Colloidal stability is one of the most important criteria in the application strategy of colloidal nanoparticles in the continuous phase. The branches include ecology, involving coagulation as a purification method; medicine as nanocarriers; biology as blood coagulation, etc. A chemist versed in these concepts is a high-performing chemist in…

This study explores the ontological perspective in analyzing students' problem-solving related to mechanical energy conservation. The research involves 18 high school students whose explanations were qualitatively analyzed using an extended ontological framework. Initially, students predominantly employed matter-based predicates and…

The objective of this descriptive study is to provide a detailed examination of science teachers' perspectives regarding scientific knowledge, science learning, science concepts, and science teaching. A total of 304 science teachers created metaphors to express their cognitions about the epistemological aspects of their work. A specifically…

In this article, we tackle the phenomenon of what seems to be a misunderstanding between science education theory and philosophy of science--one which does not seem to have received any attention in the literature. While there seems to be a consensus within the realm of science education on limiting or altogether denying the explanatory role of…

Although previous research provides insights into how gestures function as a pedagogical tool, relatively little is known about how gesture is related to language, together creating a key meaning-making teaching resource. Drawing on the system of logico-semantic relations in Systemic Functional Linguistic theory and McNeill's description of…

The biology laboratory at State Senior High School (SSHS) 1 of Rasau Jaya has not been fully utilized, necessitating evaluation and improvement. This study aimed to determine the suitability of laboratory facilities and infrastructure at SSHS 1 of Rasau Jaya in relation to the existing standards set by the national regulations. This is a…

The United Nations (UN) Sustainable Development Goals (SDGs) are a comprehensive call to action for a better world adopted by the UN member states in 2015. Education for Sustainable Development (ESD) is a framework for incorporating the urgency and practicality of the SDGs into curricula of all kinds. We infused a junior-level undergraduate cell…

Science educators face significant challenges in preparing learners with the skills and knowledge necessary for 21st-century functional scientific literacy. This stems from high expectations of students and a growing demand for them to apply their learning to complex issues with political, social, environmental, and economic dimensions. The…

Citizen science has the potential to promote an understanding of science and to represent science in school authentically. Still, its implementation into formal education encounters tensions between scientific and educational goals. Factors for success and hindrances of the implementation of citizen science projects in the classroom can be…

Purpose: In this article, the authors explore one way that teacher preparation programs and elementary schools can collaborate to enhance science instruction for elementary school learners. This paper provides an overview of a project where a teacher candidate worked with six classroom teachers to organize science materials and prepare for science…

This review extends on previously reported findings in which students were asked to construct Reaction Coordinate Diagrams (RCDs) de novo. Instead of asking students to construct RCDs, this study explores students' understanding of kinetics and thermodynamics when provided with mechanisms for the Aldol and Claisen condensations. Data was collected…

Hybridization is a bonding model, universally used in organic chemistry, which allows consideration of two-electron localized bonds in organic molecules. Without hybridization, it is almost impossible to describe aspects such as hyperconjugation for the stabilization of carbocations and alkane conformers. Hybridization is often presented in…

Scientific modeling is a core practice of scientific inquiry. Students' engagement in modeling can be enhanced by attending to epistemic criteria, which in science are standards used to evaluate the validity and accuracy of scientific models. While prior research has focused on students' development and use of epistemic criteria in scientific…

Communities of practice in STEM education are important for promoting the improvement of teaching in the postsecondary curriculum. One community in particular is the Interactive Online Network of Inorganic Chemists (IONiC). IONiC aims to advance inorganic chemistry education through the creation of curricular materials (i.e., learning objects).…

Raman spectroscopy, a powerful vibrational spectroscopic technique widely used in chemistry, materials science, and environmental analysis, provides critical molecular insights through spectral fingerprints. However, undergraduate students often lack proficiency in optimizing experimental parameters, interpreting vibrational modes, and applying…
