Abstract

The quality of learning activities can be determined by the result of assessment. The measuring tool used in the assessment activity is in the form of a test. This study aims to determine the quality of a test for diagrams and mathematical representation ability of High School students in Physics. This research is quantitative descriptive. There are two sets of test that are set A and B, which is each set test consist of 10 items with 20% of the being an anchor items. Test instrument tested to 317 High School students in Physics in Yogyakarta with purposive sampling. Students’ response data was analyzed based on the items response theory using Partial Credit Model (PCM). PCM is the development of 1-PL model (Rasch model) which contains one parameter item that is the item difficulty level. The results of test quality analysis show that: (1) items test instrument fit with PCM, (2) item difficulty levels are in the range of values -1.023 to +1.785 which includes the criteria of the good items, (3) the ability of respondents who do the test is in the range of values from -1.9678 to +2.0384, and (4) this test is more appropriate for measuring respondents who have value ability -1.85 +1.9. Therefore, this test can be used to measure diagrams and mathematical representation ability of High School students in Physics.
