The ability to raise effective questions for problem-solving learning requires considerable skill and much preparation and practice. This research provides a brief examination of three problem-solving models for both elementary and secondary-level classrooms and emphasizes the development of an appropriate teacher question repertory for each phase…

The purpose of this paper is to identify the process for implementation of a system of positive strategy for change. In particular the Problem-Solving model for change strategy will be studied. This model will then be illustrated by its use in a systematic approach to administrative decision-making. (Author)

Administrative experimentation includes a class of heuristics for obtaining feedback on management decisions in what amounts to a continuous trial and error process.

A problem illustrating how physics and mathematics complement one another when analyzing problems of the physical world is described. (JT)

Ten functions of program theory are reviewed: contributing to social science knowledge; assisting policymakers, discriminating between theory failure and program failure, identifying the problem and target group, providing program implementation description, uncovering unintended effects, specifying intervening variables, improving formative use…

The forms and functions of imagined interaction are discussed. Imagined interaction aids in the clarification of thinking, in dealing with unfinished and emergent relationship business, in preparing for a possibly difficult interaction, and in dealing with opposing aspects of self. (Author/BL)

Presents model of algorithm design (activity in software development) based on analysis of protocols of two subjects designing three convex hull algorithms. Automation methods, methods for studying algorithm design, role of discovery in problem solving, and comparison of different designs of case study according to model are highlighted.…

Thomas Kuhn's conceptions of the influence of paradigms on the progress of science form the framework for analyzing how medical educators have approached research on medical problem solving. A new paradigm emphasizing multiple types of problems with varied solution strategies is proposed. (Author/MLW)

Organizations must recognize that training and development managers can and should play a role in organizational problem-solving. They can be quite effective in directing the jury technique of analyzing and solving unexpected contingencies. (Author)

This paper presents an analysis of high school and starting college students' work with algebraic expressions and problems involving parameters. We suggest that parameters should be considered as general numbers that are used to make second order generalizations. The Three Uses of Variable model (3UV model) is then used as theoretical framework to…

Discusses application of systems analysis to social and behavioral science as well as machine and non-machine systems. Presents rationale, principles, techniques, and advantages and disadvantages. (CJ)

Problems involving the use of diagrams to depict plangers'' (in which lines cross a specified number of times) are discussed. (LS)

Provides a solution method for the problem of finding an optimal traffic network in its simplest form where there are no congestion costs. (Author)

The Lorge-Solomon approach to group problem solving situations and its extensions to trichotomous response situations are examined by use of the maximum likelihood methods. (DG)

The conceptual approach and procedures which have been developed for this program provide the basis for initiating a similar training program in any large library within commuting distance of a library school. (4 references) (Author/NH)
