データベースを利用したオンライン型テスト・課題生成システムDGSGの機能拡張について

The author and his colleagues, Takako Yoshimitsu and Axel Harting, have been developing an online German grammar exercise-generating system utilizing an exercise database for Japanese learners of German, called DGSG, (Deutsche Grammatikübungen selbst gestrickt!)

The first version of the DGSG and these details were reported in Iwasaki (2009, 2011). But the developing concept of the DGSG in the early stages, namely “a wide use self-learning system which should be independent of any particular German classes and educational facilities" has meanwhile changed into a “self-learning system also suitable for blended learning in German classes in Japanese universities." And, according to the new concept, in the past year and a half a new type of account, “teacher account", was introduced. The function of the DGSG in learning management was also expanded for the sake of instructors who teach German in their classes.

This article reports on the characteristics of the new improvements in the DGSG, and the results of questionnaires filled out by the test users of the DGSG in German classes at Hiroshima University in 2011 and 2012. The new improvements in the system are partly based on those student desires and needs.
