A Study of the development of a map teaching materials system and a teaching method using the system for elementary and junior high schools

本研究检验了我们开发的地图教材系统是一种有效的教学方法。学习者可以在地图上以图例数据和网格地图数据的形式表示地理知识。通过使用这种格式，从个人层面到班级层面，再到校际层面的网格数据的组合和重用成为可能。一名小学生和一名小学教师是该系统的用户。本系统采用地理信息作为教材的主题，地理信息适用于各个领域。该系统使用地理调查研究所的Cyber Japan Map system提供的地理信息生成地图，并叠加系统定义的网格。协作学习的练习如下：一个班的学生一起合作绘制土地使用网格图，这是地图的典型用法。该系统为他们提供了方便绘画的功能。完成的网格图以作品集的形式存储，即系统中协作学习的成果。作品集可以通过互联网作为教学材料在其他班级或学校共享。本系统为教材的连续制作提供了如下功能。类或用户可以通过Internet在系统中找到合适的投资组合，然后可以使用这些函数从合适的投资组合中派生出新的投资组合。新的投资组合也可以是派生的起源。该系统自2004年1月起开放。二百一十张网格图由不同的用户在系统中注册。网格图不仅包括土地利用图，还包括危害图和萤火虫分布图。这些事实表明，该系统是有用的和通用的。

In this study we examined that the map teaching materials system which we developed was an effective for teaching method. A learner can represent geographical knowledge on a map as a legend data and a mesh map data on the system. By using this format, combination and reuse of mesh data, from personal level, to class level and then to inter-school level, are possible. A pupil and a teacher of an elementary school are users of the system. Geographic information, that is applicable to various fields, is adopted as the subject of teaching material of the system. The system uses geographic information provided by the Cyber Japan Map System of the Geographical Survey Institute to generate a map, and overlays meshes defined by the system. An exercise of collaborative learning is the following; Pupils in one class collaborate with together to paint mesh map of land use that is a typical use of a map. The system provides functions for they to paint easily. Completed mesh map is stored as a portfolio, i.e., fruits of collaborative learning in the system. A portfolio can be shared as teaching materials in other classes or schools through the Internet. The system provides functions for continuous production of teaching materials as follows. A class or a user may find a suitable portfolio in the system through in the Internet, and then may derive a new portfolio from the suitable portfolio using the functions. The new portfolio can be an origin of derivation, also. The system is open since January, 2004. Two hundreds and ten mesh maps are registered by various users in the system. The mesh maps include not only land use maps but also hazard maps and a distribution map of a firefly. These facts indicate that the system is useful and versatile.
