Teachers write hundreds of comments each term, yet many of them never change how a student writes. The problem is usually specificity: a comment that could be attached to any essay on any book is rarely helpful. When grading essays on a text like "På vegne av venner" by Kristopher Schau, comments should point to the student's actual sentences and the actual choices they made.

A useful comment has three parts: it names what the student did, explains why it matters, and suggests a next move. For example, noting that a quotation is well chosen but unexplained, and asking the student to add a sentence connecting it to the thesis, covers all three. This structure takes only a few extra seconds once it becomes a habit.

Teachers also benefit from limiting the number of comments per essay. Ten margin notes overwhelm a student, while two or three prioritized ones can guide a real revision. Choosing which issues matter most is itself a form of expert judgment.

Weak Comments and Why They Fail

Comments such as "unclear," "awkward," or "more detail needed" identify a symptom without a cause. Students often respond by changing a word or two and hoping for the best. The revision rarely improves because the comment never explained what was missing.

• Weak: "Add more analysis." Strong: "Explain how this passage shows the narrator's attitude toward his friends."
• Weak: "Good job." Strong: "Your thesis takes a clear position, which makes the rest of the essay easy to follow."
• Weak: "Unclear." Strong: "I cannot tell whether 'this' refers to the quote or your claim; name it directly."
• Weak: "Needs evidence." Strong: "Support this point with one short passage and explain why you chose it."
• Weak: "Awkward." Strong: "Split this sentence in two so the contrast in your argument is easier to see."

Praise That Teaches

Positive comments are not just encouragement; they tell students which behaviors to repeat. Saying that a topic sentence frames the whole paragraph helps the student recognize the technique and use it again. General praise feels pleasant but gives nothing to build on.

Specific praise also builds trust, because it shows the teacher read closely. Students who feel read are more willing to attempt harder revisions. This effect is especially important for reluctant writers.

Building a Comment Bank

A personal bank of common comments, written carefully once and adapted as needed, saves time without lowering quality. Teachers can organize it by rubric criterion so the right comment is easy to find. Over the years, the bank becomes a precise record of the issues students face.

AI-assisted tools can draft comments aligned to the same criteria, which the teacher then reviews and personalizes. This is particularly helpful for large class sets where fatigue lowers the quality of later comments. The teacher remains responsible for accuracy and tone.

Closing the Loop With Students

Feedback only works if students engage with it, so building in a short response task is worthwhile. Asking each student to pick one comment and explain how they would act on it takes five minutes. It also reveals which comments were misunderstood.

Teachers can then refine their wording based on those responses. A comment that repeatedly confuses students should be rewritten. Treating feedback as something to test and improve makes the whole grading process more effective.
