This reviews the 1971 study that is foundational to a Communicative Approach and that started the communicative testing movement. It defines communication, lists the principles of a communicative approach, and briefly reviews everything new about this approach. 40+ years ago, Sandra Savignon warned that we'd slap new labels on old approaches and would not align with what we know about second language acquisition, unless we considered and influenced teacher beliefs and feelings. Share this video and start the dialogue, so that Savignon's words aren't still relevant another 40 years from now. This is the much-abridged version of Acquisition Classroom Memo (Issue 13).
