{"pk":31759,"title":"Explorations in the Parameter Space of a Model Fit to Individual Subjects' Strategies while Learning from Instructions","subtitle":null,"abstract":"In earlier work, we presented results from an empirical\nstudy that examined subjects' learning and browsing\nstrategies as they explained instructional materials to\nthemselves that were contained in a hypertext-based in-\nstructional environment. W e developed a Soar model\nthat, through parameter manipulation, simulated the\nstrategies of each individual subject in the study. In\nthis paper, w e explore the parameters of these simula-\ntions and contribute several new results. First, we show\nthat a relatively small proportion of strategies captured\na large percentage of subjects' interaction behaviors,\nsuggesting that subjects' approach to the learning task\nshared some underlying strategic commonalities. Sec-\nond, w e show that lower performing subjects employed\na high proportion of working memory intensive strate-\ngies, which m a y have partially accounted for their in-\nferior performance. Third, clusters of subjects identi-\nfied through parameters analyses continued to exhibit\nsimilar behaviors during subsequent problem solving,\nsuggesting that the clusters corresponded to genuine\nstrategy classes. Furthermore, these clusters appeju-ed\nto represent general learning and browsing strategies\nthat were, in some sense, adaptive to the task.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Submitted Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/21v5512q","frozenauthors":[{"first_name":"Margaret","middle_name":"M.","last_name":"Recker","name_suffix":"","institution":"Georgia Institute of Technology","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/31759/galley/22827/download/"}]}
