COMPARISON OF LEARNING OUTCOMES IN WRITING OBSERVATION REPORTS USING THE GROUP INVESTIGATION METHOD VERSUS THE STUDENT TEAMS ACHIEVEMENT DIVISION METHOD FOR GRADE X STUDENTS AT SMK BRAHMA HARDIKA INDONESIA

Abstract

his study aims to determine whether there is a comparison between the use of the Group Investigation method and the Student Teams Achievement Division method in writing observation reports for grade X students at SMK Brahma Hardika Indonesia. This research was conducted at SMK Brahma Hardika Indonesia in the second semester of the 2014-2015 academic year. The sample consisted of 60 students from grade X Computer Network Engineering and X Light Vehicle Engineering, all of whom were studied. The instrument was an essay test. The normality test of pretest and posttest results using the Liliefors test in the control class yielded Lcount = 0.1141 and Ltable = 0.161 at α = 0.05. In the experimental class, Lcount = 0.1352 and Ltable = 0.161 at α = 0.05 (Pretest). In the control class, Lcount = 0.0649 and Ltable = 0.161 at α = 0.05. In the experimental class, Lcount = 0.1012 and Ltable = 0.161 at α = 0.05 (Posttest). For both samples, Lcount < Ltable, so it can be concluded that both samples are normally distributed. The homogeneity test using the Fisher test yielded Fcount = 1.352 at α =0.05 with Ftable = 1.858 (Pretest) and Fcount = 1.109 at α =0.05 with Ftable = 1.858 (Posttest). Since Fcount < Ftable, it can be concluded that the samples have homogeneous conditions. The hypothesis test using the t-test yielded tcount = 2.371 and ttable = 2.021 at α =0.05 (Pretest) and tcount = 3.409 and ttable = 2.021 at α =0.05 (Posttest). Since tcount > ttable, H0 is rejected and H1 is accepted, meaning it is significant. From the data obtained, it can be concluded that there is a comparison between the use of the Group Investigation method and the Student Teams Achievement Division method in writing observation reports for grade X students at SMK Brahma Hardika Indonesia.
