Most problems in student essays on The Apprenticeship of Duddy Kravitz begin at the thesis. Students write sentences like "Duddy is a determined character who wants land," which is accurate but not arguable, and then struggle to build a body that goes anywhere. Teachers see this pattern so often that thesis feedback can feel like a broken record. Yet a thesis is the single most leveraged place to intervene, because a sharper claim improves every paragraph that follows.

The first step is helping students understand what makes a claim arguable. A thesis about Duddy should be something a reasonable reader might dispute, such as whether his ambition ultimately destroys or defines him. If the statement could not provoke disagreement, it is probably a fact or a topic. Showing students a pair of examples, one flat and one debatable, often clarifies the difference faster than a lengthy explanation.

Next, encourage students to include a reason or mechanism in the claim. A thesis that says Richler uses Duddy's treatment of Virgil to show that ambition without conscience leaves a person isolated gives the writer a built-in roadmap. It names the author's technique, the evidence, and the larger point at once. Feedback that nudges students toward this fuller structure produces essays that feel purposeful from the opening paragraph.

Comments that move a thesis forward

Effective thesis comments do three things: they identify what is currently working, name what is missing, and suggest a concrete revision move. For instance, you might write that the claim correctly identifies Duddy's obsession with land but does not yet say what Richler wants readers to think about it. Asking the student to finish the sentence "Richler suggests that..." gives them a manageable task rather than an overwhelming demand to rewrite everything.

• Ask whether a classmate could reasonably disagree with the claim
• Prompt students to add a "because" that names Richler's technique
• Point out when a thesis lists topics instead of making a point
• Check that the thesis can be supported with at least three distinct scenes
• Flag claims that are too broad to prove in a five-paragraph essay

Common thesis mistakes in this unit

One frequent mistake is the moral verdict without reasoning, such as declaring that Duddy is simply a bad person. While a strong essay might ultimately judge him harshly, the thesis needs to explain by what standard and with what evidence. Another common issue is the over-ambitious claim that tries to cover Duddy's relationships, his family, Montreal's class structure, and Jewish identity all at once, which leaves no room for depth.

A third problem is the thesis that contradicts the body of the essay. Students often discover their real argument while writing, so the introduction promises one idea and the conclusion delivers another. Rather than penalizing this heavily, encourage revision by asking students to reread the final paragraph and rewrite the thesis to match what they actually argued. This turns a structural flaw into a lesson about the writing process.

Using thesis workshops before drafting

Many teachers find that a short thesis workshop before drafting prevents later frustration. Have students submit a single-sentence claim about Duddy, share three or four anonymously with the class, and discuss which are arguable and why. The conversation sharpens everyone's thinking, and students begin to apply the same criteria to their own writing without being prompted.

Pair this with quick written feedback on every thesis, since a short note at this stage costs far less time than rewriting comments across an entire flawed essay. Rubric-based tools can help here by flagging non-arguable claims instantly, leaving the teacher free to discuss deeper issues like originality and nuance. Catching thesis problems early often raises the quality of the whole class set.

Tracking thesis growth over time

If students write several essays during the year, track how their theses evolve. A student who began with broad statements about Duddy's character and now writes focused claims about Richler's use of irony has demonstrated real growth, and pointing that out is motivating. Keeping a simple log of thesis quality across assignments makes progress visible.

Share these observations with students during conferences. Showing a student their first thesis next to their latest gives concrete proof that effort pays off, which is especially valuable for reluctant writers. It also gives you data about which instructional moves worked, helping you refine how you teach argument in later units on other novels.
