1. How have ill-defined problems and ill-defined domains been described in other research? (answers to this question appear under the major subheadings on pages 255-258). - Reitman (1964, 1965) stated that an ill-defined problems is one where one of the problem components is missing or left unspecified, also called open-textured. Open-textured - application (to act on it) is not automatic but requires judgement and is context dependent). O.T are common in ill-defined domains (ex. law and music; it’s all “open-ended”). - Voss (2006; Voss et al., 1983) - focused on human problem solvers (the expert and the novice) - listed characteristics of ill-defined problems, including - having vaguely stated goals - no unambiguous right/wrong answers

Must apply relevant knowledge to achieve those goals. Ill-defined problems are when variables such as concepts, relations, or solution criteria are left unspecified, requiring the problem solver to recharacterize it —> the resulting solution may be up for debate (i.e. perspective; the variables that the problem solver fill the blanks in with may not be ok with others, who want to do another something else with the given problem). Domains are defined as conceptual spaces or fields of study. They are the structural knowledge, techniques, principles, etc. that are relevant to the issue (pretty much anything relevant to the problem, implicitly or explicitly). Ill-defined domains lack a single strong domain theory specifying the essential concepts, relationships and procedures for the domain. Recharacterization is required when working to solve the problem. Some features of ill-defined domain are that the concepts or theories relating to the problem aren’t well accepted or is incomplete (such as fashion; “in” one day and “out” the …show more content…
Define the concept of recharacterization. - Recharacterization - transforming the open constraints by filling in the missing problem components. This allows for a better defined and more solvable problem. ***Problems where there are missing variables for the complete picture, as the problem solver, we must fill in the blank and roll with what we have.
4. Why is recharacterization an important and necessary component of solving ill-defined problems? (consider how “recharacterization” might be similar to “representing the problem space) - If there’s no specification to how the problem must be solve, and there are one too many options, and each options lead to a different solution, it may not be productive or efficient to try each ones of them. Therefore, restricting “area of damage” to a certain domain can generate new goals, and even little problems that area easier to solve.
5. Why do some well-defined problems seem like ill-defined problems to novices? Alternatively, consider how developing knowledge, skills, and strategies (i.e., expertise) can enable people to solve more difficult problems. - Lack of experience and/or knowledge in the domain relating to the issue at
