<![CDATA[This study aims to evaluate the learning programme of the Introduction to Environmental Chemistry course of the Chemistry Education study programme in one of the public universities in Bandung City. This study needs to be evaluated and improved because there are still aspects that are not in accordance with 21st century learning as evidenced by document analysis and learning observations. The method used is a qualitative approach and the CIPP (Context, input, process, Product) evaluation model as a tool to evaluate and improve the lecture programme which focuses on the Context aspect in the form of document analysis of the Semester Learning Plan (SLP), the Input aspect in the form of lecturer interviews and the Process aspect in the form of learning observations. The results obtained from the analysis show that there are several findings that need to be evaluated due to the incompatibility of aspects in the SLP document update such as administrative completeness, the General Skills Aspect (GSA) 1 listed is not in accordance with the Context of Learning Outcomes (CLOs), based on interviews with teaching lecturers it is stated that problem-based learning (PBL) with the context of validated environmental issues in relevant theoretical content and in the aspect of the learning observation process it was found that there were aspects of learning practices that were not in accordance with the SLP document reference. The evaluation also highlighted the importance of updating and adjusting learning media to be more interactive and relevant to the context of environmental issues. The assessment of the last three years shows the potential to further develop programmes can to improve students' higher order thinking skills]]>

<![CDATA[Misconceptions can significantly hinder the learning process. To address this, various diagnostic instruments such as two-tier (2TMC), three-tier, and four-tier multiple-choice questions have been introduced. However, as the number of tiers increases, identifying misconceptions becomes more complex. Therefore, this study employs the Item Option Characteristics Curve (IOCC) to identify misconceptions by calculating the probability of each option being selected. The Representational Systems and Chemical Reactions Diagnostic Instrument (RSCRDI) was administered to 185 pre-service teachers across three universities in Indonesia. The data was analyzed using Winstep software to generate the IOCC for each item. The analysis revealed that each item in the phenomenon and reasoning tiers contains distractors that could interfere with the option selected by pre-service chemistry teachers. While the alternative answers identified using traditional methods (commonly used since the introduction of 2TMC) were mostly similar to those identified by IOCC, the IOCC provided more detailed insights. Specifically, it highlighted unexpected curves after 0 logits, identified less effective distractors, and revealed inconsistencies in the most influential distractors. These findings suggest that the IOCC provides richer, more detailed information and can be a valuable alternative framework for analyzing 2TMC items to unfold misconceptions.]]>

<![CDATA[Chemistry concepts are generally abstract so they require teaching materials that visualize those abstract concepts. The aims of this study were to develop a Basic Chemistry E-Book enhance with multiple representations and STEM approach. This study used a research and development model modified from the ADDIE model which consists of 5 stages, namely: (1) Analysis (analysis of students’ characteristics and course objectives), (2) Design (design of e-book and research instruments), (3) Develop (e-book production), (4) Implementation (expert judgement and field trials), and (5) Evaluation (the effectiveness test and revision of e-book). Research result showed that the feasibility of e-book based on the expert judgement got 93.75% as a score on the material feasibility component, 100% as a score of feasibility component and 95.40% as a score of the language and STEM component. Furthermore, the results of small-scale field trials obtained a percentage of 86% and large-scale field trials obtained a percentage of 87%. The effectiveness test of e-book got score 0,643 means e-book was effective enough for using in learning chemistry. Based on this study, e-book for Basic Chemistry Course based on multiple representations with the STEM approach is appropriate for being used in general chemistry course.]]>

<![CDATA[This study examines the significance of Pedagogical Content Knowledge (PCK) in chemistry education, specifically its role in pre-service chemistry teacher training. Through a comprehensive review of 14 articles, the research identifies key themes related to the development, application, and impact of PCK on chemistry teaching practices. The majority of the articles emphasize the importance of integrating PCK into teacher training programs, highlighting the effectiveness of practice-based and constructivist learning approaches to bridge the gap between content knowledge and teaching strategies. PCK was found to influence teaching methodologies, allowing teachers to tailor their approaches to specific chemistry topics and manage classroom dynamics effectively. However, the study also reveals significant gaps in the application of PCK in classroom management and assessment practices, areas that require further exploration. The findings suggest that although PCK plays a critical role in improving teaching quality, its integration into classroom management and assessment is still underexplored. The research recommends future studies to focus on these areas, particularly in secondary and higher education settings, to refine the application of PCK across various aspects of chemistry teaching. This research contributes to a deeper understanding of PCK's role in teacher preparation and offers directions for future research to enhance the development of pre-service chemistry teachers and improve overall teaching effectiveness.]]>
