A learning strategy is comparable in kind with a performance strategy. Each sort of strategy entails decomposing goals into subgoals and applying men… - Gordon Pask

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.

There is a theory of learning and teaching together and that is all. Results from many studies support this point of view as, also, does the evidence of commonsense. So, to be dogmatic (but with confidence) learning implies teaching and teaching implies learning. Sometimes the teacher and learner responsible for th joint process are obvious (a student at a desk and another person wearing an academic cap and gown). Sometimes, the teacher and learner are not so obviously distinct and turn out to be unexpected but, once-indicated, intuitively plausible entities.

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.
