The problem with PEEL is that you don’t see pure examples of it outside of school. Writers do make points, they provide evidence and explanation, and they do link their ideas—but they usually do these in a more fluid and varied way than the PEEL formula suggests.
So you should always think critically about strategies and structures like PEEL; they have merit, but they are not the end goal. What we really want is clear, compelling and expressive writing.
