Application of Cooperative Learning Model of Two Stay-Two Stray (TSTS) Type on the Reaction Rate Material on the Students’ Learning Outcomes in Class XI SMA Negeri 1 Banawa Tengah

This study aims to analyze the influence of students’ learning outcomes on reaction rate by applying the cooperative learning model type TSTS (two stay-two stray) in class XI SMA Negeri 1 Banawa Tengah. The type of research was quasi-experimental (quasi-experimental research) with a nonrandomized pretest-posttest control group design. This study was conducted on two classes, namely class XI IPA 1 as an experimental (n= 32) and class XI IPA 2 as the control class (n= 32). Analysis data used the two-party t-test statistical with the prerequisite test, namely normality and homogeneity test. The results showed that the learning outcomes of students in the experimental class X̅1was 76.93 with a standard deviation = 8.62 while in the control class X̅2 was 72.06 with a standard deviation= 8.53. The results of hypothesis testing obtained – ttable≤ tcount + ttable which was -1.67 <3.25> +1.67 with a significant level (α= 0.05) and degrees of freedom = 62. This showed that H0 was rejected and H1was accepted it can be concluded that there is an effect of the application of the two stay-two stray (TSTS) type cooperative learning model on the reaction rate to the students’ learning outcomes of class XI SMA Negeri 1 Banawa Tengah
