He is a facilitator who has his own teaching method. My teammates and I have benefitted from his facilitation, and the whole team achieved a very good result. I feel very comfortable in his class, which makes me study more effectively than a sleepy class. He played some funny videos to release our tiredness.  The most impressive thing is that: not only does he teach us the academic knowledge but also together with how we should behave in our daily life.  With these, we did make a difference.
