A description, reanalysis, and critique of a selected portion of data reported by Elstein and colleagues is reported. Data from the study of medical diagnosis using three simulations are evaluated in terms of technical properties and consistency with a psychological model of diagnostic inquiry proposed by the researchers. (MLW)

Describes an Employee Participation Plan (EPP) involving teams of three to eight employees and a supervisor/team leader for the purpose of identifying and solving production problems and issues. Key ingredients in a successful EPP include nonauthoritarian leadership styles, thorough group leader training, and prompt action on team suggestions. (SK)

Described is a model for planning and conducting an investigation designed to teach science process skills. Use of this model illustrates the generalizability of process skills and facilitates their inclusion in novel curriculum areas and beyond the classroom. (DS)

This paper reviews current models of problem solving to identify results relevant to teachers or instructional developers. Four areas are covered: information processing models, approaches stressing human abilities and factors, creative problem solving models, and other aspects of problem solving. Part of a theme issue on intelligence. (Author/SJL)

The role of technology throughout history and its relationship to science is discussed. The new frontier of societal technology is considered in terms of human behavior and misbehavior in the face of conflict. (SA)

Examines the impact of one unit of a curriculum module for sixth grade from the Model-based Analysis and Reasoning in Science (MARS) project. Provides an overview of this unit on mass and discusses three aspects of the evaluation of the unit. Contains 22 references. (DDR)

When using spreadsheets to explore real-world problems involving periodic change, students can observe what happens at each period, generate a graph, and learn how changing the starting quantity or constants affects results. Spreadsheet lessons for high school students are presented that explore mathematical modeling, linear programming, and…

Describes the introduction of virtual, or digital, reference service at the University of New Brunswick libraries. Highlights include analyzing transcripts from LIVE (Library Information in a Virtual Environment); reference question types; ACRL (Association of College and Research Libraries) information literacy competency standards; and the Big 6…

Describes a successful course in mathematical biology at Dartmouth College. The course targets premedical students and biology majors rather than mathematics majors, and requires only one semester of calculus as prerequisite. Real world problems form the basis of student work. (Author/KHR)

Nine articles in this festschrift for Herbert Goldhor explore relatively new and innovative approaches to problem solving in libraries. The articles identify and discuss methods and techniques of applied and evaluative research, consider conceptual and practical issues related to problem solving in libraries, and recognize Goldhor's many…

Investigated the effect of the choice of a model's medium (algebraic expression or computer program) on the performance of students. Student programers did not transfer the qualities of a computer program approach to their algebraic models. Provides items for five tests. (YP)

Presents framework for collaborative problem solving between elementary school counselors and teachers. Describes factors that effect the use of the framework and the impact of the behavioral conceptual framework on teacher behavior. Strategies for counselor to collaborate with teachers in developing, implementing, and evaluating interventions is…

Seven experiments with a total of 423 three-five year olds assessed preschool children's ability to learn and transfer across problems that share a common underlying structure but differ in surface manifestations. Results are discussed in terms of explanation- or analysis-based models of both machine and human learning. (TJH)

Middle school and college students were assessed on percentage. Better students in each group were given word problems involving percentage and asked to think aloud as they solved problems. College students made more use of strategies for control and monitoring of their own procedures. A three-stage model for problem solving is then hypothesized.…

Suggests ways in which mathematical models can be presented and developed in the classroom to promote discussion, analysis, and understanding of issues related to energy consumption. Five problems deal with past trends and future projections of availability of a nonrenewable resource, natural gas. (Contains 13 references.) (MDH)
