{"pk":25851,"title":"The Impact of Granularity on Worked Examples and Problem Solving","subtitle":null,"abstract":"In this paper, we explore the impact of two types of instructional\ninterventions, worked examples and problem solving, at\ntwo levels of granularity: problems and steps. This study drew\non an existing Intelligent Tutoring System (ITS) for Probability\ncalled Pyrenees and involved 266 students who were randomly\nassigned to five conditions. All students experienced\nthe same procedure, studied the same training problems in the\nsame order, and used the same ITS. The conditions differed\nonly in how the training problems were presented. Our results\nshow that when the domain content and required steps are\nstrictly equivalent, different granularities of pedagogical decisions\ncan significantly impact students’ time on task. More\nspecifically, the fine-grained step level decisions can have a\nstronger pedagogical impact than the problem-level ones.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"worked example"},{"word":"problem solving"},{"word":"faded worked\nexample"},{"word":"granularity"}],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7wm3v28k","frozenauthors":[{"first_name":"Guojing","middle_name":"","last_name":"Zhou","name_suffix":"","institution":"North Carolina State University","department":""},{"first_name":"Thomas","middle_name":"W","last_name":"Price","name_suffix":"","institution":"North Carolina State University","department":""},{"first_name":"Collin","middle_name":"","last_name":"Lynch","name_suffix":"","institution":"North Carolina State University","department":""},{"first_name":"Tiffany","middle_name":"","last_name":"Barnes","name_suffix":"","institution":"North Carolina State University","department":""},{"first_name":"Min","middle_name":"","last_name":"Chi","name_suffix":"","institution":"North Carolina State University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2015-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/25851/galley/15475/download/"}]}
