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…

This study reviews a selected sample of 274 research articles on ELT, published between 2005 and 2015 in Turkish contexts. In the study, 15 journals in ULAKBIM database and articles from national and international journals accessed according to convenience sampling method were surveyed and relevant articles were obtained. A content analysis was…

Grounded in the whole person perspective of language learners and the concepts of investment and L2 socialization, this qualitative study explores how community service learning (CSL) contributes to international students' L2 practices and identity development. This study finds that CSL creates "a pedagogical contact zone" outside the…

This study advances an experiential learning framework for educators to: (1) identify workforce-building strategies from key healthcare industry informants, (2) strengthen school-industry partnerships, and (3) shape urban high school students' career readiness experiences through curriculum and real life on-the-job training opportunities. Data was…

This study investigated the positive impact of a teaching practice on student learning outcomes in an online MBA program. An instructional project guideline was developed to help online students enhance their achieving required learning objectives corresponding to five categories of Bloom's Taxonomy. The course learning objectives are based on…

Through a year-long study of welfare-to-work students in the community college CalWORKs program, we investigated what self-authorship development looks like by examining developmental progress, and whether there are patterns in development along the three dimensions of self-authorship. Findings demonstrate progress toward self-authorship, but…

Studies reveal that students as well as teachers have difficulties in understanding and learning of decimals. The purpose of this study is to investigate students' as well as pre-service teachers' solution strategies when solving a question that involves an estimation task for the value of a decimal number on the number line. We also examined the…
