摘要
机车牵引力的本质较为复杂,有许多不同的观点.在课堂教学中,常对牵引力加以简单处理以便解题,但易引发学生思维矛盾.本文首先通过两道习题,阐述由于对牵引力的处理方法不同而引起学生的疑问;再通过整理相关的理论观点,提出一个适合向高中生解释的思路,最后紧扣核心素养要求,从教学和命题两个方面探讨在高中阶段处理牵引力相关问题的思考.
The essence of locomotive traction force is complex and there are many different perspectives.In classroom teaching,simple handling of traction is often used to facilitate problem-solving,but it can easily lead to students'thinking conflicts.This article first elaborates on the questions raised by students due to different methods of handling traction force through two exercises;By organizing relevant theoretical viewpoints,propose a suitable approach to explain to high school students,and finally focus on the core competency requirements,explore the thinking of handling traction related issues in high school from both teaching and proposition perspectives.
