摘要：In this study, it was aimed that is there any effect of 3D computer models on students' academic achievement and three dimensional thinking and spatial ability. The sample of study consist of 67 second year science education students who attended as Experimental and Control Group in which the unit of Structure of Atom, were taught Primary Science Education Department. Study was grounded on semi-experimental design method. As the data collection instruments, Academic Achievement Test (AAT) and Spatial Visualization Test (SVT) were used. The data obtained on instruments were evaluated by using descriptive statistics, compare tests and effect size. The results of the study indicate that 3D computer models are more effective than traditional teaching method on increasing students' academic achievement and improving their and spatial abilities.
