数学学科是以严密而著称的,那么对于学习数学的人来说,学习时间长了,逻辑性和严密性会逐渐内化为人的性格.的确,数学学科的这一特点在教材中的各种表述中表现得尤为突出,诸如定义、命题、性质、定理等都有讲究,增一字少一字都不完美.2011版课标颁布以来,全国六、七种之多的多元化数学教材版本都对应前六年的实验版重新做了修订和完善,那么这些新教材是否遵循“数学以严密而著称”的理念进行表述了呢?下面以“等式的基本性质”为例来看一下几种典型教材的表述.北师版:
Mathematical discipline is strictly known, so for those who learn mathematics, learning time is long, logic and rigor will gradually internalize into a person’s character.Many of the characteristics of mathematics in the textbook of the various The expression is particularly prominent, such as the definition, proposition, nature, theorem and so on are stressful, less word by word is not perfect .2011 version of the standard since the promulgation of the country as many as six, seven kinds of diversified math textbooks All correspond to the experimental version of the first six years to re-amend and improve, then whether these new textbooks follow the “mathematically rigorous and well-known” concept to express it? Here to “the basic nature of the equation ” as an example Take a look at the presentation of several typical textbooks.
