Comparing characters is a natural assignment for Dr. Franklin's Island because the three teenagers respond so differently to captivity and change. Semi, Miranda, and Arthur each bring distinct temperaments to the island, and their contrasts illuminate the novel's larger questions. Students enjoy this task, but the resulting essays can be difficult to grade consistently.

A frequent problem is the list essay, in which a student describes one character in a paragraph and the next character in the following paragraph. The writing may be accurate and well organized, but it never actually compares anything. Your rubric should state that comparison means explaining how characters relate to each other, not describing each in isolation.

Another challenge is deciding what the comparison is for. A strong essay uses its comparison to say something about the novel, such as how different personalities reveal different attitudes toward survival or authority. If the prompt does not demand a purpose, many students will settle for observation.

Judging the quality of the comparison

Look for essays that identify a specific basis of comparison, such as how each character reacts to a particular event or how each handles fear. A shared basis lets the writer place characters side by side and draw meaningful conclusions. Without it, the essay drifts into general description.

• A thesis that makes a claim about what the comparison reveals
• A clear basis for comparison, such as response to danger or loyalty
• Evidence for each character drawn from specific scenes
• Paragraphs organized around points of comparison rather than character by character
• A conclusion that explains the significance of the similarities and differences

Avoiding the one-sided essay

Students often favor the character they like best and give the others less attention. Check whether the evidence is balanced and whether each character receives fair treatment. If the essay is lopsided, feedback should encourage the writer to find parallel moments for the neglected characters.

It is also worth watching for oversimplified labels such as the brave one and the scared one. The novel gives each character more complexity than that, and the best essays notice it. Praise students who show that a character can be both fearful and determined.

Feedback on organization

Comparison essays are often organized in either a block or a point-by-point structure. Point-by-point usually produces stronger comparison because the writer must address both characters within the same paragraph. If a student uses a block structure, a comment can ask them to add a transition that explicitly connects the two halves.

Offer a template sentence frame for students who struggle, such as "While Semi responds to danger by..., Miranda responds by...." Frames like this give them a way into comparative language. After a few attempts, most students begin to write their own.

Streamlining the grading

To save time, scan each essay first for its thesis and structure. These two elements predict the quality of the rest of the paper and help you sort essays quickly. You can then read more closely for evidence and explanation.

AI-based rubric grading can apply this same scan to every essay and generate draft comments about structure and balance. Teachers review the output and add insight about characters that only a reader of the novel could provide. The process saves time without hiding the details that matter.
