Despite a number of theories in circuit analysis, little is known about the behaviour of ideal equal voltage sources in parallel, connected across a resistive load. We neither have any theory that can predict the voltage source that provides the load current, nor is there any method to test it experimentally. In a series of experiments performed…

Many of us embrace the order and beauty in mathematics. The order of operations is an iconic mathematics topic that seems untouchable by time, reform, or mathematical discoveries. Yet, think for a moment about a commonly heard statement in teaching the order of operations: "You work from left to right." At another point in the…

Anyone who has taught introductory physics should know that roughly a third of the students initially believe that any object at rest will remain at rest, whereas any moving body not propelled by applied forces will promptly come to rest. Likewise, about half of those uninitiated students believe that any object moving at a constant speed must be…

The Object-Oriented Programming (OOP) technique is nowadays the most popular programming technique among tertiary education institutions. However, learning OOP is a cognitively demanding task for undergraduate students. Several difficulties and misconceptions have been recorded in the literature for both OOP concepts and languages, mainly Java.…

Learning content-specific vocabulary is critical for students especially in content areas such as science. However, direct vocabulary instruction is lacking in many classrooms. This case study examined vocabulary instructional strategies within a 6th grade science classroom. The following questions were addressed: (1) What science vocabulary…

Genetics can be a difficult topic to teach and learn in a traditional classroom. The objective of this qualitative classroom action research was to examine the effectiveness of a blend of problem-based learning (PBL) with scientific argumentation to improve student understanding of basic genetics. The research participants were grade 9 Bhutanese…

This article reports on the findings of a qualitative study on the causes of school decline at two schools located in Chipinge Education District, Zimbabwe. Specifically, the study focussed on schools that were previously known for excellent academic learner performance but had since declined. The data was generated through semi-structured…

The goal of this study is to gain a better understanding of the experiences of Palestinian-Israeli minority teachers when teaching at majority state Hebrew secular schools in Israel. Specifically, the objective is to describe and analyze the role of the teachers' work-related experiences in shaping their sense of self-efficacy, job satisfaction,…

This study demonstrates how stakeholders' treatment of English language as the sole marketable/saleable commodity in educational setting can have implications for multilingualism and existing linguistic diversity in Pakistan. Language commodification refers to the valuation of languages as marketable/saleable commodities and their relative…

With the expansion of higher education and the growth of online course offerings in Sub-Saharan Africa, there is a critical need to support faculty in developing the necessary skills to teach effectively online. The purpose of this qualitative, single-case study was to examine the nature of the discourse in which faculty members engaged within a…

Recent research on the overdistribution principle implies that episodic memory is infected by conjunction illusions. These are instances in which an item that was presented in a single context (e.g., List 1) is falsely remembered as having been presented in multiple contexts (e.g., List 1 and List 2). Robust conjunction illusions were detected in…

Scholars have advocated for critical approaches to language education (e.g., Del Valle, 2014; Leeman & Serafini, 2016), including those that promote the development of "Critical Language Awareness, CLA" (e.g., Alim, 2010; Leeman, 2018). The goal is to develop students' critical knowledge of the cultural, political, and social…

This article argues that the organizational structure and culture of schools may impede the prevention of violence in America's schools, specifically threat assessment and management for students of concern. The data come from a qualitative case study of a school shooting where two students died; the data include deposition testimony from 12…

Prior studies have shown that students have difficulty understanding the role of mutation in evolution and genetics. However, little is known about unifying themes underlying students' difficulty with mutation. In this study, we examined students' written explanations about mutation from a cognitive science perspective. According to one cognitive…

This study examined the preconceived notions of preservice teachers toward those from poverty backgrounds at a medium-sized public university in Pennsylvania, USA. Results of the study indicate that cultural stereotypes about those who are poor persist in preservice teachers and that these views differ significantly based on when, how and in what…
