This first in a planned five-part series on the videodisc as an instructional tool provides a basic introduction to videodisc technology and highlights features that make it a desirable educational medium. Videodiscs are compared to slide projectors, films, and videotapes, and two basic videodisc formats are explained. (LRW)

In this article, the author has taken a little excursion back in time to illustrate the importance of two vital concepts in the minds of smart IT project managers, when they begin to consider smart-classroom installations and implementations, and the technologies they will choose. Those watchwords are: "standardization" and "boring." Certainly,…

This article illustrates how the overhead projector can be used as a light source in some peculiar ways for physics demonstrations. Five examples are included: (1) Study of chromatic aberration; (2) Making giant Newton's rings; (3) Comparison of the rate of heat absorption by different surfaces; (4) Demonstration of greenhouse effect; and (5)…

Lots of things have changed since the baby boomers began overfilling postwar schoolhouses in the 1950s. The sparkling new buildings erected across the United States to handle the population surge have lost their luster, and in many cases, their functionality. This is not new information; in a 1995 General Accounting Office report, nearly half of…

The purpose of this paper is to describe a new piece of apparatus for generating stimuli for what Michotte (1963) called 'the perception of causality'. (Author)

Describes the design and use of a water-lens microprojector constructed from inexpensive materials. Provides detailed drawings of the microprojector and outlines one method for determining the magnification of lenses used. (GS)

Authors discuss their introduction to Super 8, and considerations for initiating a Super 8 film making program in a school. (Author)

Factors to be considered in purchasing various types of audiovisual equipment are outlined. (PF)

This final section of a three part article covers audiovisual furnishings, equipment, and systems not mentioned previously. (Author)

THE ROLE OF EQUIPMENT IN THE NEW TECHNOLOGIES OF INSTRUCTION WAS EXPLORED. PROJECTION EQUIPMENT DEVELOPED SINCE 1955 AS WELL AS CONCEPTS OF PLANNING, FINANCING, AND ADMINISTRATION WERE DISCUSSED. EXAMPLES OF POST-1955 IMPROVEMENTS INCLUDED (1) INCREASED LIGHT OUTPUT DUE TO NEW LIGHT SOURCES AND IMPROVED OPTICS, (2) INCREASED EASE OF OPERATION…

Although there has been previous research concerned with image size, brightness, and contrast in projection standards, the work has lacked careful conceptualization. In this study, size was measured in terms of the visual angle subtended by the material, brightness was stated in foot-lamberts, and contrast was defined as the ratio of the…

The selection of a rear projection screen for a learning carrel should take into account the viewing angle involved. In some carrels, the viewer can be seated in front of the screen (i.e., on the normal axis) since the screen is used primarily to present information. In these cases, where the screen will be viewed only from a restricted range, a…
