一、教材简析本教学内容是苏教版七年级(上)第二章第六节内容,《有理数的乘方》是综合了有理数的四则运算的全部知识,要求学生要有牢固的四则运算基础,并且关系到后面有理数的混合运算、科学计数法和开方的基础,有着重要的过渡作用。二、设计理念要能够让学生理解乘方的实际意义的基础上熟练准确地进行乘方运算,引导学生从数学的角度去思考生活中的事件,增强学生解决实际问题的能力,训练学生形成类比、归
First, the textbook analysis This teaching content is the seventh edition of the Sujiao Version (on) Chapter II, Section VI, “rational number of power” is a combination of all the knowledge of the four operations of rational numbers require students to have a solid four arithmetic Basis, and related to the back of the rational number of mixed computing, scientific counting and prescribing basis, has an important transitional role. Second, the design concept To enable students to understand the practical significance of the Empire on the basis of skilled and accurate power operation, to guide students from a mathematical point of view to reflect on life events, enhance students ability to solve practical problems, training students to form analogies , Go
