Reflections on the conversation theory of Gordon Pask

The most satisfying and interesting human learning game‐of‐life is probably a conversation where there is a common will among the participants to promote understanding of our world despite possibly large differences in knowledge and experience. Gordon Pask took conversational learning as more than a general metaphor for humanly significant learning. He identified the essential minimal characteristics of the entities and relationships involved and formalised all that into a recursive learning theory of very broad scope. Over the years, Pask and his various System Research associates validated conversation theory by embodying it in a number of (n‐) person‐machine systems (SAKI, CASTE, THOUGHTSTICKER, TDS, etc.), and by doing case studies with various kinds of learners and tutor‐learners learning and teaching through these interfaces. Reviews some interesting aspects of conversation theory, including both its remarkable insights and some limitations. Concludes that there are good reasons for expecting that the implications of Pask’s approach to educational cybernetics will continue to be explored for many years to come.
