Students writing about Hiroshima bring a mix of what they read, what they learned in history class, and what they picked up elsewhere. That mix can produce factual mistakes, from confusing dates to blending the two atomic bombings together. Catching these errors matters, especially in courses where accuracy is part of the assessment.

The challenge is proportion. A wrong date in a strong essay should not sink the grade, but a pattern of misunderstanding can. Deciding where to draw the line requires a clear policy.

It also requires you to be sure of your own facts. When a student states something you are unsure about, check before marking it wrong. Nothing undermines feedback faster than correcting a student who was actually right.

Here is how to approach accuracy in a way that is fair and useful.

Decide How Much Accuracy Counts

Build accuracy into your rubric as an explicit category, or fold it into evidence. Say clearly what level of error changes a score. This lets students know what to double-check before they submit.

• Minor slips, such as a small detail misremembered, get a note but little penalty.
• Errors that change the meaning of an argument should affect the score.
• Confusing distinct events, such as the two bombings, deserves direct correction.
• Claims about the book that do not match the text should be flagged.
• Unsupported statistics should prompt a request for a source.

Separate Errors About the Book From Errors About History

A student who misattributes an experience to the wrong survivor has made a reading error. A student who gets a date wrong has made a historical one. The two call for slightly different feedback, so it helps to label them.

For reading errors, point the student back to the relevant chapter and ask them to check. For historical errors, suggest a reliable reference. Both approaches teach students to verify their own work.

Give Corrections That Teach

A note that says "wrong" is less useful than one that explains what the correct information is and why the mistake matters. If a student confuses two events, a sentence clarifying the difference helps them avoid the error in the future. Keep corrections short and matter-of-fact.

AI feedback tools can help flag statements that look inconsistent with the source text, which is useful when you are reading quickly. Treat those flags as prompts to verify, not as final judgments. Your knowledge of the material remains the last word.

Encourage Verification Habits

Ask students to add a brief note listing any facts they checked outside the book. This small requirement reminds them that accuracy is their responsibility. It also gives you a window into how they research.

Over time, students who develop the habit of verifying claims write more careful and more credible essays. That is a skill that carries well beyond this unit.
