Abstract
The aim of this research is to develop Physics problems that are appropriate to be used for the final assessment at the level of the High School Education unit in Physics with the Rasch Model analysis. Research method used in this study is Research and Development with the ADDIE model. Physics problems developed refers to the USBN problem grid issued by the Badan Standar Nasional Pendidikan (BSNP). Problems that have been developed will be validated by Physics experts, then tested on students, and analyzed for their quality using Rasch Model analysis. Validation results from Physics experts gave a score of 86.25% with very good criteria, it shows that Physics problems are feasible in terms of Physics material. The problems that have gone through the validation stage are then tested to several students and analyzed using the Rasch Model. Results of the analysis show that problems that have been developed have good validity and reliability. Problems that have been developed also have varying degrees of difficulty, from very easy to very difficult. Results of this analysis also show that problems that have been developed are not biased towards a particular group. Another thing obtained from the analysis using the Rasch Model is that students who carry out this test have consistent answers. Based on the results of the study, it can be concluded that Physics problems that have been developed are appropriate to be used for the final assessment at the level of High School education unit in Physics lesson.
