中国与新加坡初中数学教材中统计习题的比较研究

Comparison on Statistic Exercises in Mathematics Textbooks for Junior Middle School between China and Singapore

从习题的数量、数学认知水平两个维度,对中国初中数学教材和新加坡初中数学教材中统计内容的各类习题进行比较分析,发现:中国教材统计习题总量较少,但课后习题的编排具有层次性;中国教材中高认知水平的习题比新加坡少;中国教材重视基本概念,而新加坡教材设置了较多的非常规习题,重视高认知水平的培养.

From two dimensions of the number and the mathematics cognitive level of exercises, we compare and analyze different types of statistic exercisesin mathematics textbooks for junior middle school between China and Singapore. We found that the total of statistic exercises in textbook of China is less than Singapore’s, but the textbook of China outstands different arrangement levels in schedule of exercises, the total of exercises of high cognitive level in textbook of China is less than Singapore’s, the textbook of China gives full attention to basic conception, but the textbook of Singapore sets more unconventional problems, paying more attention to developing student’s high mathematics cognitive level.
