Abstract

Purpose of the study: This study aims to develop and validate a Rasch Model-based energy knowledge, attitude, and behavior assessment instrument to measure energy literacy among high school students. Methodology: The research design followed the stages of theory-based instrument development and the Rasch modeling approach. The quantitative approach and instrument development process were carried out through the stages of item preparation based on literature review and theoretical indicators, validation by experts, and field testing of 50 participants. Main Findings: The knowledge instrument has high quality, obtained as much as 9 data showing a fit for the Rasch model, such as MNSQ infit and outfit values ranging from 0.84 to 1.25. and positive point measure correlations. Instrument reliability shows infit and outfit results that are still within the ideal tolerance range, obtained sequentially the person reliability values of knowledge, attitude, and behavior of 0.50, 0.76 and 0.75. So that the instrument is suitable for accurate and consistent measurement. Novelty/Originality of this study: this study provides innovation in the energy literacy measurement literature (knowledge, attitude, and behavior) with an in-depth evaluation of item performance and respondent ability distribution using empirical and applicable methods for the development of evidence-based and Rasch model-based assessment instruments.

Abstract

Purpose of the study: The low level of science literacy among Indonesian students requires innovative and contextual learning approaches. This study aims to develop and test the validity of an Ethnoscience-Based Teaching Module on the subject of Vibrations and Waves. The uniqueness of the module lies in its deep integration of the local wisdom of East OKU Regency as a learning context to bridge abstract scientific concepts with the cultural reality of students. Methodology: This study used the Research and Development (R&D) method with a 4-D model, limited to the Develop stage. Validation was carried out by four experts (material, media, language, and culture) using adapted assessment instruments. Quantitative data were analyzed using Aiken's V coefficient. Main Findings: The developed ethnoscience-based teaching module was declared "Highly Valid" with an average Aiken’s V score of 0.90. All validation aspects scored highly: subject matter (0.90), media design (0.88), language (0.85), and cultural integration (0.95). The module is therefore feasible for further testing. Novelty/Originality of this study: The developed module has met the eligibility criteria in terms of content, design, language, and authentic cultural integration. The implication of this research is the availability of valid and contextual teaching materials, which are ready to be further tested for their effectiveness in learning to improve science literacy while building students' cultural awareness.
