This study reports on how language teachers in preparation integrate key concepts from second language acquisition (SLA) theory into CALL curricular design. The need for language teachers who have had SLA coursework to receive orientation to student-centered learning in a CALL context has been identified previously (Kessler, 2010). This research is intended to provide insight into the ways that students can more effectively design CALL environments with activities that are based on SLA-informed pedagogy. The suggestion is made that in order to successfully integrate SLA theories and CALL, not only is it beneficial for SLA principles to be incorporated into CALL courses but also for SLA theory courses to address the opportunities that CALL may offer for integrating SLA principles within the language classroom.
