As Robert Lewis explains, this video is directed toward ESL or ELL students who have to write something like the IELTS essay. He covers the basic questions: What is an essay? and How can we write a simple persuasive essay? Definitions and parts of an essay are explained before a sample prompt is shown. Arguments are first outlined and then written into cohesive paragraphs. The process is not explained but simply shown while Lewis types and reads out loud.
