初中数学高效课堂的有力抓手——变式训练

A Powerful Hand for Junior High School Mathematics Efficient Classroom-Variant Training

在应试教育的束缚下,题海战术仍是大部分初中数学教师用于提升学生解决问题能力的主要手段,该训练形式虽然在学生成绩提升方面有一些作用,但是对学生思维能力的独立性和发散性却没有实质性的帮助。为此,本文将对初中数学高效课堂的有力抓手——变式训练进行深入探究,重点阐述如何抓准问题变化方向,并运用变式训练增强学生存储和理解数学知识的能力。

Under the constraints of test-oriented education, the question sea tactics are still the main means used by most junior high school math teachers to improve students’ problem-solving ability. Although this training form has some effects in improving students’ performance, it has an effect on the independence and independence of students’ thinking ability divergence does not help substantively. To this end, this article will conduct an in-depth exploration of the powerful grasp of junior high school mathematics efficient classroom-variant training, focusing on how to grasp the direction of the problem change,and use variant training to enhance students’ ability to store and understand mathematical knowledge.
