%X In this study, the effect of models and cooperative learning on particulate level of physical and chemical changes was investigated. Quasi-experimental method pre- and post-test was used. The sample was consisted 71 prospective science teachers. Three research groups (CLG: cooperative learning group, n=24; CLMG: cooperative-model group, n=24; and control group (CG, n=23) were studied. In order to collect data, the Physical and Chemical Changing Test (PCCT) consisting of three open-ended drawing questions was applied as pre- and posttest. For the analysis of data obtained from the PCCT, the Kruskal-Wallis and Mann-Whitney U tests were used and descriptive statistics were used to determine the conceptual understanding. In the pre-test there was not a significant difference among groups. In the post-test, there was a significant difference among research groups. In addition, some prospective science teachers thought the matter as a whole rather than a particulate structure, had a problem in the particulate drawing of solid materials, and had various misconceptions in the concepts of physical and chemical change
