高小算术第三册“分数除法”这部分教材是按分数除法的意义,分数除以整数,整数除以分数,分数除以分数,带分数除法,分数乘除、加除、减除混合运算和应用題的順序編排的。我們在备課时认真地研究了教材,认为分数除法是在学生已經理解并掌握了整数除法和分数乘法的基础上进行教学的,在保証完成教学任务的前提下,可以把新授的知識归类集中,調整教材的編排,以求貫彻教学改革的精神。于是决定把这部分教材改成三节;第一节讲分数除法的意义和分数除以分数的运算法則(分数除以整数、整数除以分数和带分数
This book is based on the meaning of fractional division, divided by the integer, integer divided by the fraction, divided by the fractional score, with fractional division, fractional addition, addition, subtraction, mixed operations and applications The order of the title arrangement. We carefully studied the lesson preparation materials, that fractional division is in the students already understand and master the integer division and fractional multiplication based on the teaching, to ensure completion of teaching tasks under the premise that the newly granted knowledge of Class concentration, adjust the textbook layout, in order to implement the spirit of teaching reform. Then decided to put this part of the text into three sections; the first section on the significance of fractional division and fractional algorithm divided by the score (divided by an integer, divided by the whole number of fractions and fractional
