Abstract

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 interest  in the first cycle in the mount of 70.18% to 80.76% in the second cycle. The students’ 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 improve  the interest and learning achievement.

Abstract

The purpose of this research is to improve the activity and mathematics achievement of students of class VII with learning methods of problem solving in SMP N 1 Banguntapan. Techniques of data collection in this study was done by observation, documentation, and testing. Test instrument used to test the test item, whereas the observation sheet used to determine the level of involvement of the student. Data analysis techniques for observation sheet was conducted to determine student activity, whereas for mathematics achievement tests done by calculating the average value of the class. The results showed that after the application of the learning methods of problem solving, activity and learning mathematics achievement increased. It can be shown an increase in the average yield percentage of student activity sheets based on the observation student activity first cycle 58.02%, 75% for the second cycle. While the average value of student mathematics achievement increased from an average initial value of 64,34 to 71,99 in the first cycle and second cycle being 80,83. It is expected that schools can apply the learning method.

Abstract

The aim of this research was to describe about teaching learning process using Cooperative Team Assisted Individualization (TAI) to increase student’s active and study result to the VII B grade student’s at SMP Negeri 1 Cilacap. The hypothesis of this research was applying TAI could increase student’s active and student’s study result. This research was Classroom Action Research. The research result showed that after applying TAI 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 65,17 score, increasing in first cycle was 69,33 and increasing second cycle was 78,13. From the result above, it showed that TAI could increase student’s active and study result.

Abstract

This research aims to know the information about the tendency of the mathematics learning achievement and activeness of students in SMP N 2 Tempuran VII grade by snowball throwing and conventional model, to determind which method will give good achievement in mathematics, between cooperative snowball throwing type and the conventional method, to know which the mathematics learning achievement that is better among high, medium, and low activeness, to know the interactions between application of learning model and activeness level. The population of this research was all students of class VII consist of 5 classes in SMP N 2 Tempuran 2013/2014. The research sample of 2 classes was taken by cluster sampling technique. The data analysis uses descriptive analysis and two-way ANAVA analysis. The results of the analysis in the research are: 1) the mathematics learning achievement of class experiment is very high (), (2) the mathematics learning achievement of class control is high (, (3) the activeness of class experiment is moderate (), (4) The activeness of class control is low (), (5) Class experiment has better learning achievement than class control (= 4.5386), (6) the mathematics learning achievement of students who have high activeness is better than students who have moderate activeness, the mathematics learning achievement of students who have moderate activeness is better than students who have low activeness, the mathematics learning achievement of students who have high activeness is better than students who have low activeness (= 9.94245), (7) There is no interaction between learning model and activeness level of students based on the mathematics learning achievement of students.

Abstract

The research purposes to increases and mathematics achievement with Verbal Football method in class VII A SMP Negeri 2 Sanden Bantul. The research subjects were students of class VII A SMP Negeri 2 Sanden and object of this research were interests and mathematics achievement. The results showed that interest and mathematics achievement increase. The results can be seen from questionnaire data pre-term by 72.79% with moderate category, increased to 76.89% with the high category in first term. Then increased again to 82.42% in second term with the very high category. The results of mathematics achievement obtained from test, with percentage completeness obtained pre-term 61.29% with an average of 69.51. In first term increased to 80.65% with an average of 78.87 and in second term increased to 100% with average value of 91.45.
