Problem of teaching and development has always been a subject of interest. Does development depend on teaching or vice versa? According to Piaget, development is a spontaneous process. External actions or any interference are inadmissible as it may disturb a natural process and may be resulted into an artifact. Vygotsky had an opposite opinion. We think that Piaget’s conception is more humane. If children are forced to study and they appear at the end of their resources-this is not the most effective pedagogical approach.
