Entries are organized in five broad categories: (1) educational technology as a concept and as a field and how it is disseminated in different ways; (2) functions such as needs assessment, design, media production, evaluation, diffusion and implementation, as the design process is highly dependent on good organization, it also includes entries on management of educational technology and on resources frequently used by educational technologists; (3) strategies, techniques, materials and devices to deliver technology; (4) applications of educational technology in institutional settings; and (5) emerging issues in the field.
This volume includes entries from the highly acclaimed International Encyclopedia of Education, 2nd Edition (described by Choice as being "a premier resource when judged on virtually every criteria applied to a reference work"). Given the dynamic nature of the field, many of these entries have been revised and updated, and a number of new entries have been commissioned, giving a more complete coverage of the domain of educational technology. New entries include: Computer-supported Design for Computer-aided Instruction, Computer-based Curriculum Development and Job Aids.
