Abstract

Learning physics requires literacy skills in understanding concepts, critical thinking, and connecting theory to real life. An ethoscience-integrated approach to physics education combines science and culture by highlighting local wisdom to create a more meaningful learning experience, enabling students to grasp concepts without misconceptions while also gaining an understanding of their local culture. This study aims to develop an ethoscience-based multiple-choice test instrument to analyze students^ cultural literacy skills regarding renewable energy material. These cultural literacy indicators include understanding cultural diversity or local wisdom, understanding cultural complexity, understanding cultural values, and concern for culture. This study employed the Research and Development (R&D) method with a development design adapted from Cennamo and Kalk, which includes the stages of definition, planning, demonstration, development, and presentation. The research subjects were students in classes X.1, X.2, and X.3 at Nasima High School in Semarang. Data collection was conducted through questionnaires and tests. Data analysis techniques involved validating the content of the instruments and estimating their validity, reliability, difficulty level, and discriminant power using the Classical Test Theory (CTT) model with the assistance of ITEMAN (Item and Test Analysis). The results of the study showed an Aiken^s V value of 0.92, which is higher than the table value of 0.73, thus falling into the valid category. Additionally, the analysis results also indicated that the instrument^s reliability was 0.68 (high category), the average difficulty level was 0.53 (moderate category), and the average discriminative power was 0.26 (adequate category). Thus, the multiple-choice test instrument with an ethnoscience component is suitable for analyzing students^ cultural literacy skills.
