This study explores the importance of general chemistry as a prerequisite for organic chemistry lecture courses. The students taking organic chemistry were categorized into three groups: (1) those who had finished the prerequisite before starting organic chemistry, (2) those who had not finished the prerequisite before starting organic chemistry,…

Our goal as educators should be to help our students become well positioned to achieve future success. To develop effective strategies for accomplishing this objective, we must first understand the root causes of success. Thus, to best serve undergraduate students who are taking organic chemistry courses, we must understand the attributes that…

Solving organic chemistry reactions requires reasoning with multiple concepts and data (i.e., multivariate reasoning). However, studies have reported that organic chemistry students typically demonstrate univariate reasoning. Case comparisons, where students compare two or more tasks, have been reported to support students' multivariate reasoning.…

This study aimed to develop a comprehensive diagnostic tool for assessing upper-secondary school students' understanding of isomers, expanding upon existing two- and three-tier conceptual diagnostic methods. By incorporating 'Confidence Rating Factor' tiers within the answer and reason sections, a four-tier test was designed and developed. This…

STEAM (Science, Technology, Engineering, Arts, Mathematics) learning is designed to contextualize the abstract concepts of science in chemistry learning. Integration STEAM in chemistry learning needs a learning model to help students understand real-world problems. For this reason, STEAM-PBL (Project Based Learning) was employed. This paper…

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…
