A multisensory sound lab has been developed at the Model Secondary School for the Deaf (District of Columbia). A special floor allows vibrations to be felt, and a spectrum analyzer displays frequencies and harmonics visually. The lab is used for science education, auditory training, speech therapy, music and dance instruction, and relaxation…

Reports on a study of student perceptions of learning via audioconferencing using two distinct instructional designs in university-level courses delivered at a distance. The use of field observations, interviews, focus groups, and mail surveys is discussed; pertinent literature is reviewed; and the importance of human interaction in distance…

Describes the design, development, and evaluation of an experimental two-way video teletraining (VTT) system by the Navy that consisted of two classrooms linked by a land line to enable two-way audio/video communication. Trends in communication and computer technology for training are described, and a cost analysis is included. (12 references)…

Describes a portable CD-ROM machine intended for the mass market that provides access to searchable text, graphics, and audio through a user-friendly interface. Six search modes and other system features are reviewed, and electronic texts for the unit are introduced. A table compares features of the two available models. (NRP)

Describes a mobile classroom presentation cart for multimedia technology that was designed and constructed at the University of Delaware's Instructional Technology Center. Design goals are discussed; the physical layout is explained; equipment choices are described, including computer, audio system, and projection system; and future development is…

Using sound field amplification which increased the intensity of the teacher's voice by 10 decibels, 9 primary-level children with developmental disabilities made fewer errors on a word identification task, were more relaxed, and responded more quickly than without amplification. (Author/JDD)

Despite the new possibilities that speech synthesis brings about, few Computer-Assisted Language Learning (CALL) applications integrating speech synthesis have found their way onto the market. One potential reason is that the suitability and benefits of the use of speech synthesis in CALL have not been proven. One way to do this is through…

While studying Gender Issues in Distance Education at Athabasca University, the author has read about nomadic Fulbe women in Nigeria who learned by radio. She became inspired to explore the idea of serial drama as education. She began searching the Internet for ideas. She discovered a striking example of entertainment-education--an educational…

This paper discusses common causes of problems encountered with audio systems in distance learning networks and offers practical suggestions for correcting the problems. Problems and discussions are divided into nine categories: (1) acoustics, including reverberant classrooms leading to distorted or garbled voices, as well as one-dimensional audio…

This information sheet defines teleconferencing as a meeting of three or more people at different locations by telephone and communicating via audioconferencing, audio plus graphics, slow scan television, or full motion video conferencing, and discusses some of the advantages and various applications of this technology. Three major projects that…

This article is a dialog between colleagues from different races who struggle with the complexities of doing qualitative research with participants who come from backgrounds that do not match their own. Based on transcriptions of extensive audiotaped conversations, the article explores issues related to studying across difference. The discussion…

THIS REPORT PRESENTS A BRIEF, NONTECHNICAL, PICTORIAL OVERVIEW OF THE EDUCATIONAL POTENTIAL AND APPROXIMATE COST TO CERTAIN CONFIGURATIONS OF ELECTRONIC AUDIO, AUDIO-VISUAL, AND TELEVISION TEACHING SYSTEMS. EQUIPMENT IS CATEGORIZED ACCORDING TO THE EXTENT TO WHICH PROGRESSIVE MODES OF LEARNING ARE SERVED, THE NATURE AND COMPLEXITY OF THE HARDWARE…

The terms appearing in this glossary have been specifically selected for use by educators from a larger text, which was prepared by the Commission on Definition and Terminology of the Department of Audiovisual Instruction of the National Education Association. Specialized areas covered in the glossary include audio reproduction, audiovisual…

Time-compressed speech is now being used to present recorded lectures to groups at word rates up to two and one-half times that at which they were originally spoken. This process is particularly helpful to the blind. This study investigated the intelligibility of speech processed with seven different discard intervals and at seven rates from two…

This report presents outcome data on five referrals for child-family intervention in which a new system for obtaining audio-recorded behavioral data was employed as one of several evaluation criteria. The referred child was asked to wear a radio transmitter during most of his waking hours at home during pre-intervention and termination…
