The Development of Physics Objective Tests Based on PISA for Sound Wave Topics in High School

Abstract

The purpose of this study is to develop a PISA-based physics objective test instrument for sound wave material in high school according to good test qualification standards in terms of index validity, reliability, discrimination, level of difficulty, and distractor effectiveness. This study is a type of research and development (R&D). The model used is Analysis, Design, Development, Implement and Evaluation (ADDIE). The analysis stage resulted in minimal variation in the assessment and students still lacking PISA-based physics questions, especially on sound wave material. The material for developed physics problems includes the magnitude of sound waves, reflection and refraction, resonance, sound intensity, and the Doppler effect. The design stage resulted in 45 items based on the PISA scientific literacy competency which were classified into three competency standards, namely: explaining scientific phenomena; evaluate and design scientific research; interpret scientific data and evidence. The development stage obtained 44 items in the very valid category based on content validation by 5 experts, both in terms of material, construct, and language. The results of the implementation and evaluation stages show that of the 45 questions developed, 38 questions have met the criteria for good test quality, based on index validity, reliability, discrimination, difficulty level, and distractor effectiveness in small group trials and large group trials.
