Constructing a Data-Driven Learning Tool with Recycled Learner Data

This paper discusses a data-driven learning (DDL) tool, which consists of a learner corpus for L2 learners of German. The learner corpus, in addition to submissions from ongoing current users, has been constructed from millions of submissions from a variety of activity types of approximately 5000 learners who used the E-Tutor CALL system over a period of five years. By following a cyclical process of development, implementation, and evaluation, adapted from the ADDIE model, E-Tutor helped us not only to inform language teaching pedagogy and to provide system enhancements generated by the outcomes of vast data collections, but also to expand an existing learning environment (e.g., Tutorial CALL) to include DDL. The article discusses the cyclical process of collecting and recycling learner data by also focusing on the design features of the DDL tool of E-Tutor within the ADDIE framework and providing data on student usage.
