{"pk":32665,"title":"Changes in Self-Explanation while Learning Vector Arithmetic","subtitle":null,"abstract":"Verbal elaboration of a worked example has been shown to be helpful to learners before attempting to solve similar problems. This has been termed as the self-explanation effect. (Chi, Bassok, Lewis, Reimann & Glaser, 1989). This study examined how self-explanation changes before and after sequential problem solving rounds. We found that changes in self-explanation within an individual may affect individual performance across a series of problem solving episodes. Also, some participants appear to use the worked-out example\nas a self-generated feedback (SGF) mechanism to help with their problem solving rounds, while other participants do not. Locations or points in a worked-out example where self-explanation (elaboration) is most likely to occur for students with higher performance scores versus those with lower performance scores, is discussed. The implications of these differences for the design of a computational cognitive model are also addressed.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Long Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/0qw9d13z","frozenauthors":[{"first_name":"Troy","middle_name":"D.","last_name":"Kelley","name_suffix":"","institution":"Human Factors & Applied Cognition Program, George Mason University","department":""},{"first_name":"Irvin","middle_name":"R.","last_name":"Katz","name_suffix":"","institution":"Human Factors & Applied Cognition Program, George Mason University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1999-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/32665/galley/23728/download/"}]}
