English as a New Language (ENL); English Language Development (a.k.a. English as a Second Language (ESL); Designated ESL; Stand-Alone ESL/ENL; or, Focused Language Study) takes a variety of forms in present-day schools. In many schools, teachers teach ENL for a set amount of time (e.g., 30 minutes) a day. Other ENL teachers have multiple classes each day. In many cases, teachers think that they need to focus solely on grammar and vocabulary. However, emphasizing grammar and vocabulary is not the most effective for lasting and engaging language learning. Language was created to get things done, to communicate – and this is where this MOOC starts. It focuses on how to design and teach activities that are saturated with communication, and where needed, strategically develop grammar and vocabulary to support communication.
