{"pk":33100,"title":"Calculation and Strategy in the Equation Solving Tutor","subtitle":null,"abstract":"This paper examines performance on an intelligent tutoring system designed to teach students in a first-year algebra class to solve simple linear equations. W e emphasize the effects of requiring students to complete low-level arithmetic operations on higher-level strategic decisions. On aX + b = c problems, students who were required to perform arithmetic became less likely to solve such problems by first dividing by a than students who were not required to perform the arithmetic required to carry out the ojjeration. The shift away from this strategy is in keeping with the predictions of ACT-R. W e discuss these results in terms of the educational implications of providing computational tools to students learning basic mathematics.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"17","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6z24z8r1","frozenauthors":[{"first_name":"Steven","middle_name":"","last_name":"Ritter","name_suffix":"","institution":"Carnegie Mellon University","department":""},{"first_name":"John","middle_name":"R.","last_name":"Anderson","name_suffix":"","institution":"Carnegie Mellon University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1995-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/33100/galley/24161/download/"}]}
