Abstract

This article is a study that aims to describe the ability to solve contextual problems of class IXhigh school students on the basis of material and series. Problem solving is a very important part of learning mathematics because in the process of learning and solving math problems, it is possible for students to gain experience using the knowledge they already have. One of the problem solving methods used is according to Polya. There are four initial steps to solving a problem according to Polia, namely understanding the problem, making a problem solving plan, carrying out a settlement plan and re-examining the results of the settlement. Based on this, a study was conducted which aimed to determine the development of students' problemsolving abilities and to find out whether there were significant differences in student learning outcomes between before and after being given the problem-solving method according to Polya. The results obtained in this study were that students were able to understand the problem from the questions and get the answers correctly but in compiling and implementing student plans it was not appropriate when using the stages from Polya.

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya kemampuan pemecahan masalah matematis siswa kelas VII MTs Nurul Falah. Penelitian ini bertujuan untuk mengetahui efektivitas dengan menggunakan model pembelajaran Somatic Auditory Visualization Intellectually (SAVI) berbantuan aplikasi GeoGebra dengan pembelajaran konvensional terhadap kemampuan pemecahan masalah matematis siswa kelas VII MTs Nurul Falah. Jenis penelitian ini ialah Quasi eksperimen, dengan design The Randomized Posttest Only Control Design. Populasi pada penelitian ini adalah kelas VII. Sampel dipilih menggunakan teknik  simple random sampling berdasarkan uji normalitas, uji homogenitas, uji kesamaan rata-rata. Dari hasil tes awal dengan teknik Simple Random Sampling yang kemudian diperoleh kelas VII A sebagai kelas eksperimen dan kelas VII C sebagai kelas kontrol. Teknik pengumpulan data pada penelitian ini yaitu tes kemampuan pemecahan masalah matematis siswa. Teknik analisis dalam penelitian ini menggunakan Uji-t diperoleh thitung > ttabel (6,668 > 1,998) dan Sig. < 0,05, yaitu 0,00 < 0,05 dengan (df) n-2 maka keputusan yang diambil adalah H1 diterima H0 ditolak. Sehingga dapat disimpulkan bahwa “ Model pembelajaran Somatic Auditory Visualization Intellectually (SAVI) berbantuan aplikasi GeoGebra efektif terhadap kemampuan pemecahan masalah matematis siswa kelas VII MTs Nurul Falah”.
