Key vocabulary to listen for: what is on your ??? list?

In class, Dan noted to me that it would be helpful to have a discussion/definition around some of the terms that get tossed a lot "around here" (and elsewhere in engineering education).  :-)  Some of those terms include:

• scaffolding
• epistemology (as noun, adjective)
• pedagogy (as noun, adjective, verb?)
• 
  

What are other terms you hear tossed around that you really wish someone would define, situate, or outline for you?
