Persuasive writing improves when students care about the question, and Callum McBride supplies plenty of debatable choices. A twelve-year-old who can occupy an animal's mind and direct its actions has to decide when using that power is wise, safe, or fair. Students naturally have opinions about those decisions, which gives teachers a head start on engagement.

The challenge is turning opinion into argument. Students tend to write "I think Callum should" and then repeat the same idea in different words. Teaching them to build a claim, support it with evidence from the text, and address a counterargument transforms a rant into a piece of persuasive writing.

Good prompts name a decision and ask for a position grounded in the novel. Because the book moves through scenes of secrecy, risk, and loyalty, there are plenty of moments where reasonable readers disagree. Choose prompts where both sides have real evidence, so students cannot simply pick the obvious answer.

Prompt ideas worth assigning

Prompts work best when they tie to a specific dilemma and ask students to consider consequences. For example, a prompt could ask whether Callum should trust Emma with his secret early in their friendship. Students must weigh the risk of exposure against the benefit of having an ally, and the text supplies material for both positions.

• Should Callum have told an adult about his ability as soon as he discovered it
• Is it fair for Callum to use his ability to gather information about his past
• Was it wise for Callum to trust Emma so quickly after meeting her
• Should young people be allowed to take risks to stop a serious crime
• Would Callum's life be better or worse without his unusual talent

Rubric design for argument essays

A persuasive rubric should assess claim clarity, quality of reasons, use of textual evidence, treatment of counterarguments, and tone. Counterargument is the row students most often miss, so give it clear weight and a descriptor that distinguishes acknowledging an opposing view from actually rebutting it. This tells students that mentioning the other side is not enough.

Be careful not to penalize a student for taking an unpopular position. The grade should depend on how well the argument is built rather than whether the teacher agrees with it. This principle is worth stating aloud, since students sometimes write what they think the teacher wants to hear.

Teaching evidence and reasoning together

Evidence without reasoning is one of the most frequent weaknesses in argument essays. A student may quote a scene accurately but never explain how it supports the claim, leaving the reader to make the connection. Modeling a quote followed by two sentences of reasoning helps students internalize the pattern.

Practice with a shared class paragraph before individual drafting. Display a weak paragraph with a quotation and no explanation, then revise it together on the board. Watching a draft improve in real time makes the abstract idea of reasoning concrete.

Feedback strategies that save time

When grading a large set of argument essays, prioritize feedback on the claim and the counterargument, since those have the greatest effect on quality. Mark the thesis with a quick note about whether it is arguable, then give one substantive comment on how to strengthen the rebuttal. Students can handle only a few targeted comments at a time.

AI-assisted tools can help by flagging missing counterarguments or unexplained evidence across a whole class set. Teachers can then review those flags and add personal notes where a student needs encouragement. This split between machine consistency and human judgment keeps feedback prompt and meaningful.
