A famous novel like And Then There Were None comes with a lot of easy online material. Students can find summaries, character lists, and theme guides in seconds. The prompt you write decides whether they lean on that material or think for themselves.

Broad prompts such as discuss the theme of guilt produce broad essays. Many will sound alike, and they will be tedious to grade. The problem starts with the question, not the students.

Better prompts require a position, specific evidence, and some personal judgment. They also make grading easier, since you know exactly what each essay should do. A good prompt saves time at both ends of the process.

Here are principles for writing them. Each one is simple, and together they change the kind of work you receive. Start with the shape of the question.

Ask a Question That Has More Than One Good Answer

A strong prompt invites debate. Instead of asking what Wargrave's plan says about justice, ask whether the novel treats his plan as justice or as something else, and have students defend the reading with evidence. Students must choose and argue.

• Ask a question with at least two defensible answers
• Require specific scenes or moments from the novel
• Connect the question to a concrete choice a character makes
• Ask students to consider a challenge to their own view
• Add a personal judgment element, such as which reading is more convincing

Design for Traceable Thinking

Add short planning steps that show how a student reached their claim. A one-page outline, an annotated passage, or a quick conference gives you evidence of the student's own thinking. It also makes it easy to spot when the final work does not match the process.

In-class writing components, even brief ones, help verify understanding and build confidence. A ten-minute paragraph written in class gives you a baseline for each student's voice. That baseline is useful when you read the full essay later.

Score for Specificity

Add a rubric row that rewards specific, text-based detail over general statements. Generic essays tend to lack precise references to scenes, and the rubric will reflect that naturally. Students quickly learn that specifics earn points.

A rubric-based grading tool can apply this standard uniformly across a large set. GraideMind, for example, scores against your written criteria, so a lack of specificity shows up in the feedback rather than depending on how tired you are. The teacher still reviews every result.

Refresh Prompts Each Year

Prompts that circulate for years get shared. Change the angle or the constraints each time, even slightly. A new scenario or a new pairing can make the assignment fresh.

Keep a bank of prompts sorted by skill so you can swap them easily. It saves planning time and keeps assignments varied. Over a few years, the bank becomes one of your most valuable teaching resources.
