A particularly difficult area for many engineering students is the approximate nature of the relation between models and physical systems. This is notably true when the models consist of differential equations. An approach applied to this problem has been to use analog computers to assist in portraying the output of a model as it is progressively…

This booklet gives two- or three-page biographies of seventeen women scientists. They range in history from Agnodice (physician, 300 B.B.) to Jane Goodall (born 1934). In addition, brief sketches are given of twenty-three other women scientists. This anthology is intended to fill a need for curriculum materials and literature that provide positive…

This publication describes a four year, field-based program for the preparation of science teachers. It begins with a paper providing an overview of the current Iowa-UPSTEP model. A follow-up paper elaborates various facets of the model. The model integrates theory with a series of field-based clinical experiences in a four year program, providing…

In certain boundary layer or natural convection work, where a similarity transformation is valid, the equations can be reduced to a set of nonlinear ordinary differential equations. They are therefore well-suited to a fast solution on an analog/hybrid computer. This paper illustrates such usage of the analog/hybrid computer by a set of…

An explanation of strong base effect demonstrates that deprotonation of a reactant shifts an equilibrium toward reactants in the same way that a deprotonation of a product shifts it towards products. (Author/SA)

The simulation of a sampled-data system is described that uses a full parallel hybrid computer. The sampled data system simulated illustrates the proportional-integral-derivative (PID) discrete control of a continuous second-order process representing a stirred-tank. The stirred-tank is simulated using continuous analog components, while PID…

This document presents a curriculum base for a particular school system comprised of eight high schools. Its purpose is to provide a conceptual base which encourages flexibility and diversity. The format is based on the conceptual schemes identified in the NSTA publication, Theory Into Action. Included in the publication is the philosophy of the…

This guide for teacher inservice training is focused on the concept of Ekistics--the study of man in his environment. The strategies presented are based on generic inservice culminating in a management planning model, purposefully generic to all inservice and intended to add support to the personnel who would be designing inservice. The steps to…

Historically in the United States, few people with disabilities have enrolled in science-related courses or entered scientific careers in part because high schools and colleges have not offered accessible training to this population. This document is the teaching and resource guide that accompanies a 30-minute video program in career development…

This paper is addressed to the student already familiar with basic economic terms and concepts. It analyzes some existing policy alternatives by which sociopolitical units can attempt to modify environmental behavior. The primary objective of the paper is to construct a theoretical model of probabilistic effects that an effluent charge has on an…

This publication is a study guide prepared for use in a National Science Foundation (NSF) Chautaugua-Type Short Course for College Teachers. The purpose of the guide is to provide college teachers with a variety of modeling methods that can be used with problem solving. Mathematical applications and illustrations are included, along with listings…

This publication, one of a series published as a result of the Science Teacher Education Project, contains a collection of student writings for discussions to bring out some of the problems of teaching science and to reveal learning and schooling from the child's point of view. The publication is meant to be one of several resources for learning…

The development of a mathematics model to simulate small animal populations is described. Assumptions of the population model and options in the program are discussed. (MK)

Discusses the epistemology and typical applications of learning models focusing on practical methods to operationally introduce the distinctive, alloseric models into the educational environment. Alloseric learning models strive to minimize the characteristic resistance that learners typically exhibit when confronted with the need to reorganize or…

Presented is an overview and model of the proposed curriculum development process in environmental education in Connecticut. Concepts and competencies are identified at each grade level and are designed to facilitate the infusion of environmental education activities within the existing curricula using existing learning resources such as…
