笔者认为,在日常教学中引导学生用废弃的物品制作教具、学具,既可提高学生学习物理的兴趣,又可培养学生的创新精神和实验能力。下面,笔者以废旧医用输液管制作“流体压强与流速的关系实验器”为例,谈谈认识。 I believe that in daily teaching to guide students to use the discarded items of teaching aids, learning tools, both to improve students ’interest in learning physics, but also to cultivate students’ innovative spirit and experimental ability. The following, the author of medical waste tube production “fluid pressure and the relationship between the flow rate experiment ” as an example, to talk about understanding.
