Conversation, Individuals and Concepts: Some Key Concepts in Gordon Pask's Interaction of Actors and Conversation Theories.

▶Purpose- Gordon Pask has left behind a voluminous scientific oeuvre in which he frequently uses technical language and a detail of argument that makes his work difficult to access except by the most dedicated of students. His ideas have also evolved over a long period. This paper provides introductions to three of Pask's key concepts: "conversations," "individuals," and "concepts." ▶Method- Based on the author's close knowledge of Pask's work, as his collaborator for ten years and as someone who has had access to and is familiar with almost all of his published work, the paper selects three of Pask's key concepts for elucidation in order to motivate the interested reader to explore Pask's work in the original. ▶Results- Pask's key concepts, "conversations," "individuals," and "concepts," which are central in his conversation theory and his later elaborations in "interaction of actors theory," are shown to be grounded in fundamental principles from cybernetics. Furthermore, the form of Pask's theorising is that of second order (reflexive) metatheorising, developing theories of theorising that explain their own form and genesis. [ABSTRACT FROM AUTHOR]
