Two Texts on Later Start Times
Ms. Okafor’s class is comparing two texts about later school start times. Text A, a one-page district newsletter, explains that the middle school moved its start time from 7:45 to 8:20 a.m. It reports that tardiness office visits dropped 18 percent and that 68 percent of students still get less than eight hours of sleep. Text B is a two-paragraph letter to the editor from a parent who is also a pediatric nurse. She describes her son falling asleep at breakfast and writes, “Every family I know wants the later start.” The class must write a paragraph explaining which text gives stronger evidence for the claim that later starts improve student health, and why. Priya says, “Text B is stronger because a nurse wrote it, and Text A is just numbers.” Ms. Okafor has one class period and a three-column organizer labeled Claim, Evidence, Source.
1. Evaluate Priya’s reasoning. Which part is sound, and which part breaks down?

Sound part. Checking who wrote a text is exactly right. Authorship and expertise affect how much weight a claim deserves, and Priya is doing that.
Where it breaks down. Three problems. First, a nurse writing a letter to the editor is offering an anecdote and an opinion, not reporting a study; the credential does not make the letter evidence. Second, the credential is general - pediatric nursing - but the letter makes a claim about an entire community, supported by “every family I know,” which is an overgeneralization from a small, self-selected group. Third, dismissing Text A as “just numbers” confuses format with quality: numbers can be weak or strong, but their being numbers is not the flaw.
Better framing for Priya. Ask not “Who sounds more convincing?” but “What kind of evidence is this, and does it support this specific claim?” Text B illustrates a problem; Text A measures patterns. Neither automatically wins.
2. What should a strong paragraph conclude about which text better supports the health claim, and how should it handle the fact that Text A’s data measures attendance and sleep hours rather than health directly?

A defensible conclusion. Text A provides stronger support, but only partial support. It reports a before-and-after change in tardiness and a sleep-duration figure, both of which are relevant to health because sleep duration is a health-related measure. Text B describes one family’s experience and a broad assertion; it illustrates but does not establish a pattern.
Handling the gap honestly. The paragraph should state the limitation: Text A does not show that the later start caused better sleep, and it does not report health outcomes such as illness or stress. The 68 percent figure actually complicates the claim, since most students still sleep less than eight hours.
Model sentence. “Text A gives stronger evidence because it reports measured sleep and attendance data, but it does not prove the later start caused better health; Text B offers an example, not evidence, and its claim about ‘every family’ goes beyond what one parent can know.”
Why this beats “Text A wins.” It rewards the reasoning the standard asks for: evaluating evidence and its limits.
3. How do the structures of the two texts signal their different purposes, and what should students notice about each?
Read the worked answer
Text A: explanatory and report-like. It opens with a dated change, then presents outcomes in sequence, then a remaining concern. The structure is problem–change–result–caveat. The caveat (68 percent still short on sleep) is a signal that the purpose is to inform, not to persuade; a purely persuasive newsletter would likely omit it.
Text B: persuasive and personal. It opens with a scene (a child asleep at breakfast), moves to a general claim, and closes with a call on the reader. Scene-then-claim is a persuasive structure: the anecdote creates sympathy, and the generalization tries to convert sympathy into public opinion.
What students should do with this. Match structure to purpose, then ask whether the structure is doing honest work. The newsletter’s caveat strengthens its credibility; the letter’s leap from one son to “every family” weakens its.
Quick organizer entry. Text A - purpose: inform; structure: report with limitation; effect: credible but incomplete. Text B - purpose: persuade; structure: anecdote plus generalization; effect: vivid but unsupported.
