Editorial on School Start Times: Weighing Evidence and Repairing a False Dilemma
An eleventh-grade ELA class is evaluating a student editorial that argues the district should move high school start times from 7:25 a.m. to 8:30 a.m. The editorial cites two pieces of evidence: a district survey in which 62% of 410 respondents said they are 'often tired in first period,' and a sleep-science review concluding that adolescents need 8–9 hours of sleep per night. It closes with the sentence 'Either we change start times or we accept that our students will fail.' A letter from the transportation director responds that buses run three tiers, so a later high school start would push the elementary start to 9:10 a.m., and notes that the survey's response rate was 18%. The class must decide which claims the editorial supports well, which it does not, and how to revise the argument without weakening its case.
1. Rank the three pieces of evidence by how well each supports the editorial's conclusion. Identify the strongest and weakest support and state precisely what each source can and cannot establish.

The conclusion - a later start would reduce student sleep loss - requires three links: local students are sleep-deprived, start time contributes to that, and a later start is workable.
- Sleep review: strongest single support for the causal link. It is synthesized research, so it establishes the mechanism (adolescent circadian delay plus early starts shortens sleep). It cannot show this district is affected and says nothing about 7:25 specifically.
- District survey: relevant but fragile. Local self-report is the right kind of evidence for local prevalence, but an 18% response rate means 410 respondents represent roughly 2,280 invited students. Students who feel tired are more likely to respond, so 62% probably overstates the share. 'Often tired' also is not a sleep-duration measure.
- Transportation letter: not disconfirming. It challenges feasibility, not the fatigue claim. It should reshape the recommendation, not the evidence about sleep.
So the editorial is best supported on the general mechanism and weakest where it implies the survey proves a district-wide crisis.
2. The final sentence is an either/or claim. Explain why it is logically flawed, then rewrite it so the editorial keeps its urgency without overclaiming.

The sentence is a false dilemma: it presents two options and hides at least a third. Changing start times is not the only way to reduce sleep loss, and keeping 7:25 does not guarantee failure. Alternatives include restructuring the three bus tiers, shifting elementary and high school starts in opposite directions, capping after-school commitments, or phasing in a later start over two years. Because the audience includes a transportation director who has a real constraint, the either/or framing invites rejection rather than negotiation.
A revision that preserves the stakes: 'If we keep a 7:25 start, we should expect chronic sleep loss for a large share of our students; changing the schedule is the most direct lever we have, and it will require solving the bus-tier problem rather than ignoring it.'
The trade-off is honest: the revision concedes complexity and loses some rhetorical heat, but it survives the transportation director's objection and keeps the claim tied to evidence.
3. What single piece of additional evidence would most reduce the transportation director's objection, and why would it be more useful than another student survey?
Read the worked answer
A costing and routing study of the three-tier system: how many buses and drivers would be needed, what the per-year cost is, and whether flipping elementary and high school tiers keeps elementary students from waiting in the dark. That evidence attacks the actual constraint - feasibility - instead of re-measuring student fatigue, which is already reasonably established.
It is more useful than another survey for two reasons. First, the objection is logistical, so data about sleep cannot answer it; the argument stalls until the feasibility question is addressed. Second, a routing study produces numbers the board can vote on (cost per year, number of routes, earliest elementary pickup time), whereas another self-report survey adds a second soft estimate of the same variable and inherits the same nonresponse problem. A comparable district's pilot results would be a reasonable second choice, but direct local routing data is stronger because it reflects this district's geography and contracts.
