Abstract

This study aims to analyze the item quality of a conceptual understanding test on momentum and impulse. The analysis includes validity, reliability, difficulty level, and item discrimination using the Rasch model. This descriptive quantitative study involved 60 twelfth-grade science students from a high school in Bandung Regency. The instrument used was a 25-item multiple-choice conceptual understanding test on momentum and impulse, scored dichotomously. Student responses were analyzed using MINISTEPS software. The results showed item reliability of 0.82 (logit reliability) and 0.85 (item reliability). Cronbach's alpha coefficient also indicated good reliability at 0.85. Of the 25 items, 4 items did not meet the specified quality criteria. However, overall, most of the items on the conceptual understanding test of momentum and impulse met the quality criteria. These results indicate that the developed research instrument can be effectively used to measure students' conceptual understanding.
