The Domain of Development Development is the process of translating the design specifications into physical form. It includes hardware, software, visual and auditory materials, as well as the programs or packages which integrate the various parts. The sub-categories of the development domain reflect chronological changes in technology, with new overlapping but not replacing old. Print Technologies Print and visual materials, including books, photographs and graphics involve the most basic ways of producing and delivering instructional materials. They also provide the foundation for both the development and utilization of other instructional technologies.
Text displayed by a computer is an example of the use of computer-based technology for production.
When that text is printed in hard copy to be used for instruction, it is an example of delivery in a print technology. Development of text materials and visual materials relies upon theories related to visual perception, reading and human information processing as well as theories of learning. Audiovisual Technologies Audiovisual instruction is most obviously characterized by the use of hardware in the teaching process, that is, using mechanical or electronic machines to present auditory and visual messages. There is an increasing overlap of AV Technologies with Computer-based Technologies. For example, a video is an audiovisual technology.
