Abstract
This study aims to analyze the validity and reliability of the algebraic reasoning question instrument. The total number of questions in this study were 8 questions which were done by 107 junior high school students in Indonesia. Based on the results of the analysis using the Rasch model, it was found that the instrument had Cronbach’s alpha (KR-20) in the medium category, the item reliability was excellent, and the person reliability was in the low category. This shows that the instrument is a very reliable instrument for assessing students’ algebraic reasoning but students were unable to solve them well. Meanwhile, the results of the validity found that Q8 was not the fit criteria for MNSQ Outfit, ZSTD Outfit, and PTMEA-CORR. As for person fit, only six students showed a misfit, which indicated that other students gave a meaningful response to Rasch’s analysis.
