Communication through the modulation of electromagnetic radiation has become a foundational technique in modern technology. In this paper we discuss a modern day method of eavesdropping based upon the modulation of laser light reflected from a window pane. A simple and affordable classroom demonstration of a "laser microphone" is…

The basic concept that sound waves could be traced or recorded on a solid object was developed separately by Leon Scott, Charles Cros, and Thomas Alva Edison between 1857 and 1877 and, by 1890, the foundation of the present-day commercial record industry was established. Although cylinders were the first sound recordings to be sold commercially,…

The Newark Audio Instruction Project determined and evaluated the cost benefits and efficiency factors in using FM main channel and subchannel, the school intercom system, and audio cassettes for delivery of instructional programming for grades K-9, and developed a master plan for integrating radio/audio instruction into the curriculum. A…

Six groups of third-grade boys--three predominantly black, three white--were tested to explore three questions: whether visibility or proximity of microphones affects speech production; whether stereo recordings made from desk or wall-mounted microphones are as usable for linguistic analysis as monoaural recordings made from lavaliere microphones;…

The Highland High School (Salt Lake City, Utah) vocational television production program was designed to provide students with marketable skills in color television studio operation. Among the skills covered in the program were camera set-up and operation, video engineering, production switching, directing, television lighting, audio engineering,…

Each way to perform a particular aspect of a film production process will have its own unique effect upon the spectator--therefore, the initial task in making a film is to understand the practical techniques and use them as a base from which to develop a personal style. The technical means by which stylistic film making can be accomplished are…

Presented in this report are the results of the feasibility testing of selected micro-teaching and video recording feedback techniques in a laboratory setting designed to simulate vocational teacher education. Volunteer teachers were selected and randomly assigned to three treatment groups in a repeated measurement design to compare the relative…

The author, an associate professor of music education at Pennsylvania State University and some undergraduate music education students explored possible uses of the synthesizer as they attempted to provide experiences in electronic music for a class of fifth grade students. Their program consisted of five lessons in the elements of music which are…

A simple check list originally designed as an evaluation tool for tapes and tape series used in language instruction. The check list includes all aspects of the tape: its contents, its reference to textual material and its overall effect. There are also eight questions for the teacher's opinions. (AMH)

Factors inhibiting more widespread use of computer-assisted instruction and computer-assisted language learning include: start-up costs of computer hardware; dearth of quality courseware; skepticism regarding its effectiveness; and the educational system and the teacher. However, the promise of cost-efficiency and versatility, plus the potential…

Discusses the use of the Bank Street Laboratory sound probe in activities focusing on various aspects of sound. Also examines what students were learning during the activities (such as students understanding what is meant by the pitch of a tone). (JN)

Provides information on and evaluation of microcomputer equipment modifications for improving accessibility to the visually impaired. Equipment discussed includes input and visual output modification techniques and devices, software designed for visually impaired users, and braille output peripherals. Lists sources for available peripherals,…

Discusses the planning, preparing, assessing, and evaluation of language laboratory technology and pedagogy. (AM)

Discusses experience of using multiple media, instead of instructional television, to teach satisfactorily off-campus electrical engineering courses at Virginia Polytechnic Institute and State University. Further applications to non-engineering graduate and undergraduate courses, extension activities and short courses are recommended. (CC)

The purpose of this study was to investigate teacher control of student generated noise in a realistic university setting. (Author)
