Abstract

The study objective was to determine the validity and reliability of the test items used to measure understanding of multiple representations. For this purpose, quantitative methods are applied. Participants were first-year students of the Chemistry Department, Education and Teacher Training Faculty, Syiah Kuala University, who took the Basic Chemistry course I (specifically solubility, redox, and hydrocarbons). The test was followed voluntarily. Before determining the validity and reliability of each test, the Multiple Representation Understanding Test (MRUT) was developed, which was conducted in five stages. MRUT contains 20 items, and its validity is determined using Pearson Product Moment (PPM). Valid test items are nine where rcount 0.3128-0.7145. The nine-item tests are reliable, and Cronbach alpha ranged from 0.701 to 0.769 (moderate-high).
