So far I can think of five uses for computers in education:
Learning Objects: Big or small items, created by instructors or instructional technologists, that teach by knowledge transfer or interaction, including assessment.
Learning Tool: Learning is done by the student using technology creatively, including programming.
Organizer: Technology is used to organize information, including spreadsheets and databases.
Presentation Tool: Technology is used in the presentation of information, including presentations, animations and web sites.
Social Computing: Technology provides the mechanism and structure for communication, including e-mail, discussion boards, blogs and wikis.
Is that it? Is there another category I'm missing?
Documentation I've written that I'd prefer not to misplace
