15 Describe something you like about operating experiments remotely- “They allowed me to understand concepts as they are applied.” “It is impressive to thing that such a small operation results in a change in a large system quite some distance away.” “It is interesting to be able to control something miles away with a computer.”

16 Describe something you like about operating experiments remotely- “Shows how the math relates to real- life problems.” “It was interesting to see different schools using the same heat exchanger.” “It did not take all day to complete.” “Our school does not have to buy it, keeps tuition low.” “Not limited to only what our school has.”

17 Describe some disadvantages of operating experiments remotely- “The experiments were sometimes interrupted by malfunction in the computer system.” “You don’t see the actual results of the input. It would be nice to see the system we are working with.” “Cannot see the experiment.”

18 Describe some disadvantages of operating experiments remotely- “Harder to understand because cannot see physical experiment.” “Not hands on, just collecting data.” “Can’t see the process, can’t see valves / tanks.”
