Over the years the educationists and psychologists have developed various methods of learning on the basis of research and experience. Generally it was believed that the learner learns mostly from trial and error. However, the Gestalt School of psychologists have come to the view that the over-all impression of a place event, or man is what affects the learner more deeply. Jean Piget has however, taken a developmental view of psychology of teaching. The teacher has to understand the child as well as the subjects he is going to teach. This book covers all these aspects of teaching and learning in a very comprehensive way.
