刍议控制变量法在小学数学教学中的应用

The Application of Control Variable Method in Elementary School Mathematics Teaching

小学数学教学的部分内容,或显性或隐性呈现需要控制变量进行研究和学习的特点。对这一部分内容的学习,可以在显性的控制变量内容学习中,教给方法,整体建构;在隐性的控制变量内容学习中,渗透思想,价值提升。通过控制变量法可促进学生对学习的整体建构,使学生逐步掌握学习数学的应有思维方法。

The main characteristic of mathematic instruction in primary school can be concluded as using variable control in an explicit or implicit way for in-depth study.As for the explicit study of variable control,method teaching and overall structural thinking should be employed.Meanwhile,we can achieve a sound effect in implicit study of variable control by idea inspiration and value promotion.Due to such well-rounded training of overall structural thinking,students will gradually acquire the essential thinking method for mathematics study.
