变式教学是初中数学课堂的中最为常见的教学行为,特别是有丰富经验的教师,更会把变式训练变得如鱼得水、变化自如.本文,笔者结合自己在教学环节中变式教学的实践和研究,就变式教学的合理应用谈几点拙见.一、原则性1.目标明确性原则在教学过程中,我们的变式必须要有明确的目的性,变式针对的对象要明确,一定要在教学目标和课程目标的基础之上来变式,并且能通过变式满足学生对原有知识和技能的巩固和提升.比如学生在新授课中学习全等三角性的判定以后,我们
Variant teaching is the most common teaching behavior in junior high school mathematics classroom, especially the experienced teachers, it will make the variant training become a duck with water and change freely.This article, the author combined his teaching in the practice of variant teaching And research on the rational application of variant teaching a few humble opinion I. Principle 1. The principle of the target clarity In the teaching process, we must have a clear purpose of the variant, the target of the variant should be clear, Must be based on the teaching objectives and curriculum objectives to change, and can meet the students through the transformation of the original knowledge and skills to consolidate and enhance.For example, students in the new lectures to determine the determination of congruent triangle, we
