一、学情分析本节复习课,学生对多项式乘以多项式可转化为单项式乘以多项式,再转化为单项式乘法等算理重视不够,在运算和思想方法的运用上欠缺较多,失误不断。虽经过复习后一般能掌握,但在应用解解题时普遍缺少应用意识,如通过因式分解后对分式约分或通过因式分解后用整体思想去解题等。二、设计思想1.数学课程标准(2011年版)对该知识的目标要求能用提公因式法、公式法(直接利用公式不得超过两次)进行因
First, the academic situation analysis This section review class, students multiply polynomials can be converted into polynomials multiplicative polynomials, and then converted to monistic multiplication and other arithmetic attention is not enough, in the operation and thinking of the lack of use, mistakes continue. Although generally can be mastered after review, but the application of the general lack of solution to the problem of application of consciousness, such as through factoring after the fractional or by factoring after decomposition with the overall idea to solve the problem. Second, the design idea 1. Mathematical curriculum standards (2011 Edition) The goal of the knowledge can be used to mention the public factor method, the formula method (direct use of the formula can not be more than twice) for
