Written to answer the questions a teacher or administrator may have about the instructional use of computers, this book is particularly concerned with those applications of the computer in which the high school student, not a teacher or a member of the administrative staff, is "in the loop," or interacting with the computer. Acquisition of a computer capability, choice of a computer language, installation of a time-sharing system, administration of a computer terminal, and use of the computer in a mathematics classroom are topics discussed. Descriptions are given of the use of computers in various high school settings. A prose glossary of computer terms is appended. (MF)
