What do you think is the role of research in improving our understanding of teaching?

The role of research is to enable teachers so that they can develop essential skills in learners and improve classroom practices. When teachers research the approaches, methods, techniques and strategies of teaching and they learn how to apply them when performing a class, I think that is when the  teaching process becomes worthwhile. If teachers are not concerned about research, that means they only want to apply what another person said or thought, and in my opinion it is wrong because teachers not only have to apply what a resource says but also research more and more until they realize if  the information is effective and worthwhile. Some teachers don’t even know what teaching is, and they only base their lessons on a text book; it is really boring because learners need more than that. Learners need teachers who are able to encourage them to learning that is why teachers have to use the best ways to teach.
