摘要
"单位"教学在整个物理教学中必须占有举足轻重的地位。因为如果只是数字而没有相应的物理量单位,则该数据就只能是一串阿拉伯数字,没有任何的物理意义。同时单位教学还可以在物理教学中起到承上启下、画龙点睛的作用。
The teaching of units should play an important role in physics teaching. If numbers go without corresponding physical units,they have no physical meanings. At the same time,the teaching of units is a connection link in physical teaching. It also adds add the finishing touch to the physical teaching.
