摘要
理论教学是数学教学基本的、重要的环节，教学方法应利于传授知识、启发思维、促进学生思维能力、创造能力和应用能力等综合素质的发展。结合定积分的教学实践，探讨数学课理论教学的原则和方法。
The teaching of theories is the basic and important links in the course of mathematics. Jeaching metheds must be favourable to passing on knowledge, inspiring thought, promoting the development of student's thinking ability, creative ability, applieation ability and other abilities. This paper will make an inquiry into the teaching principles and methods of the theories in the course of mathematics in the light of the teaching practice of Riemann Integral.
