Preservice elementary teachers are faced with the daunting task of learning enough about every subject to support their students' development of foundational ideas. Teacher preparation programs and professional development providers therefore have the challenge of supporting those preservice and in-service teachers by providing content and methods…

The methodology and mathematical treatment of several classic multivariate methods for the analysis of spectroscopic data is demonstrated in a straightforward way that can be used as a basis for teaching an undergraduate introductory course on chemometric analysis. The multivariate techniques of classical least-squares (CLS), principal component…

Green chemistry and chemical safety complement each other in reducing adverse health and safety outcomes. However, it is imperative to train students of advanced synthetic chemistry, beyond reaction mechanisms, to proactively connect complex experiments with hazard analysis, risk minimization, and planetary sustainability. Virtual experiments…

The paper describes guidelines for the planning, organization, and implementation of virtual activities within a metaverse environment, aiming to familiarize students with key concepts related to hard and soft acids and bases (HSAB) theory. The guidelines are based on experience gained during an online lesson given in January of 2022 for 188…

We investigated the effects of in-game learning supports' timing in a game called Physics Playground where we randomly assigned 149 students (M[subscript age] = 14, SD = 0.96) to receive learning supports either Before (n = 50) or After (n = 46) playing game levels--a no-support Control (n = 53) condition was included. We found that students…

Knowing about the evolution of atomic models throughout history is a fundamental topic to learn about atomic structure. This paper describes how identifying keywords from a musical YouTube video provides a stimulating activity for learning this topic in a chemistry class in middle school. The main goal was to show how a fun and interesting…

Chemistry students are passionate about using their learning to contribute toward a sustainable future, yet they feel unprepared to make green and sustainable practical decisions informed by industry-relevant tools. Most green chemistry metrics are mass-based, which do not estimate environmental impact or help address global socioeconomic…

Course-based undergraduate research experiences (CUREs) are being increasingly implemented to broaden the opportunities for undergraduate students to engage in authentic research across STEM disciplines including chemistry. The present review synthesizes the literature on chemistry CUREs, encompassing 68 articles published between 2016 and 2022…

Engineering projects, such as designing a solar farm that converts solar radiation shined on the Earth into electricity, engage students in addressing real-world challenges by learning and applying geoscience knowledge. To improve their designs, students benefit from frequent and informative feedback as they iterate. However, teacher attention may…

To advance ongoing efforts to diversify the healthcare field and promote inclusion in physiology education, the present study investigates the potential for an evidence-based intervention, Scientist Spotlight assignments, to highlight counterstereotypical representations of scientists in the context of majors and nonmajors physiology courses.…

Medical students must be adept at critical thinking to successfully meet the learning objectives of their preclinical coursework. To encourage student success on assessments, the course director of a first-year medical physiology course emphasized the use of learning objectives that were explicitly aligned with formative assessments in class. The…

This study aims to examine how five-year-old children demonstrate their learning through mathematical games in preschool settings in Palestine. It also explored the perspectives of children and teachers of different stages of play. The sample consisted of 90 children and 6 teachers. Children were guided to a wide range of mathematical games.…

This article examines the impact of a professional development program aimed at encouraging high school teachers to include more modern physics in their enacted classroom curricula through improved content and pedagogical knowledge. The program was implemented with 17 high school physics teachers (three were the focal point of this study) in…

In common with many other countries, the Iranian science curriculum does not introduce primary children to atoms and molecules but instead leaves the teaching of these concepts until high school. This paper challenges this practice and describes the changes in elementary Iranian children's understanding of atoms and molecules following a 10-h…

This study presents an analysis of the incommensurability about the representations or models elaborated by children from an Indigenous community within three areas or cultural domains, namely, the ethnic, daily (domestic), and school domains and their implications in relation to science education. The children belong to an Indigenous Nahuatl…
