《中小学数学》(小学版)2011年第12期《这样的数该怎么读》一文,初读这篇文章觉得作者是一个善于思考的人,他能抓住教学实践中的小问题——“400000000改写成以‘万’为单位的数40000万后该怎么读?是‘四万万’还是‘四亿”’这一问题去反思和研究,确有独到之处。然而,当我细读几遍想真正抓住这篇文章的精髓时,却发现文中的一些见解并非有代表性,特别是文中对“四万万”的读法提出异议时,那些反驳的观点和例证没有足够的说服力。我觉得要想推翻一个观点,所有反驳的理由和例证必须没有一点疏漏,真正做到无懈可击。
“Primary and secondary mathematics” (Primary Edition) 2011 12 “how to read this number,” a text, first reading this article that the author is a good thinking person, he can grasp the teaching of small problems - “400000000 rewritten into thousands of units as the number of 400000000 how to read? Is the ’four hundred million’ or ’four hundred million’? This question to reflect on and research, there are indeed unique. However, when I read through several times to really grasp the essence of this essay, I found that some of the opinions in the essay were not representative. In particular, when I challenged the reading of ”40 million" in the article, The views and illustrations are not convincing enough. I think that if we want to overthrow a point of view, all the refuted reasons and examples must not be overstated and we are truly invincible.
