Navigating the observational, symbolic, and theoretical knowledge domains of chemistry is crucial for chemistry sensemaking. However, this has been shown to be particularly challenging for students of chemistry. In order to reach government standards for sensemaking in the chemistry subject, it is important to investigate how chemistry teachers…

With the already widespread nature of multiple-choice assessments and the increasing popularity of answer-until-correct, it is important to have methods available for exploring the validity of these types of assessments as they are developed. This work analyzes a 20-question multiple choice assessment covering introductory undergraduate chemistry…

Teachers' teaching practices are influenced by various factors, including the teacher's personal (e.g. beliefs, efficacy and attitudes) and school context (e.g. administrative and collegial support). However, the previous model did not consider the interactions between these factors simultaneously in effecting the teaching practices. Thus, an…

Genetics concepts is taught at secondary school to equip students with relevant knowledge to engage with related socio-scientific issues in order to make a reasonable decision. However, earlier research shown that students exhibited poor comprehension of this concept. Despite several interventions, this problem persists. This study was designed to…

In educational research, there is the general trade-off that empirical evidence should be generalizable to be applicable across contexts; at the same time, empirical evidence should be as specific as possible to be localizable in subject-specific educational interventions to successfully transfer the empirical evidence to educational practice.…

The most famous equation in physics, E = mc[superscript 2], is rarely introduced in middle school physics curricula. Recent research has shown that teaching Einsteinian concepts at the middle school level is feasible and beneficial. This paper analyses an Einsteinian energy teaching module for Year 8 students (13-14 years old), which encompasses…

Gamifying is related to the motivational gain and engagement of participants in these systems, even in situations not exclusively related to the creative and entertainment industry. In the Biology teaching context, motivational strategies have fundamental importance to the learning process. The aim of this work was to investigate the development…

Electron transport chain and oxidative phosphorylation are always a challenging topic for students studying metabolism. We had adopted blended learning in metabolism teaching and evaluated the learning experiences of students. In this project, a pre-class learning aid the "Story Mode" and a post-class learning aid the "Revision…

Play is crucial to children's development. With the prevalent use of digital technologies, children and young adults are seen playing games more often and longer on digital devices. How should teachers capitalize the advantages of games in class, without inducing more health risks or problems for children? To achieve this goal, teachers need…

Learning to plan modeling-based investigations (MBIs) presents significant challenges for pre-service elementary teachers. Although they understand disciplinary core ideas and modeling practices, they address both as competing learning goals and, as novices, they have not experienced how to structure MBIs for their future students. In the context…

Teachers' reflections on their practice are a powerful tool for measuring and supporting their professional knowledge. Pedagogical content knowledge is one of the most influential domains of teacher professional knowledge. This multiple-case study investigated the topic-specific pedagogical content knowledge (TSPCK) components that Zambian…

Simulation-based teaching can be a valuable method for learning statistical concepts. Its practical implementation for health-related subjects is seldomly evaluated. We propose a simulation-based approach to teach interaction effects in a postgraduate biostatistics course. We describe the steps involved in organizing and implementing a…

This is a study intended to address white supremacy in science education. To accomplish this, we describe how one White intern, Boaz, learned to teach science in anti-racist ways. By detailing how whiteness mattered in his learning to teach, we demonstrate that whiteness is potentially constant in White peoples' learning to teach science in…

Mixed results have been reported on the correlation between clickers and performance. This study investigates the usage of clickers in a voluntary context to answer in-class questions in a General Chemistry class. Scores on an internal chemistry placement exam were used to estimate cognitive ability, as a factor that students can no longer…

Short chain fatty acids (SCFAs) are produced in the gut as a result of microbial action on ingested dietary fiber and have been associated with several health benefits. Herein an undergraduate student experiment that uses gas chromatography equipped with either a flame ionization detector or mass spectrometer for the analysis and quantitation of…
