John Dewey is acknowledged as a key originator in the twentieth century of the concept of reflection. He considered it to be a special form of problem solving, thinking to resolve an issue which involved active chaining, a careful ordering of ideas linking each with its predecessors. Within the process, consideration is to be given to any form of knowledge or belief involved and the grounds for its support, (Adler, 1991; Cutler, Cook & Young, 1989; Calderhead, 1989; Gilson, 1989; Farrah, 1988). His basic ideas are seminal, and indicate that reflection may be seen as an active and deliberative cognitive process, involving sequences of interconnected ideas which take account of underlying beliefs and knowledge. Reflective thinking generally addresses practical problems, allowing for doubt and perplexity before possible solutions are reached. (1995 Neville Hatton and Dr David Smith)
