In the first cycle the increase in teacher competence after classroom supervision after continuous coaching has only reached about 66.67% in the second cycle it can increase to 100%. The average score obtained after class supervision in the first cycle was 63.30 and increased in the second cycle to 83.33, meaning that there was an increase of 20.03 and the level of completeness as a group/classical in the first cycle reached 66.67% and in the second cycle increased to 100%. The results of this school action research show that coaching/assistance in the academic supervision of the principal can improve teacher performance in utilizing the problem-based cooperative learning model.]]>
