ABSTRAK

Ability understanding mathematical concepts is one of the important goals in mathematics, giving the sense that the material taught to students not just as rote, but he point to students' understanding. This study aims at understanding the concept of descriptive mathematical ability of students based on categories with cooperative learning model jigsaw. This study aims at understanding the concept of descriptive capability of this type is deskrispsi qualitative research. Damati Subjects in this study were the students of SMA 6 Bengkulu city. With the number of students in class that there was a total of 33 students with 17 female students and 16 male students. This study was carried out in conjunction on 22 May 2014 until 31 May 2014. The results of this study are descriptive ability of understanding the concept of students using cooperative learning model jigsaw seen each category of student understanding of the concept that the ability of high, medium, and low. With the number of students who are in the high category 8 students, there are 19 categories of students, and in the lower categories are 6 students. Judging from the number of students in a category is the highest available. The students who are in the category of students in general are able to answer correctly, even though there are still errors in the answer.

Kata Kunci: concept comprehension abilities, learning model jigsaw.

Abstract

Lesson study is an education program from Japan which is developed in Indonesia to improve quality of education in Indonesia. It is held by a team which works collaborativly. Members of the team share their knowledge and experience to increase the quality of learning process. This study describe mathematics communication ability of student who is candidate of mathematics teacher. By lesson study in Mathematics Education Program in Muhammadiyah University of Bengkulu, the mathematics communication ability of student can improve.

ABSTRACT

Based on the previous observasion done by the researcher at FKIP of Muhammadiyah University Bengkulu, the researcher found that student’s ability in thinking creatively was still low. It was assumed that the lecturer-centered learning approach applied was one of the causes of this problem. One of the efforts tried to solve this was by applying open-ended approach. The aims of this research were to know and reveal the difference between creative thinking ability of the students who were taught by using open-ended approach and those who were taught by using conventional approach.This was a quasi experimental research which was conducted to the fourth semester students who took Linier Program subject in Academic Year 2011/2012. The sample was taken by using random sampling technique. The data of this research was collected through a test, observasion sheet and interview. The data gotten was analyzed. The result of the research showed that the creative thinking ability of the students who were taught by using open-ended approach was higher than those who were taught by using conventional approach.

Abstract

This study has a back ground of concerns about the ability of students' mathematical connection is still low, it is shown from the results of the initial test(pre-test) students in class VIIB Junior High School 09 Mukomuko. This study aims to improve the ability of mathematical connection sthrough generative learning model. This research is Classroom Action Research (CAR). This research was conducted as two cycles with research subjects are 32 students which consist of 17 male students and 15 female students. The instruments used were: 1) teacher observation sheet, 2) student observation sheet, 3) test the ability of mathematical connections. Data were analyzed descriptively. This study showed increased activity after learning of teacher sand students performed at each cycle, and to the ability of mathematical connections also increased, it is shown from the results of the test(post-test) on the second cycle and each indicator has achieved success criteria. Thus, it can be concluded that the generative models can improve students' mathematical connections.
