Abstract
This study aims to determine how the effect of the Collaborative Teamwork Learning Model on Work and Energy Matter Based of Multi Representations on Physics Learning Outcomes. The research method used is a quantitative research method with None Quivalent Control Group Design research design. The sampling technique used was purposive sampling. The sample used was 25 students in each class, both the experimental class and the control class. The instrument used was an essay instrument based on multi-representation as many as 5 questions that had passed the validity, reliability, difficulty level, and distinguishing power. The results of this study were tested using the z-test because the data were not normally distributed but homogeneous. Based on the calculation, the value of or -1.79 < -1.96 is obtained so that it can be concluded that there is a significant effect of the Collaborative Teamwork Learning Model on business material and energy based on Multi Representation on Physics Learning Outcomes. This is also supported by an increase in student learning outcomes using a higher Multi Representation-based Collaborative Teamwork Learning model. This happens because when the learning process takes place students are more active in discussing both group discussions and class discussions and students are also more enthusiastic about learning physics concepts which are represented in several forms of representation by educators.
