Ill-Defined Problems

Decent Essays
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 …show more content…
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

    Both cognitive abilities are deemed necessary, yet difficult to implement effectively, (Wit, & Meyer, 2010). I feel that the answer to this dilemma could possibly be to view the problem logically then interject creativity to develop a solution. To blend the two skills simultaneously is not realistic, based on our limited capacity to process and store information. Our logical interpretation can balance our creative intuition thus developing a more comprehensive, yet practical approach in formulating a rational solution. This brings us to another controversy regarding rational versus strategic reasoning, (Wit, & Meyer, 2010).…

    When one has a tendency to become too critical and try to reflect on their practice in very much detail, this will hinder their intrinsic motivation.

    These comments, when done well, are used to answer the question of ‘why’ the code is required. They are either important to making clear the purpose behind certain sections of code, or providing a summary of the purpose behind the code to which it refers. These bits of information can be vital to explaining complicated sections which are not immediately apparent in the naming of variables and functions. Even though comments provide additional information with regard to the code itself, bad comments can obscure the code even more than not having them at all. As Martin (2012) states, bad comments “are crutches or excuses for poor code or justifications for insufficient decisions, amounting to little more than the programmer talking to himself” (p. 35).…

    In this manner, an impression of the object can be made, but deciphering the meaning of the impression is a much more difficult problem for the human mind. In fact, the distortion of the impression over time becomes an issue, since the human mind tends to form an “idea” about the impression related to their own past experiences. This distortion of the first impression is part of the devolvement of “reasoning” because the individual’s own perceptions begin to distort the reality of the event or object that was originally perceived: As to past Experience, it can be allowed to give direct and certain information of those precise objects only” (Hume para.3). Hume is effectively arguing that…

    Moreover, these negative influences are broken down into two types of barriers, which include internal and external sources. Defining Internal Barriers Now, you have a greater cognizance of what binds people from being proficient critical thinkers. However, what exactly, are internal barriers? "“Internal” will refer to barriers that originate from within you," (Ridel, 2015, p. 27). These obstacles that stem from inside ourselves, require that we learn to decipher what falls under this category, followed by modification of said barriers in which you particularly struggle with.…

    The Story Behind Case Study Research There have been some disputes about the validity and relevancy of case study research, this writing is an attempt to give a brief background on case study research. As with all classifications of research there are advantages and disadvantages found in using this method of research. Although this writing may not solve the disputes surrounding case study research. The goal is to outline the possibilities that this research can be instrumental in giving some insight into the problems that plague the human condition. Thereby, giving way to new alternatives to possibly providing solutions to these problems.…

    Anchoring denotes the tendency to make decision based on one source of information. Depending on one source limits your options and the ability to make a comprehensive decision. Framing bias denotes the tendency to make decision based on the “face value” of the situation. What is presented might not be the real/actual issue. So making decision on what is presented at time can be misleading.…

    A weakness of the research method is the unexplained inconsistency in the time period for sourcing the data as well as the definition and consistency of the dependent variable. The regression equations in Section 3.1 are particular useful to understand how the variables involved are operationalized. Moreover, the equations in-part compensate for the lack of visual model. The descriptions of the variables, dates, and sources of data in Table 1a enable the reader to understand how the research is operationalized. However, Table 1a should identify the type of variable and the model to which the variable applies.…
