Abstract

This study aims to determine the effect of the Number Heads Together (NHT) cooperative learning model on students’ critical thinking skills in Natural and Social Sciences (IPAS). The study employed a quantitative approach with a quasi-experimental nonequivalent control group design. The sample consisted of 54 third-grade students of SD Negeri Joglo Surakarta, divided into an experimental class and a control class with 27 students each. Data were collected through essay tests, observation, and documentation. The data were analyzed using normality, homogeneity, independent sample t-test, and N-Gain tests. The results showed that the data were normally distributed and homogeneous. The average posttest score of the experimental class was higher than that of the control class. The t-test result showed a significance value of 0.000 < 0.05, indicating a significant effect of the NHT learning model on students’ critical thinking skills. The N-Gain score of the experimental class was 0.75 (75.69%) in the high category, while the control class obtained 0.33 (33.03%) in the low category. Therefore, the Number Heads Together learning model is effective in improving students’ critical thinking skills in IPAS learning.
