设计构想对于小学生来说,圆柱体积公式的推导、理解和掌握,均有一定难度。为攻克这一难点,我们准备基本上采用黎世法教授提出的“自学·启发·复习·作业·改错·小结”六因素单元教学法,设计这节课的教学程序,以取得良好的教学效益。使用课本通用五年制小学数学课本十册第19～20面。教学要求使学生理解和掌握圆柱体积的计算公式,并能运用公式 Design concept For pupils, the cylinder volume formula derivation, understanding and mastery, have a certain degree of difficulty. To overcome this difficulty, we plan to basically use the teaching method of “self-study, inspiration, review, assignment, error correction and summary” six-factor unit method proposed by Professor Li Shifa to design the teaching procedure of this lesson so as to achieve good teaching benefits. Use Textbooks General Five-Year Primary Mathematics Textbooks Volumes 19 ~ 20. Teaching requirements enable students to understand and master the formula for calculating the cylinder volume, and to use formulas
