Describes five types of activities that elementary school teachers can use to help students understand decimals. These activities use money calculations, base-10 blocks, meter sticks, calculators, and problem solving. Specific examples are provided. (MDM)

The importance of balancing content instruction with instruction in higher level thinking skills for gifted students is emphasized. The article recommends providing students with sophisticated content, relating that content to essential underlying generalizations and principles, and then concentrating on thinking skills. (SW)

Describes the difference between mediation and "mediatisation." Suggests the need for a paradigm shift away from the computational model of knowledge as pure information processing and task-centered problem solving to a more contextualist, sociointeractional, constructivist, user-centered model of cognition. (Author/AEF)

Describes a massive cultural transformation project at two Charlotte, North Carolina, elementary schools that used Deming's total quality management principles to restructure curricula according to Boyer's eight commonalities of learning. Shows how the FADE (focus, analyze, develop, and execute) model was used to develop a well-coordinated,…

Presents guidelines for helping students produce effective multimedia presentations. Topics include modeling presentations from other successful examples; evaluation criteria; solving relevant, real-life problems; purpose statements; identifying the intended audience; preparing storyboards; the use of multimedia resources; interactivity; student…

Examines how problem solving in the domain of Mendelian genetics proceeds in situations where solvers' mental models are insufficient to solve problems at hand (model-revising problem solving). The study addressed the heuristics characteristic of successful model-revising problem solving and other aspects of student model use. (LZ)

Based on the author's experiences, this article presents approaches to aid in developing interactive presentations. Galaxy and funnel methods offer more room for creativity when compared to metaphors such as step, line, and road models. Highlights include diagrams, personal narratives of advantages, disadvantages, and steps taken in creating an…

This article reviews the history of divergent thinking tests and provides a projection of current research suggesting a bright outlook for creativity tests. A model relating problem finding and problem solving is described, as are approaches to increasing test reliability. (DB)

Two scheduling problems, one involving setting up an examination schedule and the other describing traffic light problems, are modeled as colorings of graphs consisting of a set of vertices and edges. The chromatic number, the least number of colors necessary for coloring a graph, is employed in the solutions. (MDH)

Applies a theory of analogical thinking as satisfaction of multiple constraints to the use of analogies in instruction. It shows how the strengths of particularly good analogies and the weaknesses of particularly bad ones can be understood in terms of pragmatic, semantic, and structural constraints. The constraints suggest lessons for how…

Discusses ways to simulate a probability problem of interest to middle school students in which students calculate the average number of packets of trading cards purchased to obtain a complete set of cards. Simulations utilize a spinner, a table of random numbers, and a computer. Includes the BASIC program utilized in the simulation. (MDH)

Describes differences in formative evaluation techniques between instructional designers and subject matter experts. Content analysis based on think-aloud data focusing on differences in task interpretation, problem identification and revision statements, and review strategies is discussed; use of instructional systems design models by…

Describes how parents can teach children to be creative problem solvers, providing information from the University of Michigan's Future Problem Solving Program (FPSP). The FPSP model involves brainstorming subproblems, identifying important problem areas, brainstorming solutions, brainstorming criteria for evaluating ideas, evaluating solutions,…

Presents a process model developed for interaction and mathematical level raising focusing on the individual learning process and relates this model to research. The model is meant to show how level raising can be realized by allowing students to work in small groups on a mathematical problem. Contains 24 references. (Author/ASK)

Discusses the problem-based learning (PBL) model, including underlying principles and the three phases of the cyclical process: (1) problem development; (2) initiation of PBL events, inquiry, and investigation; and (3) problem solution. A case study illustrates use of PBL in an educational psychology class. A table lists sample problems for…
