THE EFFECT OF COOPERATIVE LEARNING MODEL TYPE GROUP INVESTIGATION TO STUDENT`S LEARNING OUTCOMES ON LINEAR MOTION TOPIC IN 10TH GRADE SMA SANTO THOMAS 3 MEDAN A.Y. 2014/2015

The objectives of this research is to know whether students` learning outcome by using cooperative learning model type group investigation is better than conventional learning in the subject matter linear motion in class X SMA SANTO THOMAS 3 MEDAN A.Y. 2014/2015 The research method was quasi experimental. The populations were all X IPA grade students in first semester that consist of 3 classes SMA Santo Thomas 3 Medan. The samples of this research conduct two classes and consist of 62 students; 31 from experiment class and 31 from control class and define by random cluster sampling. The results that were obtained: pre-test mean value of experiment class was 42.26 and 41.45 for control class and then post-test mean value of the experiment class was 80.48 and 64.03 was the mean value for control class. Standard deviation in pre-test were 7.62 in experiment class and 7.55 in control class and standard deviation in post-test for two classes were 6.87 and 8.89. Then; based on observation that done by observers by using observation sheet of students` affective and psychomotor. Students` affective score on last meeting of experiment and control class are 91.83 and 87.10 and students` psychomotor score on last meeting of experiment and control class are 85.01 and 80.78 . From data; concluded that there was the Effect of Cooperative Learning Model Type Group Investigation on Students` Learning Outcome on Linier Motion Topic in 10th Grade SMA Santo Thomas 3 Medan. Its conclude that learning outcome by using Cooperative Learning Model Type Group Investigation is better than by using Conventional Learning on Linier Motion Topic in 10th Grade SMA Santo Thomas 3 Medan A.Y. 2014/2015
