Ideas are presented regarding: (1) unique learning activities for students who have difficulty with operations with signed numbers; (2) a mathematical inspection of a unique card trick that can be expressed as an equation; and (3) sketching of graphs of composite trigonometric functions. (MP)

A model of memory developed by information processing psychologists is described, illustrating how such a model could be used to guide science education research on learning and problem solving. (Author/SK)

Presents a model relating the adequacy of an organization's problem-solving to its resources and to the appropriateness of its structures. Describes a test of the model, on 25 public elementary and secondary schools in southeastern Michigan, which found that different organizational structures use money differently and produce different outputs.…

A model that can be effectively used to develop the notion of function and provide varied practice by using "real world" examples and concrete objects is covered. The use of Popsicle-sticks is featured, with some suggestions for tasks involving functions with one operation, two operations, and inverse operations covered. (MP)

Describes the process and outcomes of placing four disabled adults and one mother of a cerebral palsied child as teaching assistants in preschool, second- and fourth-grade classrooms in two California schools. Suggests that the employment of disabled persons in public education is an effective way of integrating special needs children into regular…

Considers the interconnection of curriculum problems and the processes by which they are treated and argues that much is to be gained by seeing curriculum problems and processes as instances of much wider sets of problems and processes generally belonging in the area of public policymaking. (Author/MLF)

Programs to help people cope with critical life events should first help them identify what information is needed and then teach them the necessary skills. Unfamiliarity with potential information sources is the greatest barrier between the individual and the source of information. (JAC)

Four major domains of research are underscored: family response to nonnormative events (e.g., wars, disasters, illness); response to normative transitions over the life span (e.g., parenthood, retirement); the importance of psychological resources and perceptions; and the importance of social support and coping with stress. (Author)

Science is shown to have unique characteristics that make it a valuable component of a basic education. While stressing the physical world, it can also provide a good model for rational and moral behavior. (JMF)

Attitudes of young adult males and their parents toward the father position were measured in a cross-generational study. Sons expected fathers to be more nurturing and recreational than parent groups. There was no difference in problem solving. Items measured what fathers should do, not what the subjects' fathers did. (Author/BEF)

Describes effects which produce the semidiurnal tidal bulges, using elementary methods, without reference to fictitious forces and without recourse to a potential. (Author/HM)

A review of the representative research and theoretical literature on right hemisphere processes and psychophysiological models regarding the functional organization of the brain is presented. (Author)

The times children take to reach correct solutions to seven easy Block Design items from the try-out version of the British Intelligence Scale were analyzed in terms of two regression models. (Editor)

Presents a dialog on the value and utility of the Person-in-Environment (PIE) System for describing, classifying, and coding common problems clients bring to social workers. Problems cited include the model's dependence on constructs with deep cultural meanings and its responsiveness to individual characteristics and needs. Advantages include…

A study of five undergraduates in an introductory course on Greek culture identified novice problem-solving patterns and cognitive processes when using Perseus, a Greek culture database. Discusses the Reading-Linking-to-Writing Model developed to capture procedural and systemic processes used in problem-solving tasks with hypermedia applications.…
