Abstract

Platinum Group Metals (PGM) is one of the topics in elemental chemistry in higher education that is important to teach, considering its major role in various industries. PGM is important in various industrial applications, especially as a catalyst in the automotive, electronics, and environmental technology sectors. This study aims to analyze the topic of Platinum Group Metals (PGM) in elemental chemistry teaching in chemistry education study programs in Indonesia with a focus on its relevance, depth, and pedagogical approach. This study is a qualitative descriptive study with a document analysis approach. Data were collected through analysis of Semester Learning Plan documents for inorganic chemistry courses that contain elemental chemistry topics from several universities in Indonesia. Data were analyzed through the following stages: coding, content analysis, and descriptive qualitative. The study's findings indicate that the discussion of PGM on elemental chemistry is still limited and is taught together with other transition elements. The depth of the material also does not reflect the relevance of PGM in industry, modern technology, and sustainable use. This study recommends increasing elemental chemistry learning by teaching PGM topics in more depth as a provision for students to face challenges in the chemical industry. Interdisciplinary teaching approaches and case studies are also needed to strengthen conceptual understanding and student engagement.

Abstract

This study aims to demonstrate how a course design approach based on explorative research involving systems thinking can be implemented by recovering Rare Earth Elements (REEs) using Deep Eutectic Solvents (DES). The method used in this research is Design-Based Research (DBR). The instruments used were questions regarding the measurement of leaching samples from results/characterization, short questions about concept maps, and student response questionnaires. Data from measurements of leaching samples was measured using a Fourier Transform Infrared Spectrometer (FTIR), data about concept maps was measured by the number of component and process concepts in the context of electronic waste recycling that students were able to identify, and student response data was measured using a Likert scale. Based on the research results, recovery of REEs can be done using DES. It can be shown by a shift in the peak vibration of 497.65 cm-1 from the sample before leaching to a vibration of 449.43 cm-1 after leaching. In addition, this study yields new insights into the perceptions of future pre-service chemistry teachers regarding the possibility of new types of DES in the context of chemistry learning. According to pre-service chemistry teachers, recovering REEs from electronic waste and applying DES are interesting as a new context for laboratory learning. Context-based design of research activities can enhance system thinking and interest in chemistry. The results of study showed increased student’s systems thinking abilities, as shown by the component and process concepts that emerged from the pre-test by 652 concepts while the post-test increased by 1208 concepts.

Abstract

This study aims to analyze the computational thinking (CT) skills of pre-service chemistry teachers using a set of twelve test items adapted from the international CT Bebras Challenge. The items represent three difficulty levels: easy, medium, and hard. The CT components assessed include algorithmic thinking, abstraction, and pattern recognition. A descriptive quantitative method was employed, involving students from a chemistry teacher education program. The responses were scored and analyzed using descriptive statistics to identify trends in students’ CT performance across components and difficulty levels. The results show varied levels of proficiency, with higher performance in pattern recognition tasks and lower performance in algorithmic thinking. These findings highlight the importance of embedding CT skill development in chemistry education and teacher training curricula.
