Abstract

The aim of this observation is to describe the mathematic learning process which apply TGTcooperative type learning method to increase the mathematic proclivity and achievement ofstudent in class VIII C SMP N 2 Sanden, Bantul. The type of this observation is ClassAction Research (CAR). The Data accumulation technique in this observation usingobservation technique, questionnaire technique, test technique, documentation and range ofactivity record technique. After applied the cooperative type TGT learning method in classVIII C SMP N 2 Sanden, Bantul. The result of the observation indicated that the mathematicproclivity and study achievement of student have been advance. Its indicated by the averagepresentation progress of study proclivity student in pra step amounted 48,66% advance to60,31% at the cycle I and 68,88% at the cycle II. The student mathematic achievement areadvance, according to the average of pra step amounted 71,25 to 77,5 and at the end of cycleI and then 82,5 at the end of cycle II. Whereas the student presentation who get point ≥ 75advance too. Which at pra step amounted 35,71% to 64,29% in cycle I and then 85,71% incycle II. According to the observation teachers have to use TGT cooperative type of learningmethod in mathematic course especially in another material as an alternative to advance thestudent proclivity and study achievement in mathematic learning.

Abstract

The main objective of the study is to describe the learning process by using cooperative learning type STAD (Student Teams Achievement Division) to increase student’s active and learning achievement of mathematics of the seventh grade students of SMP N 5 Cilacap. The hypothesis in this study is learning mathematic by using cooperative learning type STAD (Student Teams Achievement Division) to increase student’s active and  learning achievement of mathematics. This research is Classroom Action Research (CAR), which is done collaboratively. The results of the study showed that after the implementation of learning by using cooperative learning type STAD (Student Teams Achievement Division) there is an increasing activity in learning mathematics. It seen from the percentage increased from 51,74% for the first cycle and the second cycle becomes 78,13%. The averages of mathematics achievement of the students increased from the beginning (pre-cycle) of 62,94 into a 68,75 in the first cycle and the second cycle increased to 75. The result for mastery learning students increased from pre-cycle by 28,13% to 62,5% in the first cycle and the second cycle increased to 68.75%. So it can be said that the cooperative learning type STAD (Student Teams Achievement Division) activity and students' mathematics achievement can be improved.

Abstract

This research intent to know relationship: (1) adversity quotient with learned achievement, (2) self efficacy with learned achievement, (3) study habits with learned achievement, (4) are jointly between adversity quotient, self efficacy and study habits with math learned achievement in tenth grade students of beauty skill program Vocational Middle School at Umbulharjo District. This study was expost facto.  This study population was all student in tenth grade of beauty skill program Vocational Middle School at Umbulharjo District totaling 209 students. The sampling technique used was a cluster random is sampling than sample was 62 students. Technique of data collecting used the technique to measure adversity quotient, self efficacy and study habits, and documentation technique to measure student achievement. The data analysis technique used is the descriptive statistical analysis and correlation analysis. The result showed that: (1) There is a positive and significant relationship between adversity quotient with math learned achievement student with a correlation of 0,352. (2)There is a positive and significant relationship between self efficacy with math learned achievement student with a correlation of 0,466. (3) There is a positive and significant relationship between study habits with math learned achievement student with a correlation of 0,442. (4) Taken together there is a positive relationship between adversity quotient, self efficacy and study habits with math learned achievement student with a correlation of 0,609. Based on these results, it was concluded that students learned achievement is influenced by adversity quotient's factor, self efficacy and study habits.
