Function of Counter-Examples Idea in Mathematical Analysis Teaching
Zhiyong Wang · Journal of Henan Institute of Education · 2012
By two counter-examples of the relationship between unbounded function and conclusion that the function goes to infinity and the fact that the mean value theorem only works in the range of real number,it is stated that counter-examples idea can make students understand conceptions and theorems better,and foster the preciseness of students' thinking,so the teaching effect can be increased.
