Abstract

This research aimed to find out the effectiveness of Realistic Mathematic Education approach in terms of students understanding of mathematical concepts. The population of this research was students of grade VII in SMP Negeri 1 Adiluwih in academic year of 2016/2017 that were distributed into 6 classes. The samples of this research were students of VII A and VII B class which were chosen by purposive and random sampling technique. The design was posttest only control group design. Analysis data of the research used t-test. Research data were obtained through test of understanding of mathematical concepts. Based on the result of the research, it was concluded that Realistic Mathematic Education approach was not effective in terms of students' understanding of mathematical concepts. But, the students understanding of mathematical concepts which was taught by Realistic Mathematic Education approach was better than students understanding of mathematical concepts which was not taught by Realistic Mathematic Education approach.Penelitian ini bertujuan untuk mengetahui efektivitas pendekatan Realistic Mathematic Education ditinjau dari pemahaman konsep matematis siswa. Populasi penelitian ini adalah seluruh siswa kelas VII SMP Negeri 1 Adiluwih tahun pelajaran 2016/2017 yang terdistribusi dalam 6 kelas. Sampel penelitian ini adalah siswa pada kelas VII A dan VII B yang diambil dengan teknik purposive dan teknik random sampling. Desain yang digunakan adalah posttest only control group design. Analisis data penelitian ini menggunakan t-test. Data penelitian diperoleh melalui tes pemahaman konsep matematis. Berdasarkan hasil penelitian, disimpulkan bahwa pendekatan Realistic Mathematic Education tidak efektif ditinjau dari pemahaman konsep matematis siswa.

The research population were all students grades VIII of SMP Negeri 22 Bandarlampung in academic year of 2017/2018 that were distributed into eleven classes. The research sample were grades VIII F and VIII H that were chosen by purposive sampling technique. The research design was the pretest-postest control group design. The data analysis used is t-test and t’-test. The research result shows that gain of student’s mathematical reflective thinking ability in problem based learning class is higher than in conventional learning class, and self confidence isn’t higher than. Based on results and discussion, it can be concluded that problem based learning model has influence towards student's mathematical reflective thinking ability, but hasn't influence towards student's self confidence.Penelitian eksperimen semu ini bertujuan untuk mengetahui pengaruh problem based learning terhadap kemampuan berpikir reflektif matematis dan self confidence siswa.

Abstract

This study aims to determine the effectiveness of problem-based learning model in terms of the ability to think critically and mathematical representation of grade VIII students at a State Junior High School in Bandarlampung City. The population in this study are all students of class VIII distributed in eleven classes. The samples of this study are the students of two classes VIII whose class is selected by purposive random sampling technique. The research design is Pre-test Post-test Control Group Design. Mann-Whitney U non parametric test results on critical thinking and mathematical representation, indicating that H0 is rejected, thus drawn the conclusion that mathematical critical thinking and mathematical representation of students who follow PBL is higher than mathematical critical thinking and mathematical representation of students following learning conventional. The proportion test shows that the percentage of students who have critical thinking skills and mathematical representations are categorized well in the class using the PBL more than 60% of the number of students. The result of the research shows that learning with effective PBL model is viewed from critical thinking ability and student's mathematical representation Keywords:  Problem Based Learning, Critical thinking, Mathematical Representation
