有一种观点认为:不管白猫黑猫,抓住老鼠就是好猫。我说,这种观点是不完整的,关键还要看怎么抓?是花了很大代价很大力气来抓,抓住了或者未抓住;还是花了较小代价较小力气来抓,抓住了或者未抓住。无论你付出了多少,未抓住,纯粹就是无效劳动;抓住了,还要看看效益的高低。这必须是要考虑的。我认为“有效教学”的目的就是要教师成为一个“轻松高效的猫”。 There is a view that regardless of white cats and black cats, catching mice is a good cat. I said that this view is incomplete, the key depends on how to grasp? It took a great deal of great efforts to grasp, or not caught; Or spend less effort to grasp the smaller, Caught or not caught. No matter how much you pay, did not catch, is simply invalid work; seize, but also take a look at the level of effectiveness. This must be considered. I think the purpose of “effective teaching” is to make teachers become “easy and efficient cats.”
