Task-based Teaching of Grammar By: V. yousefi, Ave Sina Shahed High School, Hamedan I.

They have sought ways to make the classroom more “student-centred” and have investigated the different ways in which students can play more active roles in discovering and processing knowledge. The result of the research is the outcome of task-based learning. Although task-based learning is regarded as one particular approach to implementing the broader “communicative approach” and, as with the communicative approach in general, one of the features of task-based learning that often worries teachers is that it seems to have no place for the teaching of grammar. Actually grammar is as important in a communicative approach as in any other approach. That is to say, grammar applies with equal force to task-based learning.
