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…

A novel teaching approach is aimed at elucidating the concept of bond enthalpy for general chemistry students. Through the integration of a hands-on candy pulling activity, students in a large lecture class were provided a tangible experience to explore bond strengths using rope candy and a luggage scale. Feedback from students indicated a clear…

It has become increasingly important for microbiology educators to help students learn critical concepts of the discipline. This is particularly true in virology, where current challenges include increasing rates of vaccine hesitancy, misinformation about the COVID-19 pandemic, and controversy surrounding research on pathogens with pandemic…

Herein we describe an accessible and safe at-home experiment to separate lycopene from tomatoes via liquid-liquid extraction. As a qualitative experiment, it is a canonically elementary instance for high school students to digest the conception of miscibility, immiscibility, and density difference of the two solvents. This experiment was performed…

Introduction: The replication crisis in the behavioral and social sciences spawned a credibility revolution, calling for new open science research practices that ensure greater transparency, including preregistrations, open data and code, and open access. Statement of the Problem: Replications of published research are an important element in this…

This study aims to examine preschool teachers' earth and space science practices and the expected achievements of children in these practices. The research was conducted with a phenomenological pattern. Participants of the study consisted of 28 preschool teachers working in public schools and determined by the criterion sampling method, one of the…

In this paper, we present a concise and technique-heavy route to the synthesis of dimedone for a second-year organic chemistry curriculum. Our preparation of dimedone guides students through a Michael addition followed by a Dieckmann cyclization, basic ester hydrolysis, and thermal decarboxylation, while allowing time for mechanistic discussion…
