THE EFFECTIVENESS OF STUDENT TEAM ACHIEVEMENT DIVISION (STAD) ON ENGLISH LEARNING OUTCOMES AND STUDENT LEARNING MOTIVATION

This study aims to determine the effect of the Student Team Achievement Division (STAD) learning method on learning outcomes and student learning motivation that has been analyzed by eighth semester students of the English Education Study Program at Nahdlatul Ulama Sunan Giri Bojonegoro in 2023/2024. This study used quantitative method to describe in detail the effect of STAD method. In this study, the researcher used two classes, namely the experimental class and the control class with a total of 66 students of class X in the 2023/2024 academic year. The results of the study indicated that the alternative hypothesis (Ha) was accepted, meaning that there was a significant difference between the post-test scores of students from the experimental group and the control group. Students' learning outcomes changed before and after treatment. The average post-test score of the experimental group was 76.69 and the average post-test score of the comparison group was 57.30. The independent post-test value of significant (2-tailed) is lower than 0.05 or 0.000 < 0.05. From the effect size statistics with eta squared, the researcher found the value of eta squared was (0.63). The value obtained from eta squared indicates a moderate effect size. Students' learning motivation experienced a large increase, the average post-test score of the experimental group was 37.79 and the average post-test score of the comparison group was 29.41. The independent post-test value of significant (2-tailed) is lower than 0.05 or 0.000 < 0.05. From the effect size statistics with eta squared, the researcher found the value of eta squared was (1.78). The value obtained from eta squared indicates a large effect size. Based on the findings and discussion in this study, the researcher concluded that the STAD method has a significant effect on improving learning outcomes and learning motivation of MA Al-Falah Bangilan Tuban students.
