Here is a copy of a handout that I use for Common Errors in Writing. These are errors that I see repeated by my upper level students. I use this as an introduction to help them prepare for the Presentational Writing section of the AAPPL Test, so there is an included AAPPL Writing Rubric that I use. It's not perfect but it's the best way that I have found to make sense out of the scores and help them understand the power of their written language.
I've also included a Google Slideshow presentation of some of these errors plus some new ones that I'm seeing this year.
