Focus On Common Errors

One of the challenges in the teaching of grammar is the fact that students have received different kinds of training and different amounts of training. A presentation on the punctuation of compound sentences -- always a crowd pleaser -- may be "old hat" to some students and a revelation to others. The good news is that a relatively short list of errors in usage, grammar, punctuation, and spelling accounts for almost all the mechanical faults seen in student papers. You may find it helpful to browse sites that feature the 10 or 20 most common mistakes in student writing.
