Compared, for selected outcomes, were integrated chemistry-physics courses with chemistry and physics courses taught separately. Three classes studying integrated Physical Science Study Committee (PSSC)-Chemical Bond Approach (CBA), and three classes studying integrated Physical Science Study Committee-Chemical Education Materials Study (CHEMS)…

Included in this study were (1) construction of a teaching unit on charge cloud atomic structure for junior high schools, and (2) testing of student achievement based upon use of this unit as compared to students using a conventional approach. A unit was constructed utilizing material judged to be appropriate at this level by a group of chemists.…

This report is based on the work of international research panels and a 1973 workshop on whether, and how, the computer could be used to enhance learning within individual disciplines in the secondary school. Eight recommendations are based on the criterion that the computer should be used in teaching only tasks that either it alone can fulfill,…

Attitudes toward science before and after an introductory college physics course were compared for 252 undergraduate students by using a 99-item science attitude survey. Attitudes were found to be favorable before and after the course, but slightly less favorable afterwards. Pre-professional student attitudes were generally favorable. (SL)

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…

Engineering mechanics is recognized as one of the core subject matter areas of most engineering and technology educational programs. The study of mechanics and particularly the applications of problem solving to rigid bodies at rest (statics) has proven to be troublesome to students. Systematic problem solving includes analysis, synthesis, and…

This report of an international conference deals with problems concerning the development and implementation of science curriculum, particularly physics. Papers and discussions of participants are included and are categorized into the following groups: (1) The Motivation and the structure of science curricula; (2) Strategies and dispositions for…

Continuing education is discussed for three physics careers: teaching, science, and industry. Opinions and recommendations from a variety of sources are summarized. An annotated bibliography is included. (MH)

This document is intended to give the secondary school teacher background information and general suggestions for teaching units and correlated learning activities related to energy and energy conservation. Sections are directed to: A Problem Shared by All, Causes, What is Energy?, Energy Sources, Searching for Solutions, Conservation: An Ethic…

The purposes of this study were: (1) to evaluate the effectiveness of audio-tutorial (A-T) instruction and (2) to identify, classify and study differences in problem solving approach using a theoretical framework derived from the ideas of D. P. Ausubel. Seventy of 420 students taking a college introductory non-calculus physics course used A-T…

This report describes a nationally coordinated program development project whose purpose was to catalyze the implementation of needed postsecondary educational programs in the field of nuclear medicine technology (NMT). The NMT project was carried out during the six year period 1968-74 in cooperation with more than 36 community/junior colleges and…

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…

Described is a follow-up study to identify the objectives for science teaching measured by a sample of current editions of four standardized physics achievement tests. The methodology employed for the study is described. The findings of the study pointed to several changes. Among these were the attention given, at least by some of these tests, to…
