When students think of evolution, they might imagine T. rex, or perhaps an abiotic scene of sizzling electrical storms and harsh reducing atmospheres, an Earth that looks like a lunar landscape. Natural selection automatically elicits responses that include "survival of the fittest," and "descent with modification," and with…

We describe the components and implementation of an activity for multivariable calculus featuring applications to the field of chemistry. This activity focuses on the isobaric thermal expansion coefficient found using partial differentiation of the volume of an ideal gas with respect to temperature as pressure is held constant. Broader goals of…

Many science students struggle with using scientific language and making sense of scientific phenomena. Thus, there is an increased interest in science education research and public policy with regard to understanding and promoting scientific language use and sensemaking in science classrooms. However, there is a lack of comparative studies on how…

Genetics concepts is taught at secondary school to equip students with relevant knowledge to engage with related socio-scientific issues in order to make a reasonable decision. However, earlier research shown that students exhibited poor comprehension of this concept. Despite several interventions, this problem persists. This study was designed to…

The most famous equation in physics, E = mc[superscript 2], is rarely introduced in middle school physics curricula. Recent research has shown that teaching Einsteinian concepts at the middle school level is feasible and beneficial. This paper analyses an Einsteinian energy teaching module for Year 8 students (13-14 years old), which encompasses…

The COVID-19 pandemic necessitated changes in educational strategy, including modification of assessments. Students in the Master of Biomedical Sciences (MBS) program at Duke University School of Medicine are required to take a course entitled "Organ Systems" (OS), which includes organ histology. In pre-pandemic circumstances, cumulative…

Electron transport chain and oxidative phosphorylation are always a challenging topic for students studying metabolism. We had adopted blended learning in metabolism teaching and evaluated the learning experiences of students. In this project, a pre-class learning aid the "Story Mode" and a post-class learning aid the "Revision…

Learning to plan modeling-based investigations (MBIs) presents significant challenges for pre-service elementary teachers. Although they understand disciplinary core ideas and modeling practices, they address both as competing learning goals and, as novices, they have not experienced how to structure MBIs for their future students. In the context…

Health literacy should be developed from early ages, but students, including preservice teachers, hold misconceptions about micro-organisms. The objective of this study was to analyse the knowledge that a sample of 102 Early Childhood Preservice Teachers (PST) had about micro-organisms and about cystitis. The PSTs performed a series of activities…

Short chain fatty acids (SCFAs) are produced in the gut as a result of microbial action on ingested dietary fiber and have been associated with several health benefits. Herein an undergraduate student experiment that uses gas chromatography equipped with either a flame ionization detector or mass spectrometer for the analysis and quantitation of…

Lakes are artists' pigments made from colorants bound to an inert substrate, usually hydrated aluminum oxide. Before the late 19th century, lakes were made from natural pigments extracted from plants and insects, extracted either directly from the dyestuff or indirectly from waste materials generated in the manufacture of dyed textiles. The first…

Despite considerable progress made in educational neuroscience, neuromyths persist in the teaching profession, hampering translational endeavors. The initial wave of interventions designed to dispel educational neuromyths was predominantly directed at preservice teachers. More recent work in the field, reviewed here, has shifted its focus…

We use the Survey of Thermodynamic Processes and First and Second Laws-Long (STPFaSL-Long), a research-based survey instrument with 78 items at the level of introductory physics, to investigate introductory and advanced students' difficulties with entropy and the second law of thermodynamics. We present an analysis of data from 12 different…

A large body of research literature has explored socio-scientific issues (SSIs) in science teaching and learning, documenting the impact of epistemic beliefs on epistemic emotion, which influences student's reactions to complex scientific topics. Often, students' reactions reflect scientific misconceptions, the correction of which may result in…

Observational practice is discussed as a substitute for physical practice for motor learning and adaptation. We systematically reviewed the literature on observational practice in reaching and aiming tasks. Our objectives were to identify (i) performance differences between observational and physical practice; (ii) factors that contribute to…
