Asking students to imitate Didion's sentences is one of the most effective ways to teach syntax, rhythm, and control. A student who tries to reproduce her long accumulating sentences, followed by a short blunt one, learns something about pacing that no lecture can deliver. The trouble comes at grading time, when teachers have to decide what counts as a successful imitation. Without clear criteria, the work is scored on impression alone.

The first decision is what the assignment is actually measuring. Some teachers want students to reproduce a structural pattern, such as a series of parallel clauses that ends in a turn. Others want a broader imitation of voice, including diction and attitude. The grading criteria should match the goal, because students will optimize for whatever the rubric appears to value.

A related question is how far students should stray from the model. Direct copying of phrasing is obviously not the goal, but a close structural parallel with entirely new content is often exactly what the exercise intends. Explaining this boundary in advance prevents confusion and reduces integrity concerns. It also keeps the work focused on technique rather than on borrowed words.

Criteria for a fair rubric

A strong rubric for imitation tasks addresses fidelity to the structure, originality of content, and quality of the resulting prose. Each criterion should be described at several levels so that students understand what improvement looks like. For instance, high fidelity means the sentence rhythm and clause pattern clearly echo the model, while high originality means the subject matter is the student's own. Naming both prevents students from trading one for the other.

• Structural fidelity to the chosen model sentence or paragraph
• Original subject matter and specific detail
• Consistent tone that matches the intended effect
• Grammatical control, especially in long or layered sentences
• A brief written reflection explaining the choices the student made

Feedback that teaches technique

The most effective feedback on imitation names the specific feature the student captured or missed. A comment such as "your third clause repeats the rhythm of the first, which softens the final short sentence" points to the mechanics of the effect. Students can then adjust a single element and see the change immediately. General praise about voice, by contrast, teaches them nothing they can reuse.

Because imitation assignments often involve many short pieces, feedback can become repetitive. An AI first pass is well suited to the routine observations about clause structure, repeated words, and sentence length. Teachers can then spend their time on the more interesting comments about tone and effect. This keeps the feedback both timely and thoughtful.

Guarding against shallow mimicry

Some students learn to reproduce surface features, such as an ironic aside or a run of fragments, without understanding why the original writer used them. The written reflection is the best safeguard, since it asks students to explain what their choices accomplish. A student who cannot describe the effect probably did not produce it deliberately. Reading the reflections alongside the imitations gives a much fuller picture of learning.

Consider asking students to write the same content twice, once in their natural voice and once in the imitated style. The comparison shows how syntax alters meaning and emphasis, which is the deeper lesson of the exercise. It also gives graders a baseline for judging whether the imitation actually changed the writing. These paired pieces often produce the most insightful reflections.

Connecting imitation to later writing

The value of imitation is realized when students carry what they learned into their own essays. After the unit, ask them to revise a paragraph from an earlier assignment using one technique they practiced. Score the revision against the same criteria and compare it with the original. The improvement, when it appears, is concrete evidence that the exercise worked.

Keep a running record of which techniques each class found easiest and hardest. Over several terms, this record informs how you sequence the exercises and which model sentences you choose. Teachers often find that students struggle most with restraint, such as ending a paragraph without a moral. Knowing that in advance lets you build targeted practice into the unit.
