This research aims reveal: (1) the vertical equating equation of a test instrument, and (2) the development of physics competence among grade X and XI students of senior high school. This study used the quantitative descriptive method. The population is the students of senior high schools in Purworejo district. The data are in the form of the students' responses to the reasoning ability tests on the physics subject. The research sample was established using the stratified proportional random sampling technique, consisting of 352 grade X students and 352 grade XI students. The instruments are two sets of physics tests in the form of objective tests with five alternative answer and using an anchor of 25%. The data are in the form of a processed partition and equated using common item non-equivalent groups' designs with mean & sigma equating methods based on the model of Rasch item theory. The research concluded that (1) the results of the vertical equation based on the Rasch model show that the equation for transition from type X to type XI is b * =bx -0.36; (2) there is an increase in the physical ability of students from grade X to grade XI or the ability of grade XI students is higher than that of grade X. The conclusion of this study can be used as an input for teachers. Improving themselves concerning the teaching that has been done and the achievement that has been made by paying attention to appropriate learning methods and student motivation to improve student physics learning achievement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
