This study aims to determine the effect of using role-playing models on improving critical thinking skills (CTS) and students learning interest on chemical bonding material. The research method used was a quasi-experimental design with pretest posttest control group design. The number of samples used were 135 students majoring science at MAN Banda Aceh, who were selected using purposive sampling technique. The data of this study were obtained from reasoned multiple-choice test questions and student learning interest questionnaires. Data were analyzed using N-gain test, z test and t-test, the results of differences in the increase of CTS in research classes were calculated using Z count >Z table with a significant level of 0.05, while the results of students learning interest in the experimental class obtained t count (5.845) > t table (1.895) with a significant level of 0.05. Based on the results of the study, it can be concluded that the role-playing model implementation can improve the CTS and learning interest in chemical bond concept.
