本世纪五十年代,中国小学数学教学的“三算结合”脱颖而出,七十年代风糜全国,以后由于种种原因,一度低落,八十年代初重新恢复试验,很快推行到全国各地。1980的起,部分学校在“三算结合”实验的基础上,强化珠算图像,进行珠算式心算教学实验,取得了令人瞩目的成效。 所谓珠算式心算,简单地说,就是在头脑里打算盘。由于一个人珠算的进步,算盘可以达到内化的程度,即将数变成算珠浮现在脑中进行计算。一个好的 In the 1950s, the “three counties combination” of mathematics teaching in primary schools in China came to the fore. In the 1970s, it was all over the country. For various reasons, it was once low and the tests were resumed in the early 1980s. It was soon introduced throughout the country. Since 1980, on the basis of the experiment of “three calculations and combination”, some schools have strengthened the abacus image and experimented on the abacus teaching of mind abacus, and achieved remarkable results. The so-called abacus mental arithmetic, simply put, that is, in the mind intends to disk. Abacus can reach the level of internalization due to the progress of a man's abacus, ie counting the number of abacus into the brain. A good one
