Abstract

Physics deals with a lot of quantities that have size and direction and thus require a mathematical representation to describe it. So that in the context of physics learning cannot be separated from the application of mathematical representation. This research aims to: 1) determine the feasibility of assessment instruments by conducting content validation; 2) find out the quality of grading instruments by conducting empirical validation. The test development stage includes: 1) test planning, 2) test trials, and 3) revision and assembly of tests. This assessment instrument contains particle dynamics, the laws of planetary motion and work and energy at the senior high school level. The assessment instrument was developed based on three components of mathematical representation ability. The results of this study are: 1) the results of the content validation data analysis show 39 items of the test items are valid and worth testing; and 2) the results of the empirical validation data analysis are shown from three item characteristics, namely: a) the results of the validity test show that the 39 developed test items are fit with the PCM model with the average INFIT MNSQ items are 1.00 and the standard deviation is 0.09, so all questions are valid; b) the reliability value is 0.46, so the reliability of the questions belongs to the poor category and the test is suitable for students with abilities, -1.7 ≤ θ < 3.6; and c) the difficulty value of all items is in the interval -1.28 and 1.23, so that the quality of all items is categorized as good.
