Dave is the one of the best teachers that I have met. Humorous lecture styles ,and the rich content of the class are the excellent points. And, I think that the class will be better if more multimedia contents can be used. That is a modest proposal. Thank you, Pro. Dave, for the brilliant course you gave us.
David teacher's class is humor and it likes the kind of European and American people who bring their own sense of humor! His course is also very practical to meet the needs of our classmates! The only shortcomings of the individual is that the English level for me is low! whole English teaching is a little difficult for me！
