An instructional program was developed and implemented to help four first-grade students use an Atari 800 microcomputer. To determine the extent to which the four students and 40 teachers were familiar with computers and to judge their attitudes toward using them in classrooms, a survey was administered. While teachers' responses varied, all students had no previous experience with computers and were eager to use them. The instructional program was then developed to increase children's awareness of the capabilities of the computer, to increase familiarity with the operation of the computer, to assist and instruct children in programming and running programs, and to enable children to work comfortably with and instruct their peers. The program consisted of (1) pretesting students for prior knowledge; (2)instruction in terminology, operation, programming, and game playing; and (3) posttesting and evaluations. Plans were made to produce a handbook for teachers that would provide directions for operating computers and examples of simple programs. After 9 weeks of experience, the children were able to use the computer with ease. (Related materials are appended.) (Author/RH)
