Pengaruh Model Pembelajaran Kooperatif Tipe Teams Assisted Individualization (Tai) Terhadap Hasil Belajar Matematika Siswa Kelas VII SMP N 3 Ujung Batu

The purpose of this research was to observe the effect of cooperative learning model Teams Assisted Individualization (TAI)) on student's mathematic learning outcomes of student of 7th grade Junior High School 3 Ujung Batu. This type of research was a Quasi experimental with design The Randomized Control Group Only Design. The population in this research were all class 7th grade Junior High School 3 Ujung Batu. Sampling was done by random sampling, so the class VII.1 selected as experimental class and the class VII.3 as a class control be sample.

Lilefors normality test on the sample test showed that the experimental class and control class normal distribution. Homogenity test with F test showed that class of homogeneos. Based on the hypothesis testing performed by t test obtained t_hitung = 15,59 and t_tabel = 2,312. This means that t_hitung>t_tabel, then H_0 is rejected. This means that there were differences between the experimental class and the control class. It can be concluded that there were effect of the application of cooperative learning model Teams Assisted Individualization (TAI) to the mathematic learning outcomes of student of 7th grade Junior High School 3 Ujung Batu
