Computer-based application for high school physics exams using IRT model 1P

This research was conducted with aims to develop a computer-based school exam application model for high school physics subjects. The questions that have been developed in the model are then analyzed using IRT Model 1P (Rasch Model). The research method used is Sadiman type of research and development. The product developed is in the form of a test kit application model for School Physics Exams. The developed product shows very good criteria with an average score of 87.79% with details for aspects of Physics material at 87.92% (very good), assessment aspects of 83.13% (very good), and media aspects of 92.32% (very good). The results of the analysis of the problems that have been developed in the model using the Rasch Model analysis show all the questions are declared valid and reliable, so it is feasible to be implemented in the implementation of the School Exams. The questions that have been developed are also scattered in various levels of difficulty and are not biased towards gender and school origin. Based on the results and discussion, the computer-based school exam application model for high school physics subject is appropriate to be used and implemented in the implementation of school exams.
