Background: The coherence of learners' pre-instruction conceptions has been debated for some time. Studies on conceptions of force, specifically, have produced very different results in different contexts around the world. In this study, an integrative theoretical framework linking semantic differences across languages to concept learning in…

In the collectivistic Thai society, oppressions are considered societal taboos that teachers rarely talk about in schools despite many oppressive events that happened in the past few decades (e.g., the 1976 student massacre and other political unrests). Science education in Thailand heavily emphasizes technical knowledge and rote memorization --…

While uncertainty is inherent to doing science, it is often excluded from science instruction, especially postsecondary chemistry instruction. There are a variety of barriers to infusing uncertainty into the postsecondary chemistry classroom, including ensuring "productive" struggle with uncertainty, evaluating student engagement with…

Explicit teaching of metacognition, 'thinking about one's thinking,' has been shown to improve achievement scores in the general chemistry tests and facilitate the awareness and adoption of metacognitive strategies. However, very few studies have investigated variations in the reported metacognitive strategies employed by college science majors by…

Internationally, second level curriculum policy for STEM education is concentrating its efforts on promoting curriculum-making pedagogies, with enquiry-based teaching and learning at the forefront of this change. Policy aspirations have not translated well into practice, evidenced by science practical lessons consistently being delivered as…

The purposes of this study were to explore how a science teacher and a mathematics teacher collaborated for science and mathematics integration with the support of a researcher, to describe the process of planning and implementing integration and to understand the main issues considered by teachers during the process. Observational case study was…

Molecules and Computer: Chemistry Calculations in Class (MC[superscript 4]) is a computational laboratory intended for final-year high school or undergraduate students. The topic is the antioxidant potential of anthocyanidins, which is chemically related to their radical scavenging action via the mechanism of hydrogen atom transfer (HAT). This…

The purpose of this article is to describe the possibilities of using worksheets in the teaching of lipids and proteins. The worksheet includes a concept map, suggestions for three safe experiments that can be performed with available household chemicals, and observation results. The worksheets were implemented into action research in two classes…

Hands-on chemistry experiments often stimulate students' curiosity about this subject, but blind or visually impaired (BVI) students usually do not get to participate in such hands-on activities. Thanks to adaptive methods and assisting technology, BVI students can actively participate in chemistry experiments. In this study, chemical laboratory…

In education, space exists for a tool that valorizes generic student course evaluation formats by organizing and recapitulating students' views on the pedagogical practices to which they are exposed. Often, student opinions about a course are gathered using a general comment section that does not solicit feedback concerning specific course…

Cryogenic electron microscopy (cryo-EM) is a powerful technique capable of characterizing large protein complexes that are otherwise impossible to characterize using traditional crystallography methods. Cryo-EM has played a pivotal role in our understanding of the structure--function relationship of the spike proteins on the COVID-19 viral…

A community-engaged learning experiment was developed for an introductory analytical chemistry course at the University of Toronto Scarborough in collaboration with Campus Farm. The experiment introduced students to the application of analytical techniques to studying environmental samples. More specifically, students investigated the potential of…

Experiments involving electrochemical cells are of great pedagogical value for learners of introductory chemistry. This paper discusses an improved experimental kit made from a 24-well cell culture plate and a 3D-printed scaffold. The current design focuses not only on the accuracy of the result but also on the intuitiveness of the wiring work and…

The complexity of science visual literacy education calls for a better understanding of elementary teacher visual literacy practices. Teachers play a key role in developing students' visual fluency through the visual literacy skills they develop in their pedagogical practices. Addressing these gaps in the research, this dissertation focused on the…

The structure and function relationship is a core concept identified by physiology faculty. Prior research has shown this may be a difficult concept for students to understand. Formative written assessments, such as short answer essay questions, allow students to demonstrate their thinking by encouraging students to use their diverse ideas to…
