Design, development, use, management and evaluation of process and resources for learning.
Instructional technology aims to promote the application of validated, practical procedures in the design and delivery of instruction. It is often defined either in terms of media and other technology used (e.g. audiovisual media and equipment and computers), or in terms of a systematic process which encompasses instructional design, development, delivery and evaluation.
