My dissertation research has been a quest to understand how to improve metacognition development in undergraduate chemistry education. The first step I took in this investigation was to speak with those with the largest influence on an undergraduate chemistry student's education: the instructors. I interviewed seventeen postsecondary chemistry…

Nearly half of all U.S. students who declare science majors in college do not graduate with science degrees within six years. Improvements in science outcomes are linked with active-learning pedagogies such as Course-based Undergraduate Research Experiences (CUREs). However, despite the need for education reform particularly in Alabama,…

Although many undergraduates begin college as STEM majors, attrition rates from the field are high and numerous reports suggest that evidence-based teaching methods are critical for retention. Despite educators' research and near consensus that active learning is more effective than lecture, there are many types of active learning and the…

This study explored perceptions and practices around authentic assessment within a diverse, science-based school at an Australian University. We were motivated to inquire into authentic assessment through a work-readiness lens, with the goal of embedding the assessment of skills that are transferable across a range of STEM roles and graduate roles…

As online courses become increasingly common at the college level, an ongoing concern is how to ensure academic integrity in the online environment. One area that has received particular attention is that of preventing cheating during unproctored online exams. In this study, we examine students' behavior during unproctored exams taken in an online…

We present a modernization of the undergraduate physical chemistry laboratory experiment for determining the speed of sound in various gases from resonant frequencies in a spherical resonator. The resonator (schematic IR = 7.5 cm) is constructed by 3D printing with eco-friendly poly(lactic acid), a commercially viable alternative to traditional…

Scientific reading and communication have become key components in postsecondary science education. However, undergraduates have often been found to lack motivation to engage in these tasks. The present study surveyed 2098 undergraduates and 27 biology faculty members to compare their views on the importance and time cost of eight practices in…

Although there is increased uptake of active learning approaches in especially developed countries, this is still lagging within the African context. The current study therefore focused on the implementation of group learning at Stellenbosch University, with several modifications versus our earlier, pilot study. Students freely formed small groups…

Physics education research is replete with observations and proposed explanations for gender disparities in physics. In this work, we operationalize a definition for equity as everyone has access to the learning environment and everyone's voice is heard (adapted from previous definitions). We review prior research that observed inequities in…

Using smartphones in experimental physics teaching offers many advantages in terms of engagement, pedagogy and flexibility. But it presents drawbacks such as possibly endangering the device and also facing the heterogeneity of available sensors on different smartphones. We present a low-cost alternative that preserves the advantages of…

The video of a free-falling object was analysed in Tracker in order to extract the position and time data. On the basis of these data, the velocity, gravitational potential energy, kinetic energy, and the work done by gravity were obtained. These led to a rather simultaneous validation of the conservation law of energy and the work-energy theorem.…

The capstone course for many Earth Science programs is a field course. To increase accessibility and to create a substitute in light of the cancellation of in-person courses due to the COVID-19 pandemic, we developed an online introductory field geology course. The course consisted of six different modules. The first was a virtual reality room,…

This paper describes the development of a fully remote upper-class biochemistry lab course. The sudden change to online teaching in the middle of spring semester 2020 had a primarily negative impact on laboratory teaching. These effects were mitigated because the students had done many of the basic hands-on procedures before the switch. A true…

The American Chemical Society holds supporting diverse student populations engaging in chemistry as a core value. We analyzed chemical concept inventory scores from 4,612 students across 12 institutions to determine what inequities in content knowledge existed before and after introductory college chemistry courses. We interpreted our findings…

What and how instructors assess understandably impacts student learning and performance in undergraduate science courses. However, there is limited research on the ways in which assessment practices might be altered to combat inequitable outcomes in these settings. Here we characterize the nature of assessment questions in one second-semester…
