Abstract

Abstrak Pendidikan karakter melalui sekolah, tidak semata-mata pemberian pengetahuan, tetapi  penanaman moral, nilai-nilai etika, estetika, budi pekerti yang luhur. Salah satu budaya yang berkembang di masyarakat dan sangat dekat dengan peserta didik adalah permainan (rakyat).  Biasanya permainan rakyat menggunakan alat-alat yang masih sederhana yang mudah diperoleh dan ada di sekitar masyarakat setempat. Hal ini sangat sesuai dengan pendidikan matematika realistik Indonesia yang menggagaskan bahwa pembelajaran matematika harus merupakan ‘realitas’ yang dekat dengan peserta didik. Penelitian ini bertujuan untuk melakukan analisis pemikiran matematika dan kandungan nilai karakter pada permainan congkak yang dapat digunakan dalam pembelajaran matematika. Penelitian inidimulai dengan mengamati permainan congkak secara teliti yang dimainkan oleh peserta didik sekolah SD 018 Teluk Kenidai Kabupaten Kampar. Hasil pengamatan dijadikan dasar untuk melakukan analisis pemikiran matematika dan kandungan nilai karakter dalam permainan congkak. Hasil analisis menunjukan permainan congkak dapat digunakan untuk pengembangan karakter dalam pembelajaran matematika realistik untuk topik aritmatika di kelas 2,3 dan 4 sekolah dasar. Kata Kunci: permainan congkak, pendidikan karakter bangsa, pembelajaran matematika realistic Abstract Character education through school, not merely the provision of knowledge, but the cultivation of moral, ethical values​​, aesthetic, noble manners. One culture that developed in the community and very close to the students is the game (the people). Usually folk games using the tools that are simple, easy to obtain and there around the local community. This is in accordance with Indonesia realistic mathematics education which put forward the learning of mathematics that should be a ´reality´ which is close to the learner. This study aims to analyze the mathematical thinking and gynecology conceited character values ​​in a game that can be used in teaching mathematics. Research inidimulai by observing carefully cavalier game played by 018 elementary school students Kenidai Bay Kampar regency.

Abstract: This research is based on the lower result of students’ mathematic learning at class VIIIE of SMPN 18 Pekanbaru, which shows that only about 15,78% of students achieving KKM standard for algebra. This research aims to improve the learning process and students’ mathematic learning outcomes by implementing cooperative learning model TSTS type. This is a classroom action research with two cycles. The subjects of this research were class VIIIE of SMPN 18 Pekanbaru on odd semester academic year 2017/2018 which consits of 17 girls and 21 boys. The instrument of the data collector on this research are observation sheets and the test results of mathematic learning. The observation sheets were analyzed qualitatively to see the learning activities which had not maximize, in order to structured the improvement in second cycle, and for the test results were analyzed quantitatively. From the qualitative analization of this research, has known that there is an improvement of the mathematic learning activities for each meetings, since the first day of first cycle to the last day of second cycle. The research also shows the result of students’ mathematic learning based on individual development scors from first quiz to second quiz, where the students who get 20 and 30 are more than the students who get 5 and 10. The analysis of KKM standard achievement also shows an increasing of mathematic learning outcomes, which the percentage of basic score is 15,78%, the percentage of first quiz is 44,73%, and the percentage of second quiz is 57,89%. The conclusion of these result analysis is that the implementation of cooperative learning model Two Stay Two Stray (TSTS) type can improve the learning process and mathematic learning outcomes at class VIIIE of SMPN 18 Pekanbaru on odd semester academic year 2017/2018.Keywords: Mathematics Learning Outcomes, Cooperative Learning, Two stay Two stray, Classroom Action Research

Abstract

Abstrak The weakness of mathematics ability of students can be observed from material mastery of students. The student’s error on solving the problem is one of the clues to find out the material mastery of students. Therefore, that errors need to be identified to find the influence factors to get the solution. This study was implemented on Junior High School in Tampan Sub district which involve 3 schools, such as SMP 8, SMP 20, SMP 21 and the students of class IX. The purpose of this study were (1) Observing the kind of errors which were done by students on solving similarity problem (2) Observing the factors which caused the student’s error on solving similarity problem. Based on the data analysis, interview and investigation, it can be concluded that students had concept error, procedure error and carelessness error. The factors which caused the student’s error were lacking of effort on solving problems, lacking of mastery on the material, less of carefulness on solving problems, lacking of mastery on the prerequisite material and the students did not understand the steps on solving problem. Keywords: Analysis of Error, Similarity, Concept Error, Procedure Error.
