Capstone topic + audience choice — Schmoker's argument-soul

Objectives
  • Students choose a capstone topic where they have a real position (Schmoker).
  • Students choose a primary audience (academic / civic / creative) with rationale.
  • Students write a 1-paragraph capstone proposal (topic + audience + working thesis + 3 likely sources).
Vocabulary

Lesson plan

Warm-up

5 min

Quick-share: of your 3 brainstormed topics from yesterday's homework, which one do you actually CARE about? Where do you have a real position?

Teacher moves
  • Affirm: a capstone topic should be one where you have a stance — not a neutral report
  • Connect: today's choice anchors the next 12 weeks

Direct instruction

Today you choose your capstone TOPIC and AUDIENCE. Schmoker's premise: argument is the soul of education. The capstone is not a neutral report — it's a sustained ARGUMENT-WITH-EVIDENCE at minimum, optionally with audience-specific advocacy. So your topic must be one where you have a real POSITION. If you can't state your position in one sentence, the topic is too thin (or too broad). After topic, choose audience. Three audiences (MG-2). ACADEMIC if your topic best serves teachers and scholars; CIVIC if it best serves community decision-making; CREATIVE if it best serves personal-narrative-meets-research. Many topics fit more than one — pick the one that energizes you. Today you write a 1-paragraph PROPOSAL: topic + audience + working thesis + 3 likely sources. The proposal is your contract with yourself. The working thesis can evolve through research, but the topic should not change after this lesson — that's our common rule. We have 16 more lessons; we need a fixed target.

Key examples
  • Specificity wins. 'Topic: sleep' would be too broad; 'Topic: school start times' is researchable.
    model Topic is focused and timely. Audience is named (civic) — the work will be addressed to a real decision-making body. Working thesis takes a position (should shift to 8:30). Sources span types (medical, governmental, primary/interview, peer-reviewed).
    prompt Sample proposal: 'Topic: school start times. Audience: civic (school board + parents). Working thesis: Our district should shift high school start times to 8:30 AM based on adolescent sleep research and academic outcome data. Likely sources: AAP 2014 statement; CDC adolescent sleep brief; local school-board minutes; a peer-reviewed study; an interview with a principal.' What makes this a strong proposal?
  • If your thesis sentence can apply to 1000 essays, it's not a thesis. Make it a position only you would write.
    model Topic too broad. Working thesis is a TOPIC, not a CLAIM. 'Affects' is not a stance — does it harm? Help? Both? Audience choice is fine but uninspired given the broad topic. This needs sharpening.
    prompt Sample weak proposal: 'Topic: social media. Audience: academic. Working thesis: Social media affects teenagers.' What's wrong?
Checks for understanding
  • Turn and Talk: share your top topic choice and your audience choice. Why?
  • Cold Call: name one feature of a strong working thesis.

Teacher notes

Topic-choice is consequential — students live with this topic for 12 weeks. Push for specificity and stance; redirect students whose topics are too broad or who lack a real position. Some students will be stuck — coach them to start with what made them angry, curious, or moved this year. The peer-question protocol surfaces weaknesses early. Save proposals for week 9 check-in — students often want to change topics by week 6; honor that rarely (only if a major flaw emerged), or coach them through the sticky middle.
