In quantum mechanics, probability amplitudes are complex numbers and the relative phases between the terms in superposition states have measurable effects. This article describes an investigation into sophomore- and junior-level students' reasoning patterns in relating relative phases and real-world quantum phenomena. The investigation involved…

International large-scale assessments like international computer and information literacy study (ICILS) (Fraillon et al. in International Association for the Evaluation of Educational Achievement (IEA), 2015) provide important empirically-based knowledge through the proficiency scales, of what characterizes tasks at different difficulty levels,…

Practice problems and worked examples are both well-established teaching techniques. Research in math and physics suggests that having students study worked examples during their first contact with new material, instead of solving practice problems, can be beneficial to their subsequent performance, possibly due to the reduced cognitive load…

The Next Generation Science Standards (NGSS) require teachers to think very carefully about the structure of lessons, which content must be taught to allow students to achieve NGSS expectations, and how content is delivered. With the standards' focus on three-dimensional learning and the use of relevant phenomena, most teachers are urged to make…

This paper focuses on the procedure and results for analyzing text-difficulty in lower-secondary chemistry textbooks in the Czech Republic. The authors use established methodology for text-difficulty analysis by Nestler, adapted by Prucha and Pluskal by adding a second independent analyser to improve reliability. Some textbooks do not follow the…

Navigating scientific challenges, persevering through difficulties, and coping with failure are considered hallmarks of a successful scientist. However, relatively few studies investigate how undergraduate science, technology, engineering, and mathematics (STEM) students develop these skills and dispositions or how instructors can facilitate this…

Studies comparing the instructional effectiveness of dynamic versus static visualizations have produced mixed results. In this work, we investigated whether gender imbalance in the participant samples of these studies may have contributed to the mixed results. We conducted a meta-analysis of randomized experiments in which groups of students…

Purpose: The purpose of this paper is to review the issues and challenges associated with examining PhD theses in the modern, rapidly changing academic world. The PhD degree has been described as the "pinnacle of academic qualifications", but it is under threat in terms of the quality of supervision and the outcome of examinations. By…

Texting is a widespread mode of communication and libraries are experimenting with it to interact with users. This article presents the results of a study on virtual reference service. The authors seek to determine whether or not the texting service is filling a different information need than chat and email by examining the level of difficulty…

We investigate the determinants of students' misconduct at university. Using a sample of 310 surveyed students, we find that students are more likely to cheat when they have previous misconduct records, when they perceive academic integrity policy as being poorly enforced, and when they perceive that instructor tolerance toward misconduct…

Out of all the measures of cognitive load, germane load is crucial in determining one's motivation towards learning. The dynamics between the two becomes even more important when individuals are required to grasp understanding of complex content such as the one presented by math. Current stud explores the relationship between the three facets of…

Research was conducted with 10 low literate and 10 medium to high literate students at the University of Baltimore to understand how traditional literacy impacts search habits for new college freshman. Five low literate, non-student participants were included in the research as a control group for the two student populations. It was hypothesized…

Although the presentation of extraneous (i.e., irrelevant or unnecessary) information hinders learning, it is unclear whether and how layout and pacing influence this effect. In two experiments, participants learned how the heart functions using four different layouts: a diagram presented without unnecessary text (diagram only), with unnecessary…

This study explored the impact of homogeneity of answer choices on item difficulty and discrimination. Twenty-two matched pairs of elementary and secondary mathematics items were administered to randomly equivalent samples of students. Each item pair comparison was treated as a separate study with the set of effect sizes analyzed using…

In face-to-face interviews, accurate work by interviewers is crucial for ensuring high-quality survey data. In a field experiment, payment of interviewers, legitimation of falsification behavior, and respondents' willingness to participate were experimentally varied. The impact of these factors on interviewers' accuracy during fieldwork was…
