The document discusses reflective practice theory, which involves reflecting on how professionals think and act in different situations. It was developed by Donald Schön and Chris Argyris to study how professionals learn. Reflective practice critiques overreliance on technical rationality and recognizes that professionals must use both research-based theories and experience/artistry to solve complex, undefined problems. It involves reflecting on one's tacit "knowing-in-action" and differences between espoused theories and actual theories-in-use to improve effectiveness.
