Lack of student learning outcomes because student are less active in learning and lazy in doing task. It appears from the lack of interaction between teachers and students and between students and students.

The results reflect the first cycle for improvement implemented in the second cycle. So implementation learning in this second cycle is in accordance with the learnig steps planned. Base on the analysis of learning outcomes increase student learning outcomes after study. It can be seen from the increasing number of students who avvieve a Minimum Completeness Critera (KKM) in daily I 70% and daily II 85%. Compared with the base score of 45% thus it can be concluded that the application of learnig model TSTS can improve students mathematics learning outcomes.en-USKoopreative Type Two Stay Two StrayLearning Outcomesstudent Paper Post Degree
