Gordon Pask’s Conversation Theory: A Domain Independent Constructivist Model of Human Knowing. Bernard Scott. Centre for Educational Technology and . The model in question is partof the conversation theory (CT) of Gordon Pask. CT, as a theory of theory construction andcommunication, has particular relevance. Since then a substantial percentage of the software development of my career has been guided by Conversation Theory and the work of Gordon Pask.

Lp was Pask’s protolanguage which produced operators like Ap which concurrently executes Conthe concept of a Topic, Tto produce a Description, D. When I met Pask I was working on problems of software user interface design.

The Derivation of a concept from at least two concurrently existing topics or concepts. A goal-directed system, and one which learned, and which could be constructed as an artifact, seemed somehow sublime.

This page was last edited on 1 Novemberat Typically for any Paskian adventure, the answer was yes and no. Other published papers 23 have succeeded in clearly expressing this architecture. He proposed a rigorous model of analogy relations.

Conversation theory

A residue of xonversation interaction may be captured as an “entailment mesh”, an organized and publicly available collection of resultant knowledge, itself a major product of the theory as devotees argue they afford many advantages over semantic networks and other, less formalized and non-experimentally based “representations of knowledge”.


Back This software system is described in Pangaro, P. His wish was to develop a social cybernetics that would cnversation combat terrorism, oppression, and social conflict.

Just as the stories above provide only a partial review of the systems described, mention of a further application for Conversation Theory can only sketch its value. Because they were about the production and reproduction of concepts, entailment meshes could provide a dynamic model of what it means to know something: My interest was raised with each encounter.

The User History consists of, among other details, a record of terms used by the user and the system, topics and gotdon shown and the current context of conversation.

Example PaskChapter 9 discusses the application of conversation theory to a medical diagnosis task diseases of the thyroid. Last Updated November 30th, Pask found these points to be the understandings which arise in the conversations between two participating individuals, and which he defined rigorously.

Certain classes were de rigueur no matter what your primary discipline or interest. In Cybernetic Serendipityed.

The color of the sky is blue. For example, these classes may represent a particular range: The color of the sky is red. Then I heard about Jerry Lettvin, an M. Undergraduate Times I entered the field of cybernetics as everyone does, as an observer of my own thinking.

Pask originated from a cybernetics framework and attempts to explain learning in both living organisms and machines. Taking advantage of entailment meshes to produce the above features of adaptive, personalized training is not surprising, given their heritage in cognitive modelling and learning style research. The result is more directed for the user and hence more efficient and satisfying.


For teachers, the explicit connversation of the subject matter facilitates student understanding e.

Conversation theory applies to the learning of any subject matter. They lectured in tag-team format, one of them punching out an idea until it was on the ropes, then the cohversation guy stepping in to take care of the next one.

A primary authoring activity is that of composing prose explanations. Conversation, Cognition, and Learning. Some define it as the science of communication and control in the animal and the machine, or the communication within an observer and gordonn the observer and his environment. You could only love the ideas that came from him, because they caressed your thinking. My point cinversation is that, if taken seriously as a modeling tool for systems such as corporations and families and project teams, this architecture of conversations could become the basis of an innovation in software.
