Don't ignore your own expertise as a reader and writer in your discipline. Even if you aren't comfortable using grammatical or rhetorical terminology to explain a draft's problem to a student, your experience reading and writing in your field will alert you to problems to highlight for students.
In addition to the information presented in this guide, you can also obtain information from your campus writing center or writing program.
Finally, other guides on this may be helpful, particularly those on the Teaching Resources Page. Please check our teaching guides, and let us know if you have questions or suggestions for additional materials you would like to see us add to this or other WAC Clearinghouse guides.
