Rasch model analysis of physics test of HOTS on the topic of elasticity and hooke’s law

Abstract

This study aims to measure the quality of the physics learning outcomes test instrument based on high order thinking skills (HOTS) on Elasticity and Hooke's Law and to classify students based on their ability to work on test items. This study uses a quantitative approach. The research was conducted at Sedayu 1st Senior High School with 60 students at eleventh grade in science program as test subjects in the first semester of the 2022/2023 academic year. The data collection technique is done by testing technique. The instrument used is in the form of multiple-choice test questions with 5 alternative answers. The number of test items is 30 test items. The results showed that: first, 27 test items fit the criteria for acceptance of good test items, which can then be used to measure student learning outcomes for physics subjects in Elasticity and Hooke's Law. Three test items are not by the acceptance criteria for good test items, so they need to be revised or replaced with other test items: the competency achievement indicators and the question indicators that are the same as the three test items. Second, the abilities of students who took the test were grouped into 3 groups, namely high, moderate, and low abilities. Students who have high category abilities in terms of working on HOTS-based physics test items are 18.33%. Students with moderate abilities in working on HOTS-based physics tests on Elasticity and Hooke’s Law, namely as much as 65.00%, while students with low abilities are as many as 16.67%.
