I have been struggling with this same question since the 1960s when the question was "Why do Educators not employ learning research in the classroom?" The answer is in part that educators have a language and goals all their own carefully developed in Schools of Education. Educators have developed their own mythology of the teaching/learning process with only tangential shallow reference to reality. Mystery primarily as job security. Thus when they fail to teach a child to read or do arithmetic it is not their fault, and you or I couldn't possibly understand.
Richard Bloomer, thank you very much for your time and your successful response.
In it, it reflects something that many of us think, especially those who study and love teaching. There is a very distant gap between the University and the reality of schools. The sad thing, as you explain, is that in the end those affected are the educators themselves, and even more complex, the children in the educational institutions.
We have a pending challenge, for the moment as Centro APLICAE, we are detecting the myths and spreading the real evidence, in the near future to help educators and children in Latin America.
