The Classroom Information System (CIS) is an effort to apply computer technology to the problem of managing information in the classroom to relieve teachers of clerical duties, and also to provide them with a daily account of each child's progress. There are two curricular components: a prescriptive learning program focusing on basic skills (reading, spelling, math); and an exploratory learning program consisting of art, play, conceptual games, and activities which develop social and self-management skills. Factors considered in designing the system were dialogue characteristics, response time of the computer, amount of teacher training necessary, and control of errors and system failure. The class of students in which this program was implemented is made up of 50 children from five to eight years in age, two teachers, and one instructional aide. All were given instruction in the use of the computer terminals (typewriter and television-display types) which are located in the classroom. A teacher assigns work from the prescriptive learning curriculum to each child on a weekly basis. Children may select their own activities from the exploratory component. At the end of each week, the teacher obtains the student history report from the computer and meets with the student to discuss his/her progress. Initially, more teacher time was required for CIS planning; however this decreased as they became familiar with the programs. Students learned the system quickly and have made continued progress because of immediate feedback on their work from the computer. A bibliography, flow charts and a sample student history report are included in the appendices. (JAB)
