Deals with the subject of laser hazards, laser hazards control, and laser safety practices in the laboratory. Describes four categories of hazards: radiative, electrical, explosive, and toxic, and explains the status of federal regulations that seek to define lazer hazards and control safety standards.

This study was designed to determine the effect of high school physics, the frequency of high school physics laboratory use, and high school mathematics background on the success of students taking first semester physics. Data were obtained from undergraduates (N=248) at Mississippi State University. The final letter grade in the first semester of…

Designed to provide easily accessible, comparative information on graduate programs and research in physics and in fields based upon the principles of physics, this directory contains descriptions of programs offered at institutions of higher learning in North America. The entries are organized geographically for institutions in the United States,…

Following discussions between Itawamba Junior College (Fulton, Mississippi) and local high school science teachers, a periodic science competition was established for students in high schools located in the college's five-county area. The first competition was held in 1983 during which students took written tests in biology, chemistry, and…

This document contains the listings for 46 computer programs which are designed to teach various concepts in chemistry and physics. Significant time was spent in writing programs in which students would input chemical and physical data from their laboratory experiments. No significant time was spent writing drill and practice programs other than…

The strength of intuitive knowledge is illustrated by the difficulty that individuals have in trying to restructure student misconceptions. In order to harness this power, intuition must be developed within the context of each new concept to be taught. An experiment with one possible approach to this instructional problem is described and…

A practice-teaching program directly related to a physics course for future elementary school teachers has been developed at the University of Washington. Described are some of the activities and the benefit of the activities to both the prospective teachers and the physics department. (RH)

The author elaborates on the thesis that much of the confusion and argument about the role of nuclear energy in meeting the energy needs of the nation and the world is caused by failure to place the known facts in perspective with respect to time, to hazards that accompany the use of energy in any form, to economics, and to ultimate limitations in…

Describes the construction of an apparatus to produce a stream of water drops of variable size and number of drops per second. (SLH)
