Abstract:
Segmented function is a difficult point in function teaching, but if teachers
are good at infiltrating segmented function into function teaching, they can not only
make students have a deeper understanding of segmented function, but also broaden
students’ understanding of the concept of function and the monotony, parity and
periodicity of function.
分段函数在函数教学中是个难点,但如果教师善于将分段函数渗透在
函数教学中,不仅能使学生对分段函数有更深的理解,同时也能拓宽学生对函
数概念以及函数的单调性、奇偶性、周期性的认识。
