Virtual classrooms based on the metaverse or virtual reality are useful and effective for imparting basic chemistry concepts. Interactive and immersive environments can effectively teach fundamental chemistry concepts, such as chemical bonding and formulas, thereby making these otherwise abstract and intangible ideas more accessible and…

No scientific concept in the twenty-first century has garnered more attention from scholars outside the scientific community than the Anthropocene. Despite the official rejection by the geological community in March 2024 of the proposal for an Anthropocene Epoch as a formal unit of the Geological Time Scale, it is expected to remain an invaluable…

Integrating agent-based models (ABMs) has been a popular approach for teaching emergent science concepts. However, students continue to find it difficult to explain the emergent process of natural selection. This study adopted an ontological framework--the Pattern, Agents, Interactions, Relations, and Causality (PAIR-C)--to guide the design of…

This study aims to investigate the effect of the teaching model developed for hot conceptual change on middle school 7th-grade students' understanding of the Nature of Science (NOS) aspects. In this qualitative and exploratory study, activities were carried out with 24 students of two classes in a village school in the South Marmara region using a…

Multiple external representations (MERs) are useful for teaching complex content in science education. An open question is whether there is an especially effective way to sequence MERs. On the one hand, the so-called concreteness fading approach suggests starting instruction with more concrete representations and proceeding stepwise to more…

Video instruction has been widely studied and is generally considered as effective as live instruction for teaching scientific concepts and procedures. However, there is limited research on the effectiveness of prerecorded videos for teaching more challenging content. This study conducted a controlled experiment on over 300 high school students to…

We investigated the effect of short-term teaching (3 weeks) using image analysis on gymnasium/secondary school students' (ISCED3A) skills (science process skills, SPS) and knowledge using Fiji (ImageJ) software. The theoretical teaching was combined with IT-based education (measurement of the area or signal intensity on photos from scientific…

Secondary school students find it difficult to write elaborated causal explanations of scientific phenomena. They frequently present their own opinions and write descriptions of their observations rather than linking observations with logical chains of causal reasoning, underpinned by a theoretical framework, to provide explanations of scientific…

This study examined the effects of multisensory storytelling facilitated through iPads on the understanding of science concepts related to botany among students with severe intellectual disability (ID). A single-subject, multiple- baseline design was used to evaluate three participants diagnosed with severe ID. During the intervention phase,…

With the better understanding of human genome and genetic contributions to human complex diseases, more and more clinical genetic tests have been developed for the prevention, diagnosis, and treatment of human diseases. This has raised new challenges to classroom teaching of medical genetics (MG) in medical education of undergraduates, who are…

This study aimed to examine the impact of a context-based relating, experiencing, applying, cooperating, and transferring (REACT) strategy on the scientific reasoning (SR) abilities of tenth grade students. A mixed-method approach and convergent embedded experimental design were used. One hundred thirty-one students participated in the study in…

The effectiveness of a formal charge method to draw Lewis structures that was developed by Curnow was studied quantitatively by direct comparison of two groups of students: one of which was taught the new formal charge method and another that was taught a traditional method. Students' marks on a common assessment were found to improve by…

The periodic table is a fundamental tool used in chemistry classes that allows students to systematically understand different types of elements and their physical and chemical properties. While many textbooks emphasize the historical process of classifying substances, they often superficially elucidate the achievements of chemists such as Dmitry…

We propose an innovative approach to teaching friction. Our approach aims to educate students on its microscopic nature by highlighting its origin in intermolecular interactions. We have designed a teaching sequence (TS) based on a set of experimental investigations of the properties of a gecko-inspired tape at different length scales. The TS has…

Graphic Organizers are visual and graphic display that illustrates the correlations between facts, terms, and ideas with a learning task. Integrating Graphic Organizers can enhance the efficiency of the teacher's delivery of lessons and students' learning. However, no study had been conducted in using graphic organizers in the process of teaching…
