Abstract
This research leave from the fact that performance study of Majors student of Tadris Natural Sciences Concentration Physics (IPA-FISIKA) State Islamic University Imam Bonjol. The aims of this research were: (1) Searching ability correlation between content of capability in Chemistry and religiosity. (2) Differentiating study performance by using model of Trait Treatment Interaction (TTI) between class with capable student group early is high (learner fastern) and class with student group ably early lowering (slower learner) by using method study of autodidact (learning self) and learn habit (teaching regular) added with tutorial. This research use method of quasy experiment. Technique data collecting through test and observation, Total of population counted 101 people. But, only 66 students as a sample. The research conclude : (1) The self-learning was suitable to teach for students with high capability of knowledge (faster lesrner). (2) The regular teaching + tutorial was suitable to teach for students with lower capability of knowledge (slower learner). (3) There were correlation between religiosity and capability of content (chemistry of knowledge). (4) Trait treatment interaction can be improve the capability of academic performance of students Chemistry Science.
