The purpose of this research to determine whether cooperative learning model through the use of snowball throwing prized chart is more effective than conventional learning model to mathematics learning outcomes seventh grade students of SMP Negeri 11 Yogyakarta.Â The population consisted of 137 students were divided into four classes. The sample selection is in this study using cluster random sampling technique. Data analysis techniques in this study using t-test, and than compares tobservatedÂ with ttable, with df = n1 + n2 -2, and Î± = 5%. If tobservatedÂ Â ttable , then Ho is refused, meaning that the average score of the achievement of the experimental classes are better than the average score of the achievement of the control class. The research is found that the average achievement scores (gain) = 4.64 and the experimental class average achievement scores (gain) control class = 3.48. Obtained with Â and Â tobservated = 2,214 > ttable = 1,645 then Ho is refused, it means the average achievement scores (gain) achievement test on the subject of rectangular and square in the experimental classes are better than the control class. So it can be concluded that the cooperative learning model through the use of snowball throwing prized chart is more effective than conventional learning model to mathematics learning outcomes seventh grade students of SMP Negeri 11 Yogyakarta.

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 result of the study showed that the studentsâ€™ motivation and achievement could be increased through Self Regulation Learning Strategy. It was proved by the improvement of average questionnaireâ€™s score of the studentsâ€™ motivation from 59.26% in pre-cycle to 68.62% in cycle I and then 84.54% in cycle II. The learning achievement was also increased which could be seen from the average score from 61.429 in pre-cycle to 66.905 in cycle I and 79.911 in cycle II. Moreover, the studentsâ€™ KKM score (70) was also increased from 35.71%Â in pre-cycle to 60.71% in cycle I and 79.91 in cycle II. It was suggested that mathematics teachers could apply this effective strategy in their teaching and learning process.
