In this Specialist Master Class, English Language Specialists Alicia Brent and Lisa Donohoe share their experience in developing an ESP course using a content-based instruction (CBI) approach for teaching English Communication for Disaster Management (ECDM). To receive a course certificate, participants complete a final project in which they write an elevator pitch for potential stakeholders to convince them to launch an ESP course on a topic and for an audience of the participants’ choosing.
