Describes a classroom organized as a self-contained closed spaceship which provides an opportunity for individualized learning based on student interests and a chance to wrestle with the problems that would arise on an interstellar journey in a spaceship. (BR)

The relative apparent difficulty of physics concepts at the grade 11 and 12 level was examined using a questionnaire survey addressed to all physics teachers within the providence of British Columbia. The physics courses were described using 22 concepts to cover the Physics 11 course and 30 concepts to cover the Physics 12 course. Subjects were…

THIS PROJECT ESTABLISHED PLANS FOR THE ANALYSIS OF THE RESEARCH ESSENTIAL TO DEFINE AND DEMONSTRATE THE DIMENSION OF SCIENTIFIC LITERACY NEEDED BY CITIZENS IN A DEMOCRATIC SOCIETY DURING AN AGE OF RAPID SCIENTIFIC AND TECHNOLOGICAL CHANGE. THE OBJECTIVE WAS TO DETERMINE THE KINDS AND DEGREES OF COMPETENCE ESSENTIAL TO INFORMED CITIZENSHIP AND…

Three approaches to the graphic representation of similarity and dissimilarity matrices are compared and contrasted. Specifically, Kruskal's multidimensional scaling, Johnson's hierarchical clustering, and Waern's graphing techniques are employed to depict, in two dimensions, data representing the structure of a set of botanical concepts. Each of…

Included in this publication are 12 papers related to teaching chemistry in a two-year college. The papers are presented in the following topic areas: (1) Learning Theory Applied to Chemistry; (2) Some Special Problems in Chemical Education; and (3) Current Concepts in Chemical Education. (SA)

THE PURPOSE OF THIS PAPER WAS TO REVIEW HOW "AUTOMATION" IS DEFINED, GIVING CONSIDERATION TO CONVENTIONAL USAGE OF THE TERM AND TO THOSE CONSIDERATIONS WHICH DETERMINE THE CONVENIENCE OR SUITABILITY FOR RESEARCH PURPOSES OF PARTICULAR CATEGORIES OF TECHNICAL CHANGE. AN UNDERLYING ASSUMPTION IS THAT THE ADJUSTMENT DEMANDS IMPOSED BY TECHNOLOGY…

This study involved examining an instructional unit with regard to its concept content and appropriateness for its target audience. The study attempted to determine (1) what concepts are treated explicitly or implicitly, (2) whether there is a hierarchical conceptual structure within the unit, (3) what level of sophistication is required to…

This document presents a discussion of the postulated mechanism that leads to the materialization and dematerialization of matter and to antigravity. The mechanism also explains why an orbital electron does not radiate energy, in contradiction to classical electromagnetic theory. One of the paradoxes of special relativity is explained. A new model…

This report summarizes two nationwide studies conducted by the National Assessment of Educational Progress (NAEP), in 1969-70 and 1972-73, in which information was gathered on the skills and knowledge in science of respondents aged 9, 13, and 17. Included in this report are: a description of the sample used and the science exercises used;…

Astronomical fundamentals are presented in this unit of the Project Physics text for use by senior high students. The geocentric system of Ptolemy is discussed in connection with Greek concepts including Aristarchus' heliocentric hypothesis. Analyses are made of Copernicus' reexamination, leading to Tycho's observations and compromise system. A…

Mechanical theories are presented in this unit of the Project Physics text for senior high students. Collisions, Newton's laws, isolated systems, and Leibniz' concept are discussed, leading to conservation of mass and momentum. Energy conservation is analyzed in terms of mechanical energy, heat energy, steam engines, Watt's engine, Joule's…

Optical and electromagnetic fundamentals are presented in this fourth unit of the Project Physics text for use by senior high students. Development of the wave theory in the first half of the 19th Century is described to deal with optical problems at the early stage. Following explanations of electric charges and forces, field concepts are…

This guide provides a framework that may be used by local science curriculum developers to produce units of study, each representing a process of science applied to one of the conceptual schemes of science within one of the major categories of science. Examples of variants, (at ten levels of sophistication), of the 18 major concepts which result…

This report presents the procedures, results and conclusions of a study designed to compare the effectiveness of several feedback modes for correcting errors in computer-assisted instruction. Seventy-five university upperclassmen were taught 30 general science concepts by means of a computer-assisted adjunct auto-instruction program. Subjects were…

This study initiated in 1950, tested two hypotheses: (1) that as elementary school children progress through school their concepts of terms and principles in science become more correct, and (2) that elementary school children in 1964 would be more correct in their concepts of scientific terms and principles than similar children were in 1950. An…
