顶岗支教实习生实习学校一般为乡下学校,实验器材相对缺乏且实习教师实验水平有限。实习物理教师在利用牛顿管演示自由落体运动时,因不能很好控制牛顿管翻转速度、管内物体下落时间短且两物体比较容易相互接触,不利于学生对实验现象进行观察。现利用在牛顿管上增装隔断和磁性材料、在下落物体上增装小铁片的方法克服上述缺陷,更有利于学生对自由落体运动全过程进行观察。
Post teaching intern traineeship schools are generally rural schools, experimental equipment is relatively scarce and experimental teachers experimental level is limited. When using the Newton tube to demonstrate the free-fall movement, the internship physics teacher can not observe the experimental phenomenon because they can not control the turning speed of the Newton tube well, the object drop time is short and the two objects are easy to contact with each other. Is the use of Newton tube with partition and magnetic materials installed in the drop objects on the method of small iron overcome these shortcomings, more conducive to the students to observe the whole process of free-fall movement.
