A survey of entering freshmen at the United States Naval Academy was made in 1970 and 1971 to find their intended major. These tentative major choices were compared with high school physics background. The sample consisted of 2,510 students from all 50 states. Tables included are physics background, percentage choosing physics major, percentage…

The test "Measurement About Science and Scientists" (Project Physics, Form 1) was prepared by choosing 101 items from the "Test on Understanding Science" and from the "Science Process Inventory" on the basis of their ability to indicate changes in students' knowledge. The method of building derived tests is described,…

The data used for this report was prepared mainly from correspondence as described in the introduction, Chapter I. The manufacture, distribution and processing of original scientific information today is considered in Chapter II. This Chapter is devoted to the tasks of establishing precise definitions of the vocabulary used in the field (e.g.…

USING RATIO METHODS OF PSYCHOPHYSICS, THE INVESTIGATOR STUDIED LOCAL AND PROFESSIONAL STATUS SYSTEMS OF TWO PHYSICS DEPARTMENTS. TO CLARIFY THE NATURE OF AND THE RELATIONSHIP BETWEEN LOCAL AND PROFESSIONAL STATUS, AND, IN TURN, THEIR RELATIONSHIP TO INFLUENCE AND SALARY, RELEVANT DATA WERE COLLECTED FROM PROFESSORS AND GRADUATE STUDENTS THROUGH…

This Rate Training Manual (RTM) and Nonresident Career Course form a self-study package for those U.S. Navy personnel who are seeking advancement in the Sonar Technician Rating. Among the requirements of the rating are the abilities to obtain and interpret underwater data, operate and maintain upkeep of sonar equipment, and interpret target and…

Presented is a unit designed for curriculum infusion and which relies on the hands-on discovery method as an instructive device. The student is introduced to the theory of a functioning salt water conductivity meter. The student explores the resistance of salt water as salinity increases and he treats the data which he has gathered,…

This is the initial publication of a series of self-study manuals on optical radiation measurement, and contains the first three chapters. Additional chapters will be published when completed. These chapters include: an introduction to optical radiation and the ray approach to its treatment; an introduction to the basic radiometric quantity…

Track and field coaching is considered an art embodying three sciences--physiology, psychology, and dynamics. It is the area of dynamics, the branch of physics that deals with the action of force on bodies, that is central to this book. Although the book does not cover the entire realm of dynamics, the laws and principles that relate directly to…

Prospective high school teachers participated in a seminar on various physics curricula taught by an instructor who was admittedly pro-Project Physics. At the end of the seminar the students as a whole had shifted their preference from a "traditional" curriculum to one with objectives resembling those of Project Physics. (MLH)

This article provides information to aid in starting a course in musical acoustics. The selection of topics for lecture, a project-mode laboratory, texts, references, equipment, and lecture demonstrations are covered. (Author/CP)

Describes a simple microwave interferometer capable of measuring small phase shifts. Proposes laboratory exercises involving the use of the interferometer in the determination of refractive indices of gases and the analysis of the reflection in a test chamber. (Author/CP)

Presents three activities: (1) the investigation of the purity and stability of nicotinamide and flavin coenzymes; (2) desk-computer fitting of a two-exponential function; and (3) an interesting and inexpensive solubility product experiment for introductory chemistry. (RH)

The evolution of a laboratory oriented undergraduate plasma physics course is described. Brief accounts of the 14 experiments utilized in the course are provided. (CP)
