Abstract

This research aims investigate the effect of Numbered Head Together (NHT) learning model towards students’achievement in learning mathematics based on students’ learning habit to the eighth grade students of SMP N 12 Yogyakarta in academic year 2013/2014. The population of this research was eighth grade student of   SMP N 12 Yogyakarta which consist of 5 classes. The sample of the research was 2 classes which were taken by cluster sampling technique. The data were collected by using students’ learning achievement and questionnaire of learning habit. The data were analyzed by using two-way analysis of variance. The result of the research shows that (1) the students’ learning achievement who are taught using Numbered Head Together (NHT) learning model has  same achievement as the students who are taught using conventional learning model, (2) the students’ learning achievement who have good habit in learning mathematics are better that the students who are not have it, (3) students’ achievement who have good learning habit in learning mathematics and are taught by using conventional learning model are better than the student who are taught by using Numbered Head Together learning model, (4) students’ achievement who have no good learning habit in mathematics and are taught by using Numbered Head Together learning model are better than the student who are taught by using conventional learning model, (5) student’ achievement in mathematics who are taught by using Head Together learning model and have good learning habit are better than the student who have no good learning habit, (6) student’ achievement in mathematics who are taught by using conventional learning model and have good learning habit are better than the student who have no good learning habit.

Abstract

The general objectives of this research are: (1) cooperative learning model is more effective to use between TGT and NHT, (2) the effect learning activity to student’s achievement, (3) there is an interaction between learning models and learning activity to learning achievement of mathematics. This is a quasi-experimental research.  The research populations are the seven grade of SMP 9 Yogyakarta in Academic Year 2013/2014. Samples are taken with cluster random sampling technique obtained experimental class I and experimental class II. The data were obtained through test and questionnaire. The test instrument used test of item validity and test of reliability. In the analysis of data, the researcher used two-way analysis of variance test for using requirements analysis are normality and homogeneity tests. The results show that the value of FA = 24.364 > Ftable  = 4.00; FB = 209.683 >  Ftable = 3.15; and FAB = 0.664 <  Ftable = 3.15 which means that all of the hypotheses are accepted.  The result of the study showed TGT is more effective to be used than NHT, high learning activities give the best achievement of mathematics means that learning activities will give an effect to the students’ achievement, there is no interaction between learning model and learning activity on the learning achievement of mathematics means that on each learning activity levels (high, medium, low) mathematics achievement of TGT is always better than NHT, as well as on each learning model (TGT, NHT) mathematics achievement of high learning activities is always better than mathematics achievement of medium and low learning activity.

Abstract

the purpose of this research is to increase interest and achievement of learning Mathematics with Contextual learning in grade students of SMA XG Wangon school year 2013/2014 . This research is Classroom Action Research (CAR).The subjects in this study were grade students of SMA XG Wangon totaling 28 students , while the application of contextual learning object is to increase interest and achievement of learning Mathematics. The results showed that after the application of contextual learning , interests and learning achievement of students has increased. This can be shown by an increase in the percentage average student interest from 52.33 % to 80.98 % pre-action into the after action. Learning achievement of students also increased , judging from the average value of 62.85 into 70.35 in pre-cycle at the end of the first cycle , and increased again at the end of the second cycle becomes 84.28. While the percentage of completeness students ( with KKM 75 ) also increased , namely the pre-action by 25 % to 67.85 % in the first cycle , increased again in the second cycle becomes 85.71 %. Can be inferred contextual learning can increase interest and achievement of students learning mathematics.
