Constructivism

Constructivism is important in every sector learning or knowledge.
Its main idea is that, we learn with the help of our previous knowledge. It divided the learning process in to tow ways.
First one is, we learn everything by being influenced by known things, known situations, known understandings. There is no way that we can learn anything from the beginning.
Second one is, we learn actively. We learn by knowing our previous knowledge & using them as a judge.
It has important role in teaching. Teaching is not the flow of knowledge from enlightened to unenlightened. It means teachers can’t teach any one they can just guide learners they way to the knowledge. Teachers should note the prior knowledge of learners & use different situations for different learners. Teachers can ensure that learners are using then previous knowledge to build the new one. If the knowledge is actively build in present time then teacher must give time to make it strong.
Learning is a constructive process, & we need instruction to learn. So then instructions must come from a trained teacher. Teachers teach us how they are taught.
