We conducted two studies to investigate the extent to which brief, spaced, mastery practice on skills relevant to introductory physics affects student performance. The first study investigated the effect of practice of "specific" physics skills, each one relevant to only one or a few items on the course exam. This study employed a…

Undergraduate biology laboratories emphasize hands-on skills. Typically, descriptions of manual techniques are delivered via written instruction. Custom-produced prelab instructional videos, which augment prelab instruction, have come into wider use in recent years. However, institutional and economic barriers can interfere with video production…

This study explores the use of artificial intelligence in grading high-stakes physics exams, emphasizing the application of psychometric methods, particularly item response theory, to evaluate the reliability of AI-assisted grading. We examine how grading rubrics can be iteratively refined and how threshold parameters can determine when…

In a technology-enhanced learning environment and underpinned by a unique hybrid pedagogic model that borrows from gamification, constructivism, and experiential learning approaches, badges were purposefully used to foster engagement. This approach promoted the development of a mindset that identifies and appreciates the worth of a portfolio of…

ChatGPT has emerged as a popular choice in education that has transformed the experience for both teachers and students. This study investigates the performance of ChatGPT in aiding learning in the biochemistry classroom in two ways. We sought to determine how effective ChatGPT 3.5 was in generating study materials for an introductory biochemistry…

To test the hypothesis that students who complete remote online tests experience an 'online grade penalty', we compared performance outcomes of second-year students who elected to complete exams online to those who completed face-to-face, paper-based tests in an organic chemistry course. We pursued the following research questions: (RQ1) Are there…

Efforts to discourage academic misconduct in online learning environments frequently include the use of remote proctoring services. While these services are relatively commonplace in undergraduate science courses, there are open questions about students' remote assessment environments and their concerns related to remote proctoring services. Using…

This research aims to develop HOTS physics questions based on Modern Test Theory designed and presented with LMS Moodle on e-learning, which can be accessed online. This study also serves as one of the efforts to expand students' HOTS by applying a variety of HOTS-based learning sources. Further, this research employed the ADDIE model with…

Practical classes are an important and essential part of undergraduate programs in Chemical Engineering, as each experiment provides an opportunity to reinforce the theory of discrete unit operations that are taught elsewhere in the course. While an expensive pedagogical method, when practical sessions are delivered well, they can be one of the…

We investigate a personal response system (PRS) pedagogy for lecture halls that encourages active engagement yet lowers barriers for implementation by eliminating the need to address student requests to make up questions because students must answer (not necessarily correctly) only more than half (greater than or equal 50%) of PRS questions to…

Learner-centered pedagogical methods that are based on clinical application of basic science concepts through active learning and problem solving are shown to be effective for improving knowledge retention. As the clinical relevance of biochemistry is not always apparent to health-profession students, effective teaching of medical biochemistry…

To slow the spread of COVID-19, many universities have had to move to online teaching, which entails changing exams from in-person to online. Online exams can facilitate cheating when there is no direct proctoring. To provide some form of control in unproctored exams, Cluskey et al. (2011) suggested having substantial time pressure; yet there are…

During the COVID pandemic, universities around the globe had to move not only their content delivery online, but also their assessments. Due to COVID causing significant upheaval in Higher Education (HE), this enforced experiment also afforded an opportunity to reflect on traditional, invigilated, closed book exams (ICBE) resulting in research and…

This work reports a classroom experience of a general physics course designed to foster also the initiation of preservice mathematics and biology teachers to physics pedagogical content knowledge. To modify the conceptions that these students have about teaching and learning, the course was taught using different active learning instructional…

The efficacy of the various pedagogies that are used in human anatomy laboratories has been extensively debated. Nevertheless, an important question remains relatively unexamined--how the learning experience in the anatomy laboratory impacts students' mastery and application of anatomical knowledge beyond the laboratory setting. In this study, the…
