We address the extent to which students developed expert attitudes in the individual disciplines of biology, chemistry and physics during their degree programme. By attitudes we mean the way students think about the sciences compared to discipline experts. We used the standard CLASS survey instrument to compare student attitudes to biology,…

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…

Laboratory learning has been the focus of significant creativity for educators. Engaging students in "real world" contexts or using their knowledge in laboratory exercises in a meaningful way requires that students are engaged in the practice of science. The role of decision-making around this practice of science, say for the analysis of…

The Instrumental Analytical Chemistry course, taught in the fifth semester across several programs at the Faculty of Exact Sciences of the National University of La Plata, places a significant emphasis on high-performance liquid chromatography (HPLC). This versatile analytical technique is essential for the separation, identification, and…

This study investigates how preservice science teachers (PSTs) develop and utilize representations in chemistry when they engage in argument-based inquiry environments using the Science Writing Heuristic (SWH) approach. The data-transformation variant of convergent design, which is a particular form of mixed method research, was used in the study.…

Understanding molecular structure is fundamental in chemistry education. However, commercially available molecular model kits are often expensive and are not always present in educational institutions. Here we present "ChemBotCap," an innovative, low-cost, and engaging alternative for modeling simple inorganic and organic molecules using…

Background/purpose: The study aimed to investigate the effectiveness of teaching based on multiple intelligences in acquiring chemical concepts and the ability to explain household chemical phenomena among basic-stage students. Materials/methods: The study employed an experimental method with a quasi-experimental design for two non-equivalent…

The societal and industrial relevance of chemistry has established its status as a compulsory subject in numerous national curricula. However, previous research highlights significant challenges faced by students in learning chemistry, largely attributed to its abstract nature and the multiple ways chemical concepts are represented. These…

The importance of introducing students to mechanistic reasoning (MR) early in their schooling is emphasised in research. The goal of this case study was to contribute with knowledge on how early primary students' (9-10 year-olds) MR in chemistry is expressed and developed in a classroom practice framed by model-based inquiry. The study focuses on…

Different goals of high schools and vocational schools in Indonesia become the main factor causing the distinction of preparedness of chemistry teachers in using the Science, Technology, Engineering, and Mathematics (STEM) approach in their teaching. Yet the High School Chemistry Teachers (HSCT) and Vocational School Chemistry Teachers (VSCT) need…

Teacher enthusiasm is known to affect students' learning in traditional classroom environments, but it is unclear how displayed teacher enthusiasm can optimize learning of chemistry procedural knowledge in multimedia learning environments. In this context, the present study used eye-tracking technology and quantitative analysis to examine how…

Owing to the critical role of stereochemistry in biotechnology, medicine, and industry, it must be well represented in undergraduate lab curricula. To achieve these stereochemical laboratory requirements without sacrificing existing lab techniques, we modified two standard laboratory experiments to include chiral GC analysis as follows. (1) The…

Applying bibliometric techniques to blended learning research is still relatively uncommon. This study employs bibliometric analysis, employing data from the Scopus database and VOSviewer to show papers published between 2012 and 2022. The study's sample is made up of publications on blended learning in science that have been indexed by Scopus and…

An organic chemistry experiment designed for senior undergraduates focuses on bifunctional catalysis, a critical yet often omitted topic at the undergraduate level, but essential for advanced studies in chemistry. By utilization of a tertiary amine-thiourea catalyst in the asymmetric Michael addition reaction, the experiment showcases the…

Data are an essential factor in the fourth industrial revolution, demanding engineers and scientists to leverage and analyze their potential for significantly improving the efficiency of industrial processes and their control systems. In classical industrial process control systems, the models are constructed using linear data-driven approaches,…
