The function of research is to perfect the tools of education and to manufacture new ones. Research opens up perspectives and informs teachers. The whole of the education system and all its components should be investigated if research is to be comprehensive and successful. Highly qualified teams of researchers are essential, bringing a variety of interests, knowledge, and points of view. Education is a human venture and also a realm of contingencies; it is important that educational research take into account the teacher's cultural background, intellectual limitations, needs, frustrations, and the real problems faced in the classroom. Full understanding and communication between researchers and teachers must exist if change and action are to result from educational exploration, evaluation, and future planning. (JD)
