Traditional grammar instruction takes an isolated approach. It describes the rules for conjugating verbs, un-dangling participles, and coordinating conjunctions. This is done in isolation, apart from real writing and speaking. This approach may be effective for completing grammar worksheets, but it does not address the process of communicating effectively. In other words, teaching grammar instruction apart from real writing does little to enhance the quality of students’ writing. Also, there is very little transfer into authentic writing and speaking.
Instead, the rules of grammar should be taught in the context of students’ own writing. This is called an embedded approach. This is more impactful on students’ ability to use grammar correctly than teaching them in isolation, and it doesn’t get in the way of their real writing.
