PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE NUMBERED HEADS TOGETHER TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA KELAS VIII SMPN 2 GUNUNG TALANG

Abstract

The aimed of this study was to determine the students mathematics problem solving skill with the application of cooperative learning model type Numbered Heads Together better than without conventional learning in class VIII in SMPN 2 Gunung Talang. The type of the research was a quasi-experiment with Randomized Control Group Design Only as design research. The populations in this study were the students of class VIII SMPN 2 Gunung Talang, with Cluster Random Sampling as sampling technique. Tthe sample of this research were VIII_D as an experimental class with the number of 32 people and class VIII_F as the control class with the number 33 people. After the data analysis obtained both sample classes were normally distributed and homogeneous at the level of ? = 0.05. The data analysis technique used was one party test. Based on the z_calculate = 1,37 and z_table = 0,91. At the 95% confidence level, it means z_calculate>z_table then H₀ was rejected and H₁was accepted, there for the students mathematics problem solving skill with the application of cooperative learning model type Numbered Heads Together better than without conventional learning in class VIII in SMPN 2 Gunung Talang.
