Resonance is a fundamental chemistry concept first introduced to students in General Chemistry I, reintroduced in Organic Chemistry I, and then utilized throughout other higher-level chemistry courses. A molecule or ion can be said to exhibit resonance when it can be represented by two or more chemical structures (i.e., Lewis structures) that…

When designing a study, the sampling method for selecting research participants is an important decision with a host of considerations. When designing a professional development (PD) program with a limited number of spaces, the method of choosing participants from the applicants is also important. When research and professional development are…

Resonance is a foundational organic chemistry concept, but it is consistently misunderstood by undergraduate students. The development of a concept inventory--a multiple-choice assessment where the incorrect answer choices stem from commonly held alternate conceptions--on the concept of resonance could help organic chemistry instructors quickly…

Numerous academic studies in the field of chemical education utilize the conceptual framework of three distinct tiers that underlie the instruction and acquisition of chemical knowledge. This framework is commonly depicted in a chemistry triangle, with the vertices denoted as macroscopic, submicroscopic, and symbolic. The ability of students to…

The aim of this study is to investigate the results of the flipped classroom model, which was prepared and applied in collaboration with colleagues, on the academic success on stereochemistry one of the topic the organic chemistry course of pre-service chemistry teachers, the views of the pre-service chemistry teachers about the flipped classroom…

The study diagnosed chemistry teacher trainees' difficulties in naming and writing structures of spiro and bicyclic compounds. The case study design was conducted in a constructivist environment to enhance chemistry teacher trainees' ability to construct, represent, and interpret the structural formulae of spiro and bicyclic compounds. Purposive…

This study reviewed the green and sustainable chemistry education (GSCE) research that provided training at the tertiary level from 2000 to 2024. The Web of Science and ERIC databases were screened using title and abstract review. In total, 49 studies were analysed. The analysis instrument has two main parts, namely, general characteristics of the…

This study aimed to identify science teacher candidates' mental structures about the concept of the atom. This study included 120 science teacher candidates who were chosen using the convenience sampling method. This research is a phenomenological study. The data on students' mental models of the atom was collected using a metaphor form and an…

The purpose of this study is to determine pre-service chemistry teachers' knowledge of the oxidation number and coordination number in coordination compounds. Data were collected from 31 pre-service chemistry teachers through a 4-question scale, and the second question of the scale consisted of 8 sub-questions. The results showed that the…

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 article is devoted to the preparation of future chemistry teachers for their motivational influence on pupils. It analyses the experience of the course "Means of Motivation in Chemistry Teaching," which is designed as an elective course in the undergraduate preparation of future chemistry teachers at our university. It looks closely…

In this paper, the main purpose is to describe the development and use of three flowcharts for identifying types of isomers and naming coordination compounds. The first flowchart is designed to help students identify the type of isomers between the two coordination compounds. The second one is is designed to identify the type of stereoisomerism.…

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…

Holism evolution states that although energy, matter, life, consciousness and the human personality are independent and different substances/levels of evolution, they are holistically and intimately related. This paper presents the findings from teaching chemistry to high school science students and post-graduate university science-education…

This study aimed to develop a two-tier test to identify misconceptions of pre-service teachers about chemical equilibrium. The sample was made up of 135 pre-service chemistry teachers at Farhangian University in Iran (70 female and 65 male) who were spending the final semester of the eighth semester of the teacher training programme. After…
