Analogical Problem Solving: The Differential Impact of Type of Training, Amount of Practice, and Type of Analogy On Spontaneous Transfer

Ives, Dune E. 01 May 1998 (has links)
Research on analogical problem solving has delineated several factors that impact one's ability to spontaneously generate a correct solution strategy to a target problem. These factors include, but are not limited to, type of analogy provided to subjects (i.e., partial versus complete), the level of analogical problem-solving expertise, and the absence of or type of analogical problem-solving training (i.e., teacher-generated or learner-generated) provided to learners. Recently, researchers have begun to focus on providing solvers with multiple practice opportunities and extending these opportunities over a systematically distributed period of time. When combined with analogical problem-solving training, these factors will augment the learner's ability to spontaneously generate a correct solution strategy to both complete and partial target problems. Using an experimental design, the present study examined the differential effects of type of analogue (partial versus complete), type of training (teacher-generated, learner-generated, or no training), and length of training (condensed versus extended) on novice learners' ability to spontaneously generate correct solution strategies to two target problems. Findings indicate that, on the complete target problem, regardless of training group membership, no effect over control group participants was found. Partial target problem results indicate a slight advantage for participating in the learner-generated extended training group over no training. Also on the partial target problem, a moderate advantage was found for participating in the learner-generated extended training group over the condensed training. Limitations of the study, implications for educators, and recommendations for future studies are provided.

Semantic Role Labeling with Analogical Modeling

Casbeer, Warren C. 14 July 2008 (has links) (PDF)
Semantic role labeling has become a popular natural language processing task in recent years. A number of conferences have addressed this task for the English language and many different approaches have been applied to the task. In particular, some have used a memory-based learning approach. This thesis further develops the memory-based learning approach to semantic role labeling through the use of analogical modeling of language. Data for this task were taken from a previous conference (CoNLL-2005) so that a direct comparison could be made with other algorithms that attempted to solve this task. It will be shown here that the current approach is able to closely compare to other memory-based learning systems on the same task. Future work is also addressed.

Design Simplification by Analogical Reasoning

Balazs, Marton E. 09 February 2000 (has links)
Ever since artifacts have been produced, improving them has been a common human activity. Improving an artifact refers to modifying it such that it will be either easier to produce, or easier to use, or easier to fix, or easier to maintain, and so on. In all of these cases, "easier" means fewer resources are required for those processes. While 'resources' is a general measure, which can ultimately be expressed by some measure of cost (such as time or money), we believe that at the core of many improvements is the notion of reduction of complexity, or in other words, simplification. This talk presents our research on performing design simplification using analogical reasoning. We first define the simplification problem as the problem of reducing the complexity of an artefact from a given point of view. We propose that a point of view from which the complexity of an artefact can be measured consists of a context, an aspect and a measure. Next, we describe an approach to solving simplification problems by goal-directed analogical reasoning, as our implementation of this approach. Finally, we present some experimental results obtained with the system. The research presented in this dissertation is significant as it focuses on the intersection of a number of important, active research areas - analogical reasoning, functional representation, functional reasoning, simplification, and the general area of AI in Design.

Integrating Problem Solvers from Analogous Markets in New Product Ideation

Franke, Nikolaus, Poetz, Marion K., Schreier, Martin January 2014 (has links) (PDF)
Who provides better inputs to new product ideation tasks: problem solvers with expertise in the area for which new products are to be developed, or problem solvers from "analogous" markets that are distant but share an analogous problem or need? Conventional wisdom appears to suggest that target market expertise is indispensable, which is why most managers searching for new ideas tend to stay within their own market context even when they do search outside their firms' boundaries. However, in a unique symmetric experiment that isolates the effect of market origin, we find evidence for the opposite: Although solutions provided by problem solvers from analogous markets show lower potential for immediate use, they demonstrate substantially higher levels of novelty. Also compared to established novelty drivers, this effect appears highly relevant from a managerial perspective: we find that including problem solvers from analogous markets vs. the target market accounts for almost two thirds of the well-known effect of involving lead users instead of average problem solvers. This effect is further amplified when the analogous distance between the markets increases, i.e., when searching in far vs. near analogous markets. Finally, results indicate that the analogous market effect is particularly strong in the upper tail of the novelty distribution, which again underscores the effect's practical importance. All this suggests that it might pay to systematically search across firm-external sources of innovation that were formerly out of scope for most managers. (authors' abstract)

What basic emotions are experienced in bipolar disorder and how are they are regulated

Carolan, Louise January 2009 (has links)
Introduction: There remains a lack of theoretical models which can adequately account for the key features of bipolar disorders (Power, 2005). Objectives: Firstly, to test the predictions made by the SPAARS model that mania is predominantly characterised by the coupling of happiness with anger, while depression (unipolar and bipolar) primarily comprises of a coupling between sadness and disgust. Secondly, to investigate and compare the coping strategies employed to regulate positive and negative emotion between bipolar, unipolar and control groups. Design: A cross sectional design was employed to examine the differences within and between the bipolar, unipolar and control groups in the emotions experienced and the strategies used to regulate emotion. Data were analysed using ANOVAs. Method: Psychiatric diagnoses in the clinical groups were confirmed using the SCID. Current mood state was measured using the BDI-II, STAI and the MAS. The Basic Emotion Scale was used to explore the emotional profiles and the Regulation of Emotion Questionnaire was used to measure coping strategies. Results: The results confirmed the predictions made by the SPAARS model about the emotions in mania and depression. Elevated levels of disgust were also found in the bipolar group generally. The clinical groups used internal dysfunctional strategies more often than the controls for negative emotion. The bipolar group used external dysfunctional strategies more frequently than the controls for positive emotion. Conclusion: The results support the predictions made by the SPAARS model and suggest that disgust plays a key role in bipolar disorder. Strengths and limitations are discussed and suggestions for future research are explored.

