极限既是整个高等数学的基础,也是学生在学习高等数学中接触的第一个和初高中掌握的概念形式不同的知识点。如果极限的概念和应用掌握不好,一方面对于后续的导数、积分等概念难以理解,还极易产生厌学的情绪。本文根据极限部分知识特点,针对极限概念引入及极限求解等方面给出了相关的教学改进建议,以达到引起学生兴趣,便于学生理解和应用的目的。 The limit is not only the basis of the whole higher mathematics, but also the different points of knowledge that the students contact in their study of advanced mathematics. If the limits of the concept and application of poorly grasp, on the one hand for the follow-up derivatives, integral concepts difficult to understand, but also easy to produce tired of emotions. Based on the knowledge of the limit part, this paper gives some advice on teaching improvement in view of the introduction of limit concept and the ultimate solution so as to achieve the purpose of arousing students’ interest and making it easier for students to understand and apply.
