In this study, the effectivity of jigsaw method, one of the cooperative learning models, on teaching the concepts related to sense organs and their functions to four-five year-old children in nursery class was analyzed. The study is in the semi-experimental design consisting of experimental and control groups and pretest and posttest. The sample of this study consists of 38 children from the nursery class of Ministry of National Education in Agri city center, in 2015-2016 academic years. Two groups determined randomly have been formed. These are: Jigsaw Group (JG, N = 20) and Control Group (CG, N = 18). In the direction of the goals of this study, a data collection tool has been developed by the researcher to collect data. The test prepared by the researcher to determine the knowledge levels of the students about organs like ear, tongue, eye and skin and senses like hearing, smelling, tasting, seeing and sensing has been used. As a result of the obtained data, it has been determined that cooperative learning model is more effective in teaching the sense organs subject to the children compared to the traditional teaching method.