Education by Metaphor

Lockett, Michael 20 February 2013 (has links)
What is metaphor and how do we learn to think analogically? Education by Metaphor explores these questions from two perspectives: poetics and curriculum theorizing. Through this discursive inquiry, I develop arguments and hypotheses on the origins, mechanics, and educative possibilities of metaphor, often by drawing from Zwicky’s philosophical work and interviews I conducted with six Canadian writers. I sought conversations with these writers because the works they publish display deft and provocative analogical play. I wanted to know what they know about metaphor, and how they came to know such things, and how these ideas inform their critical, artistic, and pedagogical practices. I also asked for their thoughts on particular discursive conflicts and metaphoric models, and I asked them about their curricular experiences, both formal and otherwise. Excerpts from these transcripts are interwoven throughout the manuscript, according to their connections with the topics at hand. The first chapter of this dissertation traces metaphor’s discursive history and delineates its conflict with philosophy. From that foundation, I critique contemporary models for metaphor that stem from Black’s and Richards’ theorizing; after explaining why they are ill-suited to poetic terrain, I develop a less reductive model. Much of this work informs subsequent chapters, hence its preliminary positioning. In the second chapter I approach metaphor anthropologically and advance hypotheses for how we, as a species, might have come to think metaphorically. These hypotheses emphasize empathy and anthropomorphism, two important notions nested within the inner-workings of analogical thought. In turn, these hypotheses inform the third chapter’s explorations of poetic and ontological attention. This theoretical work reveals concepts integrally related to metaphor’s emergence, for example aesthetic experience, defamiliarization, and the interplay of pattern and anomaly. In the fourth chapter, I revisit these concepts from a more empirical perspective and use comments from my interviewees to illuminate intersections amongst play, pedagogy, and analogical thought. Lastly, the fifth chapter asks, what good is the study of metaphor? I respond to this question by addressing metaphor’s imaginative, ethical, and educational consequences. / Thesis (Ph.D, Education) -- Queen's University, 2013-02-19 12:13:38.213

O pensamento analógico e afeto na atribuição de significados em matemática / Analogical thought and affection in the attribution of meanings in mathematics

Isabel Pereira dos Santos 13 November 2014 (has links)
Este trabalho discute o papel do pensamento analógico e da afetividade na atribuição de significados e compreensão de conceitos no processo de ensino e aprendizagem em Matemática sob a perspectiva teórica. O uso de analogia em educação coloca em evidência relações estruturais entre elementos similares de domínios diferentes, enriquecendo o entendimento dos conteúdos abordados. Neste contexto, estudou-se a Heurística e em particular o caráter heurístico da analogia em resolução de problemas, o que releva ainda a relação entre tal forma de raciocínio e o conceito de similaridade em atribuição de significados no universo educacional matemático. Por fim, o presente trabalho teorizou o tema afetividade a partir de três constructos, a saber, crenças, atitudes e emoção, visando auxiliar ações que propiciem apreensão e compreensão dos objetos matemáticos. / This research discusses the role of analogical thinking and affectivity on attribution of meaning and understanding of concepts in the teaching/learning process of mathematics from the theoretical perspective. The use of analogy in education evinces structural relations between similar elements of different domains, enriching the understanding of concepts approached in such a situation. In this context, it considers Heuristics and, in particular, heuristic features of analogies on problem solving, which also brings out the relationship between such a reasoning and the concept of similarity in attributing meanings in mathematics education contexts. Eventually, this study theorized the subject affection from three constructs, namely, beliefs, attitudes and emotion in order to support actions that encorage apprehension and understanding of mathematical objects.

UNDERGRADUATE MATHEMATICS STUDENTS’ CONNECTIONS BETWEEN THEIR GROUP HOMOMORPHISM AND LINEAR TRANSFORMATION CONCEPT IMAGES

Slye, Jeffrey 01 January 2019 (has links)
It is well documented that undergraduate students struggle with the more formal and abstract concepts of vector space theory in a first course on linear algebra. Some of these students continue on to classes in abstract algebra, where they learn about algebraic structures such as groups. It is clear to the seasoned mathematician that vector spaces are in fact groups, and so linear transformations are group homomorphisms with extra restrictions. This study explores the question of whether or not students see this connection as well. In addition, I probe the ways in which students’ stated understandings are the same or different across contexts, and how these differences may help or hinder connection making across domains. Students’ understandings are also briefly compared to those of mathematics professors in order to highlight similarities and discrepancies between reality and idealistic expectations. The data for this study primarily comes from clinical interviews with ten undergraduates and three professors. The clinical interviews contained multiple card sorts in which students expressed the connections they saw within and across the domains of linear algebra and abstract algebra, with an emphasis specifically on linear transformations and group homomorphisms. Qualitative data was analyzed using abductive reasoning through multiple rounds of coding and generating themes. Overall, I found that students ranged from having very few connections, to beginning to form connections once placed in the interview setting, to already having a well-integrated morphism schema across domains. A considerable portion of this paper explores the many and varied ways in which students succeeded and failed in making mathematically correct connections, using the language of research on analogical reasoning to frame the discussion. Of particular interest were the ways in which isomorphisms did or did not play a role in understanding both morphisms, how students did not regularly connect the concepts of matrices and linear transformations, and how vector spaces were not fully aligned with groups as algebraic structures.
