Emerging research suggest that our education system must move towards learner centred curriculum and teaching methods. Following these suggestions, National Curriculum Framework (NCF) of 2005 emphasized on practicing learner centred approaches in teaching-learning i.e. constructivist approaches, and National Council for Teacher Education (NCTE) regulations 2014 suggested to make constructivist approaches based teaching-learning activities as an essential component of B.Ed. curriculum. In context to these initiatives, two important questions appear in our minds, whether those teachers already in teaching profession are familiar with constructivist approaches, and what challenges these teachers face regarding use of constructivist approaches in teaching-learning processes? Present paper tries to answer these two very important questions. The paper further presents a proposal to support awareness of teachers, and develop skills in practicing constructivist approaches based teaching-learning processes
