Answer:
constructivist
Explanation:
Constructivist approach refers to the construction of knowledge by the learners on the basis of his/her prior experience. Being a child-centric approach it stresses that children are active participants of learning who create their own knowledge based on their previous learning. This approach is rooted in the studies of Jean Piaget's theory of cognitive development.
As per the question the teacher allows the students to actively take part in real-life situations therefore it should be called a constructive approach.
