Abstract

Penelitian ini bertujuan untuk kemampuan pemecahan masalah matematis siswa setelah diberikan perlakuan model pembelajaran kooperatif investigasi. Designe penelitian yang digunakan dalam penelitian ini adalah penelitian kuasi eksperimen dan berbentuk ”Randomized Control Group Only Design”. Subjek dalam penelitian ini adalah siswa kelas X5 dan kelas X2 SMAN 2 Lubuk Sikaping. Pengumpulas data dilakukan dengan memberikan tes. Dari hasil penelitian dan pembahasan diperoleh rata-rata nilai kemampuan pemecahan masalah dikelas eksperimen 78 dan kelas kontrol 69,59.  Nilai Simpangan baku pada kelas eksperimen lebih kecil dibanding dengan kelas kontrol. Hal ini menunjukkan bahwa nilai pada kelas eksperimen lebih menyebar mendekati rata-rata dibanding dengan kelas kontrol. Melalui uji statistik beda rata-rata dapat disimpulkan bahwa kemampuan pemecahan masalah matematis siswa yang diajar dengan menggunakan model pembelajaran Investigasi lebih baik daripada hasil belajar siswa dengan pembelajaran konvensional di kelas X SMAN 2 Lubuk Sikaping tahun pelajaran 2014/2015.

Abstract

This study aims to determain the ability of SAVI approach effect  to ability of activity in matemathical learning in class X SMAN 1 Ampek Angkek. The study was a pre-experimental whit the one shot case study design. The subjects of this rearch were students in class X SMAN 1 Ampek Angkek. The research subjecthe results are given treatment that is making a learning Cycle whit  SAVI approach on the learning process. The data of this research obtained  in the from of value the abilty to make learning Cycle whit  SAVI approach, the value of ability to activity in matemathical learning in class X SMAN 1 Ampek Angkek. The research is a correlational research. The population of this study were all students of class X SMA N 1 Ampek Angkek. The data were analiyzed by regression analysis. The results show that there is an influence of activity-based learning students  = 47.19 + 1.284 X, and determination R2 = 41,7 %. This means, 41,7 % of the total variation in the ability of activity based learning students.
