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. Observations used as the basis for mathematical thinking, and content analysis of the value of the character in the game cocky. The results of the analysis showed cavalier game can be used for the development of realistic characters in learning mathematics to arithmetic topics in class 2,3 and 4 elementary schools. Keywords: game cocky, national character education, learning mathematics realistic

Abstract

Absract : This classroom action research is aimed to improve learning process and mathematics learning outcomes by implementing Problem Solving Strategy in Problem Based Learning. The research subjects are 40 heterogeneous academic ability level students of the VII8 class of Junior High School 8 Pekanbaru in academic year of 2015/2016. This research implemented in two cycles in which each cycle consisted of four phases, i.e: namely planning, implementing, observing and reflecting. By the end of each cycle, formative test was given. The data was collected by doing observation of teachers and students activities and formative test. The research shows learning process improvement after the implementation Problem Solving Strategy in Problem Based Learning.  Most of student participated actively and responsible in the learning process like discussing, presenting, responding and drawing the lesson conclusion. The member of students passing the Minimum Completeness Criteria (KKM) on base score, formative tes I (first cycle), formative test II (second cycle) were respectively 37,5%, 67,5% and 85%. The persentage of KKM achievement also indicates the increase after the implementation , this it can be said that the students learning outcomes also increase. The results of this research indicate that the implementation of Problem Solving Strategy in Problem Based Learning can improve the learning process and improve mathematics learning outcomes of VII8 class students at state junior high school 8 Pekanbaru in the academic year 2015/2016.

Abstract: This research is a developmental research which aims to produce computer-based learning media interactive tutorial model on the subject circle for class VIII SMP/ MTs that is valid and practical. This developmental research used development model based on the teory of Borg and Gall. The stages are: (1) potential and problem; (2) literature collection; (3) product design; (4) product validation; (5) product revision; (6) product tested; (7) product revision; (8) product tested in large group; (9) product revision. In the first stages, the researcher analyzed potentials and problems. After that, the researcher collected the reference materials, then designed the product and put it into a computer. The learning media that had been developed was be evaluated by three validators based on the aspects of learning, display, program and curriculum, and revised according to the advice of the validator. Next, the learning media that had been revised was be tested in two stages: product testing in small groups with the subject of five students of class VIII SMP Juara Pekanbaru and product testing in large groups with the subject of 25 students class VIII SMP Juara Pekanbaru. Based on the results of data analysis and discussion, it can be concluded that the computer-based learning media interactive tutorial model for the subject circle class VIII SMP / MTs assessed valid by experts with an average value of 3.59 and received a very good response from students of class VIIIKeywords: Computer-based Learning Media, Research and Development, Circle

Abstract : The aim of this research is to develop interactive computer-based tutorial for mathematics class VII topics of lines and angles. This research use development model by Borg and Gall modified by Sugiyono (2011). Development is done through the following steps: (1) potentials and problems; (2) data collection; (3) media design; (4) validation; (5) revision; (6) small group test; (7) revision; (8) large group test; and (9) revision. At the stage of potentials and problems, researchers created a needs analysis of the results of interviews with teachers of Mathematics. Based on the needs analysis, learning media developed for six class meetings. Learning media is validated by three experts and further revised based on the input from validators. The revised learning media was tested on a small group consist of five students of class VII. The learning media was revised and test in large group involved 21 students of class VII SMP N 1 Rengat. From the large group test results, the learning device improved. The result of data analysis and discussion shows that interactive computer-based tutorial for mathematics class VII topics of lines and angles are valid with an average value of 3.57 and is practical to use by students of class VII.

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.
