卖艺 + 小丑+ 演员 = 老师

变了,世界变了,晴朗的天气,也会下雨。宽阔的道路,也会堵车。
变了,世界真的变了。
变了,老师也变了。

有时自己在想,曾几何时,我会想当起老师呢?
想不起了,只记得 1997 年, 我第一次。

那时的老师非常伟大,得到学生的尊敬,爱戴。每一天,每一堂课,都有一些有心向学的学生,向我问学
慢慢的,慢慢的,学生变了,即食文化来了,
功课不做了,书也不读 了,考试来了,如何?
不难,老师有 tips,可是,tips 准吗?
不怕,老师有 bocor,可是,有bocor 也不会,
放心,老师有 answer,背了它,明天拿 A,后天妈妈奖励,大后天庆祝。
下个星期跟老师说 :老师,你很神!

没有tips 的老师呢 ?糟了,没人来了,课室空了,坐小车了,CLK…..
聪明的学生,你在那里 ?

变了,真的变了
现在的老师,需要十八般武艺,会说,会讲,会笑,会喊,会叫,会教,会英文,会国文,会华语,会粤语,会科学,会数学,会物理,会音乐,会科技,会说笑,会给tip,最后,会做小丑

做小丑真的不简单,每一天的舞台表演,都不容易,真的,台上一分钟,台下十年功
每一场,小丑 = 老师们都要取悦观众,每一场,都要做到100,每一场,都要观众们一笑而归。
小丑,老师的代名词
那,如有老师不想当小丑,怎办 ?
当演员吧 !

现在的老师,不需要学问,只要会演,“粉屎”一大堆
演的好,没有学问,没有文凭,没有经验,教错,乱教,是问题吗?
一笑而之,最重要,学生多,“粉屎” 多,上课爽,开心

变了,世界变了

学生们,聪明的学生们,醒吧!
未来的世界是你们的,醒吧!
路是没有捷径的,读书也没有捷径的,醒吧!

我是老师,我不是卖艺的,也不是小丑,更加不会演

我只是位老师
真实的老师

Section A
1) Water wave interference, ripple tank
2) Lens, 1/u + 1/v = 1/f

Section B
3) Relationship between the pressure and depth
4) Diameter of the wire affecting resistance

Hypothesis : For a fixed length of a conducting wire; the thicker the wire, the smaller the resistance
Manipulated variable : Thickness of wire
Responding variable : Resistance
