On the basis of the experience gained in a Title III project called Computer Instruction NETWORK, the author presents some guidelines for the planning and implementation of a course at the high school level dealing with computers. The guide lists the first steps to be taken in setting up such a program, describes a teacher training program, and provides help in selecting a programing language. Choosing a programing language suitable for special purpose use, such as business education or mathematical problem solving, is discussed. The factors involved in selecting computers, terminals, input equipment, a time sharing scheme, and communications devices are noted. The cost of various equipment and training devices necessary for such a program is estimated. An annotated bibliography is appended. (JY)
