在《运动快慢的描述——速度》的教学过程中,依据高中物理课程标准,结合学生的实际情况,对教学内容进行了适度的增加、删减、置换、加工。移“坐标与坐标的变化量”至第二节中的“直线运动的位置与位移”后讲解、增加匀速直线运动和变速直线运动的概念、补充平均速率、增加位移—时间图像。
In the course of “Description of Speed - Speed”, according to the standard of high school physics curriculum, combined with the actual situation of students, the content of teaching is added, deleted, replaced and processed moderately. Move “Coordinates and Coordinate Changes ” to “Position and Displacement of Linear Motion” in Section 2, explaining the concept of adding uniform linear motion and variable linear motion, adding the average velocity, and adding the displacement-time image .
