Abstract

Penelitian ini bertujuan untuk mengetahui kemampuan representasi matematis peserta didik yang memperoleh pembelajaran melalui model Problem Based Learning (PBL) dan model pembelajaran langsung. Kemampuan representasi matematis tersebut dianalisis dengan memperhatikan kemampuan penalaran matematis. Penelitian ini merupakan penelitian kuantitatif dengan populasi semua peserta didik Program Studi Pendidikan Matematika FMIPA Universitas Indraprasta PGRI yang sedang menempuh mata kuliah Analisa Real pada semester genap tahun akademik 2018/2019. Sampel terdiri dari dua kelompok yang masing-masing terdiri dari 33 mahasiswa. Data pada penelitian ini dikumpulkan melalui metode tes. Analisis data dilakukan dengan analisis kovariansi. Hasil penelitian ini menunjukkan bahwa terdapat perbedaan yang signifikan kemampuan representasi matematis antara peserta didik calon pendidik yang memperoleh pembelajaran melalui model PBL dan model pembelajaran langsung. Perbedaan kemampuan representasi matematis tersebut diperoleh dengan memperhatikan kemampuan penalaran matematis.

Abstract

Students from various educational levels experience difficulties in learning mathematics. The first problem in learning mathematics is the difficulty in understanding mathematical concepts. Some students forget the main material that was discussed at the previous level. The second problem is students' perception of mathematics. Students view mathematics as a difficult and boring subject, which makes them lazy to study mathematics. The third problem is the lack of motivation due to online games. Students tend to be happy when playing, but are not enthusiastic when taking math lessons. Students studying mathematics must understand mathematical concepts first so they can solve problems and able to apply this learning in the real world.  The purpose of this study is to determine how much influence learning independence has on the mathematical concept understanding ability of grade 10 students of SMAN 80 North Jakarta. The method used in this study is the simple regression analysis method. The sample in this study was 55 students taken using a purposive sampling technique. Before conducting the hypothesis test, the data is tested for normality and linearity.  Data analysis using simple regression. The results of the study show that there is a positive influence between learning independence and the ability to understand mathematical concepts of 72,18% with the regression equation ????̅= 83,42 + 0,02x and thitung > ttabel = (3,246 > 2,006.
