Productions are assumed to rq)resent\nsituation-action elements of knowledge. The model\nviews the performance of such a knowledge element\nas the combination of affordance properties\nassociated with the element and ability properties\nassociated with an individual. Under specified\nconditions, observed behavior can be used to separate\nand quantify variables measuring situation-action\naffordances and subject abilities. A specific version\nof this model is applied to data from four studies\ninvolving the CMU Lisp Tutor.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Submitted Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/16p8w76d","frozenauthors":[{"first_name":"Peter","middle_name":"","last_name":"PiroIIi","name_suffix":"","institution":"Xerox Palo Alto Research Center and University of California, Berkeley","department":""},{"first_name":"Mark","middle_name":"","last_name":"Wilson","name_suffix":"","institution":"University of California, Berkeley","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1993-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/31754/galley/22822/download/"}]}
