The best math teacher:

UBC Math 316 (partial differential equation) teacher. 

He always starts a topic by telling a story;

Then clearly states the importance of this topic, i.e., why are we interested in this topic;

Then explores the topic so that students can have an idea what tools will be used;

Then mathematically explain it, with a solid conclusion in the end;

Further expansion of the topic;

SMILE ALL THE TIME!

He can apply the above principles (maybe) because this subject is highly reality-related. It is not that good if he can only do so in one or two classes; however, he does follow the above in almost all his class. Thus, even though he does not apply these rules in some classes, students can still positively take his class.

The worst math teacher:

This is totally imagined so that I cannot really tell a story or a background.

Directly go into the mathematical topic without explaining the interests;

Copy notes rather than explanation;

Strict exam grading process that students cannot explain things freely;

Take students' negative comments personally.
