THE DEVELOPMENT OF TWO-TIER MULTIPLE CHOICE TESTS TO ASSESS STUDENT’S CONCEPTUAL UNDERSTANDING IN PHYSICS LEARNING ASSISSTED BY ALGODOO

Physics learning has a relationship between one concept and another. There is an error in a concept, this can affect the understanding of other concepts, resulting in low student learning outcomes. Therefore, assistance is needed to measure student learning outcomes, for example by providing learning tests. This study aims to develop a two-tier multiple-choice test for the concept of "Newton's law of motion" in class XI SMA N 1 Percut Sei Tuan. This research is a development research using the 4D model to produce a product in the form of a two-tier multiple choice test on the material of Newton's law on modified motion without including the dissemination stage, namely: (1) define; (2) design; (3) developing. The final version of the multiple choice test consists of 12 items. The subjects of limited scale tests and broad-scale tests were class XI students of SMA N 1 Percut Sei Tuan in the 2019/2020 academic year. The student has completed a unit on Newton's Laws of motion. The reliability of the test was 0.76. Based on data analysis, ten alternative conceptions were identified. The results showed that a two-tier multiple choice test was effective in determining student misconceptions and could also be used as an alternative to traditional multiple choice tests. In conclusion, a two-tier multiple choice test can be used to assess students 'conceptual understanding as well as students' misconceptions about the concept of Newton's law material about motion.
