Pengaruh penggunaan model pembelajaran kooperatif tipe Numbered Heads Together (NHT) terhadap hasil belajar matematika siswa SMA

Abstract

This study aims to determine the effect of using the cooperative learning model, Numbered Heads Together (NHT), on high school students' mathematics learning outcomes. The research employed a quantitative approach with an experimental method and a quasi-experimental nonequivalent control group design. The sample consisted of two 10th-grade classes in a senior high school: an experimental group taught using the NHT model and a control group taught using conventional methods. Data on students' learning outcomes were collected through multiple-choice written tests. Data analysis included normality tests, homogeneity tests, and t-tests to test the research hypothesis.The results showed that the average learning outcomes of the experimental group were 85.20, higher than the control group’s average of 78.40. The t-test indicated a significance value of p < 0.05, confirming a significant difference between the two groups. These findings demonstrate that the cooperative learning model, NHT, has a significant positive effect on high school students' mathematics learning outcomes. The implementation of this model enhances student engagement, conceptual understanding, and overall learning achievement.
