EFEKTIVITAS MODEL PEMBELAJARAN KOOPERATIF TIPE NUMBERED HEADS TOGETHER DITINJAU DARI AKTIVITAS DAN HASIL BELAJAR MATEMATIKA

Abstract

The aim of this research is to find out the effectiveness of cooperative learning model
Numbered Heads Together (NHT) type observed by activity and math learning result.
This research is experimental research using Posttest-Only Control Design. The
populations was all of the students in first grade of the SMA Tri Sukses Natar. The
samples of the research were taken by using the cluster random technique. Data
obtained based on the observation of the learning process and student achievement test.
Each of these data are used to obatain students’ learning activities and results of
students’ mathematics learning. The data analysis technique is done by using
proportion test. Based on the results of data analysis showed that the percentage of
students activity more than 70% and the perecentage of students’ mathematics learning
outcomes gained more than 65%. Therefore, the NHT learning model is said to be
effectively applied in the first grade of the SMA Tri Sukses Natar.
