At the level of society and educational planners, there is a widespread expectation that teachers must use creative teaching approaches to fulfill the requirements of the twenty-first century. The mere teacher-centered method mainly focuses on memorization and may not be feasible. Teachers must be aware of innovative methods of teaching. One such method is the constructivist approach. Constructivism is an approach to learning that posits individuals as active creators of their own knowledge, suggesting that reality is shaped by the learner's experiences. In the constructivist approach, knowledge is constructed by the learner under the active guidance of the teacher. Hence, teachers have to play different roles. This conceptual paper sketches the diversified roles of teachers and students in the constructivist approach.
