This research aims at knowing that cooperative learning model type talking stick with discovery learning appoarch is more effective than conventional learning model toward the result of mathematics subject of the students grade VIII SMP Negeri 11 Yogyakarta. This research uses Pretest-Posttest Control Group Design. The research has two variables. The independent variable consists of cooperative learning model type talking stick with discovery learning approach and conventional learning model, and the dependent variable is result of mathematics subject. The population was all students grade VIII in SMP N 11 Yogyakarta consisting of 136 students in 4 classes. The research sample of two classes was taken by cluster random sampling technique. Data collection technique uses pretest and posttest. The data analysis uses t-test, in which it was previously tested using pre-requisite test, namely; normality test and homogenity test, and than compares testimatedÂ with ttable, with df = n1 + n2 -2, and Î± = 5%. If testimated Â Â ttable , then Ho is refused. This means that the average gain score of experiment class is better than the average gain score of control class.Based on the result of estimated gained-score it is known that the value of testimated = 2,351, whereas ttable = 1,671. Because testimated = 2,351 > ttable = 1,671, then Ho is refused. This means that the average gain score of experiment class is better than the average gain score of control class. Therefore, it can be concluded that cooperative learning model type talking stick with discovery learning appoarch is more effective than conventional learning model toward result of math subject of the students grade VIII SMP Negeri 11 Yogyakarta.

The purpose of this research was to describe the type cooperative learning mind mapping in improving the interest and learning achievement math of class VIII F SMP Negeri 15 Yogyakarta. The type of this research is a classroom action research. Subject in this study were students of class VIII F SMP Negeri 15 Yogyakarta, there are 34 students. The objective of this research is the interest and learning achievement using cooperative learning in mind mapping model. The results of this research showed that after application of the learning model, the interest and learning achievement were increased. The percentage of students interestÂ in the first cycle in the mount of 70.18% to 80.76% in the second cycle. The studentsâ€™ math learning achievement also be increased can be seen of the average percentage of the initial capabilities of students in the first cycle 63,02 to 72,73 and the second cycle of the percentage becomes 78.71. Thus, advised teachers to implement cooperative learning model of mind mapping to improveÂ the interest and learning achievement.

The purpose of this study was to describe the process of learning by methods Contextual Teaching Learning (CTL) , increase interest and learning mathematics class VII C SMP Negeri 2 Kalibawang Kulon Progo. Hypothesis action in this study is through the implementation of cooperative learning approach can enhance CTL interest and learning outcomes. This research a Classroom Action Research (CAR) or Classroom Action research (CAR) conducted collaborative. The research suggests that increased student interest in each cycle by using learning methods Contextual Teaching Learning (CTL) compared to interest student learning before this research. Before this action student interest is the percentage of 32 % is included in the less qualified, student interest after the first cycle was 57 % qualify as moderate, while the students' interest after the second cycle was 79 % including higher qualifications. prior research These students passively listening to the teacher but after more research students actively ask questions and discuss the students' scores increased, the first score of 55.80 , an increase in the first cycle was 68.54 and increase the second cycle was 72.0. From the above results it shows that the model of learning Contextual Teaching Learning (CTL) may increase interest and student learning outcomes.
