The current study aims to contribute to the literature on how organic chemistry students weigh various factors when predicting products of substitution and elimination reactions. This study focuses specifically on these mechanism types, as they are often the first instances where students must consider the "how" and the "why"…

This study investigates if a force-based teaching approach, based on quantum mechanical principles and developed in a lesson study, would enhance the understanding of chemical bonding among upper secondary school students. The teaching approach was based on research on the teaching and learning of chemical bonding. The study included first-year…

Many undergraduate chemistry students hold alternate conceptions related to resonance--an important and fundamental topic of organic chemistry. To help address these alternate conceptions, an organic chemistry instructor could administer the resonance concept inventory (RCI), which is a multiple-choice assessment that was designed to identify…

Despite the intrinsic interdisciplinary nature of STEM, teaching interdisciplinarity in the classroom is difficult and students struggle to find the applicability of concepts and skills in different scientific disciplines. In this work we propose a micro-credential "badge" system called Demonstrated Understanding of Core Knowledge (DUCK)…

Molecular Cell Biology (MCB) should be taught according to the scientific practices, avoiding cumulative and memory knowledge construction, but favoring scientific thinking. A way to achieve this goal is to apply activities involving scientific news, which construct knowledge through significant learning and the development of critical thinking.…

Knowledge of science content and the ability to translate knowledge into effective teaching is known as teachers' "content knowledge for teaching" (CKT). Teachers with developed CKT are able to more effectively determine instructional and assessment activities that will deepen K-12 students' scientific literacy. However, preservice…

The initial learning experience is a critical opportunity to support conceptual understanding of abstract STEM concepts. Although hands-on activities and physical three-dimensional models are beneficial, they are seldom utilized and are replaced increasingly by digital simulations and laboratory exercises presented on touchscreen tablet computers.…

Course-based undergraduate research experiences (CUREs) provide students with valuable opportunities to engage in research in a classroom setting, expanding access to research opportunities for undergraduates, fostering inclusive research and learning environments, and bridging the gap between the research and education communities. While…

This paper aims to investigate the systematic use of an inquiry-based learning approach in science by using inquiry boxes for preschool children. We prepared four thematic inquiry boxes for the areas of magnetism and buoyancy, separation of substances, weighing objects, and the investigation of substances. The research sample consisted of twenty…

Despite the recognized link between scientific reasoning, mental sets, and conceptual change, the cognitive mechanisms underlying successful conceptual change remain unclear. To explore this, we developed computer-based reasoning programs with and without mental set support to examine their effects on conceptual change in tasks of varying…

Glycosylation is a biologically significant post-translational modification (PTM) of proteins that involves the covalent attachment of a sugar molecule (a glycan) to a peptide sequence, resulting in the formation of glycoproteins. Glycomics and glycoproteomics involve the complete mapping of glycans of a cell, tissue, or organism.…

This study investigates the cognitive processes of novice students in science learning, with a specific focus on how inhibitory control is employed to overcome a common student misconception about the buoyant force in liquid, which leads to the belief that "the greater the depth an object is in a liquid, the greater the buoyant force it…

The year 2019 was proclaimed the year of astronomy literacy by the European Astronomical Union (EAU). Several countries around the world have now started to focus more on space and astronomy endeavours and have shaped their curriculum as a result. Therefore, the perceptions and views of secondary school pupils taking social studies courses on…

This study analyzes the effect of different instructions on threshold concepts within material covering natural selection on students' use of concepts about evolution. Moreover, it examines students' use of concepts as interconnected networks when reasoning about natural selection and analyzes how these concepts relate to each other regarding…

The rapid shift to remote instruction during the COVID-19 pandemic required widespread adoption of synchronous virtual modalities such as Zoom in higher education. This study directly compares student conceptual learning outcomes in two parallel sections of an introductory physics course--one taught face-to-face (F2F) and the other synchronously…
