地理学科中有许多内涵和外延比较接近的概念,多数学生对这类概念不易真正弄清楚,致使使用时经常出现模棱两可、莫衷一是的现象。为帮助学生更好地掌握此类概念,我尝试将一些常见的学生容易混淆的地理概念制作成了电子词典,并以网页的形式发布到校园网上,供全校师生阅读查询。电子词典共有两大模块,即词典的维护管理和阅读查询。通过“管理”模块把地理概念的相关数据添加到数据库,同时也可定期进行修改或删除。在“查询”模块中可根据需要进行精确查询和模糊查询。其原理可简略表示如下图:
There are many conceptions and extensions of geography that are relatively close to each other. Most students are not able to really understand such concepts, resulting in ambiguous and unresolved phenomena. To help students better grasp such concepts, I tried to make some common geography concepts easily confusing students into electronic dictionaries, and published in the form of web pages to the campus online for teachers and students to read the query. There are two major modules in the electronic dictionary, namely the maintenance and reading of the dictionary. The data related to geographic concepts is added to the database through the “management” module, and can also be modified or deleted on a regular basis. In the “Query” module, you can make precise and fuzzy queries as needed. The principle can be briefly represented as follows:
