一、注重学生情感,尊重学生自信心为克服学生自卑心理,不敢大胆尝试的恐惧心理,教师通过穿插数学史中伟人的历程,告诉他们即使是数学伟人也会有错误发生。教师可以尝试让学生当一个研究者,做一些类似于数学研究之事。如在学完函数的单调性后,让学生讨论两个都增的函数的复合函数的单调性,两个都减的函数的复合函数的单调 First, focus on student emotions, respect for student self-confidence To overcome the psychological inferiority of students, not afraid to try the fear, the teacher by interspersed with the history of mathematics in the history of great people to tell them that even the great math would have a mistake. Teachers can try to be students as a researcher and do something resembling mathematical research. For example, after learning the monotonicity of a function, let the student discuss the monotonicity of the composite function of both increasing functions and the monotony of the composite function of both decreasing functions
