Multimedia CALL: Lessons to be Learned from Research on Instructed SLA

This paper suggests that some design features and evaluation criteria for multimedia CALL might be developed on the basis of hypotheses about ideal conditions for second language acquisition (SLA). It outlines a relevant theory of SLA and enumerates the hypotheses it implies for ideal conditions such as input saliency, opportunities for interaction, and learner focus on communication. Implications of each hypothesis for multimedia CALL design and evaluation are outlined and exemplified
