This publication is designed to present information to the faculty of the University of Missouri on an updated Educational Teleconference System (ETS) which operates from that campus and to encourage them to use that system in future teaching activities. Introductory materials provide a brief overview of the history of educational uses of the…

Mass communication researchers have largely ignored the role of audio media and popular music in the lives of children, yet the available evidence shows that children do listen. Extant studies yield a consistent developmental portrait of childrens' listening frequency, but there is a notable lack of programatic research over the past decade, one…

Although there is a great need for field workers in the process of social change in underdeveloped countries, there are several weaknesses in the field worker system: inadequate supply, narrow range of competence, inadequate quality control, and inflexible learning situations. In order to expand the reach and breadth of such non-formal education…

Though most technological advances are triggered by the initiative of the military and business sectors, if educators can overcome their aversion to technology, some recent technological developments can easily be adapted for use in the educational sector. For example, an experimental color television camera developed recently is no larger than a…

To obtain an overall view of the auditory training equipment used in California, 27 different models of nine makes of auditory training systems were subjected to an acoustical, quality control, and educational analysis. The test methods used were those of the hearing aid industry. An analysis of questionnaires sent to teachers, speeches by Hyman…

The trend toward greater flexibility in educational methods has led to a need for better and more rapid access to a variety of aural and audiovisual resource materials. This in turn has demanded the development of a flexible, reliable system of hardware designed to aid existing distribution methods in providing such access. The system must be…

Visitors to a public museum were asked to study a museum exhibit and to answer programed questions using a punchboard coordinated with an audio cassette. The audio portion pointed out relationships in the exhibit and directed a visitor's attention, as well as confirmed his answers to the punchboard questions. Some visitors used the audio cassette…

Detailed explanations of the studio techniques used in radio, record, television, and film sound production are presented in as non-technical language as possible. An introductory chapter discusses the physics and physiology of sound. Subsequent chapters detail standards for sound control in the studio; explain the planning and routine of a sound…

Construction and use of three pieces of equipment for preparing learning materials are described: a light viewbox for previewing slides or transparencies or tracing line drawings; a photographic copy and storage stand for photographing large specimens or copying from large charts or books; a booth for recording narrations for audiotutorial…

Discusses types of sound-production equipment used for realization of interactive audio within computer assisted instruction (CAI) environments (speech synthesis systems, and speech/sound-recording, retrieval, and playback equipment); describes several authoring systems in which sound processing plays a predominant role; and presents an overview…

Distance education is characterized, and its trends are discussed. Computer assisted tutoring, audiocassettes, videodiscs/videocassettes, and microcomputers are analyzed in terms of their interactive characteristics and their role in bettering independent study. Ten references are listed. (Author/MBR)

This article is the last of a three-part series dealing with sound measurement, effects, pollution, and indoor/door learning activities. This section focuses on outdoor activities and equipment that students can make to assist them in data collection. (Author/SA)

Various kinds of electronic information media can now be integrated to plan educational programs, through use of computer videodiscs, hypercards, and hypertexts. Discussed are the components of integrative technology, including audio technology, video technology, and electronic text and graphics, and possibilities for interfacing the various…

A study involving 17 individuals (ages 17-55) who were blind examined the use of a prototype testing system that employs synthesized speech to deliver questions on reading and listening comprehension tests. In general, the usability of the system was evaluated positively. The most serious problem was synthesized speech quality. (Contains 2…

The current study examined the impact of complainant sexual history evidence on mock jurors' judgements in a sexual assault trial. One hundred and sixty-nine undergraduates listened to an audiotape of a sexual assault trial in which the sexual history between the complainant and defendant was systematically varied to include either sexual…
