One component of Pennsylvania's Science for the Seventies Project, an experimental science curriculum for elementary schools which makes extensive use of instructional television, was an evaluation which compared the effectiveness of the project to that of existing instructional programs. As part of the evaluation, a model was developed and…

The purpose of this study was to determine the relative effectiveness of three different types of visual devices in an instructional program designed to teach an understanding of selected theoretical science concepts to elementary school children. The visual devices were prepared using Bruner's three modes of representation (enactive, iconic, and…

Reported is an evaluation of the Child-Structured Learning in Science (CSLS) Curriculum using the intellectual models of Piaget and Guilford. A cognitive test instrument was designed to measure cognition of figural classes (CFC), convergent production of figural classes (NFC), evaluation of figural classes (EFC), cognition of figural relations…

An electronic simulation model was designed, constructed, and then field tested to determine student opinion of its effectiveness as an instructional aid. The model was designated as the Equilibrium System Simulator (ESS). The model was built on the principle of electrical symmetry applied to the Wheatstone bridge and was constructed from readily…

The purpose of this study was to develop and evaluate an instructional model which utilized the computer to produce individually prescribed instructional guides in physics at the secondary school level. The sample consisted of three classes. Of these, two were randomly selected to serve as the treatment groups, e.g., individualized instruction and…

The purposes of this study were twofold: (1) to test the hypothesis that a Similarity Rating Model based on a Classification Scheme of relationships between six words in physics is representative of human subjects' judgments of similarity between the six words, and (2) to test the hypothesis that the Classification Scheme could be used in a Word…

Dimensions of scientific literacy with regard to a theoretical definition were inferred for a group of science oriented persons, a group of nonscience oriented persons, and the two groups combined. Comparisons of the strength of agreement of the two groups, and of subgroups of the two groups, with the inferred dimensions were made. The sample…

The purpose of this study was to test the efficacy of a model of critical thinking ontogeny at the undergraduate levels in a four-year college. Critical thinking ability was considered relative to mental ability, academic performance, and academic preparation for college. Students (N=607) in many disciplinary areas took a battery of tests to…

A science education process model was proposed for ultimate use in research on science teaching. In this model, classroom interaction was presented as the middle component of a three-phase system. The on-going process of classroom interaction was viewed in terms of a communications model: interaction exchanges provided communications paths through…

A general methodology for cost effectiveness analysis was developed and applied to the Colorado State University library loan desk. The cost effectiveness of the existing semi-automated circulation system was compared with that of a fully manual one, based on the existing manual subsystem. Faculty users' time and computer operating costs were…

The purpose of the project described here was to devise and test a low-cost model for increasing undergraduate career information in the University of South Florida sociology department. The initial formulation of the model described information exchanges initiated by the sociology department with alumni, community organizations, and other…

This document presents an outline of a 10-year (1985-1995) library program proposal for an academic library. Six areas crucial to dealing with a changing academic library environment are analyzed as they relate to internal and external change factors. These factors, which focus on meeting the information needs of users for a new century, include:…
