在“机械能守恒定律”的课堂实验教学中,教师采用自制教具巧妙演示实验的渐变过程,给学生提供直观的实验现象,实验由浅入深、循序渐进,遵循学生的认知规律,实验采用控制变量法使学生掌握研究物理的一般方法,重点培养学生的观察能力、思维能力、逻辑推理能力等物理素养。
In the classroom experiment teaching of “law of conservation of mechanical energy”, teachers use self-made teaching aids to demonstrate experimentally the gradual change process and provide students with intuitive experimental phenomena. The experiment goes from the shallower to the deeper, step by step, follow the students’ cognitive rules, and the experiment adopts the control The variable method allows students to master the general methods of research physics, focusing on cultivating students’ physical skills such as observation ability, thinking ability and logical reasoning ability.
