《高等数学》直观性教学探索——以“微元法”教学为例

On Visual Method of Teaching in Higher Mathematics

从定积分的定义出发,以学生的经验为基础,将"微元法"在几何中求曲线长度、面积及体积归结为"积点成线、积线成面、积面成体",通过语言、图像直观降低了学生学习该内容的难度,达到了直观性教学目的。

From the definition of definitc lntegral and on the basis of student＇s experience, we summarized the micro element method which finds the length of curve, area and volume in geometry as ＂accumulate dots become line, accumulate line become area and accumulate area become volume.＂. The teaching method, by language and visual pictures, reduced the difficulty for students to learn the course and achieved the goal of visual teaching.
