教学评价离不开定量分析。先人从《孟子·梁惠王上》的一则故事中析出“五十步笑百步”这个贬义成语,用来比喻程度虽然不同、但本质却一样的人与事。据此,五十步是没有资格笑百步的。但兵法上还有敌进我退、以退为进的韬略,倘若将必要的战略撤退规定为五十步,那么,“五十步笑百步”就未尝不可,而后退百步便有“逃跑主义”之嫌,与五十步就有质的不同了。可见定量分析的关键,在于对事物的质的量和量的量作出科学的规定。对于小学教学评价来说,要使定量分析 Teaching evaluation is inseparable from quantitative analysis. The ancestors from the “King of Mencius Liang Hui,” a story of “five steps and laugh hundred steps,” a derogatory idiom, used to metaphor though different, but essentially the same people and things. Accordingly, fifty steps are not qualified to laugh at hundred paces. However, if the strategic retreat is stipulated as fifty steps, then the “tactical retreat of the fifty steps” is not a bad idea, but there are “backward hundred paces”. The suspicion of “escapedism” is qualitatively different from that of the fifty steps. It can be seen that the key to quantitative analysis is to make scientific regulations on the quantity and quantity of things. For the assessment of primary education, quantitative analysis is required
