Lauderdale, FL January, 2012 em: [email protected] web: http://www.labanca.net blog: http://problemfinding.labanca.net ph: 203.947.2850 mail: 355 Goshen Road, PO Box 909, Litchfield, CT 06759-0909 Open Inquiry Problem Finding 2 Abstract Problem finding is a creative process where individuals develop original ideas for study. Secondary science students who successfully participate in authentic open inquiry studies must engage in problem finding to determine viable and suitable topics. A multicase study examined problem finding strategies employed by highly successful students who presented a project at a regional and international science fair. Behaviors are examined through lenses of inquiry, creativity, and situated cognition. Open Inquiry Problem Finding 3 The Creative Process of Problem Finding Manifested in Open Inquiry Frank LaBanca, EdD Introduction Secondary school teachers have long valued developing student problem solving skills. Students are often challenged to use a variety of strategies to identify problems and their implications, develop action plans, utilize a variety of relevant sources, information, and data to address the problems, and formulate solutions. Problem solving techniques can be highly idiosyncratic. However, in perhaps too many educational settings involving problem solving, teachers provide students with the problem or question, and sometimes even the methodology for determining the solution. This approach may be due to curricular requirements, time factors, the limited scope and goals of particular learning modules or the inability of teachers to effectively employ inquiry-oriented instructional techniques.

I would like to thank my colleagues from the WCFIA for their generous support and for helpful discussions and comments on various aspects of this research. Abstract This paper poses that the creative search for frequently hidden “real” problems is critical if innovation aims at comprehensive system improvements and changes in thinking paradigms, rather than simple, incremental changes. These hidden real problems can perhaps best be symbolized by raw diamonds, which one strives to find in order to then grind them into sparkling diamonds, i.e. innovation. Currently, problem solving-related research focuses on the analysis and solution of predefined problems, with little emphasis on problem reframing and systemic discovery; moreover, inter- and transdisciplinary collaborations for problem finding and the application of convoluted methods receive little attention.

This paper describes an innovative design thinking process with simplified TRIZ that can be used to resolve contradictions in all domains with words such as “dilemma”, “con- flict”, “contradiction” and “paradox”. The design thinking process that have been used at d.school at Stanford and Potsdam University are popular as a human-centered innovation pro- cess with “Empathy” and “Define” stages for human-centered problem finding. However, many results may be not innovative because it uses mostly “Group brainstorming” at “Ideate” stage.

Part 1is meant to serve as a conceptual guide for those facilitating or conducting life-cycle program-management workshops focused on any of the life-cycle stages of:(1) problem finding; (2) program design; (3) program development;(4) program implementation;(5) program maintenance and improvement; and (6) program redirection. Because the framework will be amended and emended from experiences gained in the workshops and later results, the approach is termed "heuristic." A Life Cycle Guidance Team should be formed to sustain the plausibility of the program through its stages. For these purposes, a program is a theory that relates a set of organized activities and resources to intended results. Life-cycle program management and evaluation is applicable to many situations, but in this monograph it is directed toward educational operations of the Cooperative Extension System, with its many years of experience in providing educational programs. Each aspect of the life cycle is examined in some detail.

  • The Problems with Problem Solving: Reflections on the Rise, Current Status, and Possible Future of a Cognitive Research Paradigm1
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Purdue E-Pubs The Problems with Problem Solving: Reflections on the Rise, Current Status, and Possible Future of a Cognitive Research Paradigm1 Stellan Ohlssoni Abstract The research paradigm invented by Allen Newell and Herbert A. Simon in the late 1950s dominated the study of problem solving for more than three decades. But in the early 1990s, problem solving ceased to drive research on complex cognition. As part of this decline, Newell and Simon’s most innovative research practices – especially their method for inducing subjects’ strategies from verbal protocols - were abandoned. In this essay, I summarize Newell and Simon’s theoretical and methodological innovations and explain why their strategy identification method did not become a standard research tool. I argue that the method lacked a systematic way to aggregate data, and that Newell and Simon’s search for general problem solving strategies failed. Paradoxically, the theoretical vision that led them to search elsewhere for general principles led researchers away from stud- ’ ies of complex problem solving. Newell and Simon’s main enduring contribution is the theory that people solve problems via heuristic search through a problem space. This theory remains the centerpiece of our understanding of how people solve unfamiliar problems, but it is seriously incomplete. In the early 1970s, Newell and Simon suggested that the field should focus on the question where problem spaces and search strategies come from. I propose a breakdown of this overarching question into five specific research questions. Principled answers to those questions would expand the theory of heuristic search into a more complete theory of human problem solving.

Accepted 5 August, 2013 In recent years, researches had shown that the development of problem solving skill became important for education, and the educational robots are capable for promoting students not only understand the physical and mathematical concepts, but also have active and constructive learning. Meanwhile, the importance of situation in education is rising, since studies had declared that knowledge’s acquirement always occurs when people experience in a particular situation. The situation is indivisible from one’s learning activities. In this study we tried to integrate four theories: the anchored instruction which originated from the situated cognition; the web-based learning which is the main way of searching information today; the problem-based learning which focus on development of students’ problem solving skills; and the flow theory which is the best way to understand motivation. Key words: Lego mindstorms NXT robotic course, anchored instruction, active exploring, problem solving skill, flow theory. INTRODUCTION Researchers had declared that it was increasingly situation. Brown et al. (1989) had indicated that the important for teachers to help students develop skills to situation is indivisible from people’s cognition.

  • 'Putting Blinkers on a Blind Man'
    ‘Putting blinkers on a blind man’ Providing cognitive support for creative processes with environmental cues. Christensen, B. T. & Schunn, C. D. Abstract Random cues may be both beneficial and harmful to creativity. Theories of analogical transfer and association assume that cues are helpful in generating new ideas. However, theories of Path-of- least-resistance, fixation, and unconscious plagiarism say that cues can lead you into traps. Empirical research partly supports both theories. So what is a practitioner to do in selecting random cues for enhancing creativity? It is suggested that the answer is found in looking at the relationship between cues and the creative cognitive processes and their functions, and how this leads to creative outcome originality and usefulness. Two processes are examined: analogical transfer and mental simulation. It is recommended that random between-domain cues be used to increase between domain analogizing primarily with instruction to make connections, leading to product originality. Random within-domain cues should be used to increase within-domain analogizing. Due to property transfer, close analogies will have a negative impact on the originality of the outcome in problem solving instances, but to increased usefulness in problem identifying instances. Random end-user cues will lead to greater amounts of end-user simulations of usability and user preferences, and thus to higher levels of product usefulness. 1 1.Introduction Are you stuck on a creative problem, and don’t know where to go from here? Try this: In what ways might you use a stork to solve your problem? A key chain? A foreign country? Two friends? A pair of pliers? Have you solved the problem yet? Random or blind input1 into the ideational stages has long been thought to be potentially beneficial for solving creative problems.
