Abstract:

In this study, the study was conducted in the 6th grade of science. It is intended to develop a valid and reliable success test for the "Cell" subject of the class "Systems in our body" unit.  The success test, taking into account the achievements of the cell subject included in the 6th class Science course curriculum, has been prepared as a already selectively test for 25 items. The test’s pilot study, 2017-2018 educational year 6. There were 62 students who studied in the class. The comprehensibility of prepared test materials, consistency with scientific information, was organized by the opinion of various specialists in the field of science knowledge education. According to the answers the students gave to the materials in the success test, the material analysis was carried out and thus the differentiability and difficulty index for each material were calculated. After the substance analysis, 3 subjects were removed from the test and the Cell Success Test (HBT) was obtained, consisting of 22 questions. The average substance difficulty of HBT is 0.652 and the average substance differentiability is 0.507.

Abstract:

In this study, it is aimed to develop a valid and reliable achievement test for the subject of “Cell” belonging to the 6th grade “Systems in our Body” unit within the scope of Science course. The achievement test was prepared as a 25-item multiple-choice test, considering the cell-related objectives in the 6th grade Science curriculum. The pilot study of the test was carried out with 62 students attending 6th grade in 2017-2018 academic year. The comprehensibility and the consistency with the scientific knowledge of the test items were prepared by the opinions of various experts in the field of science education. The item analysis was performed according to the answers of the students in the achievement test, and the discriminant and difficulty indexes were calculated for each item. After the item analysis, 3 items were excluded from the test and a Cell Achievement Test (CAT) consisting of 22 questions was obtained. The mean item difficulty of CAT was 0.652 and the mean discrimination index was 0.507.
