Argumentative essays work best when students have a question that reasonable readers can answer in different ways. The Princess Diaries provides one in Mia's decision about whether to embrace her royal role. Students can argue that she should accept it, that she should refuse it, or that the choice is more complicated than either option. This variety makes the assignment engaging and gives you real arguments to evaluate.

Make clear that students are arguing about a character's choice, using the text as evidence. Their opinion matters less than the quality of their reasoning, and they must ground claims in what Mia says, does, and values in the novel. This keeps essays from drifting into unsupported opinion about what the student would do.

Teach students the components of a strong argument before they write. These include a clear position, reasons supported by evidence, acknowledgment of a counterargument, and a response to that counterargument. A model paragraph showing how to concede a point and then rebut it helps students understand what this looks like in practice.

Rubric criteria for argument essays

Your rubric should assess the clarity of the position, the strength of the reasoning, the use of evidence, and the handling of counterarguments. Each criterion should include observable descriptors so scoring remains consistent. Avoid giving credit simply because you agree with the student's position, and instead evaluate how well the argument is built.

• Position is stated clearly and answers the question directly
• Reasons are distinct and supported by specific moments from the novel
• A counterargument is acknowledged fairly and accurately
• The essay responds to the counterargument with evidence or logic
• The conclusion reinforces the position without simply repeating it

Avoiding bias in grading

When grading argumentative essays, it is easy to favor positions you find more convincing. Counter this by scoring each criterion separately and using the rubric descriptors as your guide. If you notice yourself reacting to the position rather than the argument, pause and return to the evidence.

Anonymous grading, where you cover names or use student numbers, can reduce unconscious bias related to students rather than positions. Reading essays in random order and checking an anchor paper periodically also supports fairness. These practices help ensure that every student's argument receives the same careful consideration.

Providing feedback that strengthens arguments

Useful argument feedback often takes the form of challenging questions. Asking "What would someone who disagrees with you say, and how would you respond" pushes students to engage with the opposition. This type of comment prompts deeper thinking than a directive to add a counterargument.

AI feedback tools can identify essays that lack a counterargument or whose reasons overlap too much, helping you target your comments. You review and refine the output, adding insights based on your understanding of each student. The combination supports faster, more focused feedback on argument writing across a full class.
