Abstract

Abstract: The aims of this research is to describe the level of Junior High School students’ creativity in solving divergent mathematical problem viewed from the students’ learning style.This study was qualitative descriptive reasearch. The subject of this research was 9 students from the ninth grade of MTSN Plupuh consisting of 4 students had visual learning style, 3 students had auditorial learning style, and 2 students had kinesthetic learning style. The researcher used purposive sampling and snowball method to select the subject. In collecting data, the researcher used grouping test in learning style, problem solving test of divergent mathematics, and interview. To techniques of data analysis in this research were as follows: (1) reducing data, (2) present of data in narrative text, (3) To conclude the level of students’ creativity at each learning style. The validity of data used time triangulation.Based on the research result, there are two findings as follows: main findings and other findings. The main findings shows that (1) the students with visual and auditorial learning styles can eligible to indicators of creativity, fluently and flexibility, so that those students have the third level of creativity (creative) in solving divergent mathematical problem, (2) While, the students with kinesthetic learning style can eligible to indicators of creativity, namely fluently. So that those students have the first level of creativity (less creative) in solving divergent mathematical problem. Then, the other findings data shows that (1) there are two students with visual learning style are identified having the second level (quite creative) and the forth level (very creative) of creativity in solving divergent mathematical problem, (2) while there is one student with auditorial learning style is identified not creative (level 0). Based on the findings, it can be concluded that the students’ learning styles affect to students’ creativity, so that the teacher should know and understand students’ learning style in order to determine the best method of learning process. It is because each learning style affects to students’ different responses in getting the information.Keywords : Level of Creativity, Problem Solving, Divergent Mathematics, Students’ Learning Style

Abstract. The aims of the research were to determine: (1) which one has better learning achievement, Jigsaw learning model, TGT, or conventional, (2) which one has better learning achievement, students with high, middle or low intrapersonal, (3) based on learning model, which one has better learning achievement, students with high, middle, or low intrapersonal intelligence, (4) based on intrapersonal intelligence, which one has better learning achievement, Jigsaw learning model, TGT, or conventional. The type of the research was a quasi-experimental research with  a 3 x 3 factorial design. The population was XI science  students  of Senior High School in Kudus regency on academic year 2013/2014. Sampling was done by stratified cluster random sampling. The size of the sample were 277 students consisted of 95 students in the first experimental group, 87 students in the second and 95 for the control class. The instruments used were mathematics  achievement test and  intrapersonal intelligence questionnaire. The hypotheses testing used unbalanced two ways ANOVA. Based on hypothesis testing, it can be concluded as follow. (1) Student learning achievement  treated by TGT  is better than Jigsaw  and conventional, and Jigsaw model is better than conventional, (2) Learning achievement of students who have high intrapersonal intelligence is better than students who have middle and low intrapersonal intelligence, and students who have middle intrapersonal intelligence is better than students who have low intrapersonal intelligence, (3) Based on  all types of learning models,    students who have high intrapersonal intelligence have better learning achievement than students who have middle and low intrapersonal intelligence, and students who have  middle intrapersonal intelligence have better learning achievement than student  who have low intrapersonal intelligence. (4)  For high intrapersonal intelligence, students learning achievement treated by TGT is better than Jigsaw, for both learning models,  Jigsaw  and conventional have the same learning achievement. For middle intrapersonal intelligence, students learning achievement treated by TGT  is better than conventional, while both learning models,  Jigsaw and conventional have the same learning achievement. For low intrapersonal intelligence,  conventional and TGT are better than Jigsaw, while both learning models, TGT and conventional have the same learning achievement.Keywords: Jigsaw, TGT,  intrapersonal intelligence, learning achievement.

Abstract

Abstract: The aim of the research was to determine the effect of learning models on mathematics achievement viewed from the students attitude towards mathematics. The learning model compared were 4Ex2, LC 5E and conventional learning model. Data analysis techniques used to test the hypothesis was two-way analysis of variance with unbalanced cells. The conclusions of the research were as follows. 1) The learning achievement in Mathematics of the students exposed to the 4Ex2 learning model are better than LC 5E learning model and conventional learning model, and  the learning achievement in Mathematics of the students exposed to the LC 5E learning model are better than conventional learning model. 2) The learning achievement in Mathematics of the students with the high attitudes toward Mathematics are better than that of the students with the medium and low attitudes toward Mathematics, and the learning achievement in Mathematics of the students with the medium attitudes toward Mathematics are better than that of the students with the low attitudes toward Mathematics. 3) In the 4Ex2 learning model, the learning achievement in Mathematics of the students with the high attitudes toward Mathematics are better than medium and low attitudes toward Mathematics, and the learning achievement in Mathematics of the students with the medium attitudes toward Mathematics are better than low attitudes toward Mathematics. In the LC 5E learning model, the learning achievement in Mathematics of the students with the high attitudes toward Mathematics are better than medium and low attitudes toward Mathematics, the learning achievement in Mathematics of the students with the medium attitudes toward Mathematics are the same as low attitudes toward Mathematics. In the conventional learning model, the learning achievement in Mathematics of the students with the high attitudes toward Mathematics are the same as medium attitudes toward Mathematics, the learning achievement in Mathematics of the students with the high and medium attitudes toward Mathematics are better than low attitudes toward Mathematics. 4) In the students with the high attitudes toward Mathematics the learning achivement of the students exposed to the LC 5E learning model are the same as 4Ex2 learning model and the conventional learning model, the learning achievement in Mathematics of the students exposed to the 4Ex2 learning model are better than conventional learning model, and both in the students with the medium attitudes toward Mathematics and in those with the low attitudes toward Mathematics, students exposed to the 4Ex2 learning model, LC 5E learning model, and conventional learning model result in the same learning achievement in Mathematics.Keywords: Learning model, 4Ex2, LC 5E, attitudes toward Mathematics, learning achievement in Mathematics.
