Critical Reflection is essential to teaching as it is a means of systematic analysing of evidence through understanding of the situation and changing ideas. This active process of reflection involves problematising teaching and understanding its issues and dilemmas. It is a cyclical process which informs the next stages of learning through the development of new ideas. Reflection allows teachers to improve, explain, justify or challenge encounters in practice by combining perspectives from literature or input from peers or observations. It helps in understanding and scrutinising the teacher’s values, assumptions and perspectives. Literature can provide an alternative perspective, provide evidence to support a specific view or practice or challenge them. It is essential to personal development as it allows for analysis of what has been learnt and how it was learnt. These two functions of critical reflection are thus of great importance to professional development of teachers.
