The Curious Incident of the Dog in the Night-Time was adapted for the stage by Simon Stephens, and many classes read the novel and then watch or read the play. A comparison essay invites students to think about how a story changes when it moves from page to performance. The assignment can be rich, but only if the grading criteria make clear what a strong comparison looks like.

The central difficulty is that the novel gives access to Christopher's thoughts through first-person narration, while a play must show them through staging, movement, and dialogue. Students who recognize that difference can write sophisticated analysis. Those who simply list scenes that appear in one version and not the other produce a summary that says little about adaptation itself.

Decide whether the essay should focus on a single scene, a particular theme, or the overall effect of adaptation. A narrow focus produces more detailed analysis and makes grading easier. Broad prompts tend to produce scattered essays that touch many points without developing any of them.

Define What Counts as Evidence

Because two texts are involved, evidence requirements need to be explicit. Students should cite specific moments from the novel and specific choices in the play, whether from the script or a viewed performance. A rubric criterion that requires balanced and accurate evidence from both versions prevents lopsided essays.

• A thesis that makes a claim about what changes or stays the same in adaptation
• Specific evidence from both the novel and the stage version
• Analysis of how form, such as narration versus staging, shapes the audience's experience
• Discussion of at least one meaningful difference and one meaningful similarity
• Accurate use of terms related to drama and fiction where appropriate

Address Accessibility and Viewing Conditions

Not every student will see a live performance, and recordings or scripts may differ in availability. State clearly what source students should use so that everyone works from the same material. Fairness requires that no student is disadvantaged by access to a particular production.

If you use a script, remind students that stage directions are part of the text and can be cited as evidence. If you use a recording, ask them to describe specific staging choices rather than general impressions. Precision in the sources leads to precision in the essays.

Give Feedback on the Comparison Structure

Structure is a common weak point in comparison essays. Students may devote half the paper to the novel and half to the play, leaving the actual comparison to a short conclusion. Feedback should encourage organization around ideas, with each paragraph examining one point across both versions.

A helpful comment might ask the student to merge two separate paragraphs into one that considers how the train journey is presented in each form. This pushes them toward direct comparison and away from parallel summaries. It also gives them a concrete revision task.

Keep Grading Efficient

Comparison essays require careful reading because evidence comes from two sources, and verifying accuracy takes time. A rubric-aware tool can help by checking each essay against the criteria and flagging missing elements, such as the absence of evidence from one version. The teacher confirms and refines the feedback, saving significant effort.

That time is better spent discussing the more interesting questions students raise. Adaptation invites debate about whether a stage version can capture a narrator's inner world. A teacher with energy left over can engage with those ideas rather than just marking errors.
