The effectiveness of using the student teams achievement divisions (Stad) technique towards students� understanding of the simple past tense (a quasi-experimental study at the eighth grade students of SMP Trimulia, Jakarta Selatan)

The objective of the study was to know empirical evidence whether using the Student Teams Achievement Divisions (STAD) technique is effective of not for students in understanding the simple past tense. There are 62 grade eighth students of SMP Trimulia who have been chosen from two classes VIII.B as an experimental class and VIII.A as a controlled class. It started with a pre-test for both classes, treatment manipulation in experiment class and last conducted the post-test. The data was collected by the test instrument and analyzed by using the t-test formula. The result of statistical calculation showed, the value of t0 is 4.30. With the degree of freedom (df) is 62 is gained the value 1.99 and 2.65 on the degree of significance 5% and1% of the table. Comparing the gained value of t0 with ttable, it can be seen that there is an obvious differences among the score of experiment class and control class. The t0 value is higher than the ttable, namely 1.99 2.65, hence the alternative hypothesis (Ha) is accepted and the null hypothesis (Ho) is rejected. Consequently, it has been proven that the using of Student Teams Achievement Divisions (STAD) technique is effective for students of SMP Trimulia in understanding the simple past tens
