This part of the School Management Handbook provides elementary school administrators with an overview of recent developments in educational technology. Particular attention is paid to information needed when selecting computers for educational purposes. The first section considers the role of educational technology in general and touches on the implications of today's technological revolution. Focusing on the use of video, section 2 notes new methods for resolving the old problems of fixed broadcast schedules and inadequate program quality, then discusses the potential roles of videotape and videodiscs in education. Section 3 analyzes the place of calculators in the classroom, recounting the objections to calculator use and describing the educational functions of calculators, supportive materials, teacher preparation, and calculator selection considerations. The last three sections treat computers in education, covering such topics as software and courseware selection, educational uses for computers, computer languages, computer literacy, teacher involvement in computer oriented education, computer hardware, the basic parts of the computer, computer memory, administrative uses of computers, and computer peripherals such as storage devices, printers, intermachine communications equipment, and sound equipment. Each section of the document includes recommendations for school policy on using and selecting technological devices and materials. (PGD)
