Discussions questions are a good starting point, however more needed to be developed to apply the ac/dc concept to the 21st century.

Opportunities for Deeper Learning: Limited (1)

More guidance and opportunities for deeper learning are needed. Before this class, I showed a video from the History Channel related to the heated debate of ac or dc.
