A longitudinal study of effects of learning strategies and transfer which help children understand and solve word problems

本课题的主要研究结果如下：（1）学生在解决比率应用题时使用了多种学习策略。当学生解决比率字问题，生成图表作为一种学习策略，他们解决困难的比率字问题比学生谁解决他们使用其他学习策略。(2)当我们研究基于计算机的图表解决两种类型的文字问题和迁移测试问题的影响，在一年的时间内，五年级的学生谁已被训练，通过计算机生成图表优于其他组的学生在一年的时间内解决比率文字问题。(3)训练组的五年级学生和其他组的学生一样解决了迁移测试问题。

The main research results of our project were as follows :(1) We showed that students use a variety of learning strategies when they solve ratio word problems. When students solved ratio word problems by generating diagrams as a learning strategy, they solved difficult ratio word problems more than the students who solved them using other learning strategies.(2) When we examined effects of computer-based diagrams on solving two types of word problems and transfer test problems over a one-year period, fifth-grade students who had been trained to generate diagrams via a computer outperformed students in the other groups on solving ratio word problems over a one-year period.(3) Fifth grade students in the training group solved the transfer test problems as well as students in the other groups.
