Forward genetics involves the identification of an unknown DNA sequence (genotype) associated with the expression of that sequence (phenotype). This is often done by generating variants (mutants) of that feature. One of the most practical methods is transposon mutagenesis, which facilitates the genotype-phenotype association through a sequence…

Wave optics is a mandatory part of Croatian secondary school physics curriculum for students in the final year of secondary school (age 18-19). Many physics education research studies have shown that it is a difficult physics topic for both university and secondary school students. An inquiry-based teaching sequence on wave optics, designed for…

Recent advancements in computer graphics and hardware have driven the resurgence of virtual reality (VR). Past literature has reported the use of VR in education, especially for teaching spatially complex concepts. However, there are limited data available on the precise role of VR game design elements. In this study, we introduce a new VR game,…

The teaching competencies of science teachers significantly influence students' science academic achievement. It shapes the students' understanding of complex science concepts and their ability to excel in scientific exploration, ultimately nurturing their scientific literacy. This study assessed the teaching competencies influencing the teaching…

The literature on scientific modelling practices in science education has provided a fruitful discussion on how learners tend to view models vs. how and what they should think about them. One approach is to teach students that models are abstractions so that they do not view them as a copy of phenomena they represent. Although teaching students…

"American Biology Teacher" has published over seven dozen articles relevant to the history of biology in biology teaching. They are cataloged here and indexed by topic. As reflected in this archive, teachers adopt a historical approach for many pragmatic motivations: (1) to engage students, by contextualizing science culturally; (2) to…

Here, we propose a laboratory exercise to quickly determine single nucleotide polymorphisms (SNPs) in human "alcohol dehydrogenase 1B (ADH1B)" and "aldehyde dehydrogenase 2 (ALDH2)" genes involved in alcohol metabolism. In this exercise, two different genotyping methods based on polymerase chain reaction (PCR), namely…

The federal government and a number of nonprofit, non-governmental agencies have invested heavily in programs designed to provide research opportunities, financial support, and mentorship to undergraduates in science-related fields. These efforts are aimed at supporting students' matriculation in science majors and into science-related careers.…

Thermal cameras have shown to have utility in secondary school classrooms and undergraduate courses. In this paper, the author argues for their potential in the primary school classroom and presents a range of activities that can be undertaken with thermal cameras (or supplied images). With limited access in mind, the activities in this paper have…

This study analyzed articles from the last four years regarding how science education research is framed and discussed as qualitative research. The research question that guided this study was: "To what extent do qualitative secondary science teaching research publications reflect high-quality practices found in mainstream methodological…

Learning media is a tool that makes it easier for educators to convey material to students effectively and efficiently to improve the quality of learning. Biology subjects in the essential enzymes and cell metabolism competencies require precision and accuracy, so appropriate learning media are needed. Booklets are a medium that can make it easier…

After a time away from the classrooms and laboratories due to the global pandemic, the return to teaching activities during the semester represented a challenge to both teachers and students. Our particular situation in a Microbial Physiology course was the necessity of imparting in shorter time, laboratory practices that usually take longer. This…

In this exploratory qualitative case study, we sought to develop a better understanding of beginning teachers' (Scholars) ideas about justice-oriented science teaching. Data were collected from participants from the same secondary teacher education program with an overarching mission of social justice. The study spanned two academic years,…

A new teaching resource comprised of raw X-ray diffraction data sets from crystallography experiments has been compiled. The aim of this resource is to provide a tool with which to plug the teaching gap between crystals and chemical structures present at various levels of education, as well as providing examples for early stage researchers and…

Liquid metals are widely applied in various fields, including chemistry, catalysis, energy storage, chemical sensing, and stretchable electronics, due to their unique deformabilities. However, their behavior under a rod or ring electrode has never been analyzed. Furthermore, research on the deformation behavior of eutectic Ga--In (EGaIn), the most…
