Grading Argumentative Essays: Is Matsu a Hero in The Samurai's Garden?
Published on October 1st, 2026 by the GraideMind team
Asking whether Matsu is a hero is a strong argumentative prompt because the novel supports more than one answer. He cares for Sachi, tends the garden with devotion, and offers Stephen quiet guidance, yet he also keeps secrets and avoids difficult conversations. Students who take a position must weigh these details and defend their interpretation.

Argumentative essays differ from traditional literary analysis because they require students to anticipate objections. Many students struggle to acknowledge the opposing view without undermining their own. Teachers need a rubric that rewards balance and logical reasoning.
The prompt also forces students to define what a hero is, which is often skipped. Without a definition, the argument becomes a matter of opinion rather than analysis. Strong essays set criteria early and use them to evaluate the character.
Key Elements of an Argumentative Rubric
The rubric should assess claim, definition of terms, evidence, counterargument, and reasoning. A student who argues that Matsu is heroic because he protects others at personal cost must explain what counts as heroism and show where the novel supports it. A strong essay also acknowledges that his secrecy complicates the picture and responds to that complication.
- Claim: takes a clear and defensible position
- Definition: explains what heroism means in the essay
- Evidence: uses specific scenes that support the position
- Counterargument: addresses a reasonable opposing view
- Reasoning: connects evidence to the claim with logical explanation
Strong arguments do not ignore the other side; they answer it.

Students often treat counterarguments as a box to check, mentioning an opposing view in a single sentence. Model how to present the best version of the other side and then respond with evidence. Practice with a class debate or a written exchange between two perspectives can make the structure clearer.
When grading, look for whether the response actually addresses the objection rather than changing the subject. A comment such as "you mention that Matsu keeps secrets; explain why that does or does not weaken your claim" guides the student toward real engagement. This kind of feedback improves reasoning, not just structure.
Grading Opinions Without Bias
Teachers may have strong feelings about Matsu, so it is important to grade the argument rather than the conclusion. An essay claiming that Matsu is not a hero can earn full credit if the reasoning and evidence are strong. Make this expectation clear to students so they feel free to take a position.
Using a consistent rubric and, where appropriate, an AI grading assistant can help reduce unconscious bias. A tool like GraideMind evaluates structure and evidence the same way for every essay, and teachers can review the scores to confirm fairness. This protects students who take less popular positions.
Extending the Assignment
After grading, consider hosting a short discussion where students share their positions and respond to each other. Hearing different readings of the same character demonstrates that literature supports multiple interpretations when evidence is strong. This reinforces the skills developed in the essay.
You can also invite students to revise their argument after listening to peers. Revisions that respond to new perspectives show growth in reasoning. These assignments help students become more thoughtful writers and more open-minded readers.
