Open a stack of Père Goriot essays and you will see the same opening claims again and again. "Balzac shows that money is important in society" appears in dozens of forms, and it is true enough that no one could disagree with it. A thesis nobody can dispute is not yet an argument. Feedback on thesis statements is one of the highest-return uses of your grading time because everything else in the essay depends on it.

A strong thesis for this novel makes a claim that a reasonable reader could push back on. For example, a student might argue that Balzac presents Goriot's devotion not as virtue but as a flaw that teaches his daughters to treat love as a transaction. That claim can be tested against scenes, qualified, and defended. It also tells the reader what the rest of the essay will need to prove.

Students rarely write a thesis like that on a first try. They need a sequence of nudges, starting with a topic, then a position, then a reason. You can model this on the board using three versions of the same idea moving from broad to specific. Seeing the progression helps students recognize which stage their own draft is stuck at.

Common Thesis Problems and How to Name Them

Give the problems short names so your comments stay quick and your students can recognize patterns. A "topic only" thesis announces a subject without taking a side. A "plot claim" thesis states something that happens in the story, such as the fact that Goriot dies alone. A "moral verdict" thesis calls a character good or bad without explaining how the text supports that judgment.

• Topic only: names Paris, ambition, or fatherhood without making a claim
• Plot claim: states an event instead of an interpretation of it
• Moral verdict: labels a character without a text-based reason
• Too broad: tries to cover the whole Comédie humaine in five paragraphs
• Disconnected: promises an argument the body paragraphs never deliver

Writing Comments Students Can Act On

Compare two comments on the same thesis. One says "needs to be more specific," which leaves the student guessing. The other says "you claim Vautrin is corrupt; what does he want Rastignac to learn that makes his offer dangerous?" The second comment points to an actual question in the novel and gives the writer a direction to revise.

Questions often work better than instructions because they invite the student to think. Try ending thesis comments with a "so what" or a "how do you know" and let the student draft the answer. When a class is large, a library of short thesis comments that you reuse and tailor saves real time without making feedback feel mechanical.

Scaling Thesis Feedback Across Many Papers

A first-pass thesis check is a good candidate for automation. An AI grading tool can read every opening paragraph, identify which of the problems above applies, and draft a targeted prompt for revision. You review the batch, correct any misreadings, and add personal notes where a student needs encouragement or a sharper challenge. That workflow lets you spend your own attention on the harder interpretive questions.

Consider letting students revise only the thesis and resubmit it for a quick check before they write the full essay. A five-minute review at that stage prevents a week of misdirected drafting. Students who start with a defensible claim produce cleaner body paragraphs and need fewer comments at the end. It shifts feedback from a post-mortem into a working tool.
