The document outlines the key steps and considerations in designing problem solving instruction for well-structured versus ill-structured problems. For well-structured problems, it recommends presenting conceptual models, worked examples, and practice problems with support. For ill-structured problems, it suggests articulating the context, constraints, developing case studies, supporting knowledge construction, argument building, and assessing solutions. The overall goal is to help learners effectively solve different types of problems.

Notas do Editor
Problem domain is content (concepts, rules, and principles) that defines problem elementsProblem type describes combination of concepts and rules and procedures for acting on them in order to solve problems (oxidation reactions in chemistry are type of problem that are solved in a similar manner)Problem-solving process depends on problem-solver’s understanding and representation of the type problem, including an understanding of the problem state and goal stateWith practice over time, ps-ers construct richer problem representations or schemas which they can apply in a more proceduralized or automatized manner. Experts differ from novices because their problem schemas better enable them to recognize a problem situation as belonging to a certain class of problem; novices possess deficient problem schemas and are not able to recognize problem states as well, so they rely on generalized problem-solving strategies (Sweller, 1988).Solution to problem may be convergent (single, known solution) or divergent (one of several acceptable solutions); solution should not be readily apparent so learner must identify not only the nature of the problem, but also an acceptable solution, and process for arriving at it.
Step 1: review or present prior to beginning the PS lesson; i.e. review concepts of music before solving major problemsStep 2: Provide graphic organizer to help learners construct appropriate problem representations (develop appropriate problem schema); contains representation of essential parts, states, or actions encountered in problem and relationship between them; enhances learners’ mental models of the content being studied; explicitly represents structural knowledge required to support problem solvingStep 3: Problem-solving performance improved more after studying as few as two worked examples than from solving well-structured problems; may cause issues with transferability of PS skills from viewing worked examplesStep 4: Present practice problems with worked examples; present practice problems to learner in the form in which they will be assessed (word problems on test? Then word problems during practice)Step 5: provide analogical problems; provide advice or hints; provide feedbackStep 6: what was most effective? Ineffective? Reflect in order to acquire appropriate problem schemas
Step 1: Understand context of problem; what is nature of domain? Constraints? Problems? Use activity theory (Leont’ev, 1978) to analyze task domainStep 2: What requirements might reasonably constrain their solutions?Step 3: Develop cases that represent doable real-world problems in the domainStep 4: Presents multiple representations on information; learners can compare and contrastStep 5: Provide coaching on perspectivesStep 6: Cannot try out
