Reserch on subprocess analyzes of word problem solving with solution strategy support

本课题的主要研究内容如下：(1)通过实验考察图形支持对解题的促进作用。结果，当五年级学生将问题表示融入到他们的数学知识中时，他们可以很容易地解决每个单词问题。(2)图-关系图片组和关系图片组的五、六年级学生表现优于图组和对照组的五、六年级学生。图-关系图组和关系图组的学生通过建立心理模型，可以很容易地理解比例应用题的部分-整体关系。(3)当五年级学生使用本研究项目开发的计算机辅导软件支持学习比例字题时，他们比其他未接受软件环境的五年级学生更能解决某些困难的字题。

The main research of our project were as follows :(1) The experiment was carried out to examine the facilitative effect of word problem solving using the diagram support. As a result, fifth graders could easily solve each word problem when they integrated problem representation into their mathematical knowledge.(2) Fifth and sixth graders in the diagram-relational picture group and in the relational picture group outperformed fifth and sixth graders in the diagram group and the control group. The students in the diagram-relational picture group and in the relational picture group could easily understand the part-whole relation of ratio word problems by building their mental models.(3) When fifth graders studied ratio word problems using the computer-based tutoring software support which were developed by our research project, they solved some kinds of difficult word problems more than the other fifth graders who did not receive the software environment.
