I work in the field of computer-assisted language learning (CALL)
. My research addresses the urgent societal need of improving language learning, teaching, and assessment practices by taking advantage of new technological opportunities.
I design new types of CALL systems that are adaptive
(i.e. provide personalized learning experiences based on individual student's needs), scalable
(i.e. reduce the time teachers need to spend creating instructional materials), and most importantly, effective
in helping students attain language-learning goals.
The systems that I have developed leverage natural language processing (NLP), real-time biometric measurement of learner behavior, and learner modeling to create pedagogical interventions that would be impossible without these technologies.
My main focus has been on English as a second or foreign language (ESL/EFL)
. My scholarship is broadly organized in three strands: writing
, and pronunciation
