The educational system should create conditions in which the teacher undertakes research in the classroom and then shares results which will be used in improving teaching and for teacher self-renewal. The advantages are that: (1) the teacher becomes more knowledgeable about a situation, more able to defend his or her pedagogic actions, and perhaps more influential in higher level decision making; and (2) the connection between pure and applied research is strengthened. In English for special purposes, useful teacher research could focus on the interaction between teacher, student, and materials. Research undertaken in this context could prove to be more useful in the classroom than pure research undertaken without teacher involvement. (MSE)
