Abstract

This research aimed to reveal: (1) the items characteristics of mathematics test and the test information function, (2) identify the function of distractors in mathematics test items based on Rasch models. This study is an exploratory study with a quantitative approach. Data collection technique used in this research was documentation of student answer response at the mathematics achievement test. Analysis of item characteristics and distractors used item response theory of Rasch model. The analysis was performed by using program WINSTEP 3.73. Result of analysis shows that the reliability index .82, from 40 items used there are three items that do not fit, The mathematics test had a good information function and was suitable for measuring students with moderate ability, with the maximum information function obtained at 7.589 logit with a standard error of measurement of .363 on the ability (θ) .00.From 40 items of mathematics test that were analyzed, 10 of it have dysfunction and 8 of it should be confirmed toward the key answer as they are backlashing the theory. Overall the measurement results with the Rash model obtained that 45% of the distractors did not function effectively. The distractors on the test items did not function effectively because they were selected more by groups with high abilities than by groups with low abilities.
