-associated traits" in samples drawn from the general population, even though such tools are primarily developed and designed for use in samples of children diagnosed with or being assessed for autism. Here, we explore the psychometric properties of the Social Communication Questionnaire (SCQ) current version reported at age 8 in a large population-based sample. Using data from the Norwegian Mother, Father and Child Cohort study (MoBa), we perform exploratory (N = 21,775) and confirmatory (N = 21,674) factor analyses on items and compare our results with previously suggested factor structure models of the SCQ. Furthermore, we test for measurement invariance across sex and registry-ascertained autism diagnostic status (N[subscript diagnosed] = 636). A 5-factor model provided best fit to the data in both children with and without autism diagnoses, though with some qualitative differences in what the factors represent across these groups. This model performed largely consistently across boys and girls in the general population. Taken together, the SCQ's measurement properties must be carefully considered when it is used in population-based samples and measurement invariance testing of other autism screening tools used in similar contexts is warranted.

Children with developmental disabilities lack sufficient physical activity in their daily lives. The purpose of this study was to see if children with developmental disabilities who participated in stair-climbing exercises had better physical performance and health status than children with developmental disabilities who did not. This study adopted a pre-and-post-test experimental design, enrolling 30 subjects (experimental group, 15; control group, 15) with developmental disabilities aged 5-7 years from pediatric rehabilitation treatment departments of two regional teaching hospitals in Taiwan. The experimental group received stair-climbing exercises and physical therapy twice a week for eight consecutive weeks. The primary outcomes were health-related physical fitness assessment items, including body composition (body mass index: BMI), cardiorespiratory fitness (stair-climbing test), muscular fitness (knee-bend sit-ups), and flexibility (Chair Sit and Reach Test). The post-test measurements of BMI, cardiorespiratory fitness, sit-ups, and muscular flexibility of children in the experimental group were significantly better than the pre-test measurements. The stair-climbing exercise training results for cardiorespiratory fitness, muscular fitness, and muscular flexibility in the experimental group were significantly better than those in the control group. Stair-climbing exercise improves the physical fitness of children with developmental disabilities. The results of this study suggest that children with developmental disabilities should be encouraged to engage in this convenient and easy stair-climbing exercise to improve physical performance and health status.

Fit indices are descriptive measures that can help evaluate how well a confirmatory factor analysis (CFA) model fits a researcher's data. In multigroup models, before between-group comparisons are made, fit indices may be used to evaluate measurement invariance by assessing the degree to which multiple groups' data are consistent with increasingly constrained nested models. One such fit index is an adaptation of the root mean square error of approximation (RMSEA) called RMSEA[subscript D]. This index embeds the chi-square and degree-of-freedom differences into a modified RMSEA formula. The present study comprehensively compared RMSEA[subscript D] to [delta]RMSEA, the difference between two RMSEA values associated with a comparison of nested models. The comparison consisted of both derivations as well as a population analysis using one-factor CFA models with features common to those found in practical research. The findings demonstrated that for the same model, RMSEA[subscript D] will always have increased sensitivity relative to [delta]RMSEA with an increasing number of indicator variables. The study also indicated that RMSEA[subscript D] had increased ability to detect noninvariance relative to [delta]RMSEA in one-factor models. For these reasons, when evaluating measurement invariance, RMSEA[subscript D] is recommended instead of [delta]RMSEA.
