This study surveyed 19 chemistry teachers' stoichiometry pedagogical content knowledge (SPCK) in Ijebu Ode local government area of Ogun state, Nigeria using Malcolm's Physical Science Teachers' SPCK test. The qualitative data were transformed to scores, which revealed the level of chemistry teachers' knowledge of students' prior knowledge,…

The ability to extract structural information from a drawing of a molecule is key to being successful in organic chemistry. One source of difficulty for novices in interpreting structures is that hydrogens bound to carbon are represented implicitly in the often-used line-angle structures. Other representations that explicitly show hydrogens, such…

Chemistry is an essential subject for most science-based undergraduate courses in universities; as such, it is a basic requirement for secondary school students aspiring to study science-related courses in universities. However, the subject has historically been linked to high failure rates and underperformance of students in secondary school…

Teaching the three-dimensional structure of saccharides has consistently been a challenging aspect of organic chemistry courses, impeding students' ability to grasp more advanced topics in biochemistry and food chemistry. In this article, we designed and developed a novel d-glucopyranose model using 3D printing technology for the first time. This…

This thesis identifies and explains the gaps in prior and current applications of representational competence construct in chemistry. Representational competence (RC) describes a set of skills that chemistry researchers Kozma and Russell observed experts demonstrate when engaging with disciplinary representations (Kozma & Russell, 1997; Kozma…

Improving student achievement is one of the most important components of learning, and it is influenced by several variables, including academic resilience, self-regulation, and students' perceptions. This study examined how high school academic resilience, self-regulation, and students' perceptions affect their academic achievement in chemistry…

Chemistry education in Rwandan secondary schools faces challenges, especially after the adoption of a competence-based curriculum that prioritizes student-centered learning. Traditional teacher-centered approaches often result in poor student performance. This study investigates the impact of structured group discussions on chemistry achievement…

The purpose of this study is to "meta"-analytically evaluate research that used chemical bonding-based interventions to improve academic performance. Through "meta"-analysis, the present study used several keyword patterns (e.g., chemical bonding, experimental, chemistry education, science education) via relevant databases…

Nanozyme is a kind of mimetic enzyme possessing unique properties of nanomaterials and catalytic functions of natural enzymes. The nanozymes have the characteristics of high catalytic efficiency and good stability and are widely utilized in medicine, chemical industry, food, agriculture, and environment. This laboratory experiment is designed for…

This study was conducted in the laboratory and Metaverse environment with "Acids-Bases," a science subject related to the Metaverse, one of today's technologies. In line with the purpose of the research, the embedded design of the mixed research method, which combined quantitative and qualitative research methods, was used. The…

Mixed results have been reported on the correlation between clickers and performance. This study investigates the usage of clickers in a voluntary context to answer in-class questions in a General Chemistry class. Scores on an internal chemistry placement exam were used to estimate cognitive ability, as a factor that students can no longer…

Assessment plays a critical role in instruction and curriculum. Existing literature on instructors' assessment practices and related factors has been intensively focused on primary and secondary education. This study extended the contexts of previous literature to post-secondary chemistry education by exploring general chemistry instructors'…

The quality and effectiveness of online teaching-learning are increasingly important with online learning becoming the norm. This cross-sectional survey study aimed to determine the relationship between first-year polytechnic students' perception of chemistry asynchronous lectures and their learning performance. Their perception was determined…

This paper reports on a study that sought to improve pre-service science teachers' performance in the International Union of Pure and Applied Chemistry (IUPAC) nomenclature of aliphatic hydrocarbons using flipped classroom instructional approach (FCA). The study employed a single group pre- and post-test action research design. The sample size…

Metal organic frameworks (MOFs) can have open pore structures with high surface areas and applications in hydrogen storage, carbon dioxide capture, water harvesting from air, chemical separations, and catalysis. The chemical structure of these crystalline solids can initially appear daunting. Simplification by considering the arrangement of the…
