This Classroom Action Research was aimed at looking at the possible improvement in the process and the results of teaching Grammar III at the English Education, Pendidikan Bahasa Inggris (PBI) Department of the Education and Teacher Training Faculty (FTK), Fakultas Tarbiyah dan Keguruan, Ar-Raniry National Islamic University (UIN) Banda Aceh. The Student-Teams Achievement Division (STAD) Cooperative Technique was used in this research. In this cooperative technique, the students were put into 3 groups of 4 members for each. The groups were heterogeneous in terms of their ability. This action research was carried out over two cycles, Cycle I and II. This cooperative technique did improve the teaching process and the results. The results from observations and reflections showed that the group members worked cooperatively. They shared and discussed the task assigned to them. More importantly, they helped one another and developed tolerance. All of them enjoyed learning using STAD. In this technique the learners really construct knowledge by using inquiry learning and cooperative activities. The average score of pre-test was 67 of cycle I, posttest average was 87 and that of cycle II posttest was 88. Since this technique was proven to be effective it is recommended that the STAD Cooperative Technique be used in teaching Grammar and/or other English courses or even for any other courses particularly those that contain difficult concepts.
