【摘要】 微课以微视频为载体,易于让学生聚焦在教学的重难点上,方便学生的自主学习。高等数学中的旋转体体积的计算是利用微元法解决的一类经典问题,也是学习的难点。本文首先分析了微课的特点,介绍了旋转体体积的教学背景,继而详细探讨了旋转体积的微课设计。更多还原

【Abstract】 Micro-lecture presents a single knowledge point. Micro video is the important part of Micro-lecture.Students are easy to focus on the key point or difficulty point in the micro-lecture. facilitate students’ Autonomous learning. Calculate the volume of solid of revolution is a kind of classical problem,the common method is the element method,but it is difficult to learn. This paper first analyzes the characteristics of the micro lecture,introduces the teaching background of the volume of the solid of revolution,then discusses the design of the micro lecture.更多还原
