Presents a method to convince students that the image produced by a plane mirror is actually behind the mirror. Uses observations that the letters of an eye chart posted on a mirror are twice the size of the images of letters of an eye chart they are holding. Provides two reproducible eye charts. (MDH)

Discusses physics, earth science, and physical science concepts that are challenging for students and teachers because they are difficult to understand and demonstrate. Identifies ratio and inverse-square as a unifying-concept approach according to the National Education Standards. Supports teaching based on student-centered activities, long-term…

Examines the design and construction of a mini-sextant and its use in demonstrating Fresnel reflection, geometric optics, and several common optical techniques. A sidebar explains the basic use of the mini-sextant as a navigational tool. (WRM)

This article reports the use of a computer-based collaborative learning instruction designed to help students develop understanding of image formation by lenses. The study aims to investigate how students, working in dyads and mediated by multimedia computer-assisted learning (CAL) programs, construct shared knowledge and understanding. The…

We present a simple activity in which students measure the resolving power of their eyes. The approach can be used at various levels of sophistication with students having a wide variety of skills and scientific training. We discuss our experiences using this activity with a class of non-science majors as well as with a group of pre-engineering…

An alternative conception for the observed differences in light bulb brightness was revealed during an unguided inquiry investigation in which prospective elementary teachers placed identical bulbs in series, parallel, and combination direct current circuits. Classroom observations, document analyses, and video and audio transcriptions led to the…

Papers on the acquisition and use of computers and telecommunications systems by colleges and universities are presented ("Information Technology: Instruction Is the Issue--An Introduction"; "The 'Star Wars' Universities: Carnegie-Mellon, Brown, and M.I.T."; and "Instruction and the Computer"). The first section…

In 1962 the Optical Society of America (OSA) established the Needs in Optics Committee for the purpose of increasing the national supply of personnel trained in optics. In order to carry out this program, the problem was broken down into six tasks, one of which was concerned with Undergraduate Research Programs. The Task IV group convened more…

This booklet is a teacher's manual in a series of booklets that make up the core of a Physical Science course designed for the freshman year of college and used by teachers in the 27 colleges participating in the Thirteen College Curriculum Program. This program is a curriculum revision project in support of 13 predominantly Negro colleges and…

This is part of a series of 42 Calculus Based Physics (CBP) modules totaling about 1,000 pages. The modules include study guides, practice tests, and mastery tests for a full-year individualized course in calculus-based physics based on the Personalized System of Instruction (PSI). The units are not intended to be used without outside materials;…

In this revised edition of an earlier publication (ED 070 574), fundamentals of optical instruments on board ships are presented in this rate training manual for regular navy and naval reserve personnel. The manual includes nine chapters: Introduction; Administration and Supervision; Nature of Light; Optical Alignment Instruments; Night Vision…

The technical subject matter of this rate training manual is written for regular navy and naval reserve personnel. Responsibilities for optical shop administration, supervision, and training are discussed in detail. Metals are studied in connection with heat treating processes. Characteristics of light are analyzed to familiarize students with…

Theories and practical skills for use in optical shops are presented in this rate training manual, prepared for regular navy and naval reserve personnel. Light theories are analyzed in connection with mirrors, prisms, lenses, and basic optical systems. Following fundamentals of mechanical design and construction, maintenance procedures are studied…

The United States Training and Employment Service General Aptitude Test Battery (GATB), first published in 1947, has been included in a continuing program of research to validate the tests against success in many different occupations. The GATB consists of 12 tests which measure nine aptitudes: General Learning Ability; Verbal Aptitude; Numerical…
