This research is an experimental research which aims to describe the effectiveness of the methaporical thinking approach to improve the mathematical representation ability of class VIII SMPN 2 Toari. In addition, it also aims to determine how much students are engaged in the learning process when applying the methaporical thinking approach. The research subjects were divided into two groups, namely the experimental group taught using the methaporical thinking approach and the control group taught by conventional learning. The results showed that students who were taught with a methaporiical thinking approach were more active in the learning process so that the ability of representation also increased. In addition, it was found that mean of mathematical representation ability of students taught using the approach of methaporical thinking was better than students taught with conventional learning. Therefore, the approach of methaporical thinking is able to improve the mathematical representation ability of class VIII SMPN 2 Toari

This research is a qualitative descriptive study that aims to describe the misconceptions of junior high school students on the material of flat shapes especially geometry of rectangular flat shapes. The subjects of this study were three students who had the most misconceptions from all students in the class. Students' misconceptions in this study were analyzed using a written misconception test with the CRI (Certainty of Response Index) method and continued with interviews to find out the cause of the misconceptions that occurred. Based on the results of data analysis the three subjects showed almost the same misconception. The first misconception experienced by students on rectangular flat figure material lies in the definition of rectangular flat figure. Students' misconceptions in defining lie in a flat shape that has the same side of length, four corners, and two diagonals that form a right angle. This shows that students only choose rectangular regular shapes. In addition, students also experience misconceptions in distinguishing between sides and ribs. The second misconception, lies in the concept of the properties of a rectangular flat shape especially rectangular. Students assume that the rectangle always has an elongated shape without regard to its properties. Furthermore, there is a misconception when showing another wake. Students assume that the ladder is an oblique rectangle. In addition, if a rectangle has a different position or irregular shape then it is not called a rectangle. The cause of the misconception that occurs is the ability to understand the concepts and images given to the problem

The research aimed at describing the Effectiveness of Experiences, Language, Picture, Symbols, and Application (ELPSA) on Cooperative Setting of Students Teams Achievement Division (STAD) Type in Mathematics Subjects on class X SMP Negeri 29 Bulukumba. The populations of this research were all students of grade class X SMP Negeri 29 Bulukumba and choose one class as the sample of the research by using simple random sampling as the experiment class, clas VII A, was given the treatment of Experiences, Language, Picture, Symbol, and Apllication (ELPSA) Cooperative Setting on STAD type. The data collections consisted of the data of learning model implementation, data of students’ activities, in learning process, data of students’ response on learning instruments, and data of students’ learning result which consisted of the pretest and posttest scores. The data of learning model implementation, students’ activities, and students’ response data were analyzed by using statistic descriptive analysis; whereas, mathematics learning result os students was analyzed by employing statistics descriptive and statistics inferential analysis. The results of the research revealed that (1) the average score of learning implementation level (TKP) was in good criteria (3.50 ≤ x ≤ 4.50) which was 3.17; (2) the average score of students’ activity had met sufficiently active criteria (2.5 – 3.4) which was 2.87; (3) students’ responds is in positive category (3.50 – 4.0) which was 3.51; (4) the everage of students’ learning result before the treatment was in very low category (0 – 54) which was 31.37 from the ideal score 100. The everage of students’ learning result after the treatment was in high category (80-89) which was 81.68 from the ideal score of 100. The everage of students’ improvement score (gain value) was in high category (x ≥ 0.7) which was 0,73. Based on inferential statistic analysis on students’ learning result after the treatment, it was obtained P-value < α (0.01 < 0.05) so H0 was rejected and H1 was accepted where the everage of students’ learning result was higher than 74.9 (KKM), and the everage of students’ learning improvement score (gain value) obtained P-value < α (0.01 < 0.05), so H0 was rejected and H1 was accepted where the everage of students improvement score (gain value) was higher than 0.29. Based on the results of the analysis of the level of holistic learning effectiveness concluded that the implementation of Experiences, Language, Picture, Symbol, and Apllication (ELPSA) on Cooperative Setting of Students Teams Achievement Division (STAD) Type is quite effective to be implemented in Mathematics subjects on class X SMP Negeri 29 Bulukumba.

The samples in this study were 2 classes, namely class VIII-1 which was used as an experimental class and class VIII-2 was used as a control class. The instrument used was a test in the form of a description of the material Relations and Functions. From testing the hypothesis obtained tcount (2.135) > ttable (1.6715) means that Ho is rejected and Ha is accepted. This shows the influence of think pair share type of cooperative learning on students' mathematical representation ability.
本研究旨在确定思维对共享型合作学习对学生数学表征能力的影响。本研究属于准实验研究。本研究中的人群都是SMP Negeri 1 Pangkalan Susu的八年级学生。本研究中的样本分为两类，即用作实验类的VIII-1类和用作对照类的VIII-2类。所使用的仪器是以材料关系和功能描述的形式进行的测试。通过测试所获得的假设，tcount（2.135）>ttable（1.6715）意味着Ho被拒绝，Ha被接受。这说明思维对共享型合作学习对学生数学表征能力的影响。

This research is a classroom action research, which aims to look at students' mathematical problem-solving abilities and student mathematics learning outcomes by applying the Contextual Teaching and Learning model in class XI IPA-1 SMA Negeri 21 Medan. The research subjects were 35 students. At the beginning of the study, observations were made to find out the weaknesses of students and the problems faced when teaching and learning activities took place. In addition to the data of mathematical problem-solving abilities that were analyzed, student learning activities were also analyzed. Based on the research results obtained observations in the first cycle; writing/reading (35.67%), working on student worksheets (23.33%), asking fellow friends (22%), asking teachers (12.33%), and activities not relevant to teaching and learning activities (6.67%). In the second cycle obtained writing/reading (28.3%), working on student worksheets (28%), asking fellow friends (24%), asking teachers (18.7%), and activities not relevant to teaching and learning activities (1%). The results for classical completeness obtained in the first cycle of 62.9%, but in the second cycle of 85.7%.
