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. 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 tobservated with ttable, with df = n1 + n2 -2, and α = 5%. If tobservated  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  and  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 testimated with ttable, with df = n1 + n2 -2, and α = 5%. If testimated   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 purposes of this research were to know the achievement of tendency and learning mathematics desire seventh grade students of junior high school in SMP Muhammadiyah 1 Wonosari use cooperative learning model that conclude STAD and TAI types, to know which one the most effective. The type of this research was quasi experiment research. The population of this research was seventh grade students of SMP Muhammadiyah 1 Wonosari academic year 2013/2014. The data that will be analyzed were two classes’ amount 73 students. The data were collected by cluster random sampling technique with drawing way. The data collecting technique were using test and questionnaire technique. Experiment analysis instrument was done usefully include validity, different power, level of difficulties and reliability test. The data analysis technique was descriptive and hypothesis test that done by due diligent test. The result of this research can conclude that: Mathematics learning achievement of STAD students experiment was categorized as medium, mathematics achievement of TAI students experiment was high categorized; Mathematics learning desire of STAD students experiment was high categorized, mathematics learning desire of TAI students experiments was high categorized; Based on mathematics learning of students, TAI experiment group have higher achievement than STAD experiment group therefore cooperative learning model TAI type more effective that cooperative learning STAD type. TAI experiment group have higher mathematics learning desire than STAD experiment group, so cooperative learning model TAI type more effective that cooperative learning model STAD type, it can seen from learning mathematic desire of students.
 
This study aims to find out the effectiveness of TAI model through mathematics learning outcomes in terms of students' student activity. This research was a quasi-experimental research. Sampling technique in this research used Cluster Random Sampling technique. Data collection technique used questionnaire and tests. The data analysis technique used two-way variance analysis with unequal cell. The result of this research was that learning using TAI model is not more effective to use (Fobs< Ftable) with 2.859 <4.00; Students who have high student activity, have mathematics learning outcomes that are no better than those with moderate and low-skilled students (Fobs< Ftable) with 0.5576 < 3.15; There is no interaction between the learning model used and the student activity to the students' mathematics learning outcomes (Fobs< Ftable= 0.44 <3.15).
