A German exercise generating system for autonomous learners, utilizing a database in an a la carte method

我们开发了一个在线德语语法学习系统DGSG。该系统有自己的数据库，由3,800个语法练习组成，根据158个语法问题及其主题形式等进行多重分类，DGSG利用这些信息在每个项目上标记，使教育者能够以点菜的方式满足学习者对练习问题，类型和大小的各种需求。并生成具有各种反馈和支持功能的在线自动评分练习/测试，两者都配备有声音和翻译按钮。通过DGSG，教师可以为支持日本德语学习者的各种自主学习做出贡献。

We developed an online German grammar learning system, DGSG. This system has its own data base, consisting of 3,800 grammatical exercises, which are multiply-classified according to 158 grammatical issues, their subject forms, and so on. Using such information tagged at each item, DGSG enables educators to meet the learners' various needs in exercise issues, types, and sizes, in an a la carte method, and to generate online automatic grading exercise/tests with various types of feedback and support functions, both equipped with sound and translation buttons. With DGSG, teachers can contribute to supporting autonomous learning of various types for learners of German in Japan.
