Physics graduate teaching assistants (GTAs) are tasked with multifaceted teaching assignments, such as leading tutorials and inquiry-based laboratories, yet their professional development rarely includes opportunities to rehearse complex pedagogical skills or receive feedback on their teaching. In this study, physics GTAs practiced specific…

The purpose of this mixed-method action research study was to improve Black students' performance in my sixth-grade science class by improving their ability to use the claim, evidence, and reasoning (CER) framework. Using criterion-based convenient sampling, I enlisted 17 Black participants, all of whom were underperforming in my science class at…

The aim of the study is to examine informational children's picture books prepared for preschool children in terms of scientific process skills. The study was conducted using the document review method, one of the qualitative research methods, and descriptive analysis method was used in the analysis of the data. Within the scope of the research,…

Although much research exists of students' alternative conceptions about evolution and natural selection, the way in which these vary in time and how scientific explanations change during instruction remains to be described and understood. Therefore, the main objective of this research is to characterise the nature of the change in student…

Introduction: This study aimed to estimate the causal effect of face-to-face learning on student performance in anatomy, compared to online learning, by analysing examination marks under a causal structure. Methods: We specified a causal graph to indicate how the mode of learning affected student performance. We sampled purposively to obtain…

This report describes a laboratory experiment for an undergraduate-level inorganic chemistry or biochemistry course involving the study of the kinetics of the catecholase activity of a synthetic nickel­(II)-oximate complex. A model substrate, 3,5-di-tert-butylcatechol(DBC), undergoes aerobic oxidation to 3,5-di-tert-butylbenzoquinone (DBQ) in the…

This article reports the development of a dissemination work and analysis of the influence of a chemistry science dissemination video on the perception of university students in relation to scientific research carried out at the public university, to scientific dissemination itself and the use of scientific dissemination videos as learning tools.…

This article reports the development of Chem'Sc@pe, an escape game activity for first- and second-year undergraduate students, covering various topics from an introductory organic chemistry course. The objective was to encourage them to review notions learned in class in a fun and collaborative environment. The set comprises a game board…

Different molecular representations are usually used to depict the three-dimensional (3D) structure of organic compounds. Mastering the skill of interconverting one form into another is essential for students to ensure success in organic chemistry. The traditional and recently developed methods for completing such interconversions that rely on 3D…

Teaching green chemistry within the K-12 classroom has a positive impact on attitudes and perceptions of chemistry in society for future scientists and professionals, resulting in safer, less hazardous chemistry experiments and demonstrations. The state of New York has taken advantage of the benefits that green chemistry provide in the classroom…

Poinsettia ("Euphorbia pulcherrima") contains anthocyanins that dissolve in water and exhibit color changes due to changing pH. This property makes the poinsettia extract a useful acid-base indicator for pH demonstrations. When combined with common household materials, this experiment can be used as an alternative low-cost tool in…

Online conferencing platforms such as Zoom and Microsoft Teams have been widely adopted as substitutes for physical classes during the COVID-19 pandemic. This dramatic change is accompanied by many challenges for educators to keep their students engaged online and promote live interactions to mimic a real classroom environment. While progress has…

An increased reliance on nanotechnology and recent developments in materials fabrication coincide with a greater prevalence of 3D printers in high schools. We developed this lesson to foster an exploration of interdisciplinary fields and to increase access to recent advances in materials chemistry through two different learning modules. The lab…

MóviLab (Moving Lab) was an educational strategy developed at Universidad Industrial de Santander, Colombia, to promote chemistry and science among schoolchildren and teenagers from far rural areas of the Santurbán moor in Colombia during the COVID-19 pandemic. The strategy consisted of designing a kit with chemistry experiments that could be done…

The current work develops intelligent tutoring aspects for the DiscoverOChem learning platform. Intelligent tutoring systems are technology-based learning systems that can adapt the learning experience to better serve individual users. DiscoverOChem (www.discoverochem.com) is a free Internet-based platform for learning undergraduate-level organic…
