As a profession and area of academic study, Instructional Technology is not all that intuitively obvious a subject area. The Association for Educational Communications and Technology (AECT) presented a working definition in 1977, but by 1994 it needed to be reworked to account for the procedural and technological possibilities projected into the future. This volume addresses those revisions. Detailed with extensive diagrams, indices, glossary and references, this reference represents the state of the art leading into the 21st century.  xx + 186pp.
