The purpose of this quantitative, causal-comparative study was to determine how, and to what degree learning methods (student-centered or instructor-centered) and gender independently or interactively made a difference in adult student achievement. The Wechsler Individual Achievement Test Third Edition (WIAT-III) was utilized to measure…

This article provides robust empirical evidence for the association between science teachers' pedagogical content knowledge (PCK) and student achievement. Unlike previous studies, we employed two approaches (text-based vs. video-based tests) to assess if, and to what extent, teachers' PCK assessed by these two approaches are related to student…

The increasing use of low-stakes international assessments highlights the importance of test-taking efforts. Previous studies have used self-reported and response time-based measures to examine this effort. Although differences between these measures have been suggested, their association with performances and potential gender gaps remains…

The aim of the study is to investigate the measurement invariance of mathematics self-concept and self-efficacy across 40 countries that participated in the Programme for International Student Assessment (PISA) 2003 and 2012 cycles. The sample of the study consists of 271,760 students in PISA 2003 and 333,804 students in PISA 2012. Firstly, the…

Background: Physical activity (PA) is considered an important factor affecting academic achievement (AA). Different intensities of PA affect mental engagement (ME), which, in turn, affects AA. However, the role of ME in the relationship between PA and AA remains unclear. Objective: This study aimed to examine the mediating and/or moderating role…

Country differences in response styles (RS) may jeopardize cross-country comparability of Likert-type scales. When adjusting for rather than investigating RS is the primary goal, it seems advantageous to impose minimal assumptions on RS structures and leverage information from multiple scales for RS measurement. Using PISA 2015 background…

Mathematics modelling is a vital competency for students of all ages. In this study, we aim to fill the research gap about valid and reliable tools for assessing and grading mathematical modeling problems, particularly those reflecting multiple steps of the modelling cycle. We present in this paper the design of a reliable and valid assessment…

The purpose of this article is to explain the construction of, and potential uses of, a conceptual framework for financial literacy education that has been constructed upon key information drawn from literature reviews of financial literacy education as presented in countries with developed or developing policies and practice in the area. The…

The Cross-Classified Mixed Effects Model (CCMEM) has been demonstrated to be a flexible framework for evaluating reliability by measurement specialists. Reliability can be estimated based on the variance components of the test scores. Built upon their accomplishment, this study extends the CCMEM to be used for evaluating validity evidence.…

School systems around the world use achievement tests to assign students to schools, classes, and instructional resources, including remediation. Using a regression discontinuity design, we study a Florida policy that places middle school students who score below a proficiency cutoff into remedial classes. Students scoring below the cutoff receive…

The purpose of this study was to determine if there is a significant difference in test scores on the Grade Five Reading State of Texas Assessment of Academic Readiness involving male and female students identified as having the characteristics of dyslexia who received early dyslexia intervention and those who received late dyslexia intervention,…

The purpose of this study was to discover the relationship between individual student reading levels to mathematics levels utilizing the State of Texas Assessments of Academic Readiness, STAAR, scores for third- and fourth-grade students before and after the COVID-19 pandemic school closures. The study had four research questions examining third-…

To perform well in the Programme for International Student Assessment (PISA) and respond to rapid social changes, many countries have implemented curriculum reforms. The success of curriculum reform relies on teachers' rational, cognitive and emotional feelings for the challenge of implementation. Teachers' receptivity, growth mindset and grit has…

Implemented was a 45-minute per day Primary Science IDEAS intervention in grades 1-2 integrating reading and writing within science instruction in a multi-year study conducted in 8 experimental and 9 control schools. Results found a significant direct achievement effect in grades 1-2 on both the Iowa Tests of Basic Skills (ITBS) Science and…

The purpose of this mixed-methods study was to examine the relationship between teacher's perceptions of school climate and student achievement of middle school students. Two hundred twenty middle school teachers, from a large urban school district located in the Southwestern region of the US, participated in the "New Jersey School Climate…
