In case the Moodle download is not working, here is the PDF for my lecture on learning language in class (Part 2). 

We can promote SLA through interaction, negotiating for meaning and creating comprehensible input (i + 1). In this process, we may or may not be ready to acquire some grammar points. We possess this readiness or teachability because we acquire grammar points in predictable sequences. As we acquire through i + 1, we can deliberately focus on grammar at the end (inductively) after using it in real communication, and lastly we can acquire language as we focus primarily on meaningful messages through content-based instruction.
