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…

Despite the growing field of research focusing on the benefits of learning science in the outdoors where students have direct connections with the natural world, teachers report that challenges such as time and test preparation discourage outdoor science instruction. Additionally, many teachers feel ill-equipped and a lack of support from…

Background: Teaching and learning of nature of science (NOS) is an explicit goal in the core science curriculum in Norway. Yet there is little understanding of how the content of the current textbooks in certain educational pathways such as vocational training addresses NOS. Purpose: The aim of this study is to contribute to research on NOS in VET…

One expected outcome of physics instruction is for students to be capable of relating physical concepts to multiple mathematical representations. In quantum mechanics (QM), students are asked to work across multiple symbolic notations, including some they have not previously encountered. To investigate student understanding of the relationships…

This study aims to explore the meanings communicated by young children with visual cultural semiotic resources available in the science classroom. It is a case study in an Early Childhood Education classroom of 23 children (3-4 years old) and their teacher, all engaged in a long-term science project about snails. We focus on the analysis of two…

Virtual simulations are a very useful educational resource to improve the teaching of chemistry. Their use makes it possible to facilitate the comprehension of concepts, promotes the development of scientific competences and even improves student attitudes toward chemistry. However, it is important to point out that a simulation by itself is not…

While innovation commonly stems from the Entrepreneurial Mindset (EM), its integration within chemical engineering curricula has been notably limited. However, a shift is occurring as both private and public initiatives are now directing resources and attention toward equipping students for prosperous careers. This paper delineates the successful…

This study focuses on how science teachers' Pedagogical content knowledge (PCK) can be captured and developed with the support of Content representation (CoRe) in combination with video-based reflection when they plan, teach, and reflect on their teaching in sustainable development (SD). The theoretical framework is based on PCK, and the Refined…

This paper answers the call for the importance of integrating the Islamic worldview into science classes. This research provides insights into science teachers' experiences of integrating science and Islam, as well as additional surveys to reveal gains in student understanding. This research consists of two stages. Study 1 used phenomenology and…

The lecture approach remains a common teaching method in chemistry education. This study aimed to investigate its impact on students' attitudes towards chemistry, focusing on overall, cognitive, affective, and behavioral dimensions. A pre-test and post-test control group design was employed. This study involved 30 first-year undergraduate…

In this article, we present a framework of culturally relevant science and mathematics pedagogy (CRSMP), which is grounded in the tenets of culturally relevant pedagogy. It delineates practices ranging from the most accessible and easy-to-implement, to the most challenging and often contentious ways to teach mathematics and science. We provide…
