<![CDATA[The problem has become inseparable in people's lives. Problems can not be viewed as the only burden the man alone, but instead should be viewed as a means to bring new discoveries. Problem solving is central in mathematics. This is because the troubleshooting is close to everyday life, as well as problem solving involves thinking optimally. How to solve a problem can use Polya steps, namely: (1) understand the problem, (2) make a plan troubleshooting, (3) make a plan, and (4) check the answers]]>

<![CDATA[the aim of this research was to describe about teaching learning process using Cooperative Think Pair Share (TPS) to increase student’s active and study result to the VIIIB grade student’s at Taman Dewasa Ibu Pawiyatan Yogyakarta. The hypothesis of this research was applying Cooperative Think Pair Share (TPS) could increase student’s active and student’s study result. This research was Classroom Action Research (CAR) collaboratively. The research result showed that after applying Cooperative Think Pair Share (TPS) in teaching learning process, the student’s active increasing. Before this research the students were passive to listen to the teacher’s explanation but after this research the students were more active to ask and discuss in group. Means student’s score increased, first 53,07 score, increasing in first cycle was 64,86 and increasing second cycle was 74,65. From the result above, it showed that Cooperative Think Pair Share (TPS) could increase student’s active and study result.]]>

<![CDATA[The purpose of this research was to improve the interests and learning outcomes in mathematic of student of class VIII B MTs N Pundong using learning type Make a Match. The subjects of this research was student of class VIII B MTs N Pundong totaling 19 student. The object of this research was interests and mathematic learning outcome. The results showed that after application of cooperative learning model to Make a Match, interests and learning Mathematics has increased. This is indicated by an increase in the average yield percentage interest of each student's learning cycle, namely the pre-cycle percentage interest of 57.95%, in the first cycle of 69.01% and 85.50% for the second cycle. In addition the average mathematics student learning outcomes is increased in precycle for 60.84 increased to 70.21 in the first cycle and second cycle becomes 78.32. As for mastery learning increased from pre-cycle by 52.63% to 63.16% in the first cycle and became 78.95% in the second cycle. Given the cooperative learning model to Make a Match can increase interest and Mathematics student learning outcomes, teachers are expected to implement the learning model in the learning process.]]>
