《转陀螺》是苏教版《科学》四年级下册的一课,教学目标是探究陀螺转动现象及其规律。怎样在课堂上让学生真正投入到自主研究中去,这是我一直思考的问题。是否可以学习路培琦老师研究“摆”的方法?他在课上把学习研究主题定为“设计一个摆,让摆15秒摆动10次。”我也可尝试把研究主题定为“让陀螺转25秒”。
Gyro Gyro is a lesson from the fourth edition of Science in the Sujiao edition. The teaching goal is to explore the gyro gyration and its laws. How to make students really devote themselves to independent research in the classroom is a question that I always think about. Can he study the method of “pendulum” by Lu Pei-qi? In his class, he set the theme of his study as “designing a pendulum and letting it swing 10 times in 15 seconds.” I can also try to set the theme of my study as “ Turn 25 seconds. ”
