The Arduino microcontroller is currently one of the favorite tools of makers, and many teachers have used it in teaching or experiments. In addition, light-emitting diode (LED) smart lighting is the worldwide trend in lighting. There are many teaching demonstrations or applications of color addition using LEDs. Furthermore, the Internet of Things…

An experiment for the upper-level biochemistry laboratory is described in which students isolate a wild yeast from environmental sources and characterize the strain for its potential in the brewing industry. In addition to providing valuable experience in important biochemical techniques, this study also illustrates key principles of…

The aim of this study is to define epigenetic literacy and describe how it can be included in school biology. Epigenetics is a new field of research in biology with abundant societal consequences and conceptual implications on how genetics is understood. Epigenetics explains how genes are regulated, thereby clarifying cell differentiation, and…

Stereoselective reduction of ketones to alcohols using baker's yeast is a classic experiment in the undergraduate laboratory. Here we illustrate the reduction of racemic ethyl 2-fluoro-3-oxobutanoate to the corresponding alcohol using a set of four commercially available ketoreductases (KREDs). The reaction sets two stereocenters with four…

Internationally, there are calls for students to be able to use their scientific understandings to make informed decisions about the world in which they live. Using a mixed methods case study design, this study investigated the impact of behaviours and strategies used by two early career science teachers who taught argumentation about a…

In response to the global crisis of type 2 diabetes prevalence, this dissertation investigated the impact of a culturally sustaining, health-centric science curriculum contextualized in type 2 diabetes. Using a case study methodology, it explored how the curriculum shaped math and science preservice teachers' (PSTs) perceptions of science and how…

Despite reform efforts and calls to accept science as a primary subject in elementary school curriculum and instruction (NRC 2007, 2012), science is still often neglected, deprioritized, minimally taught, or taught through traditional methods where teachers and textbooks are the gatekeepers of knowledge (Banilower, 2019; Banilower et al., 2018;…

The advantage of VLs lies in their capacity for simulating real-world lab experiences within a fully immersive digital environment, yet the uptake in rural schools in developing countries remains low. To understand this paradox, this study explores the perceptions of seven secondary school science teachers in a rural district in South Africa.…

Fungi mostly reproduce through spores that are adapted for airborne dispersal; hence, fungal spores (and fungi) are found virtually everywhere. Fungi can be "friends or foes." Our friends include fungi used in the food and biotech industries, fungi that contribute to the cycling of carbon and nutrients, and those involved in the…

The past decade has been marked by a series of global crises, presenting an opportunity to reevaluate the relationship between science and politics. The biological sciences are instrumental in understanding natural phenomena and informing policy decisions. However, scholars argue that current scientific expertise often fails to account for entire…

Many technological applications (apps) purport to help children learn academic material. Building on research in developmental and educational psychology, we developed and tested an app to teach biological and physical science content to preschool children. There were 21 children in the control condition (M[subscript age] = 50.30 months, SD =…

Multilingual learners (MLs) represent an increasing proportion of public school students. Although much attention has been given to their academic performance in English language arts and math, less research has addressed their academic performance in science, particularly in elementary school. This study leveraged nationally representative data…

Previous work has identified that recognition from others is an important predictor of students' participation, persistence, and career intentions in physics. However, research has also found a gender bias in peer recognition in which student nominations of strong peers in their physics course disproportionately favor men over women. In this…

'A lack of prior knowledge in the other discipline' is often given by geoscience instructors to explain why students struggle to apply knowledge from other disciplines to the Earth. We examine this assumption by considering the disciplinary crossing of buoyancy (physics) to isostasy (geoscience). We investigate the teachers' perspective through…

The global Coronavirus disease 2019 (COVID-19) pandemic and associated restrictions on indoor gatherings posed considerable challenges to the delivery of courses that traditionally have relied on hands-on learning in their laboratory components. Here, our experiences converting a senior instrumental analysis course to remote online learning in the…
