The quality of a Dune essay starts with the prompt. A broad question like "discuss the themes of Dune" invites a book report in disguise. A sharper question pushes students toward a claim you can actually evaluate.

Prompt design is one of the most underrated parts of grading. When the prompt is tight, essays cluster around a manageable set of arguments, and your rubric can be specific. When it is loose, every essay is a special case.

Prompts also affect how easily a student can bluff. If a question can be answered with a generic paragraph about power corrupting people, some students will do exactly that. Questions that require specific scenes and choices are harder to fake.

The prompt types below are built with grading in mind. Each one has a natural rubric attached, so you know what strong and weak responses will look like before the papers arrive.

Prompt types that produce gradable arguments

Prompts that ask students to take a position and defend it tend to work best. Something like whether Duke Leto's decisions contributed to his family's downfall gives students a debatable claim and forces them to use specific events. You can score the argument, the evidence, and the reasoning separately.

• Choice prompts: ask which single decision in the novel mattered most and why
• Contrast prompts: compare how two characters respond to the same pressure
• Symbol prompts: trace what water means across the Fremen and Atreides storylines
• Turning point prompts: argue where Paul's transformation actually begins
• Evaluation prompts: judge whether a leader's authority is earned or manufactured

Matching each prompt to a rubric

Before you assign a prompt, write two sentences describing a strong response. If you cannot, the prompt is probably too vague. Those two sentences become the top row of your rubric.

Then describe what a middling response looks like, usually a claim that is correct but generic. That contrast gives you the language to explain scores to students without a long conversation.

Making prompts harder to game

Ask for specific scenes, not just themes. Requiring students to build an argument around two or three moments from the text limits how much a summary or a borrowed argument can help them.

You can also add a small twist that changes each semester, such as a required counterargument or a specific chapter range. Small variations keep old essays from circulating.

Testing prompts before the whole class writes

Try the prompt yourself in ten minutes of outlining. If the outline comes easily, the prompt is probably answerable. If you get stuck, students will be too.

Run a few sample responses through your rubric, or through a rubric-based feedback tool like GraideMind, to see whether the criteria separate strong and weak writing. If everything lands in the same band, tighten the prompt.
