Application of Cooperative Learning Model Type of Investigation Group in Biology Learning Class XI of Setia High School in Mentawai Islands Regency

Abstrak

The background of this study was found that the interaction between teachers and students, and also between students and other students is very rare. This makes students become bored in learning. In addition, found in biology learning teachers do not improve students' creativity. The tendency to use lectures in front of the class still dominates the learning strategies that are used vary, so that students are less active in discussing with their peers. This is because the lecture is very practical, easily implemented by the teacher and can deliver quite a lot of teaching material.

Where two classes are taken from members of the population, which have an average value close to the same. Whereas to determine the experimental class and control class, random sampling was conducted.               The results showed that the average cognitive learning outcomes of students in the experimental class was 79.42, while the average value in the control class was 74.23. The result was 9,71> t table 2,03 at the confidence level 0,05, then H0 was rejected and H1 was accepted. It can be concluded that the results of student biology learning by using Group Investigation learning models are higher than using conventional learning models. Where there are differences in learning outcomes in the application of Group Investigation learning models in learning biology class XI Setia High School Mentawai Islands District. From the results of the t test, it is obtained t count, which is 9.71 while the t table is 2.03.    Keywords: Learning biology, Group Investigation, learning outcomes of biology
