一、背景和教学任务“运动的图象描述”是上科版新教材第一章变速直线运动的第二节内容,要求学生学会运用物理模型和数学方法(图象、公式).思维要求较高,不但要求让学生理解、掌握以物理图象为载体研究物理问题的一些基本思路和方法,并且要在教学过程中激发学生的学习兴趣,让学生愉快地学、聪明地学.二、教学目标1.知识和技能(1)理解位移—时间图象及其物理意义;
First, the background and teaching task “image description of the movement” is the second section of the first chapter of the new textbook of the Shanghai Institute of Speed-changing linear motion. Students are required to learn to use physical models and mathematical methods (images, formulas). Gao, not only requires students to understand and master some basic ideas and methods for studying physical problems using physical images as a vehicle, but also to stimulate students’ interest in learning in the teaching process so that students can learn happily and intelligently. Second, teaching objectives 1 Knowledge and Skills (1) Understanding displacement-time images and their physical meaning;
