THE EFFECTIVE STRATEGIES IN TEACHING GRAMMATICAL STRUCTURES OF ENGLISH BY HARLINA SAHIB Summary Teaching grammar in general, uses theoretical approaches to develop and to promote the students success in learning new information. Theoritical approach is both inductive and deductive approach developed by (Rivers and Temperley 110) and (Goner, Philips, and Walter 135). Deductive approach applied by Rivers and Temperley represents a more traditional style of teaching in that the grammatical structure or teacher-centered approach (Rivers and Teperly, 110). On the other hand, the inductive approach seems to be more modern style of teaching where the grammatical rules are presented in the real language context or learner-centered approach (Goner, Philips, and Walter, 135).
