Abstract
This research aimed to develop a valid and reliable scientific process skill test for 60-72 months old preschool children. The study group of the research consisted of a total of 241 preschool children, including 114 preschool children in the pre-pilot application and 127 preschool children in the pilot application. 36 questions were prepared regarding scientific process skills. Test items were prepared with 3 options. The item visualized the options according to the level of the children. The prepared questions were presented to the opinion of two academicians who are experts in the field of science education and three preschool teachers. According to the expert opinions received, two items were excluded from the test. A preliminary pilot application was conducted with 114 preschool children with the remaining 34 items. Six items were removed from the test after pre-pilot application. A pilot application was made to 127 preschool children with the remaining 28 items. Three items were removed after the pilot application. As a result of the pilot application, the KR-20 reliability coefficient of the test was calculated as 0.786. The final version of the test was arranged to consist of 25 items. These results indicate that the test is highly reliable, meaning that the test results accurately reflect the measured property and are reproducible..
