Efforts to Improve Student Learning Outcomes through Cooperative Learning Based on Team Assisted Individually (TAI)

The purpose of this research is to know the difficulties faced by students in studying the subject of cubes and beams. This study also aims to determine the improvement of student learning outcomes after the implementation of cooperative learning model type based on Team Assisted Individually (TAI). This type of research is classroom action research. In this study divided into two cycles. Before being given an action, the average initial student test result is 66.75 with 55% classical completeness. After given cooperative learning type TAI, the average test result of student's learning I was 76, 75 with 77, 50% classical completeness. And after the second action is given in cycle II, obtained the average value of the test results of learning II 82.775 with classical completeness of 87.50%. Based on the result of the research, it is found that through learning Cooperative Learning Type Team Assisted Individually (TAI) can improve student learning outcomes on the subject of cube and beam.
