数学教育的首要问题,是教学内容本身的科学性。然而小学数学教育历来对此不重视,其理由大概是认为小学数学简单,不会出现科学性问题。然而由多年的观察和分析发现,不但教师中存在许多错误观点,小学数学教材中也有不少问题。问题最多的是分数部分,下面我们谈几个主要的问题。 The primary problem of mathematics education is the scientific nature of the teaching content itself. However, primary school mathematics education has always paid no attention to it. The reason is probably that primary school mathematics is simple and there are no scientific problems. However, many years of observation and analysis have found that not only many mistaken ideas exist among teachers, but also many problems in primary school mathematics textbooks. The problem is the fractional part, here we talk about several major issues.
