Hybrid courses--which replace 20%-80% of class meetings with online activities--are predicted to increase as educators embrace the benefits of blending online technologies with face-to-face class meetings. Also expected to increase are enrollments of ESL/EFL students. As these growth trends intersect, an increased number of ESL/EFL students are expected to enroll in hybrid courses, especially mainstream courses populated by a majority of native-English-speaking students. Despite these growth trends and research showing hybrid courses as positive for most students, the TESOL community has not yet opened a discussion of the implications of hybrid delivery of mainstream classes for ESL/EFL students. In an effort to start the discussion, this article investigates potential problems related to issues of identity, forced individualization, and muting; gives several strategies for instructors of hybrid courses with ESL/EFL students; and concludes by calling for TESOL researchers to focus attention on hybrid delivery.
