As has been discussed in the previous chapter, the concept of reflection is far from new and has been developed in many directions by various authors. This gives rise to the potential risk that that the concept of reflection can lack coherence. Brookfield (1995: 216) cautions that one problem with the notion of reflective practice 'is that it has become a catch-all term embracing ideologies and orientations that are often contradictory'. Smyth (1992: 285) also warns that reflection 'runs the risk of being totally evacuated of all meaning'.
