凡事都有境界之分的,为人、为事、为学问均不例外。凭三尺讲台、一方空间的数学课堂,能否区分出境界的高下呢?能的,只不过划分的标准会见仁见智。笔者不揣浅陋,尝试做一番探讨。其一为“效率境界”。我们常常会用“扎实”“实在”“高效”等词来评判这类课堂。追求效率的数学课堂在我国有其历史渊源,1978年国家颁布的教学大纲明确提出要加强基础知识和基本能力的训练。从那时起,“双基”在中国教师的头脑 Everything has a realm of points, people, things, for learning are no exception. With three feet podium, one side of the math classroom space, can distinguish between the out of the realm of it? Yes, but the standard of division of opinion will be different. I do not guess humble, try to do something about it. One is “efficiency level”. We often judge such classes with the words “solid”, “real”, “efficient” and so on. The mathematics classroom in pursuit of efficiency has its historical origins in our country. In 1978, the syllabus promulgated by the State explicitly proposed to strengthen the training of basic knowledge and basic abilities. Since then, the “double base” teacher’s mind in China
