The Six-Minute Presentation and the 2014 Statistic
Four students have six minutes to present "How Sleep Affects Teen Learning" to their class, with four slides and a rubric requiring that (a) every member speaks, (b) one visual does more than decorate, and (c) claims are sourced. During rehearsal, Devon proposes putting a full 90-word paragraph on slide three and reading it aloud, "so we don't forget anything." Amara wants to open with the line "Teens who use phones after 10 p.m. lose 90 minutes of sleep," taken from a 2014 article she has not opened; she found the sentence in a summary blog. In the run-through, the group hits the six-minute mark during the third speaker, and a classmate's practice question - "Where does the 90 minutes come from?" - goes unanswered.
1. Evaluate Devon's slide-and-read plan against the rubric, and propose a specific alternative for slide three.

The plan fails two rubric items at once. Reading a 90-word paragraph aloud takes roughly 35–40 seconds of a 360-second budget and delivers nothing a listener could not have read faster; worse, it splits the audience's attention between voice and text, so neither lands. And it cannot satisfy criterion (b): a slide that just holds the script is decoration.
A replacement for slide three: one graph plotting reported sleep hours against self-reported test scores, with two labels ("under 7 hours" / "8+ hours") and a one-line takeaway as the title - "More sleep, higher scores - same students, same school." Devon speaks the paragraph instead, from cue cards with three keywords, and the graph stays on screen while he talks. The audience then reads a shape and hears an explanation, which is what the rubric means by a visual doing work.
The general rule: if the slide can be read aloud word for word, it is a script; if the speaker must explain it, it is a visual.
2. Amara's opening statistic is unsourced and possibly wrong. Describe what the group should do, given that they present tomorrow and time is short.

Three moves, in order.
- Verify or drop, not hedge. Amara has a sentence from a blog summarizing an unopened 2014 article. "90 minutes" is a suspiciously round number and the claim is a decade old. If they cannot open the original and confirm the population and method in the next hour, they drop it. A flashy number that collapses under one question costs more than it buys.
- Replace it with something the group can defend. They already have material: reported sleep hours and test scores. Even "students who report under seven hours of sleep also report lower test scores" is a weaker but honest opener, and it is sourced.
- Rehearse the answer to the question they already failed. "Here is the study, here is who it followed, here is what it cannot tell us" - that answer models the rubric's sourcing criterion instead of merely satisfying it.
The judgement being tested: the value of a statistic is not its vividness but whether the presenter can trace it. If you cannot trace it, you do not get to open with it.
3. During the presentation, a classmate asks, "So are you saying phones are the problem?" Write the response the group should give, and explain the listening and speaking choices inside it.

"Partly - but not in the way the question suggests. What we can say is that students in our survey who used screens after 10 p.m. reported sleeping less. What we can't say is that phones caused it; students with more homework may use phones later and sleep less. So we'd frame it as a risk factor, not a cause."
Choices inside that answer:
- It repeats the question's frame before correcting it ("partly - but not in the way..."), which signals listening rather than deflection.
- It separates what the group can say from what it cannot. This is the rubric's sourcing criterion performed live, and it is more persuasive than a confident yes.
- It names a rival explanation (homework) instead of defending the claim, which shows the group has thought beyond its own conclusion.
- It stays short - about 25 seconds - so the presentation does not lose time to the Q&A.
What the group must avoid is the two common failures: agreeing with a claim they never made, and dismissing the questioner. Neither is listening; both are performance.
