Historical argument essays are the assignment Loewen's readers should be writing: a claim about the past, defended with evidence. They are also among the trickiest essays to grade. Two students can cite the same facts and produce very different quality of thinking.

A reliable process starts with a consistent order of reading. Look at the thesis first, then evidence, then reasoning, then organization. Following the same order every time keeps your attention where it matters.

Grade in short passes instead of one long read. A quick first pass gives you the overall shape. A second pass on the middle paragraphs is where you evaluate how well the evidence actually supports the claim.

The sections below describe what to look for at each stage.

Evaluating the Thesis

A strong thesis makes a claim that someone could reasonably dispute. "The Civil War had many causes" does not qualify. "Economic dependence on slavery was the primary driver of secession, more than states' rights arguments" does.

• Is the claim specific to the question asked?
• Could a reasonable person disagree with it?
• Does it preview the reasoning the essay will use?
• Is it stated clearly early in the essay?
• Does the rest of the essay actually support it?

Evidence and Reasoning

Check evidence for accuracy, relevance, and specificity. Then check the reasoning: does the student explain how each piece of evidence supports the claim? Evidence without explanation is the most common flaw and the one most worth commenting on.

Watch for evidence that actually contradicts the thesis and is ignored. Strong students acknowledge it and explain why the claim still holds. That is the mark of real historical thinking.

Writing Useful Comments

Limit comments to the two or three issues that will help most on the next essay. A page full of margin notes overwhelms students and hides the important points. Name the problem, point to an example, and suggest a fix.

AI-assisted grading can draft this kind of comment for each criterion, which you then trim and personalize. It is a useful way to keep feedback specific across a large stack without losing your voice.

Staying Consistent Over a Long Stack

Fatigue changes scoring. Re-read your first few graded essays after the halfway point to check whether your standards have drifted. If they have, adjust before returning anything.

Take breaks, shuffle the order, and grade one criterion at a time when possible. These habits cost little and improve fairness. Students can tell when the last paper got the same attention as the first.
