变式教学,主要是指在保持事物本质特征不变的情况下,通过从不同角度、方位、背景等方面,有目的、有针对性地对数学概念、公式、定理、习题等进行变换,从而引导学生从“变”的现象中挖掘和把握“不变”的内在规律和本质属性,培养学生灵活多变的思维能力。在高中数学教学中,教师耍立足教学实际需要,优选有效策略,灵活巧妙地开展变式教学,从而发散学生思维,提高教学效果,促进学生的有效发展。对此,笔者结合教学实践,就变式教学在高中数学课堂
Variant teaching mainly refers to changing the mathematical concepts, formulas, theorems, exercises and so on purposefully and pertinently from different angles, orientations, backgrounds, etc. under the condition of keeping the essential characteristics of things unchanged Guide students from the “change ” phenomenon to tap and grasp “constant ” inherent laws and essential attributes, to develop students flexible thinking ability. In high school mathematics teaching, teachers should base on the actual needs of teaching, optimize the effective strategies, flexibly and skillfully carry out the teaching of variation, so as to diffuse the students’ thinking, improve the teaching effect and promote the effective development of the students. In this regard, the author combined with the teaching practice, the variant teaching in high school mathematics classroom
