KORELASI ANTARA SELF-EFFICACY DENGAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIK PESERTA DIDIK MENGGUNAKAN MODEL PEMBELAJARAN KOOPERATIF TIPE NUMBERED HEADS TOGETHER (NHT)

Abstract

This research aimed to figure out the correlation between self-efficacy with mathematical problem solving abilities using Numbered Heads Together model. The method used in this research was an experimental method. The populations were all of the students at 7th grade of SMP Negeri 2 Kota Tasikmalaya and the sample used was VII I class using random sampling technique, then they were given mathematic learning with Numbered Heads Together. Data were collected through test mathematical problem solving abilities, and questionnaire self-efficacy. The technique was using simple linear regression test. Based on the data analysis, it could be concluded that there was correlation between self-efficacy with mathematical problem solving ability through Numbered Heads Together model, and were classified as medium. The second conclusion was student self-efficacy whose learning by using of Numbered Heads Together model were classified as medium  .
