人的双手的动作对发展智力的作用,人们早已有所觉察。有人估计,人的双手能做出几十亿种动作,而手的动作又是跟思维活动直接联系的,对发展思维起着积极的作用。用手工作是激发智力才能,学习物理知识的一种强有力的刺激物,下面列举数例略加说明。 1.在讲授“物体间力的作用是相互的”这一知识时,我让全体学生尽力鼓掌,然后,由学生分别把自己的左右手感受及时间性问题(同时)表达出来,使学生真正体会到“孤掌难鸣”的物理含义。 2.在讲解课本对摩擦粗浅的解释即“当一个物体在另一个物体表面滑动时,互
The role of human hands in the development of intelligence has long been known. Some people estimate that human hands can make billions of movements, and the movements of hands are directly linked with thinking activities, which play a positive role in the development of thinking. Working by hand is a powerful stimulant that stimulates intelligence and learns physics knowledge. A few examples are shown below. 1. When teaching “the effect of forces between bodies is mutual”, I let all students try their best to applause. Then, the students separately express their feelings of right and left hands and time problems (simultaneously), so that students can truly understand To the physical meaning of “single palm difficult”. 2. In the explanation of textbooks, the explanation for friction is that when an object slides on the surface of another object,
