This book is designed for use in an introductory, college level course on educational technology, and no prior experience with computers or computing is assumed. The first of a series on technology in the classroom, the text provides a foundation for exploring more specific topics in greater depth. The book is divided into three components--original text, selected articles by others in the field, and activities for students. The following topics are covered: (1) the evolution of educational technology; (2) definitions of computer literacy and how computer literacy is achieved; (3) general ways in which technology can be used in teaching and how it is used in teaching language arts, science, math, social studies, foreign language and English as a second language, and visual and performing arts; (4) basic information about hardware and software; (5) emerging technologies such as videodisc, HyperCard, and interactive video; and (6) future developments in the field. A list of magazines and journals in the areas of computers, technology, and education is appended. (KRN)
