Materials & Prep
Project or copy the teacher-created editorial below, one Evidence Audit handout per student, and prepare three display cards: Relevant and sufficient, Relevant but insufficient, Not relevant. Arrange students in pairs, not debate teams. Evidence Audit columns: claim/reason; evidence quoted or paraphrased; relevant? why?; sufficient? what is missing?
Opening
0–6 minDisplay“Should Riverside Middle begin at 8:45 instead of 8:00?” Post these two possible supports without identifying a side: A. “In a survey of 32 Riverside students, 27 said they would like more sleep.” B. “The American Academy of Sleep Medicine recommends 8–10 hours of sleep for teens.”
Ask“Which statement would better support a claim that a later start time would improve student learning, and what important information would still be missing?” Students silently hold up one finger for A, two for B, or three for both, then write one reason. Do not solicit arguments about the policy; say that today’s question is whether a writer has earned a conclusion.
ConfrontReveal that both statements may be relevant, but neither alone proves that Riverside students would learn more. Wanting something is not evidence of its effect, and a general recommendation does not show what will happen at this school. Students revise their initial choice in a different color if needed.
Direct instruction
6–16 minIntroduceAn argument has a claim, reasons that explain why the claim should be accepted, and evidence used to support those reasons. Relevant evidence connects directly to the claim or reason. Sufficient evidence is enough in quality, amount, and variety to justify the conclusion. Think of evidence as the legs of a stool: one strong leg helps, but it cannot safely hold the conclusion by itself.
Project
“Riverside Middle should start at 8:45 a.m. next year. First, students need enough sleep to learn well. The American Academy of Sleep Medicine recommends that teenagers get 8–10 hours of sleep each night. In addition, a 2023 study of 200 students at one nearby middle school found that students who reported at least eight hours of sleep had higher average quiz scores than students who reported less sleep. A later start would also make students happier. In a survey of 32 Riverside students, 27 said they would prefer a later start. Finally, Riverside’s basketball team won the regional championship last spring, showing that our school can make changes successfully. Therefore, the school board should approve an 8:45 start time immediately.”
Think aloud“The claim is an 8:45 start next year. I underline the reason ‘students need enough sleep to learn well.’ The sleep recommendation is relevant because it supports the idea that sleep matters. But it does not tell me that moving Riverside’s start time creates more sleep, or that 8:45 is the right time. The nearby-school study is also relevant, but I notice a common mistake: higher scores and more sleep occurred together; the study does not prove sleep caused the scores. Two sources are not automatically sufficient. I still need evidence about Riverside schedules, transportation, family impact, and whether a later start actually changes sleep or learning here.”
MisconceptionA writer’s confident conclusion, or a fact that sounds impressive, does not make evidence sufficient. The basketball championship is not relevant to whether a new start time improves learning, even if it makes Riverside sound successful.
Check for understandingPoint to the student-preference survey. Students show RS, RI, or NR on paper: relevant and sufficient, relevant but insufficient, or not relevant. Expected: RI. Ask two students to use the frame, “This evidence is because . It is/is not sufficient because .”
Guided practice
16–28 minModelComplete the first row of the projected Evidence Audit with the class for the sleep recommendation. Record: relevant, but insufficient; it is expert guidance but does not establish the proposed change’s likely effect at Riverside.
Have studentsIn pairs, audit the nearby-school study, student-preference survey, and basketball statement. Require a quiet evidence-based exchange: Partner A reads the exact sentence and gives an evaluation; Partner B must paraphrase the evaluation before adding or revising it. No side-taking or rebuttal language.
CirculateListen for students who call the preference survey irrelevant. Clarify that it is relevant to student opinion, but weak for the editorial’s learning claim. Prompt: “Relevant to which reason, exactly?”
ScaffoldProvide the frames: “The writer’s claim is __.” “This evidence supports the reason that __.” “It is relevant/not relevant because __.” “It is insufficient because the writer needs evidence about __.” Students may highlight claim in blue, reasons in green, and evidence in yellow before writing.
ExtensionAsk ready pairs to identify the study’s limitation and distinguish correlation from causation in one precise sentence.
Independent evidence audit
28–40 minWriteStudents independently complete an Evidence Audit for all four pieces of evidence, then write a 5–7 sentence verdict: state the claim, identify one relevant and stronger piece of evidence, identify one irrelevant or weak piece, and judge whether the evidence overall is sufficient. They must include two specific references to the editorial.
ChallengeAdd the single most useful additional piece of evidence the writer should gather and explain why it would strengthen the argument more than another student-opinion survey.
SupportStudents who need an entry point may use the sentence frames and begin with the basketball statement, which has a clear mismatch to the claim. Confer by asking them to match each fact to the reason it is supposed to support.
Closing
40–45 minExit ticketOn an index card, respond in 3–4 sentences: “Is the editorial’s evidence sufficient to justify approving an 8:45 start immediately? Delineate the claim and evaluate two pieces of evidence, including one that is relevant and one that is insufficient or irrelevant.” Collect cards as students leave. Sort for students who can name evidence but cannot explain relevance versus sufficiency; use those cards to form the next lesson’s small group.
