Abstract

A good test is one that has been validated and the accuracy of the gauge is tested. This article aims to provide a study of the implementation of item response theory with the Rasch model to analyze the quality of the final exam test items in physics. This is a survey conducted once and at a time. The subjects were the 131 grade XI students of MAN 1 Bone. Test of final exam and documentation of physics learning were used as data collection techniques. The data analysis method used was the item response analysis with the Rasch model. The results showed that the reliability value with Cronbach alpha (KR-20) which measures the interaction between the person and the item as a whole, namely α = 0.47. The value of person reliability is 0.48 and the value of the item reliability is 0.88. This shows that the consistency of the answers from the test takers is still weak, but the quality of the items in the reliability aspect of the instrument is quite good. So that the questions final exam test in physics subject still needs improvement and consideration to be used again in the future.
