He can be very condescending, he's very good at teaching though
His greatest flaw is his refusal to challenge either his students or himself. It's like he moves and speaks in a different (slower) rhythm from all of us. However, I do believe he's very sharp.
it IS hard to stay awake with his same day in and day out teachings.
the only problem with mr. schaffner's classes is struggling to stay awake
Mr. Schaffner is a very nice teacher. He keeps his classes interested in what they are learning.
