Many undergraduate chemistry students struggle to understand the concept of stereoisomers, molecules that have the same molecular formula and sequence of bonded atoms but are different in how their atoms are oriented in space. Our goal in this study is to improve stereoisomer instruction by getting participants actively involved in the lesson.…

A socio-scientific issue is one of the learning techniques used today, which uses various scientific sources to make students think scientifically to conduct a dialogue and discuss solving a problem. Various problems in socio-scientific are controversial, requiring reasoning, and ethical evaluation in the decision-making process. A conflict…

Intermolecular forces (IMFs), or more broadly, noncovalent interactions either within or between molecules, are central to an understanding of a wide range of chemical and biological phenomena. In this study, we present a multiyear, multi-institutional, longitudinal comparison of how students enrolled in traditional general chemistry courses and…

This inquiry-based experiment is designed for organic or biochemistry undergraduate students to deduce the identity of phospholipids extracted from chicken eggs and dietary supplements. This is achieved using thin-layer chromatography (TLC) data, a series of guided questions of increasing complexity, and provided relative retention factor (Rf)…

Winston Churchill once said of Russia that it was a riddle wrapped in mystery inside an enigma. Were the British Bulldog a physicist, he might have been talking of something other than our Slavic comrades. He might have been talking about an electron. This article covers the more modern representations of the electron. A brief reminder of the…

The problem of ore-processing plants' waste and man-made mineral formations (MMF) disposal is very important for the Republic of Kazakhstan. The research of various ore types (gold, polymetallic, iron-bearing) MMF from a number of Kazakhstan's deposits using a complex physical and chemical methods showed, that the waste's main components are…

Although saliva has commonly been used to teach about digestion by organisms, the phenomenon of digestion is actually caused by enzymes as catalytic substances. This activity explores the hydrolysis of starch by "a"-amylase in cleaning materials as well as a comparison with the similar reaction using human saliva. The fact that the…

We describe two established STEM camps that went virtual following the outbreak of COVID-19 during the summer of 2020. Our Summer Research Opportunity (SRO) camp engages middle school science fair winners in a forensic research opportunity, while The Immokalee Foundation (TIF) camp introduces middle school students from historically…

In Malta, most science teachers are likely to have a teaching degree level qualification in one science subject. When teaching science in the first two years of secondary school they will be teaching outside their area of science specialism, that is teaching a subject/s that was not studied at degree or Advanced level. A study was conducted to…

Given the big gap between rural areas and cities and developed areas of China in basic education, it is of great significance to train a large number of excellent teachers for basic education in the vast rural areas so as to boost basic education there and achieve educational equity. Hanshan Normal University is a regional normal university…

Pedagogies of engagement (i.e., Peer-Led Teaming Learning, Problem-Based Learning, and Process-Oriented Guided Inquiry Learning) are active learning approaches used in postsecondary chemistry courses. In this study, we use data from a national survey of postsecondary chemistry instructors in the United States to estimate use of three pedagogies in…

This article presents results from a Scholarships in STEM (S-STEM) grant from the National Science Foundation that supported students from three majors and funded the development of cocurricular activities designed to increase the workforce development of first-generation and underrepresented students. Scholar cohorts were interdisciplinary, with…

Physics program for girls (PPG) is a two-week program held every summer since 2006, with the goal of engaging young women in inquiry-based physics experiments and to connect them with female science, technology, engineering, and mathematics professional role models. The program recruits young women to participate the summer after they have taken…

Here we share results from a larger study of professional development (PD) provided to faculty at Research I Urban University (RIUU), where STEM faculty modeled active learning strategies and provided ready-to-use STEM materials to teaching staff. Data from 94 STEM faculty, who comprised 27% of the total participants (N = 340), demonstrated a…

In the wake of the coronavirus disease 2019 (COVID-19) pandemic, staff and students at universities worldwide were forced to swiftly adapt to distance learning in order to continue with tertiary education. One of the main challenges we encountered during this period was a marked disconnect between staff and students, leading to lower motivation…
