Despite limiting access to applicants from underrepresented racial and ethnic groups, the practice of using hard or soft Graduate Record Examination (GRE) cutoff scores in physics graduate program admissions is still a popular method for reducing the pool of applicants. The present study considers whether the undergraduate institutions of…

Diversifying the STEM workforce is a national priority, yet white males continue to dominate the ranks of professional scientists and engineers in the United States. This is partly due to disparities in academic success for women and minoritized students in prerequisite introductory STEM courses, leading to higher attrition from B.S. degree…

The main aim of this research was to measure 10th and 12th grade students' biological conceptual understanding and competences through their upper secondary school studies. Data collection started at the beginning of the upper secondary school biology studies in the 10th grade. The same students participated in this research when they were in the…

This paper discusses the effectiveness of the inverted classroom implemented in a pre-university physics classroom on topics of classical mechanics. Inverted classroom moves from traditional lectures to providing students with pre-recorded lectures and other materials such as videos, online quizzes and online exercises to foster independent…

Computer technology (CT) for student use is a popular avenue for school districts to pursue in their goal to attain higher academic achievement. The purpose of this study is to examine the use of iPads in a one-to-one setting, where every student has his own device 24/7, to determine the effects, if any, on academic achievement in the areas of…

Here we demonstrate the benefits of a new curriculum for introductory calculus-based physics that motivates classical mechanics using a modified version of Hamiltonian mechanics. This curriculum shifts the initial focus of instruction away from forces and the associated vector mathematics, which are known to be problematic for students, to the…

Gateways-ND is a 5-year, National Science Foundation-funded effort directed toward three goals: maximizing the instructional effectiveness of postsecondary STEM (science, technology, engineering, and mathematics) faculty by building expertise in learner-focused practice, positively impacting student success in STEM-based "gateway"…

It is imperative to note that the study reported on attempted to reimagine a link between underachievement and attrition in curriculum implementation. The contextual factors that affected achievement and resulted in attrition were worth further scrutiny. The study further reported the results of a pilot study conducted in the Western Cape, South…

Background: Beyond ability, traits related to perseverance, such as grit and self-discipline, are associated with adaptive educational outcomes. Few studies have examined the independent effects of these traits on outcomes and the mechanisms involved. Aims: This study estimated parameters of a process model in which grit-perseverance of effort…

Over the last decade, the "gender gap" in physics conceptual inventory scores has been extensively studied by the physics education research community. Researchers have identified many factors that influence the overall differences in post-test scores between men and women. More recently, it has been shown that the Force Concept…

The study investigated the relationship between South African Grade 9 teachers' and learners' perceptions and attitudes with their mathematics achievement. The study used a secondary analysis of the TIMSS 2015 mathematics data, guided by the conceptual framework model of Scheerens (2000). The quantitative data collected through teachers' and…

This article describes the results of a study into students' experiences of independent research project work in science. Independent research projects are projects in which students are supervised (usually by a teacher, scientist or both) to work independently on a scientific problem or question over an extended period. We collected data from 39…

The research study sought to determine the effect of tailored animated motion sequences on teaching, performance and visual literacy in Biology learners. The animations were developed as per the Grade 8 Biology syllabus hence referring to the term 'tailored motion graphic's' using the ADDIE design model. This mixed-methods study included a series…

The International Association for the Evaluation of Educational Achievement's (IEA) mission is to enhance knowledge about education systems worldwide and to provide high-quality data that will support education reform and lead to better teaching and learning in schools. In pursuit of this aim, it conducts and reports on major studies of student…

A primary purpose of cognitive diagnosis models (CDMs) is to classify examinees based on their attribute patterns. The Q-matrix (Tatsuoka, 1985), a common component of all CDMs, specifies the relationship between the set of required dichotomous attributes and the test items. Since a Q-matrix is often developed by content-knowledge experts and can…
