Abstract

This study aims to analyze and describe the characteristics of cognitive test items for physics subjects using the 1-PL model or the Rasch model. This research is quantitative descriptive. The subjects in this study were students of class XI IPA SMA 2016/2017 academic year in the city of Tanjungpinang as many as 352 students. The data collection technique in this research is documentation. The data used is the cognitive test response for Physics class XI, which consists of 20 multiple choice items. Cognitive test in the form of kinematics learning achievement. The kinematics material measured includes uniformly straight motion, uniformly changing straight motion, parabolic motion, uniform circular motion, and uniform circular motion. The validity of the test instrument is proven by the content validity using the Pearson product-moment formula calculation. While the reliability of the test instrument is estimated using Cronbach Alpha, it is known that the magnitude of the reliability coefficient is 0.5324. The results of this study were analyzed using the R program based on the 1-PL model or the Rasch model. Based on the results of the analysis, it is known that the item difficulty level is in the range of -3.379 to +4.328 with a discriminating power of 0.553.
