The aim of this study was to determine the effect of Student Teams-Achievement Divisions cooperative learning with models on academic achievements of undergraduate university students attending classes in which the electrochemical cells. The sample of research was comprised of 70 students from first class of science teacher education program during the academic year 2014-2015. The data obtained by the Electrochemistry Achievement Test (EcAT). The study was carried out in three different groups. The research groups were randomly assigned as the cooperative learning with models group (CLMG), the cooperative learning group (CLG), and the control group (CG). The data obtained by the instrument was evaluated through descriptive statistics, one-way ANOVA, and ANCOVA. The results indicated that teaching electrochemical cells via STAD with Model method was more effective than the traditional teaching method and only STAD in increasing academic achievement. In addition, according to the EcAT results, students' high levels of misunderstanding show that there are indicative of some deficiencies in teaching of the electrochemical cells in the molecular level.
