摘要
本研究运用实验法对某普通小学的161名4-6年级学生进行了长方形面积任务和MPI测验，以考察学生的应用题表征水平及其对问题解决的影响。结果表明：（1）表征水平随着年级的升高而不断提高，学生在表征水平上性别差异不显著；（2）无论哪个年级，表征水平都是优等生好于中等生，中等生好于差等生；表征水平越高，学生在问题解决上的成绩越好；（3）随着题目难度的不断加大，各表征水平的学生在解题正确率上的差距也在不断拉大。也就是说，题目越难，表征水平在解题中的作用也就越明显。
The rectangle area task and the MPI test were administered to 161 students from the fourth to sixth grades by an experiment method in order to explore the representational level in math word problem and its influence on problem-solving. The results showed that： （1） the representational level improved with children entering the higher grade, and gender difference was insignificant at the representational level; （2）Regardless of grade, superior pupils were highest at the representational levels. The higher the representational level, the better the test achievement ; （3）With the items becoming more difficult, the difference of test achievement at representational levels got greater.
