Ellie Cameron, a widowed mother raising two very different daughters, gives students a strong basis for argumentative writing in Susan Lovell's The Sandpiper. Prompts about whether a parent's protection helps or harms a grown child can generate real debate. Because the subject is personal, students often want to argue from opinion, and teachers must help them anchor their claims in the text.

An argumentative essay about a literary relationship still follows the basic structure of any argument, with a claim, reasons, evidence, and a response to opposing views. The difference is that the evidence must come from the story, and the reasoning must explain how characters' actions support the position. Students who treat the novel as a source of proof, rather than a springboard for opinions, write stronger essays.

Setting up the prompt carefully makes grading easier. A question such as whether Ellie's choices ultimately support or limit her daughters invites a defensible position, while a vague prompt about motherhood invites rambling. Teachers should check that the prompt has at least two reasonable answers, since a prompt with one obvious answer produces repetitive essays.

Evaluating the quality of the argument

A strong argumentative essay takes a clear position and sustains it with logical reasoning. Graders should look at whether each body paragraph advances a distinct reason, whether the evidence actually supports that reason, and whether the essay deals fairly with the other side. These checks help separate confident writing from sound argument.

• A clear, debatable claim about the mother-daughter relationship
• Distinct reasons supported by specific events from the novel
• Fair treatment of at least one opposing interpretation
• Reasoning that explains how the evidence supports the claim
• A conclusion that reflects on what the argument means beyond the book

Handling personal opinion

Mother-daughter relationships are close to many students' lives, and strong feelings can enter their essays. Teachers can acknowledge that personal perspective is a valid starting point while reminding students that the essay needs textual proof. A comment such as "What scene shows this?" gently redirects opinion toward evidence.

It is also important to remain neutral about the positions students take. A teacher who personally believes that Ellie is too protective should grade an essay arguing the opposite on the strength of its reasoning. Using a rubric with defined criteria keeps the focus on the quality of the argument rather than agreement.

Teaching counterargument

Counterargument is often the weakest part of student essays, with many students either skipping it or inventing a weak opposing view they can easily knock down. Teachers can model strong counterarguments by asking students to find the best evidence against their own position. This exercise builds intellectual honesty and produces more convincing essays.

Grading counterargument fairly requires clear descriptors. Rubric language that distinguishes between acknowledging an opposing view, responding to it, and using it to refine the thesis helps students aim higher. Feedback can then point to the specific level the student has reached and what the next level would involve.

Making argument feedback scalable

Evaluating argument structure across a full class takes patience, since each essay must be checked for claim, reasons, evidence, and counterargument. AI-assisted feedback tools can map these components for each essay and highlight missing elements. The teacher can then validate the analysis and add comments that reflect classroom conversations and personal knowledge of the student.

This approach is particularly useful in programs with several sections taught by different instructors. Everyone can apply the same argument criteria, which makes grades more comparable across classrooms. Students benefit from clearer and more consistent expectations as they build their writing skills.
