Vision & Plans Remote Expanded learning opportunities Engineering
Asynchronous Laboratories University Partners Industry Partners
30
Vision & Plans -- Students will have access to on-line labs with a
variety of experimental systems in mechanical and chemical engineering
31
Vision & Plans -- Students will be able to easily design and
conduct experiments from home, dorm, computer lab or office
32
Vision & Plans -- Students will be able to compare
local lab experimental results with on-line lab results
33
Vision & Plans -- Faculty will have materials
to implement remote laboratory experiments in their own institutions
34
Vision & Plans -- Faculty will have more diverse laboratory offerings
35
Vision & Plans -- Faculty will be able to easily use on-line labs
in classroom demonstrations
