How can learning best be effectuated by a teacher or trainer?

How can learning best be effectuated by a teacher or trainer?  This is another very difficult question.  If there were a perfect answer, I am guessing we would not have so many learning/teaching theories.  I know from my own experience as a 'learner', I learn best when I am challenged to create or do something, rather then to merely read or hear instruction.  I think problem based learning is a very effective way to teach.  I think a teacher should be a guide, to help lead students through self discovery, and intrinsic motivation.  Having said that I believe that while teaching you should use a variety of teaching strategies/theories.   I have learned so much of behaviorism in my field of study that I can not discount it.  I believe we learn through practice, and that behaviors can be shaped through antecedents.  Teaching students with severe disabilities, I know the importance of rote practice in maintaining and acquiring skills.  I am excited to learn more about teaching theories, and to further shape my own personal theory of teaching.

As a teacher we have to find balance, and find our unique style of teaching to best serve those we teach.  Learning can be 'best effectuated' in a variety of ways. I think it is important for the teacher to consider both the content being taught and the individual students, when planning instruction.
