As I approach my 70th year in physics, let me tell my younger colleagues about my adventures with computation. When I was 14, my father gave me a slide rule because I appeared to be headed toward a career in physics. Since then, I have had experience with many other calculating devices.

Discusses advantages, disadvantages, specifications, and prices of video projection systems for use in training programs. (SK)

Looks at the latest tools for trainers such as laptop computers, fold-up overhead projectors, LCD panels with built-in computers, and digital converters. Suggests that these products can make training portable by combining functions in single pieces of equipment and allowing trainers to make last-minute adjustments to their programs. (JOW)

Introduces the computer projection panel, highlights the advantages and disadvantages of using it in the classroom, and suggests an integrative strategy for purchasing projection equipment. (Author)

The safety of projectors and related viewing devices for school, home, and business use is of paramount importance. The Advisory Committee on Safety (ACOS) of the International Electrotechnical Commission (IEC) has established a working group to consider the problem of projector safety and to make recommendations for safety standards. (CMV)

This article examines the cultural history of slide projection technologies by focusing upon how such technologies acquire cultural meaning. The meanings acquired by these technologies emerge in areas as diverse as public and domestic entertainment, religion, science, and education. I identify three important discursive shifts impacting the…

Describes a screen projector based on liquid crystal display (LCD) that duplicates the monitor of a microcomputer and may be used in group training sessions for demonstration purposes. Suggestions of what features to look for and a buyer's guide are provided. (CLB)

Gives suggestions for using audiovisual aids at conferences where the conditions are apt to be less than ideal. Discusses lighting, sound, overhead projectors, slides, boards and flipcharts. (JOW)

States that faculty needs for high quality projection hardware seem to cluster around three variables: brightness, mount, and cost. Discusses the many lessons learned in the purchase, installation, and maintaining of video projectors in community colleges. Suggests some Web sites to explore for assistance in purchasing the next video projector…

The author studies the effects of using educational media in training and students' fascination with the new visual techniques. He presents the changes that have occurred over the past one hundred years in the methods and techniques of teaching adults. (SSH)

The following aspects of using the overhead projector in the advanced reading class are discussed: (1) control of focus by pointing, underlining, or circling; (2) control of how much text the students read at one time; (3) use of overlays to isolate different aspects of the text; and (4) progressive processing of the text. (SW)

Critiques the use of computer-generated graphics and text in place of overhead projector transparencies in large lecture halls. Describes an experience in such a situation and suggests that colleagues can be helpful in assessing the effectiveness of educational innovations. (DDR)

Discussion of the use of computers for presentations in the classroom focuses on their use in a calculus course to explain graphs of functions. Topics discussed include the importance of managing the group process in the classroom; environmental considerations; and projectors and screens. (LRW)

Discusses the use of computers in college classrooms as presentation systems, as structured laboratories, to modify traditional lectures, and for self-paced instruction. Classroom dynamics are discussed, needed curricular modifications are considered, appropriate evaluation techniques are suggested, and problems are examined, including a lack of…
