单摆、滑动摩擦力、动能和重力势能、电阻是人教版初中物理中典型的“多变量”问题,初中学生在遇到此类较为抽象的物理概念和规律时,常会出现变量记忆混淆,无法准确区分真伪变量,增加了学生学习的难度,若能将高中物理的相关公式引入到初中物理的教学中,就能把抽象、复杂的问题直观化、简单化,可以降低学习难度,拓宽学生视野,增加教学的有效性。
Single pendulum, sliding friction, kinetic energy and gravitational potential energy, resistance is a typical “multivariable” problem in the Junior High School Physics of PEP. When junior high school students encounter such abstract concepts and laws, they often have variable memory Confusion, can not accurately distinguish between true and false variables, increasing the difficulty of student learning, if the high school physics can be related to the introduction of the physics teaching, you can abstract, complex problems can be visualized and simplified, can reduce the learning difficulty , Broaden students’ horizons and increase the effectiveness of teaching.
