This research is motivated by the results of previous research which shows that students' mathematical reasoning ability is not as expected. One of the lessons to improve the ability of mathematical reasoning is inductive learning. The purpose of this research is to know the improvement of students' mathematical reasoning ability as a result of inductive learning. This study is a quasi-experiment that implements two lessons namely inductive learning and conventional learning. Population in this research is a student of the junior high school in Regency of West Bandung. Sampling was done by purposive sampling and obtained two classes as research sample. The research instrument used is the test of mathematical reasoning ability. Based on the result of the analysis, it can be concluded that the improvement of mathematical reasoning ability of students who get inductive learning is better than students who get conventional learning.

Penelitian ini bertujuan untuk mendeskripsikan: 1) keefektifan pendekatan problem solving terhadap kemampuan pemahaman dan penalaran matematis; 2) keefektifan pendekatan problem posing terhadap kemampuan pemahaman dan penalaran matematis; 3) perbandingan keefektifan antara pendekatan pembelajaran problem solving dan problem posing terhadap kemampuan pemahaman dan penalaran matematis siswa SMP pada pembelajaran bangun ruang sisi datar. Penelitian ini merupakan penelitian eksperimen semu (quasi experiment). Data dianalisis menggunakan one sample t test, uji MANOVA rumus T2 Hotteling, dan uji t kriteria Bonferroni. Hasil penelitian menunjukkan bahwa: 1) pendekatan problem solving  efektif terhadap kemampuan pemahaman dan penalaran matematis; 2) pendekatan problem posing efektif terhadap kemampuan pemahaman dan penalaran matematis; 3) pendekatan problem solving lebih efektif dibandingkan problem solving terhadap kemampuan pemahaman matematis tetapi pendekatan problem solving tidak lebih efektif dibandingkatn problem posingterhadap kemampuan penalaran matematis siswa SMP pada pembelajaran bangun ruang sisi datar.Kata kunci: pendekatan problem solving, pendekatan problem posing, kemampuan pemahaman matematis, dan kemampuan penalaran matematis. The effectiveness comparison of problem solving and problem posing approaches in mathematics learning towards junior high school students AbstractThe aim of this study is to describe: 1) the effectiveness of problem solving approach on mathematical understanding and reasoning ability; 2) the effectiveness of problem posing approach on mathematical understanding and reasoning ability; 3) the comparison effectiveness of polyhedral learning using problem solving approach and problem posing approach on mathematical understanding and reasoning ability of State Junior High School. This study was a quasi experiment. The data were analyzed using one-sample t test, MANOVA test with T2 Hotteling's formula, and t-test with Bonferroni criterion. The results of the study show that: 1) the problem solving approach has an effect on mathematical understanding and reasoning ability; 2) the problem posing approach has an effect on mathematical understanding and reasoning ability; and 3) the problem solving approach is more effective than the problem posing approach on mathematical understanding ability, but the problem solving approach is not more effective in polyhedral learning than the problem posing approach on mathematical reasoning ability of State Junior High.Keywords: problem solving approach, problem posing approach, mathematical understanding ability, and mathematical reasoning ability

Reasoning Abilities

The abilities that must be mastered by high school students according to the demands of the 2013 curriculum include reasoning. Students who have good reasoning abilities make it easier to understand mathematics. But in reality there are still many students who have low mathematical reasoning ability, seen when they have difficulty solving math problems. This research objective is to prove the habit of solving open-ended problems that can improve the mathematical reasoning ability of junior high school students based on the level of initial mathematical ability: high, medium, and low. The study used an experimental method with a "One-Group pre-test post-test design". Randomly, selected 77 grade VII students of SMP Negeri in Bekasi as a sample. The prerequisite test shows that each level of data comes from groups that are normally distributed and homogeneous. The results showed normal gain, both overall and level showed improvement. Based on the t test obtained p value of 0.000 < 0.005, meaning this study can prove student habits in solving open-ended problems when learning mathematics on triangles and quadrilateral, can improve students' mathematical reasoning abilities.

AbstractThis study aims or determining whether the achievement and improvement of mathematical reasoning of junior high school students who learn using open-ended approach is better than using conventional learning. The research conducted was experimental research. The population in this study was all junior high school students in Kabupaten Bandung Barat. While the samples were taken two classes VIII from one grade, where class VIII B became experimental class and class VIII A became the control class . The instrument used in the research was in the form of five essay tests that measure students' mathematical reasoning. To know the improvement of student's mathematical reasoning before and after learning activity, normalized gain calculation was done, then data of pretest and postes result were processed by normality, homogeneity and difference average tests. Based on the analysis of the data resul processing in this study, it could be concluded that the achievement and improvement of mathematical reasoning among students who learn using open-ended approach was better than using conventional learning.Keywords: Open-Ended Approach, Mathematical Reasoning

This research is motivated by the results of previous research which shows that students' mathematical problem-solving ability is not as expected. One of the learning to improve the problem-solving ability of mathematics is problem-based learning. The purpose of this study is to determine the improvement of students' mathematical problem-solving skills as a result of problem-based learning. This study is a quasi-experiment that implements two lessons: problem-based learning and conventional learning. Population in this research is a student of the junior high school in Regency of West Bandung. Sampling was done by purposive sampling and obtained two classes as research sample. The research instrument used is the test of mathematical problem-solving ability. Based on the results of the analysis, it can be concluded that the improvement of the problem-solving ability of mathematical students who get problem-based learning is better than the students who get conventional learning.
