The purpose of this research is to describe the results of the implementation of the think pair share model on optical concepts that includes cognitive, affective, psychomotor learning outcomes and student responses. The type of this research is descriptive research. This research was conducted in class VIII THB Junior High School, Bekasi. The research design used was one group pretest-posttest design. Data collection techniques used were observation, tests, and student response questionnaires. The analysis technique of the research results used is quantitative descriptive analysis including the calculation of proportions and percentages. Based on the results of data analysis, cognitive, affective, and psychomotor learning outcomes are achieved with an average achievement of the cognitive proportion of 0.85, affective proportion through observation of 0.83, and the proportion of psychomotor through a portfolio of 0.82. Student responses to the implementation of learning by implementing a think pair share model that includes five aspects are very good, with an average percentage of the five aspects is 90.53%. Based on the data above, it can be concluded that the implementation of the think pair share model can improve students’ physics learning outcomes.
