《改进小水钟》教学实录与点评

Teaching Record and Comments on “Improving the Little Water Clock”

《改进小水钟》一课让学生制作一个简单的一级泄水型和受水型水钟,引导他们对自己制作的水钟进行使用、测试,最终聚焦水流速度不稳定的问题。学生在不断挑战的过程中,探究能力得以提升,科学精神得以养成,动手经验得以积累,这些都为他们未来关于技术与工程领域的进一步学习形成正迁移。

In the lesson of"improving the little water clock",students are asked to make a simple firstclass water clock,which can discharge water and receive water.They are guided to use and test their own water clock,and finally focus on the problem of unstable water flow speed.In the process of continuous challenges,students’inquiry ability can be improved,scientific spirit can be cultivated,and hands-on experience can be accumulated,which form a positive transfer for their further study in the field of technology and engineering in the future.
