A mock trial is one of the most popular activities built around "Monster," because students already know the courtroom setting and the central question of Steve Harmon's guilt. The performance is fun, but much of the learning happens in the written pieces that surround it, such as opening statements, witness questions, and closing arguments. Without a clear plan, grading all of that writing can quickly become overwhelming.

The first step is deciding which pieces of writing count for a grade. Most teachers choose one or two individual written products, such as a closing argument or a legal brief, and treat the rest as preparation. Grading everything individually creates far more work than it is worth, and it can pull attention away from the main learning goals.

Roles matter too. A student playing a defense attorney and a student playing a prosecutor will write very different documents, yet both should be judged against the same underlying skills, such as clear reasoning and effective use of evidence from the text. A shared rubric with role-specific notes keeps grading fair.

Rubric Criteria for Closing Arguments

A closing argument is essentially a persuasive essay delivered aloud, so the strongest rubric criteria mirror argument writing. The student should state a clear position, marshal specific evidence from the story, anticipate the other side, and end with a memorable summary. Because the audience is a jury, students should also be graded on how well their language fits that persuasive setting.

• A clear central argument stated early
• Evidence drawn from testimony and events in the book
• Direct response to the opposing side's strongest points
• Persuasive but respectful language suited to a jury
• A memorable, well-organized conclusion

Grading Group Work Fairly

Mock trials are collaborative, which complicates grading. A shared team score can hide who did the writing, while individual scoring can miss the benefits of teamwork. Many teachers solve this by pairing one shared preparation grade with a separate individual writing grade based on a personal written product.

Asking each student to submit a short written reflection on their own contribution adds another layer of information. The reflection should describe what they wrote, what evidence they chose, and what they would change next time. This creates accountability without requiring you to observe every conversation in every group.

Where AI Grading Saves Time

The written components of a mock trial multiply quickly, especially if you teach several classes. AI grading tools can score arguments against your rubric and provide draft comments on clarity, evidence, and structure, which you can review before returning them. This makes it realistic to give individual feedback even when the unit involves many separate documents.

Just as important, the tool helps you keep standards consistent across teams. If one group receives more generous scoring simply because you read their work first, students notice, and trust in the activity suffers. Consistency is a quiet but essential part of a successful mock trial.

Connecting the Trial Back to the Novel

After the mock trial ends, ask students to write a short reflection comparing their courtroom experience to the trial in the book. What did the written arguments make easier to see about Steve's situation, and what did they leave out? This brings the activity back to literary analysis rather than letting it remain a stand-alone event.

Students often produce surprisingly thoughtful writing in these reflections because they now have firsthand experience of how arguments are constructed. Grading that reflection gives you a clear window into what they learned. It also makes the whole unit feel more connected and purposeful.
