Clearly defining and clarifying crosscutting concepts (CCCs) helps students to apply them as thinking tools or lenses to understand disciplinary core ideas and science and engineering practices. This study identified three characteristics of the sub-concepts of CCCs: conceptual, superordinate, and common across disciplines, and explored a way…

Literacy skills are essential if students are to access knowledge and achieve academic success in middle school science. A key difficulty with interpreting literacy practices in any discipline is the problem of conceptualising what constitutes literacy. Our study contributes new understandings to the discipline of science where there are ongoing…

This study investigated meaning-making of arrows in a representation of the greenhouse effect among 14-year-old secondary school students. Data was generated during Biology lessons where 74 students discussed how they interpreted a representation from the Swedish Society for Nature Conservation, which is an NGO that produce school material. The…

Biological interactions and associations underlie life's processes at every level of organization. Here, we present a classroom activity that allows students to visualize and understand the connections within almost any biological system, from cell functions to ecological relationships. We recommend that instructors implement this activity to…

Anatomy is an essential component of clinical anesthesiology. The use of simulated patients and alternative materials, including embalmed human bodies, have become increasingly common during resident physician training due to the deemphasis on anatomical education during undergraduate medical training. In this report, the need for a more extensive…

Recent research has indicated that the utilization of digital technologies among Nepal's secondary school teachers is minimal. A multiple case study research design was employed to explore how Physics teachers at the secondary level utilized digital technologies for teaching Physics and the challenges they encountered in adopting new instructional…

How anthropomorphic reasoning functions in scientific thinking has been a controversial topic. There is evidence it is problematic as well as evidence it can play productive roles, for scientists and for students. In science education, however, the prevailing view remains that it is an impediment. For this study, we have chosen examples of what we…

Questioning is an important activity in teaching. In medical colleges, on-stage quiz competitions are appreciated by students as well as faculty as they are an engaging way to connect with the discipline. We organized the Physiology Quiz Competition to assess the concepts of functional mechanisms of various organ systems. It was an academic tool…

The next generations of science, technology, engineering, and math (STEM) workers are being trained in college and university classrooms by a workforce of instructors who learn pedagogical practice largely on the job. While inclusive instructional practices and their impacts are increasingly well-studied, this training is difficult to instill…

Despite the growing adoption of the Flipped Classroom (FC) model in higher education, there is limited exploration of its impact on secondary education and students' attitudes toward science. Thus, this study aimed to examine the correlation between secondary school students' perceptions of the Flipped Classroom experience in learning science and…

Energy conversion devices such as fuel cells, metal-air batteries, and electrolyzers have been envisaged as possible solutions for cutting down the continuous accumulation of greenhouse gases resulting from the combustion of fossil fuel. The bottleneck reaction for these devices is the oxygen reduction reaction (ORR) occurring at the cathode. The…

Clathrate hydrates are attractive materials for education because they form from water and familiar compounds, such as carbon dioxide, and are relevant to novel technologies. In this study, an attempt to propose a laboratory experiment was summarized, which used carbon dioxide clathrate hydrate as an educational material with carbon capture…

The central dogma of molecular biology describes the transfer of genetic information from nucleic acids to proteins and stipulates that the system cannot work in the reverse direction. As a fundamental principle in biology, the dogma is as influential as it is controversial. Some commentators have debated the central dogma's empirical accuracy…

Practical experiments enhance students' understanding of basic concepts and promote deep learning experiences in chemistry. The smartphone application of Lab4Chemistry was utilized to replace colorimeters with smartphone camera sensors. Low-cost and readily available materials, including anthocyanin (fresh red cabbage) and common kitchen…

Organic molecules are invisible objects, but they can be visualized and manipulated by using molecular models. The object-based learning (OBL) approach, which is an educational tool developed for museums and collection items, is tailored and applied to a first-year bachelor course of organic chemistry. At the beginning of the course, each student…
