Gordon Pask Quotes

A learning strategy is comparable in kind with a performance strategy. Each sort of strategy entails decomposing goals into subgoals and applying mental subroutines to achieve the subgoals concerned. The necessary difference between learning strategies and performance is in the domain upon which they operate. Whereas the performance strategy solves problems posed by states of the (usually symbolic) environment, the learning strategy solves the problems posed by deficiencies in the current repertoire of relevant performance strategies; the solutions produced by a learning strategy are performance strategies.

Conversation Theory is a summarization of our assumptions and rationale from this early period. Conversations are behaviors, but special kinds of behaviors with hard-valued observables in the form of concept sharings, detected as "understandings." Conversations are, we believe, the first basic data of psychological, social, or educational theory. We see later that people can even have conversations with themselves. Conversations which may lead to concept sharing need not be verbal. Often they are gestural, pictorial, or mediated through a computer interface.

A [learning] style is a disposition to adopt one class of learning strategy.

By definition, a pair of inherently unmeasurable, non-stationary systems, are coupled to produce an inherently measurable stationary system.

Holists, either irredundant or redundant commit mistakes due to simple over-generalization (for example, that (β) always implies "Bushy Tail" which is true for only some subspecies) or systemic over-generalization to render the classification scheme more rational or symmetrical than it actually is (for example, falsely naming a subspecies "Bit QL" on the evidence that Q stands for "4-legged" and L stands for "Linear" together with the valid inference that a 4-legged linear creature exists. A serialst is prone to list the subspecies by examining picture cards in Class A. If he is to be successful, he checks the relevance of the information entering his list by forming single predicate hypotheses.

If cognitive processes can be realized in a general machine then it is possible to execute mental operations in artifacts that are not necessarily subject to the embarrassing spatio-temporal limitations and structural frailties of a biological processor.

[A serialist]... checks the relevance of the information entering his list by forming single predicate hypotheses .... A structure is built up in orderly stages.

To summarize the matter, teaching systems ought to be conversational in form and so devised that strategies are matched to individual competence.

There are two subcategories of holist called irredundant holists and redundant holists. Students of both types image an entire system of facts or principles. Though an irredundant holist’s image is rightly interconnected, it contains only relevant and essential constitents. In contrast, redundant holists entertain images that contain logically irrelevant or overspecific material, commonly derived from data used to "enrich" the curriculum, and these students embed the salient facts and principles in a network of redundant items. Though logically irrelevant, the items in question are of great psychological importance to a "redundant holist", since he uses them to access, retain and manipulate whatever he was originally required to learn.

Given a realistically sized task (and assuming that he cannot already perform it), a student is unable to generate the required performance strategy all at once. Instead, he directs his attention to various facets or subtasks and musters subroutines that build up a performance strategy bit by bit. The process is carried out by a learning strategy which, in the free learning subject, may be innate or acquired and which, for the student, is imposed externally by a teacher or learning system.

Man is always aiming to achieve some goal and he is always looking for new goals.

Since human beings are highly adaptable it may be possible for an individual with any sort of competence to learn, in the end, according to any teaching strategy. But the experiments show, very clearly indeed, that the rate, quality and durability of learning is crucially dependent upon whether or not the teaching strategy is of a sort that suits the individual

It seems to me that the notion of machine that was current in the course of the Industrial Revolution – and which we might have inherited – is a notion, essentially, of a machine without goal, it had no goal ‘of’, it had a goal ‘for’. And this gradually developed into the notion of machines with goals ‘of’, like thermostats, which I might begin to object to because they might compete with me. Now we’ve got the notion of a machine with an underspecified goal, the system that evolves. This is a new notion, nothing like the notion of machines that was current in the Industrial Revolution, absolutely nothing like it. It is, if you like, a much more biological notion, maybe I’m wrong to call such a thing a machine; I gave that label to it because I like to realise things as artifacts, but you might not call the system a machine, you might call it something else.

We now come to the underpinning contention of the previous monograph. Psychological phenomena, especially those involved in learning and education, stem from or are related to states of consciousness. Using the argument which relates the information available about conscious processes to the type of experimental situation, we maintain that the basic unit of psychological /educational observation is a conversation. In order to test hypotheses and explicate the conversational transactions, it is necessary to invoke various tools and explanatory constructs. These are coherent enough to count when interlocked as a theory, and this theory was dubbed conversation theory.

The' holist/serialist' distinction (Daniel, 1975; Pask and Scott, 1971, 1972) is an example of different learning strategies, rather than the more generally exhibited learning style. The holist or serialist strategies are exhibited in a , strict conversation,' and are thus insufficiently refined to account for learning in general. Holism and serialism appear to be extreme manifestations of more fundamental processes, which are induced by systematic enforcement of the requirement for understanding which is as strong as, or stronger than, the requirement for' deep-level' processing.
