MoIP-ST: An Instrument to Measure Students’ Problem Solving Skills on Momentum and Impulse Astuti, Itsna Rona Wahyu Kaniawati, Ida Samsudin, Achmad Suhendi, Endi Supardiyono, Supardiyono Suparman, Andreas Hegarna, Rona Vera, Rosi This research aims to develop the MoIP-ST (Momentum and Impulse ProblemSolving Test) instrument to measure students' problem-solving abilities according to the stages of problem-solving skills. The research method used is 4). The research participants were 64 students, consisting of 32 rural and 32 urban 10th-grade students in East Java, who were randomly selected. The first analysis is a multi-rater Rasch measurement based on the results of expert validation, which indicates that item I1 needs improvement. The second analysis is the analysis of the MoIP-ST instrument using the Rasch model, which shows that overall the items on the MoIP-ST are valid and reliable with a Cronbach Alpha of 0.87. The third analysis is the use of the MoIP-ST, which shows that the problem-solving ability of rural students is lower than that of urban students. Student problem-solving needs to be improved through models, methods, learning models, and teaching materials that support problem-solving.Keywords: test instrument, problem solving skills, physics learning.
