What are "Web Laboratories"?
REAL Lab experimentsfor engineering educationoffered via the WEB
Enhance student learning opportunitiesDistribute equipment use over time and place….
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)
