This document discusses three approaches to educational technology: 1) Hardware approach (Educational Technology I) which focuses on machines and equipment like audiovisual aids and computers. 2) Software approach (Educational Technology II) which is based on theories of learning and uses instructional procedures and aids like pictures, maps, and programmed learning packages. 3) System approach (Educational Technology III) which takes a systematic view of the entire educational process and the roles of people, machines, and media within an educational system.
