THE EFFECT OF TEAM ASSISTED INDIVIDUALIZATION METHOD ON STUDENTS’ ACHIEVEMENT IN WRITING PROCEDURE TEXT

This study intended to find out the effect of Team Assisted Individualization method on students’ achievement in writing procedure text. It was conducted by using experimental research design. The population of this study was the first (X) grade students of SMA Ar-Rahman Medan. It consisted of 90 students with three parallel classes. Sixty students were chosen as the sample by using random sampling technique. There were two randomized groups, namely experimental group and control group. Class X-2 with 30 students became the experimental group while class X-1 with 30 students became the control group. The experimental group was taught by using Team Assisted Individualization method and the control group was taught by Two Stay Two Stray method. The instrument which was used for collecting the data was writing test. The data was analyzed by using t-test formula. The result showed that the mean score in experimental group is higher than control group, namely 81.46 for experimental group and 71.5 for control group. The value of tobserved (3.37) is higher than the value of ttable (2.004) (α = 0.05) with the degree of freedom (df) = 58. So, alternative hypothesis (Ha) was accepted and the Team Assisted Individualization significantly affected students’ achievement in writing procedure text.
