Again, it seems like every course regardless of subject matter, communication is always important. From this unit, I particular learned that, depending on your audience, how you communicate is an area that consistantly needs improvement. The S2S, S2I, I2S, G2G, etc...are some great examples provided to where addressing a certain audience matters on how one shares or critiques a subject.
I never conisder "scaffolding" a mean for building on your skill set, but I will definitely focus on this method when developing my syllabus.
