This document discusses computer managed instruction (CMI), which uses computers to organize and manage instructional data to effectively achieve educational objectives. CMI can automate tasks like grading and scheduling to reduce instructor workload. It introduces the definitions of CMI provided by Burke and Leib, which describe CMI as using computers to systematically control instruction through testing, diagnosis, prescription, and record keeping or to aid instructors without doing the actual teaching. The document then outlines the key functions of CMI in education, such as inputting and analyzing student and curriculum data to generate reports on progress, and the advantages of CMI like tracking student performance over time.
