Perbedaan Hasil Belajar Matematika menggunakan Model Kooperatif Tipe Student Team Achievement Division (STAD) dan Model Kooperatif Tipe Group Investigation (GI) pada Siswa Kelas X SMK PGRI 2 Salatiga Tahun Pelajaran 2012/2013

This study aims to determine the differences in learning outcomes using a mathematical model of cooperative Student Team Achievement Division (STAD) and model of cooperative Group Investigation (GI). This Study is an experimental study, the research subjects were student of class X school year 2012/2013 of the two classes are in SMK PGRI 2 Salatiga. The control group in this study were students of XC SMK PGRI 2 Salatiga whose students are 32, which was treated with the model of cooperatif learning type STAD. Experimental group were students of XD SMK PGRI 2 Salatiga which totaled 31 students, who were treated with the model of cooperatif learning type GI. Ability to know the end of both groups were given the posttest. T-tes is used to determine the significance of difference in mathematics achievement between the control group and the experimental group. The results showed no differences in significant mathematics learning outcomes among students who are taunght using the STAD cooperative models with students who are taught using the model cooperative type GI. Students are taught using model cooperative type STAD gained an average of 58.75, while the students are taunght using the cooperative model type GI gained an average of 68.54. Learning outcomes in students who were taught using the model cooperative model type GI is better than the students who are using model cooperatifve type STAD
