  • Theory of Problem Solving
    Available online at www.sciencedirect.com ScienceDirect Procedia - Social and Behavioral Sciences 174 ( 2015 ) 2798 – 2805 INTE 2014 Theory of problem solving Jiří Dostál* Palacký University, Žižkovo náměstí 5, 77140 Olomouc bSecond affiliation, Address, City and Postcode, Country Abstract The article reacts on the works of the leading theorists in the fields of psychology focusing on the theory of problem solving. It contains an analysis of already published knowledge, compares it and evaluates it critically in order to create a basis that is corresponding to the current state of cognition. In its introductory part, it pursues a term problem and its definition. Furthermore, it pursues the problematic situations and circumstances that accompany the particular problem and appear during its solving. The main part of this article is an analysis of the problem solving process itself. It specifies related terms in detail, e.g. the ability to perceive the problem, the perceptibility of the problem, the willingness to solve the problem, the awareness of existence of the problem or strategies of problem solving. Published knowledge is applicable not only in fields of psychology, but also in fields of pedagogy, or education. © 20152014 The The Authors. Authors. Published Published by byElsevier Elsevier Ltd.

The underlying paradigm is briefly outlined together with the method- olgy used to classify individuals style. The results of a series of experiments ex- amining the implications of cognitive style are summarized; these focus on career preferences and personality factors. The body of the paper describes an experiment using a distinctive, small sample of student subjects, which examines in detail the processes of problem-solving. The experiment focuses on the relation between cognitive style and: a) problem-choice and performance b) strategies of problem-solving c) characteristics of verbalization and structure of argument Some generalizations (and speculations) are drawn from the experiments concerning aspects of management practice where differences in cognitive style seem especially important: a) communication and mutual understanding b) the design of work teams c) the design and use of decision aids, especially computer-based models.

  • Profiling a Mind Map User: a Descriptive Appraisal
    Journal of Instructional Pedagogies Profiling a mind map user: a descriptive appraisal Joanne M. Tucker Shippensburg University of Pennsylvania Gary R. Armstrong Shippensburg University of Pennsylvania Victor J. Massad Kutztown University of Pennsylvania Abstract Whether created manually or through the use of software, a non -linear information organization framework known as mind mapping offers an alternative method for capturing thoughts, ideas and information to lin ear thinking modes, such as outlining. Mind mapping is used in education, government and business as a creative method that is useful in training, brainstorming, organizing and problem solving. This paper examines mind mapping techniques, advantages and di sadvantages of hand -drawn maps and using mind mapping software. Several mind-mapping software applications are compared on a number of product dimensions. Survey results provide a descriptive profile of mind map users in education, government and business sectors. Keywords: mind mapping, mind mapping software, mind map user profile Profiling a mind map user, Page 1 Journal of Instructional Pedagogies Introduction to Mind Maps The mind mapping technique, along with the term “mind map,” originated with popular psychology author Tony Buzan (1970), who developed the technique as a way of helping people to learn more effectively. His work is partly based on the pioneering brain research of the 50’s as well as left/right brain work by Roger Wolcott Sperry (1968) which was later refined by Robert Ornstein (1977). The bod y of this research indicates that the human brain responds best to key words, images, colors, and direct association. Buzan refined these ideas into a simple set of rules that can be followed to create a maze of information known as a mind map.

  • The Pedagogy of Form Versus Function for Industrial Design
    The Pedagogy of Form versus Function for Industrial Design David Domermuth, Ph.D. Abstract – Industrial Design is a combination of science and art. Determining the balance of the two is a preeminent challenge for teachers. The function is dominated by science/engineering principles while the form is an artistic/aesthetic expression. The teacher has a limited number of courses to present the foundational material while leaving enough courses to practice designing. This paper presents an objective summary of foundational courses, programs of study from various institutions, program evaluations by industrial experts, and a discussion about predetermining student success. A summary of accreditation requirements and how they affect the programs of study is also included. Keywords: Industrial Design, program of study, form versus function, accreditation, right/left brain. INTRODUCTION The concept of art is well accepted as shapes or drawings that are created to please sight or touch. Many times art is described as a pleasing design but the work of scientists and engineers is also referred to as a plan or design, such as the design of an engine or piping system. Scientists and engineers use the word design as noun to name a device or an adjective to describe the effectiveness of a system. The term design is also used to describe a number of professional fields such as Industrial, Interior, and Architectural Design. In this sense the word design blends both meanings of art and function. “Design is often viewed as a more rigorous form of art, or art with a clearly defined purpose” [Wikipedia, 1] “In the late 1910s, the two principles of “form follows function” and “ornament is a crime” were effectively adopted by the designers of the Bauhaus and applied to the production of everyday objects like chairs, bed frames, toothbrushes, tunics, and teapots.” (Wikipedia 2008) This paper concentrates on the university training of Industrial Designers/Product Designers with respect to form and function.

Department of Education P.U. Problem Solving Method Objective : After going through this topic, students will be able to : Understand the concept of Problem Solving Method Analyse the process of Problem Solving Method Content Introduction Meaning Objectives Steps Teacher’s Role Advantage Disadvantage Introduction Problem-solving skills are necessary in all areas of life, and classroom problem solving activities can be a great way to get students prepped and ready to solve real problems in real life scenarios. Whether in school, work or in their social relationships, the ability to critically analyze a problem, map out all its elements and then prepare a workable solution is one of the most valuable skills one can acquire in life. Educating your students about problem solving skills from an early age in school can be facilitated through classroom problem solving activities. Such endeavors encourage cognitive as well as social development, and can equip students with the tools they’ll need to address and solve problems throughout the rest of their lives. Meaning A problem is a task for which Problem–solving may be a purely mental difficulty or it may be physical and involve manipulation of data. , the person confronting it wants or needs to find a solution because the person has no readily available procedure for finding the solution. The person must make an attempt to find a solution. Problem solving is the act of defining a problem; determining the cause of the problem; identifying, prioritizing and selecting alternatives for a solution; and implementing a solution.

The interface combines electroencephalography (EEG) to record brain signals and transcranial magnetic stimulation (TMS) to deliver information noninvasively to the brain. The interface allows three human subjects to collaborate and solve a task using direct brain-to-brain communication. Two of the three subjects are designated as “Senders” whose brain signals are decoded using real-time EEG data analysis. The decoding process extracts each Sender’s decision about whether to rotate a block in a Tetris-like game before it is dropped to fill a line. The Senders’ decisions are transmitted via the Internet to the brain of a third subject, the “Receiver,” who cannot see the game screen.
