Research on whether teachers can give accurate self-reports in surveys about their mathematics instruction is fairly mixed. Some of that research indicates that teachers can provide some general approximation of their mathematics instruction in survey self-reports, while other studies find very little correlation between teachers' survey responses…

Users assume statistical software packages produce accurate results. In this article, the authors systematically examined Statistical Package for the Social Sciences (SPSS) and Statistical Analysis System (SAS) for 3 analysis of variance (ANOVA) designs, mixed-effects ANOVA, fixed-effects analysis of covariance (ANCOVA), and nested ANOVA. For each…

In multiple-choice items, differential item functioning (DIF) in the correct response may or may not be caused by differentially functioning distractors. Identifying distractors as causes of DIF can provide valuable information for potential item revision or the design of new test items. In this paper, we examine a two-step approach based on…

Reflexivity is a primary requirement for professional work. Our aim was to describe a methodology suitable for detecting the development of reflexive practice through the analysis of 59 Master's degree students' journals. We explore the use and changes of reflexive practice in relation to the settings and activities of the course using analysis of…

The new and rapidly growing field of educational data mining is using the chaff from data collected through normal school activities to explore learning in more detail than ever, and researchers say the day when educators can make use of Amazon.com-like feedback on student learning behaviors may be closer than most people think. Educational data…

This article discusses the application of logit models for the analyses of 2-way categorical observations. The models described are generalized linear models using the logit link function. One of the models is the Rasch model (Rasch, 1960). The objective is to test hypotheses of marginal and conditional independence between explanatory quantities…

Yet today, despite recent welcome additions, relatively little is written about teaching qualitative research. Why is that? This article reports out a relatively simple, yet appealing, pedagogical move, a lesson the author uses to teach qualitative data analysis. Data sorting and categorization, the use of tacit and explicit theory in data…

The Michaelis-Menten rate equation can be found in most general biochemistry textbooks, where the time derivative of the substrate is a hyperbolic function of two kinetic parameters (the limiting rate "V", and the Michaelis constant "K"[subscript M]) and the amount of substrate. However, fundamental concepts of enzyme kinetics can be difficult to…

Regularized generalized canonical correlation analysis (RGCCA) is a generalization of regularized canonical correlation analysis to three or more sets of variables. It constitutes a general framework for many multi-block data analysis methods. It combines the power of multi-block data analysis methods (maximization of well identified criteria) and…

The purpose of this research is to analyze the content of e-portfolios created by students in order to understand their tabulation and ways of displaying content. The analytic result shows that the number of outcome portfolios created by students is more than that of process portfolios. The five types of e-portfolio tabulation, in order of those…

As providers of higher education begin to harness the power of big data analytics, one very fitting application for these new techniques is that of predicting student attrition. The ability to pinpoint students who might soon decide to drop out, or who may be following a suboptimal path to success, allows those in charge not only to understand the…

Well-managed schools are characterised by the presence of properly selected and dedicated educators. The authors argue that the uncontrolled involvement of unions in the selection and promotion of teachers may lead to the infringement of educators' rights and poor performance during the execution of their duties. Findings in the study reveal that…

The role of school psychologists has been debated and contested nationally and internationally for many decades, with an emphasis on the need for a paradigm shift in professional roles. Psychologists may be employed in the private sector, in nongovernmental organisations, in higher education institutions, and by the state. Those employed by the…

In a recent study, Caballero and colleagues conducted a large-scale evaluation using the Force Concept Inventory (FCI) to compare student learning outcomes between two introductory physics curricula: the Matter and Interactions (M&I) mechanics course and a pedagogically-reformed-traditional-content (PRTC) mechanics course. Using a conventional…

Bourdieu's theory of cultural and social reproduction posits that students' habitus--learned behavioural and perceptual dispositions rooted in family upbringing--is a formative influence on how they react to their educational environments, affecting academic practices and academic achievement. Although originally conceived as a "class"…
