Advantages for the Instructor:
"...the discussion we had in class helped me to
understand inverses more so than if I was just to read the book. When
you picked on me to explain a question to another student [it] helped
me to understand because I had to explain it verbally instead of just
saying 'yes, I
understand'".
"..Dr. Barzilai, I am so excited because I am finally
grasping this material..."
