人教版新课标高中物理必修1速度变化快慢的描述─加速度说课稿2篇
本来比较速度变化的快慢也有两种方法：一种是比较相同时间内速度变化量的大小；另一种是比较发生相同的速度变化所需要的时间长短。但教材是将比较质点位置移动快慢的思想直接迁移过来，通过实例分析，使学生明白不同运动物体的速度变化快慢不同，表现在速度的变化与发生这个变化所用时间的比值不同，从而引入加速度的定义方法a=△v/△t。加速度表示速度的变化快慢，包括速度增加的快慢和减小的快慢，不能误认为只要有加速度的运动速度就一定是增加的。广义地讲，加速度不仅可以描述速度大小的变化快慢，而且也可以描述速度方向变化的快慢，本节教材只限定在直线运动的情景中讨论。加速度的矢量性是一个难点，教材是以与速度方向相同或是相反来表述加速度的矢量性的。如果以初速度方向为正方向，那么加速度就有正负之分，加速度的正负表示加速度的方向，不表示加速度的大小。

人教版新课标小学数学一年级上册比长短、高矮 说课稿
第一步骤是：游戏引入课一开始,我先出示2支铅笔,用手捏住一端,这样让学生产生一个错觉,再放开手,让学生重新进行判断,从而得出比较２个物体的长短要一端对齐的方法。从游戏引入，能很好地激发学生的好奇心，同时又利用学生的已有经验，由学生轻松得出比较长短的方法，为下面的活动做好了知识铺垫，既有趣，又有效。第二步骤是：比长短活动有了刚才比的方法的铺垫，再让学生找找自己想比长短的东西，然后进行自由比较。在这里，主要要放手让学生发挥自主性，但由于学生年龄太小，这里教师要加强引导，所以在让学生自己比之前，我让学生先说说想到了可以比什么。在学生自己动手的时候，我也深入其中，加强指导。在反馈时，还让学生演示一下，一方面要让学生体验到交流的成就感，另一方面也是培养其他学生认真倾听的习惯。
