The data analysis used was an Independent Sample T-Test and N-Gain trial. The Independent Sample T-Test result showed a significant 0.000 difference from the final questionnaire average score between the control and experiment classes. The experiment class students' metacognitive awareness obtained an average score of 84.14 with the highest category and 0.433 of the N-Gain trial score belongs to the medium category. This improvement was supported by the learning implementation result of teachers and students with a very good category. This study was expected to be able to give an effective contribution for teachers to improve the biology learning quality by emphasizing on the students’ metacognitive awareness improvement.
