Teaching with Labs is Fun…
But hard… why?
 Students have different learning styles
 Students learn at different rates
 Students have different levels of interest
 Students don’t read
 Students main problem solving method is
“trial & error” and Google
 Lab-based courses are harder to teach:
 Students have questions at the same time
 You are a hostage to environment
 Not all problems are related to content
3
The Process
