What makes constructivism more favourable theories for users of resources

Constructivism refers to the idea that learners construct knowledge for themselves. Each learner individually and socially construct meaning as he or she learns. Learners construct knowledge through learning. There is a Chinese proverb that say "Tell me and I will forget, Show me and I will remember, Involve me and I will understand. This shows that when learners are involved in their learning and construct their own knowledge, they will understand the context. Constructivism is more favourable because it explains how knowledge is constructed in the human being when this information is come in to contact with the existing knowledge that had been developed by experiences. They like it because it is limiting their role as teachers in the classroom. Their role is promoted as facilitator who cultivates interactive social environment that allow learners to personalise, exchange, collaborate, and construct heir own knowledge rather than record the knowledge. Learners are view as the constructors of knowledge that suits them. They believe that new learning depends on current understanding and facilitates effective learning for all students. Teachers allow students to play and experiment with ideas, to create, reflect and work out their own understanding. Teachers give learners opportunity to demonstrate understanding through concrete examples. Learners are seen working more than their teachers. Teachers have less work to do that is why they like this learning theory
