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)
