因式分解是初中数学的重要内容,笔者根据2005年,2008年及2011年执教七年级数学的教学实践,对苏科版教材“因式分解”教学中有如下三点看法:整式乘法与因式分解间隔讲解;课时安排需要增加;适当补充分组分解法和十字相乘法。在实际教学中,面对新理念、新教材,我们要善于创新,勇于挑战,但许多传统的数学教学也不应抛弃,要扬长弃短,珍惜几十年来宝贵的数学教学经验,对其继承和发扬。
Factorization is an important part of junior high school mathematics. Based on the teaching practice of the seventh grade maths in 2005, 2008 and 2011, the author has the following three views on the teaching of Su Ke edition: “Factorization”: The integral multiplication And factoring interval to explain; class schedule needs to be increased; appropriate to add group decomposition and cross multiplication. In the actual teaching, in the face of the new ideas and new teaching materials, we should be good at innovation and brave challenges. However, many traditional mathematics teaching should not be abandoned. We should abandon the short and cherish the precious teaching experience in mathematics for decades, And carry forward.
