勇于探究是科学精神的重要组成部分,利用典型任务范式有利于学生探究能力的培养,本文以浙教版科学九年级第三章《机械能》为例,让学生在完成机械能经典碰撞实验任务的过程中,体会转换法、控制变量法、类比法等探究方法;在体会能量转化的过程中,联系生活实际思考如何设计汽车的刹车装置、尝试解决科学工程问题. The courage to explore is an important part of the scientific spirit, the use of a typical task paradigm is conducive to the development of students’ inquiry ability. In this paper, the third chapter of the ninth edition of Science in Zhejiang Science Edition “mechanical energy” as an example, so that students in the process of completing classical mechanical energy collision experiments In the process of energy conversion, think about how to design the brakes of a car in real life and try to solve the problem of scientific engineering.
