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

本研究的主要研究内容如下：（1）采用实验的方法考察了图形支持对应用题解决的促进作用。结果，当五年级学生将问题表征融入他们的数学知识时，他们可以很容易地解决每个单词问题。(2)五年级和六年级的学生在关系图组和关系图组的表现优于五年级和六年级的学生在图表组和控制组。关系图片组和关系图片组的学生通过建立心理模型，更容易理解比例词问题的部分整体关系。(3)当五年级学生使用本研究所开发的计算机辅助教学软件来学习比率应用题时，他们比其他没有接受该软件环境的五年级学生解决了一些困难的应用题。

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.
