Presentation DynaWrite: Computerized Dynamic Assessment for L2 Writing more

This presentation introduces the results of an online web application we designed to leverage large language models to provide language learners with real-time feedback on learner writing. The tool, called DynaWrite, is designed to deliver feedback that begins implicitly and gradually increases in explicitness if the learner is unable to identify and correct errors, thereby utilizing the benefits of dynamic assessment. While the benefits of dynamic assessment are well-documented and proven empirically, its implementation in real-life classrooms has been limited due to its lack of scalability. Computerized dynamic assessment (CDA) offers a scalable solution, yet previous CDA systems focused on the receptive skills of reading and listening. To the best of our knowledge, DynaWrite is the first CDA system to address grammatical errors in extended writing, addressing an important gap. In this presentation we first provide a brief explanation of how the tool is used and the educational theories underpinning the approach. We then present examples of the tool tracking the development of adult Japanese language learners as they use the tool over a course of English language study.
