Abstract

Abstract: This program was designed to bolster high school teachers' expertise in applying the case method to math and science instruction. Over six months, 19 teachers from Lampung Province participated in a structured series of lectures, workshops, and interactive sessions. The pretest and posttest evaluations highlighted significant gains in both conceptual understanding and the ability to develop case-based teaching materials. Participants were also trained to design student worksheets with digital tools like Canva, integrating scientific and socio-scientific scenarios into their lessons. By doing so, the program nurtured critical thinking, problem-solving, and environmental awareness among educators and their students. By equipping teachers with effective strategies for embedding real-world cases into their teaching, the initiative has taken a meaningful step toward advancing innovative practices in chemistry education and other scientific disciplines. To amplify its impact, expanding the program to additional regions and incorporating more classroom simulations is recommended. Such steps would further refine teachers' skills and boost student engagement with complex scientific topics. Emphasizing creativity, critical thinking, and real-world connections, this initiative represents a significant stride in enhancing high school science education. Keywords: case-based instruction, high school teachers, socioscientific issues.

Abstract

The abstract and symbolic nature of chemistry presents significant learning challenges for students, particularly in the understanding of foundational concepts through a variety of representations. It's tougher to teach well, especially in Indonesia, because there are not many trustworthy instruments to measure students' interpretative skills, which are very important for representational competence. The goal of this study was to fill this gap by creating and testing a reliable assessment tool called the Assessment of Representational Competence in Fundamental Chemical Laws (ARC-FCL), which was meant to measure the interpretative skills of Indonesian senior high school students.  The Define, Design, and Develop stages of the 4D model were employed in the Research and Development process of this study design. The Kozma-Russell framework and the Three-Dimensional Learning Assessment Protocol (3D-LAP) helped shape the instrument's development. The ARC-FCL test has two levels of multiple-choice and essay questions about the laws of Lavoisier, Dalton, and Gay-Lussac. Two chemistry education professors and one experienced instructor reviewed the content to ensure its validity. Researchers got real-world data for psychometric analysis from 30 11th-grade students at a senior high school in Lampung, Indonesia. The study looked at item validity using Pearson correlation, item discrimination, and internal consistency reliability using Cronbach alpha. All three designed items had great validity, with correlation values over the key threshold of 0.361 and good discrimination indices between 0.50 and 0.75. The instrument was somewhat reliable, with a Cronbach alpha coefficient of 0.572. This is fine for a formative diagnostic tool at this early stage of development. Item analysis also showed that students had the most trouble with the question about the Law of Multiple Proportions.  In conclusion, this study developed a valuable and valid instrument for identifying the specific challenges faced by students when attempting to comprehend sub-microscopic representations of fundamental chemical principles. As a formative assessment instrument that fits with the Kurikulum Merdeka, the ARC-FCL is quite useful for Indonesian teachers. It encourages a move from memorizing things by heart to comprehending them better and learning how to do science. Future work should be focused on adding more items to the bank to make it more reliable and cover more ground. Keywords: representational competence, assessment instrument, interpretive skills, basic chemical laws, 4D model, instrument validation.
