Insufficient knowledge of chemical hazards can cause unsafe behaviors, diseases, and accidents in the laboratory, hence educational interventions are significant. Due to its unique qualities, distance learning via educational applications has grown dramatically. This study aimed to determine the efficacy of a safety training intervention via…

This laboratory exercise integrates chemistry and biology concepts to give third/fourth-year undergraduate students an opportunity to apply knowledge from different subject areas to address a real-world biomedical issue such as pathogen inhibition using composite materials. It involves the preparation of a bacteria-derived cellulosic biopolymer…

The COVID-19 pandemic has significantly affected teaching processes worldwide, particularly in laboratory-intensive courses. To adapt, online experiments have been implemented globally. In response, educators at the Department of Chemistry, Chulalongkorn University, developed a Lab@Home chemistry experiment for their general chemistry lab course…

Supplemental instruction (SI) confers student success, as represented by grades, knowledge retention, and student engagement. However, studies often report professional, not undergraduate, program findings. To measure these effects, students studying human anatomy at a university in Ontario, Canada, attended structured (peer-assisted) or…

The advantage of VLs lies in their capacity for simulating real-world lab experiences within a fully immersive digital environment, yet the uptake in rural schools in developing countries remains low. To understand this paradox, this study explores the perceptions of seven secondary school science teachers in a rural district in South Africa.…

Despite attempts to diversify healthcare workplaces and education, racial and ethnic minorities (REM) remain underrepresented in these fields. This study investigated changes in high school students' health science interest following a single exposure, hands-on anatomy laboratory visit. One hundred and eighty-eight high school students…

Course-based undergraduate research experiences (CUREs) have been proposed as a mechanism to democratize access to the benefits of apprentice-style scientific research to a broader diversity of students, promoting inclusivity and increasing student success and retention. As we evaluate CUREs, it is essential to explore their effectiveness within…

Grades matter to students, and grading methods have documented impacts on student outcomes. While many strategies exist to study variance and reliability in research settings, unique challenges exist when it comes to applying these techniques in practical settings of post-secondary coursework. In our course setting, teaching assistants (TA's)…

Hands-on experiments and teacher-based demonstrations are two standard teaching methods in secondary school when teaching chemistry in the laboratory. The available literature on these two teaching methods focuses on students' academic achievement. Most of this literature reports inconsistent results, and few studies examined teachers' and…

This study aims to assess the effect of experiential learning coupled with thinking-based learning (TBL) pedagogy in developing higher-order thinking skills. We utilized OLabs, a virtual lab, as a mode of experiential electronic-learning for the topic "chemical reactions." Online experimental activities, embedded with thinking-based…

A key part of the practice of chemistry is the analysis of chemical composition, including through gravimetric analysis and spectrophotometry. However, the complexity of doing multiple calculations to obtain analytical evidence, such as that required to determine an empirical formula, presents a challenge if such analytical methods are to be…

Health-related career goals are popular among high school science students, yet few understand the application of chemistry and biology research to the field of medicine and its impact on society. In this five-day multidisciplinary summer camp, high school students learn about the real-world relevance of medicinal chemistry research and its…

The global Coronavirus disease 2019 (COVID-19) pandemic and associated restrictions on indoor gatherings posed considerable challenges to the delivery of courses that traditionally have relied on hands-on learning in their laboratory components. Here, our experiences converting a senior instrumental analysis course to remote online learning in the…

An experiment to match five white solids with ascorbic acid, citric acid, potassium hydroxide, sodium chloride, and urea is reported here. This 4 h experiment is an integrated practice of two experimental techniques, calorimetry and titration. Students conduct an extensive literature search on the properties of the five compounds and plan the…

RC circuits are ubiquitous. They are the most common entities in modern electronics; introductory physics courses typically include a chapter and a lab on RC circuits. Several papers dealing with many aspects of RC circuits have been published in "The Physics Teacher" and other educational journals. An RC circuit contains a series…
