Abstract

One of mathematics learning purposes for students is having the capability or skill to solve a mathematics’ problem, as a means for students to sharpen accuracy, logical, critical, analitycal, and creative reasoning so that problem was not a problem anymore for students. For optimal learning process, it is necessary supported by relevant learning device. This is the basis for research in mathematics learning device development like lesson plan and students worksheet based on Guided Discovery Learning model where learners are also learning and thinking to solve their problems independently through the materials facilitated by teachers and teacher’s guidance. This was a development research which applied Plomp model. Based on the result of research, it could be concluded that guided discovery learning was valid.

Abstract

Problem solving ability is a very important to attainment of objectives mathematics learning. In fact, the problem solving ability of student is still low. One of the efforts to improve the problem solving ability is handout development on contextual based-approach. The purpose of this development research is to know the characteristics handout on contextual based-approach which are valid, practical, and effective. This development research uses a Plomp model consisting of three phases namely : preliminary, prototyping, and assessment. The instruments were used in this study are validation sheets for RPP and handout, questionnaire for teacher and students, sheets of observation, and test. Handout on contextual based-approach has been valid with validity was 3.58 and it was practical with practicality level of the according to the teachers’ response gave 87,86% and students' response was 82.73%. They also efective to improve the problem solving ability of student.

Abstract

The ability to think creatively is an ability that is expected to be mastered by students but is still low. Students lack the ability to solve a problem in a various ways.The purpose of this study is to produce a learning tool based on M-APOS theory to improve students' creative thinking abilities.The research method used in this research is research and development which consists of three stages, namely the initial investigation stage, the development stage and the assessment stage.In this section what is done is the preliminary research stage. The instruments used were interview and questionnaire guidelines.The results of the study are: 1) inadequate school facilities and infrastructure, 2) student learning outcomes are still low because students are accustomed to accept what is taught and do not repeat the lessons at home, 3) worksheets that are used by students is not attractive, 4) in the learning process students prefer group learning, 5) students want the questions contained in LKPD to be daily life problems, 6) the learning environment of students who are in the hills and close to the highway, 7) learning styles favored by students are in the form of solving problems in the form of images related to daily life problems, 8) the appearance of worksheets that are liked by students is LKPD which has  pictures and attractive color.

Abstract

This research aimed to develop local instruction theory that is valid, practical, and effective to help elementary school students developing their mathematical problem-solving skills. Therefore a sequential activityis design on dailybasis to encourage students to develop their ability to solve mathematical problems, especially on the topic division. To achieve the goal, realistic mathematics approach was implemented to grade three elementary students in the learning process. The designed activities were validated by experts on the aspects of mathematical contents, language, didactical process based on realistic mathematical approach. Data were analyzed with descriptive statistics and parametric statistics. The validation results show that the local instruction theory was valid, and the implementation shows that the local instruction theory is practical and effective in improving students' mathematical problem-solving skills.

Abstract

Penelitian ini bertujuan untuk mengetahui perberdaan kemampuan pemecahan masalah matematis peserta didik yang memperoleh pembelajaran model Problem Based Learning (PBL) dengan siswa yang menggunakan model pembelajaran konvensional yang ditinjau dari gender (laki-laki dan perempuan) dan level sekolah (tinggi, sedang, rendah) di MTsN Kabupaten Tanah Datar. Jenis peneltian adalah eksperimen dan desain penelitian yang digunakan Randomized Pretest-Posttest Control Group Design dengan variabel bebas model PBL dan konvensional, variabel terikat adalah kemampuan pemecahan masalah matematis dan variabel moderator adalah gender dan level sekolah dengan  jumlah sampel sebanyak 146 siswa. Teknik pengolahan data dengan menggunakan uji-t, uji-U dan uji ANOVA dua arah. Hasil penelitian ini menunjukkan bahwa: (1) Kemampuan pemecahan masalah matematis siswa yang belajar dengan model PBL lebih tinggi dibandingkan dengan yang belajar dengan model konvensional di sekolah level tinggi, sedang dan rendah. (2) Kemampuan pemecahan masalah matematis siswa laki-laki dan perempuan yang belajar dengan  model PBL lebih tinggi dibandingkan dengan yang belajar dengan model konvensional.(3) Kemampuan pemecahan masalah matematis siswa perempuan lebih tinggi dibandingkan laki-laki (4)  Tidak  terdapat  interaksi antara model pembelajaran dan gender  dalam mempengaruhi kemampuan pemecahan masalah matematis siswa. (5) Tidak  terdapat interaksi antara  model pembelajaran  dan level sekolah dalam mempengaruhi kemampuan pemecahan masalah matematis siswa.Kata kunci: Gender, kemampuan pemecahan masalah matematis, level sekolah, Problem Based Learning AbstractThis study aims to determine the difference in mathematical problem-solving abilities of students who obtain Problem Based Learning (PBL) learning models with students who use conventional learning models in terms of gender (male and female) and school level (high, medium, low) in MTsN Tanah Datar District. This type of research is the experimental and research design used by the Randomized Pretest-Posttest Control Group Design with independent variables PBL and conventional models, the dependent variable is the ability to solve mathematical problems and the moderator variable is gender and school level with a total sample of 146 students. Data processing techniques using t-test, U-test and two-way ANOVA test. The results of this study indicate that: (1) The mathematical problem-solving ability of students who learn with PBL models is higher than those who learn with conventional models in high, medium and low level schools. (2) Mathematical problem solving ability of male and female students learning with PBL models is higher than those learning with conventional models. (3) Mathematical problem solving abilities of female students are higher than male students (4) There is no interaction between learning models and gender in influencing students' mathematical problem solving abilities. (5) There is no interaction between learning models and school level in influencing students' mathematical problem solving abilities.Keywords: Gender, mathematical problem solving ability, school level, Problem Based Learning.
