This study focuses on exploring pre-service science teachers' conceptual integration understandings in explaining the subject of metabolism with the concepts of physics and chemistry. Action research was employed in this study. Nine pre-service science teachers taking the General Biology II course participated. Participants were taught metabolism…

Fluorescence-related experimental techniques play an important role in biochemistry, molecular biology, and cell biology. However, fluorescence-related experiments are rarely included in the laboratory courses of most Chinese universities. This is mainly due to the conflict between large class size (50-60 students in one room) and funding/space…

Heterocycles, more specifically those containing nitrogen, make up a family of molecules with great pharmaceutical potential. Many approved drugs, notably anticancer drugs, contain a nitrogen-based heterocycle. To expose students to this class of molecules, we used the Paal--Knorr reaction for the synthesis of edaravone, a pyrazolone derivative.…

Recently, the question of which version of content knowledge (CK) is suitable for pre-service teacher (PST) development has gained prominence in teacher education research. A version of CK argued to be appropriate for science PST development has been introduced and referred to as teacher-related science content knowledge (TerSCK). This CK version…

High school students' chemistry self-efficacy (CSE) and scientific identity (SI) are not well understood in the high school chemistry classroom. The purpose of this research was to quantitatively investigate the interaction between gender and giftedness on students' CSE and SI in a suburban high school chemistry classroom, with and without…

Students' sense of belonging impacts their affect, motivation, well-being, and academic success. Sense of belonging is considered context-dependent as what determines one's belonging differs across contexts. This study explores how sense of belonging manifests among post-secondary, introductory chemistry students. This context is important given…

The question of precollege physics access and performance has been a persistent concern when considering the goal of diversifying participation in post-secondary STEM study and careers. This observational study examined school-level academic and demographic predictors of high school physics enrollment and performance in the USA. Due to the…

Chemistry is often daunting for college students, contributing to high attrition rates in STEM majors. This study explored students' perceptions of the challenges in studying chemistry, including task effort and emotional costs. We examined how these perceptions, along with goal approaches, impact academic performance and retention in general…

The current study aimed to criticize the existing literature on the utilization of artificial intelligence (AI) and machine learning (ML) in teaching and learning chemistry. A comprehensive critical literature review was conducted using electronic databases such as Scopus, PubMed, ISI, Google Scholar, ERIC, Web of Science, and JSTOR. In this…

Science, technology, engineering, and mathematics (STEM) is the leading education reform worldwide, yet many teachers need more knowledge and confidence to teach integrated STEM. This study examines the initiative of teaching a STEM-integrated approach through the collaboration of mathematics and science university lecturers and preservice…

This paper presents an analysis of the use of multimedia and hands-on models on university students' understanding of stereochemistry. The relationship between students' scientific reasoning skills and their understanding of stereochemistry was also determined. Two groups of second-year chemistry students from the State University of Malang taking…

Scholars as exemplars and their linked eponyms play a significant role in education. Since the discovery of the periodic law in 1869, perceptions of Mendeleev and his eponyms may have shifted. With the aim of assessing the historical and current portrayal of Mendeleev and his eponyms in chemistry textbooks and on the Internet, content analysis of…

The pharmaceutical and medicine manufacturing industry has become the largest industrial sector for the employment of chemists, indicating a need for experiments with a pharmaceutical sciences context in the undergraduate chemistry curriculum. In the pharmaceutical industry, testing drug dissolution is a key analytical task for solid oral dosage…

The integration of Virtual Laboratories (VLs) into blended learning environments in science education offers a multifaceted educational experience that bridges the gap between theoretical knowledge and practical application. This approach provides dynamic, interactive learning opportunities that can be customized to meet various educational needs…

Transition from high school to higher education poses a significant challenge for students, particularly in chemistry, where students' prior laboratory experience is varied. Traditional laboratory education, focusing on chemical knowledge, scientific methodology, and practical skills, does not focus on the development of translational skills and…
