Differences In The Ability Of Mathematical Communication Of Students Who Are Taught By The Method Of Elaboration And Cooperative Type Stad On The Material Logic

Abstract

The purpose of this study was to determine the use of the method of Student Teams Achievement Division (STAD) on the material of Learning mathematics with the method of Elaboration there are differences in the Ability of Mathematical Communication on the Material Logic. The population of this research there are 80 students. The sample of this research is class X-1 as an experimental class that diajarakan with STAD totaling 40 students, and the class X-2 as the control class taught by the method of Elaboration by the number of students 40 students. The average score of posttest experimental class one xe1= 5,83 with sandart deviation se1 = to 2.41, while the average score of posttest experimental class two xe27,29 with a standard deviation se2 = 2,69 . The difference score is the average value of Posttest for the experimental class two with the use of model elaboration is high compared to the score of the average value of posttest by using the cooperative model STAD of 1.46 with a standard deviation of 0.28. Based on the scores of posttest class ekaperimen one and experiment two, the obtained results of the test of significant t-test, so that the obtained value of t = 4,48 Results are in accordance with the testing criteria that H0 is accepted ttable> t> or -3,96 < 4,48. From the description above it can be concluded that there is a difference of students who are taught with STAD by the method of Elaboration on the Material Logic. Where the alternative hypothesis (Ha) is accepted and at once reject the Hypothesis of Zero ( H0) with the good category.
