认识观念问题 先从一道考题说起。1995年高考语文第31题,按要求续写句子,是道较易答的题,但失分率很高。据一考场抽样检查,满分率为零,得零分者占27％。出人意料的是有近1/3的考生并不是错在对内容的判断或不会表述上,而是将35.8万到64 8万增加了29万,错说成为9万、30万、39万、19万等。看来是错在两数之差上,如果说这些考生的减法“不过关”,怕不能令人信服;若说不是数学问题,到底和语文教学有什么关系呢?
To understand the concept of problems Start with an examination question. In the 31st question of the Chinese language in the college entrance examination in 1995, it was easier to answer the question to write the sentence as required, but the score was high. According to a sample examination in the examination room, the full-scale rate is zero, and 27% of the scorers are zero. Surprisingly, nearly one-third of the candidates were not mistaken in judging their content or not. Instead, they added 305,800 to 680,000 to 290,000, wrongly claiming 90,000, 300,000, 390,000. 19 million and so on. It seems that the difference between the two figures, if the candidates said that the subtraction “but off,” for fear not convincing; if it is not a mathematical problem, in the end and language teaching what is the relationship?
