Development and Evaluation of m-Learning Environments to Support Collaborative Learning among Students in Different Places

在这项研究中，我们开发、实施和评估了使用ICT环境的教育实践，以增强学生对月相的理解。日本和澳大利亚的学生参与了这项研究。练习包括三种学习活动：1)观察月亮，记录观察，通过互联网分享和比较记录；2)在电子公告牌上解决问题；3)制作教学工具，以小组活动的形式解释月亮现象。根据分析结果，证实了实习后学生对月相概念量表的正确回答数量有所增加。对问卷和访谈的分析表明，这些学生对月球的兴趣增加了，通过整个学习活动，他们能够通过将观点从地球转移到宇宙来了解月球。

In this research, we developed, implemented and evaluated educational practices with the use of ICT environments to enhance students' understanding about the moon phases. Students in Japan and Australia participated in this study. The practices consisted of the following three kinds of learning activities : 1) observing the moon, recording of the observation, and sharing & comparing the records via internet, 2) solving problems on the electrical bulletin board, 3) creating a teaching tool to explain the phenomenon of the moon as group work. Based on the result of analysis, it was confirmed that the number of these students' correct answers of LPCI(Lunar Phases Concepts Inventory) increased after the practices. The analysis of responses to the questionnaire and the interview showed that these students became more interested in the moon, and that they were able to understand the moon with shifting the viewpoints from the earth to the cosmos through the whole learning activities.
