The first cycle of the value of problem solving ability is still low with an average of 75.18 with a completeness of 70%. In the second cycle there was a change in the grouping of learning according to the results of reflection in cycle 1, namely the number of groups into 9 groups. In the learning process each student gets an award by using a star board so that it can increase students' motivation in learning. Learning in cycles 1 and 2 is conducted experimentally, experiments are carried out outside the classroom and it can reduce student saturation, while in cycle 2 the second meeting is conducted in biology laboratories and seating positions remain U-shaped.
