What are "Web Laboratories"?
Issues and challenges Technical UNATTENDED
OPERATION -- REFRIGERATOR AT HOME Pedagogy IM as
TA Sequenced instructions Interactions with a
faculty one reason students go to university
Pro of tele eduction parallel
experimentation -- same here as there, compare
not interacting with people -- ironically,
closer interaction Psychomotor skills -- typing
and mouse (some people are performance
challenged in various ways. so use voice or eye
movement. not all students have to do
everything)
