现阶段,物理课程已成为学生面临的一道“坎”。就像学生在学习有关“平均速度”的知识时,始终会有这样的问题:分不清动态物体在不同路段行驶的平均速度v,致使学生根本无法获取准确的速率变化,对这一内容也就不能很好地理解。针对这一现象,教师应积极实施实践性体验教学模式,安排学生真正地去体验“平均速度”的实验过程,进而实现初中物理课程的教学目标。很多时候,老师在课上讲“平均速度”的时候,总是简单地拿个粉笔,在黑板上或桌上做直线匀速运动。其实这个方法是最简
At this stage, the physical curriculum has become a “face” facing students. Just as students learn about “average speed,” there is always the question of failing to tell the average speed v of moving objects across different road segments, leaving students with no way of getting accurate rate changes The content can not be well understood. In response to this phenomenon, teachers should actively implement practical experience teaching mode, arrange the students to really experience the experimental process of “average speed”, and then realize the teaching goal of junior high school physics curriculum. Very often, when teachers are talking about “average speed” in class, they always simply take a piece of chalk and make a straight, uniform motion on a blackboard or table. In fact, this method is the most simple
