The method used is a quantitative experiment method using True Experimental Design specifically on Posttest-Only Control Design and the data is tested by t-test. The result of data analysis shows the differences on average (Mean) the control group (non-cooperative learning) is 63, 52; analyzed case as amount is 25; Standard Deviation is 19.194 ,and average (Mean) the experiment group (cooperative learning) is 79,20; analyzed case as amount is 25; Standard Deviation is 12,111. The T- Test shows that the Sig (2-tailed) is 0,001 <0, 05 means Ho is rejected and Ha is accepted. In conclusion, there is a significant difference in English grammar achievement scores of the students taught through cooperative language learning.
