Abstract

Abstract: This research is about the application of cooperative learning model Two Stay Two Stray (TSTS) type that has conducted to know the increasing of student’s learning achievement on atom structure and chemical element periodic system topic in class X at SMA N 2 Tambang. This research was experiment by design pretest and posttest. The sample determined nonrandomly after doing normality and homogeneity test of 9 classes as population and then class X.4 as experiment group and X.5 as control group. The experiment group was applied by the application of cooperative learning model Stay Two Stray (TSTS) type. The data analysis technique used was t - test. Based on the tabulation of last data obtained t_count> t_table was 3,33 > 1.68 meant that the application of cooperative learning model Two Stay Two Stray (TSTS) type could increase the student’s learning achievement on atom structure and chemical element periodic system topic in class X at SMA N 2 Tambang.
