Abstract:

The aim of this study is to develop a success test for the science program curriculum gains in 7th grade “Solar System and Beyond: Space Puzzle” unit. For this purpose, 31 questions were prepared in accordance with the unit gains and by using the literature. For the validity of the scope of the test, a table of specifications was created and expert opinions were obtained. The 31-question astronomy achievement test was applied as a pilot study to 150 7th grade students in 2017-2018 academic year. Item discrimination and difficulty indexes were calculated by item analysis. As a result of the analyzes, some questions were corrected and some questions were removed and the number of questions in the test was reduced to 27. After the pilot application, the success test consisting of 27 multiple choice questions was re-applied to 150 seventh grade students as a result of validity and reliability studies. The average item discrimination index of the astronomy achievement test was .38 and the average item difficulty index was .60. Cronbach alpha reliability coefficient of the final test was calculated as .752.The results showed that a valid and reliable test for the 7th grade astronomy was developed with a 27-question four-choice multiple choice test. This test can be used by researchers in the field of science education.
