Plagiarism and Grading

Information about grading student writing also appears in the Grading Student Work section of the Teaching Guide. Here are some general guidelines to keep in mind when grading student writing.

Grade for Learning Objectives

Know what the objective of the assignment is and grade according to a standard (a rubric) that assesses precisely that. If the purpose of the assignment is to analyze a process, focus on the analysis in the essay. If the paper is unreadable, however, consult with the professor and other GSIs about how to proceed. It may be wise to have a shared policy about the level of readiness or comprehensibility expected and what is unacceptable.

Response to Writing Errors

The research is clear: do not even attempt to mark every error in students’ papers. There are several reasons for this. Teachers do not agree about what constitutes an error (so there is an unavoidable element of subjectivity); students do not learn when confronted by too many markings; and exhaustive marking takes way too much of the instructor’s time. Resist the urge to edit or proofread your students’ papers for superficial errors. At most, mark errors on one page or errors of only two or three types. One approach to avoid the temptation of marking every error is to read or skim the whole essay quickly once without marking anything on the page – or at least, with very minimal marks. Some instructors find this a useful method in order to get a general sense of the essay’s organization and argument, thus enabling them to better identify the major areas of concern. Your second pass can then focus more in-depth on a few select areas that require improvement.

Commenting on Student Papers

The scholarly literature in this area distinguishes formative from summative comments. Summative comments are the more traditional approach. They render judgment about an essay after it has been completed. They explain the instructor’s judgment of a student’s performance. If the instructor’s comments contain several critical statements, the student often becomes protective of his or her ego by filtering them out; learning from mistakes becomes more difficult. If the assignment is over with, the student may see no reason to revisit it to learn from the comments.

Formative comments, on the other hand, give the student feedback in an ongoing process of learning and skill building. Through formative comments, particularly in the draft stage of a writing assignment, instructors guide students on a strategic selection of the most important aspects of the essay. These include both what to keep because it is (at least relatively) well done and what requires revision. Formative comments let the student know clearly how to revise and why.

For the purposes of this guide, we have distinguished commenting on student writing (which is treated here) from grading student writing (which is treated in the Teaching Guide section on grading). While it is true that instructors’ comments on student writing should give reasons for the grade assigned to it, we want to emphasize here that the comments on a student’s paper can function as instruction, not simply as justification. Here are ten tips.

1. Use your comments on a student’s paper to highlight things the paper accomplishes well and a few major things that would most improve the paper.
2. Always observe at least one or two strengths in the student’s paper, even if they seem to you to be low-level accomplishments — but avoid condescension. Writing is a complex activity, and students really do need to know they’re doing something right.
3. Don’t make exhaustive comments. They take up too much of your time and leave the student with no sense of priority among them.
4. Don’t proofread. If the paper is painfully replete with errors and you want to emphasize writing mechanics, count the first ten errors on the page, draw a line at that point, and ask the student to identify them and to show their corrections to you in office hours. Students do not learn much from instructors’ proofreading marks. Direct students to a writing reference guide such as the Random House Handbook.
5. Notice patterns or repeated errors (in content or form). Choose the three or four most disabling ones and direct your comments toward helping the students understand what they need to learn to do differently to correct this kind of error.
6. Use marginal notes to locate and comment on specific passages in the paper (for example “Interesting idea — develop it more” or “I lost the thread of the argument in this section” or “Very useful summary here before you transition to the next point”). Use final or end comments to discuss more global issues (e.g., “Work on paragraph structure” or “The argument from analogy is ineffective. A better way to make the point would be…”)
7. Use questions to help the student unpack areas that are unclear or require more explanation and analysis. E.g.: “Can you explain more about what you mean by “x”?”; “What in the text shows this statement?”; “Is “y” consistent with what you’ve argued about “z”?” This approach can help the student recognize your comments less as a form of judgment than a form of dialogue with their work. As well, it can help you avoid “telling” the student how they should revise certain areas that remain undeveloped. Often, students just need a little more encouragement to focus on an area they haven’t considered in-depth or that they might have envisioned clearly in their head but did not translate to the page.
8. Maintain a catalogue of positive end comments: “Good beginning for a 1B course.” “Very perceptive reading.” “Good engagement with the material.” “Gets at the most relevant material/issues/passages.” Anything that connects specific aspects of the student’s product with the grading rubric is useful. (For more on grading rubrics, see the Grading section of the Teaching Guide.)
9. Diplomatic but firm suggestions for improvement: Here you must be specific and concrete. Global negative statements tend to enter students’ self-image (“I’m a bad writer”). This creates an attitudinal barrier to learning and makes your job harder and less satisfying. Instead, try “The most strategic improvement you could make is…” Again, don’t try to comment on everything. Select only the most essential areas for improvement, and watch the student’s progress on the next draft or paper.
10. Typical in-text marks: Provide your students with a legend of your reading marks. Does a straight underline indicate “good stuff”? Does a wavy underline mean something different? Do you use abbreviations in the margins? You can find examples of standard editing marks in many writing guides, such as the Random House Handbook.
11. The tone of your comments on student writing is important to students. Avoid sarcasm and jokes — students who take offense are less disposed to learn. Address the student by name before your end-comments, and sign your name after your remarks. Be professional, and bear in mind the sorts of comments that help you with your work.

Plagiarism and Grading

Students can be genuinely uninformed or misinformed about what constitutes plagiarism. In some instances students will knowingly resort to cutting and pasting from unacknowledged sources; a few may even pay for a paper written by someone else; more recently, students may attempt to pass off AI-generated essays as their own work. Your section syllabus should include a clear policy notice about plagiarism and AI so that students cannot miss it, and instructors should work with students to be sure they understand how to incorporate outside sources appropriately.

Plagiarism can be largely prevented by stipulating that larger writing assignments be completed in steps that the students must turn in for instructor review, or that students visit the instructor periodically for a brief but substantive chat about how their projects are developing, or that students turn in their research log and notes at intermediate points in the research process.

All of these strategies also deter students from using AI to substitute for their own critical thinking and writing. In addition, you may want to craft prompts that are specific to the course materials rather than overly-general ones; and you may also require students to provide detailed analysis about specific texts or cases. AI tools like ChatGPT tend to struggle significantly in both of these areas.

You can also find more information and advice about AI technology like ChatGPT at the Berkeley Center for Teaching & Learning.

UC Berkeley has a campus license to use Turnitin to check the originality of students’ papers and to generate feedback to students about their integration of written sources into their papers. The tool is available in bCourses as an add-on to the Grading tool, and in the Assignments tool SpeedGrader. Even with the results of the originality check, instructors are obligated to exercise judgment in determining the degree to which a given use of source material was fair or unfair.

If a GSI does find a very likely instance of plagiarism, the faculty member in charge of the course must be notified and provided with the evidence. The faculty member is responsible for any sanctions against the student. Some faculty members give an automatic failing grade for the assignment or for the course, according to their own course policy. Instances of plagiarism should be reported to the Center for Student Conduct; please see If You Encounter Academic Misconduct.
