Scientific knowledge is advanced because scientists manage uncertainty. Although managing uncertainty is an essential practice of science, transferring it from expert settings to K-12 classrooms is problematic because, understandably, students are not familiar with the intentions of scientists. Few studies have explored learning science as an…

This study describes outcomes from a place-based, teacher-scientist partnership intended to support teacher use of authentic data for science and math instruction. Teachers worked with scientists in the field to practice collection and analysis of authentic data. This case study investigated how narrative structure and contextualisation were…

This paper explores the ways learners respond to and express themselves while interacting with cultural artifacts or cultural realia, "beads and beadwork," used to mediate the teaching and learning of life science concepts in a science classroom. South African policies, enacted in the National Curriculum Statement (NCS) and the…

This study describes the use of worksheet activities based on alternative concepts from a two-tiered diagnostic assessment on chemical phenomena to remediate 37 first year non-major chemistry pre-service teachers' alternative conceptions about word chemical equations. The instruments for data collection were tiered assessments and group learning…

This meta-analysis synthesized research on gender gap in the Force Concept Inventory (FCI). The main goal of the present meta-analysis was to identify the moderator variables that mediate effect size differences. Furthermore, the statistical significance of the average effect sizes was investigated. The inclusion criteria for the meta-analysis…

How does STEM knowledge learned in school change students' brains? Using fMRI, we presented photographs of real-world structures to engineering students with classroom-based knowledge and hands-on lab experience, examining how their brain activity differentiated them from their "novice" peers not pursuing engineering degrees. A…

Problem-based learning encourages students to deepen their understanding of a concept by working through a real-world example of course content. Case studies represent a form of problem-based learning that engages students in realistic scenarios to achieve a deeper understanding of concepts. Case studies have been shown to facilitate the learning…

The authors adapted a lab-in-the-field experiment emulating the dynamic extraction of a fishery to create a Web-based classroom experiment. The game includes a multi-player version analogous to an open-access problem and a single-player version analogous to the social planner problem. This game is helpful in introductory microeconomics courses to…

Physics education aims to develop sophisticated thinking abilities and enhance conceptual depth, but student interest has decreased, emphasizing the importance of teacher quality in fostering success and positive attitudes. The aim of the study was to examine the physics teachers' self-efficacy, innovative teaching, and comprehensive teaching…

Learning about components and processes of complex biological systems is challenging and requires abstraction through mediational tools such as text, visuals, models and visualisation experiences. The 'systems concepts' necessitate building coherent relations and anticipating consequences, requiring greater mediational support. This article…

In Cell Biology, a sophomore/junior undergraduate-level high-enrollment core course, students areexpected to develop a broad and detailed understanding of the functioning of eukaryotic cells. Forexample, some of the more challenging biological concepts include machinery involved in thereplication and translational processes, protein…

The purpose of this exploratory study was to investigate Brazilian school teacher attitudes and approaches to biodiversity education. We aim to specifically compare the amount of native biodiversity topics as measured by teachers' reports of their teaching emphasis. The study involved 147 teachers from all geographic regions of the country, who…

The COVID-19 outbreak has had a significant impact on higher education worldwide. In-person courses had to be quickly transited to online, including lab courses embedded with Course-based Undergraduate Research Experiences (CUREs). In response to this challenge, we successfully converted a fully in-person biochemistry lab that integrated with a…

The phenomenon of lateral inversion is explored in this question. If a clock is viewed in a plane mirror, will the motion be clockwise or anticlockwise?

Most students find real-world examples of harmonic oscillations interesting. Besides, normal and friction forces are the types of concepts in physics that are readily applicable to their everyday life. For instance, we depend on these forces to write, to drive cars, to pick up objects, and even to walk! And yet introductory physics students have…
