"How do you respond to students writing" summary

In this video three teachers discuss how they respond to their student's writing. Tinberg says that he tries to be aware of the audience while reading a student's paper. Early in his career he was very strict with his grading and very particular with minute details. Since then he has learned to be more constructive with his comments on a student's paper. His comments are either summative or formative. They either rationalize the given grade or advise the student on what they can do to improve their paper in its next revision. Sanchez makes it certain to give back very general comments. He doesn't want his students to feel that being a successful writer is the same as pleasing their professor. He supports Bartholomae and is very clear with his feedback in order to help the student achieve their goal. He focuses on differing between evaluating and responding whenever he's grading a student's paper. Sommers claims that the argument is important to keep in mind when grading a paper. She struggles with whether or not she should comment on every error or just the major ones. She doesn't want to be viewed as an inadequate teacher. She tries to be sure that all her feedback has a purpose and she makes a distinction between rough draft comments and final draft comments. Sommers also highly values feedback from her students. She wants to know how they feel about her comments and how she may improve to become more clear or constructive.
