The Effect of Cooperative Learning Model and Belief About Science On The Biology Learning Achievement By Controlling The Initial Ability Of Students (Experiment Study on Eighth Grade Students of Public Junior High School in Minahasa Regency)

The objective of this research is to investigate the effect of cooperative learning model, and the belief about science toward the achievement students’ in biology by controlling the students’ prior ability. The method used in this research is experimental with treatment by level design 2 X 2. The research was conducted at SMP Negeri 1 Tondano on 8th graders State Junior High School Students. The sample of this research are the students of SMPN I Tondano and 80 students were chosen by multistage random sampling technique. The results of the research indicate: The achievement of students which is taught by script cooperative learning model is higher than the achievement of students using STAD cooperative learning model, after controlling the students’ prior ability. The finding imply that in the biology learning, the teachers are expected to administer the cooperative learning model as the reference in teaching, by noticing the students’ belief about science.
