Abstract:

Purpose of this study was to develop a valid and reliable achievement test for the 7th grade “Force and Energy” chapter within the framework of the science course, 2018 curriculum. For this purpose, 34 multiple-choice items were prepared whereby the information in the learning outcomes in the force and energy chapter in the curriculum would be measured mostly with high-level cognitive processes. The application study of the test was conducted with 144 students studying in the 2018-2019 academic year. Necessary corrections were made based on opinions of field experts to establish clarity of the test items, sufficiency of time, and scientific accuracy of the information in the items. Item discrimination and item difficulty indices for each item were calculated according to the answers collected after the application of the test. After the item analysis, 12 items were removed from the test and the Force and Energy Achievement Test including 22 questions was prepared. The mean item difficulty of the Force and Energy Achievement Test was calculated as 0.41 and the mean item discrimination as 0.39.
