Reading Guide – Using Cognitive Tools to Represent Problems Skim the article in search of answers to the following questions: 1) According to the article, what are some of the possible reasons that students have difficulty transferring academic learning to real life? (See pp. 363-364) Well-structured problems Predictable, procedural solutions (v. abstracted principles) No underlying connection of problem features and domain knowledge 2) Based on the article, what are some of the characteristic differences between well-structured problems and ill-structured problems? (See pp. 362-363) Well-structured Problems Found in textbooks Well-defined initial state/problem elements Well-known goal state Constrained logic (limited number of wellorganized, predictable concepts, rules, principles, & procedures) Knowable, predictable solutions with clear links between choices and outcomes Academic exercises Ill-structured Problems Found in real life Unknown initial state/problem elements Emergent or changing goal state Uncertain logic (multiple criteria for evaluating solutions; concepts, rules, principles, & procedures needed are not always instantly evident) Multiple, unpredictable, or divergent solutions with uncertain outcomes Interpersonal exercises Both may require different cognitive skills Reading Guide for Jonassen’s Using Cognitive Tools to Represent Problems ♦ 2009 ♦ Dr. Cherice Montgomery ♦ [email protected] Reading Guide – Using Cognitive Tools to Represent Problems Reading Guide for Jonassen’s Using Cognitive Tools to Represent Problems ♦ 2009 ♦ Dr. Cherice Montgomery ♦ [email protected] Thinking Template for Using Cognitive Tools to Represent Problems Novice v.

Primary Concepts Key Principles (Big Ideas) ". . . Search for principles. Carefully separate them from the detail used to explain them. Principles are concentrated truth, packaged for application to a wide variety of circumstances. . . . It is worth great effort to organize the truth we gather to simple statements of principle" (Elder Richard G.

(Did you understand it, have a question about it, gain a sudden insight from reading it, or find it especially valuable? √ = Got it ? = Question ! = Aha! $ = Valuable “Students are generally unable to transfer problem-solving skills that they do develop to novel problems in different contexts” (Jonassen, 2003, p. 362). “Numerous studies have shown that students are unable to solve structurally identical problems because learners focus on surface features of the problems rather than on developing adequate conceptual understanding of the problem domain” (Jonassen, 2003, p. 363). “In order to be able to transfer problem-solving skills, students must construct conceptual understanding of how problems relate to domain knowledge, and doing so requires that students learn to represent their understanding in more than one way” (Jonassen, 2003, p. 364). “The more ways that learners are able to represent problems and their relations to domain knowledge, the better able they will be to transfer their skills” (Jonassen, 2003, p. 364). “When students try to understand a problem in only one way, especially when that way conveys no conceptual information about the problem, they do not understand the underlying systems in which they are working” (Jonassen, 2003, p. 364). “Problem representation is the key to problem solving among novice learners as well as experts” (Jonassen, 2003, p. 365).

Internal representations can then function, they [Kotovsky & Fallside, 1989] believe, independently of the stimulus features of the problem” (Jonassen, 2003, p. 367). “. . . individuals choose to represent problems in ways that make more sense to them . . . . That is, they translate problems from the given external representation to one that is more familiar or convenient” (Jonassen, 2003, pp. 367-368). “When learners internalize the tool, they begin to think in terms of it” (Jonassen, 2003, p. 370). “Meaningful learning requires that learners connect new ideas to prior knowledge” (Jonassen, 2003, p. 372). “Semantic networks help in organizing learners’ knowledge by integrating information into a progressively more complex conceptual framework” (Jonassen, 2003, p. 372). “It is necessary to understand the conceptual relationships among the concepts in any problem domain in order to be able to transfer any problem-solving skills developed” (Jonassen, 2003, p. 373). 3) What implications do these quotes have for language teaching and learning?
