In Korea grammar-translation method has been dominant in teaching English for several decades. But these days grammar teaching has been neglected because Korean students could not communicate appropriately even though they knew a good deal about the English language. Even so, in Korean EFL situation where the amount of exposure and the type of exposure are not so sufficient and students have limited teaching time and the setting, a degree of appropriate grammar teaching will be necessary. In addition, a cognitive approach which adds communicative activities to the traditional grammar teaching will be a good substitute for the grammar lesson. In this paper I suggest that guided participatory method will be the best grammar teaching method in that teachers and learners collaborate on grammar explanation.
