一、教学内容北师大版七年级数学下册P22—P24二、教学设想这一节课的教学内容是在学生已经学习了“同底数幂的乘法”、“幂的乘方”、“积的乘方”的基础上进一步探究幂的有关计算,体会幂的意义。在学生已有的学习经验的基础上,本节课的学习知识相对来说难度不是很大,学生容易理解接受;但是教材在例1的后面,给出了想一想和猜一猜,让学生通过探究归 First, the teaching content Beijing Normal University version of the seventh grade mathematics books P22-P24 Second, the teaching ideas The lesson content of the teaching is that students have already learned “multiplication ”,“ Product of the power of ”based on further exploration of the power of the calculation, the power to understand the meaning. On the basis of the students’ existing learning experience, the learning knowledge of this lesson is relatively not too difficult for students to understand and accept easily. However, the teaching materials are given in the back of Example 1 to think and guess Students go through inquiry
