Variability, to enhance training variant can put the the the teachers and the the students out from the "title sea". For example if you speak at the concept, theorem,and the example, you can seize the opportunity to make a variant model and select some typical exercise, then let the the students discuss a variety of variants, and guide the the students to explore and study variant treatment methods. 2 useing the “suspect” to have fun.
