Today we discuss about the Jean Piaget who is known for his contsructivism approach.We know that assimilation is a process whereby new information is added to the existing knowledge. Accomodation occurs when the children encounter a problem which they are not familiar and then the brain starts to struggle to fit in the new information. Nobody is born stupid, thus, all children can learnt and be taught mathematics. However, the adult around the children play very important part. As adults, when we plan lessons for the children, we must allow them to have access to their prior knowledge and then build up new knowledge. We should not be giving them the solutions at all times instead we should encourage them to solve the problem. As teachers, we need to give them more time to investigate and then share with their peers and teachers on how they solve a problem.
