Students need in-school mathematical experiences to build on and formalize the mathematical knowledge they gain in out-of-school situations. This paper presents illustrations from research that was conducted to better understand how mathematics practice and problem solving in everyday work situations compared to secondary students' solutions of…

Models occupy the content core of physics, and modeling is a major process for constructing and employing physics knowledge. A model is characterized by its domain, composition, structure, behavior, and organization. Problem solving is a schematic modeling process consisting of model selection, construction, validation, analysis, and deployment. A…

The paper, part of an all-day workshop, reviews research and theory on left-right hemisphere information processing and psychophysiological models on the functional organization of the brain. Hemisphericity is considered in terms of language, cognitive styles, role in education, verbal and non-verbal processing, affective concomitants, and…

This document is intended to help school psychologists promote more effective generalization of school intervention programs for education students. Concepts (including transfer of training and response generalization) are reviewed. An approach is described which analyzes problem behavior according to its major controlling variables (skills or…

The use of two management strategies by 14 liberal arts and comprehensive colleges attempting to recover from serious financial decline during 1973-1976 were studied. The adaptive model of strategy, based on resource dependence, involves managing demands in order to satisfy critical-resource providers. The constructive model of strategy, based on…

Recurring pressures for fiscal restraint threaten the existence of educational programs, such as competitive debate, which are not publicly perceived to produce worthwhile outcomes. Since debate is misunderstood and expensive, its advocates must be prepared to provide solid evidence of its benefits. Unfortunately, methodological weaknesses in…

This paper examines concepts in information-processing theory which are likely to be relevant to development and characterizes the methods and data upon which the concepts are based. Among the concepts examined are those which have slight empirical grounds. Other concepts examined are those which seem to have empirical bases but which are…

The paper is a discussion of research on direct instruction and its implications for effective instruction in verbal math problem solving for elementary learning disabled students. Characteristics and problems of conventional programs are reviewed, as are the major features and logic of direct instruction programing. Components of instructional…

Simple and complex addition problems were presented for true/false verification to 30 undergraduate students to test a general model for cognitive addition. Problems were presented on a microcomputer, with reaction time (RT) and response accuracy recorded. Models for addition were fit to average RT data using multiple regression techniques. These…

We tested human performance on the Euclidean Traveling Salesman Problem using problems with 6-50 cities. Results confirmed our earlier findings that: (a) the time of solving a problem is proportional to the number of cities, and (b) the solution error grows very slowly with the number of cities. We formulated a new version of a pyramid model. The…

A model of the core of the stuttering block is presented, based on evidence that the disorder is essentially an inappropriate, vigorous contraction of the posterior cricoarytenoid in response to the subglottal air pressures required for speech. (Author)

A re-analysis is given of the research about the influences of certain environmental factors on student achievement. The study indicates that educational process data seem to be helpful in building up an explanatory model not only on the macro systems level, but also on the classroom interaction level. (Editor)

This paper examines the topic of systematic curriculum development at the secondary level and discusses the necessary structures and conditions for conducting systematic curriculum development in Barbados. The discussion is organized into three main chapters. Chapter 1 presents a brief overview of the secondary school system in Barbados and…

To help assess the consequences of food policies, the world's food system is being assembled into models. These models should help planners evaluate the impact of food-related policies and will try to account for the interactions of all food-related supply and demand factors. (BT)
