Vision & Plans

Expanded learning opportunities

RemoteEngineering

AsynchronousLaboratories

University Partners Industry Partners

Page 30: Improving Laboratories with Internet Controlled Equipment and Internet Student Support Jim Henry, Ph.D., P.E. Charles Knight, Ph.D., P.E. College of Engineering.

Vision & Plans

-- Students will have access

to on-line labs with a

variety of experimental systems

in mechanical and

chemical engineering

Page 31: Improving Laboratories with Internet Controlled Equipment and Internet Student Support Jim Henry, Ph.D., P.E. Charles Knight, Ph.D., P.E. College of Engineering.

Vision & Plans

to easily design and

conduct experiments

from home, dorm, computer lab

or office

Page 32: Improving Laboratories with Internet Controlled Equipment and Internet Student Support Jim Henry, Ph.D., P.E. Charles Knight, Ph.D., P.E. College of Engineering.

Vision & Plans

-- Students will be able to compare

local lab experimental results

with on-line lab results

Page 33: Improving Laboratories with Internet Controlled Equipment and Internet Student Support Jim Henry, Ph.D., P.E. Charles Knight, Ph.D., P.E. College of Engineering.

Vision & Plans

-- Faculty will have materials

to implement remote laboratory

experiments in their own institutions

Page 34: Improving Laboratories with Internet Controlled Equipment and Internet Student Support Jim Henry, Ph.D., P.E. Charles Knight, Ph.D., P.E. College of Engineering.

Vision & Plans

-- Faculty will have

more diverse laboratory offerings

Page 35: Improving Laboratories with Internet Controlled Equipment and Internet Student Support Jim Henry, Ph.D., P.E. Charles Knight, Ph.D., P.E. College of Engineering.

Vision & Plans

-- Faculty will be able

to easily use on-line labs

in classroom demonstrations
