Lead and join evidence-based discussions, integrate sources in diverse media, and evaluate a speaker's reasoning and evidence

Learning goal: Initiate and participate effectively in a range of collaborative discussions (one-on-one, in groups and teacher-led) with diverse partners on grades 9-10 topics, texts and issues, building on others' ideas and expressing your own clearly and persuasively. Come prepared, draw explicitly on evidence; work with peers to set rules for collegial discussion and decision-making, goals, deadlines and roles; propel conversations with questions that connect to broader themes, incorporate others, and clarify, verify or challenge ideas; respond thoughtfully to diverse perspectives, summarize agreement and disagreement, and qualify or justify your views in light of evidence. Integrate multiple sources presented in diverse media or formats, evaluating the credibility and accuracy of each. Evaluate a speaker's perspective, reasoning, and use of evidence and rhetoric, identifying fallacious reasoning and exaggerated or distorted evidence.

The scenario this unit uses. Linden Ridge High School is invented, and so is every number attached to it. The school, which enrolls 1,140 students, is deciding whether to require students to lock their phones in magnetic pouches during class periods, unlocking them at lunch and at the end of the day. The simulated sources are these. Cost sheet: 1,140 pouches at 25 dollars each (28,500 dollars) plus six unlocking stations at 450 dollars each (2,700 dollars), a total of 31,200 dollars, to be paid from a one-time fund of 35,000 dollars. Pilot log: two ninth-grade English sections, 58 students in all, used pouches for six weeks; their two teachers counted phone-related redirections and recorded an average of 9 per 50-minute period in the three weeks before the pilot and 2 per period during it. Pilot quizzes: unit-quiz averages were 74 percent before the pilot and 79 percent during it, on different units. Student survey: 640 of the 1,140 students responded; 384 opposed the policy, 192 supported it and 64 were unsure. Parent letter: 41 families signed a letter asking how they would reach their children in an emergency. Oakmere report: a neighboring district, also invented, replaced 90 of its 750 pouches in the first year because of damage or loss. None of this describes a real school, and the evidence supports more than one reasonable position.

What a collaborative discussion is for. A discussion is a group reasoning together toward a better-supported understanding than any member started with. It is not a debate someone wins. The standard asks you to initiate discussions (start them, not only join them) and to take part in a range: one-on-one with a partner, a small group, and teacher-led whole-class talk, with diverse partners whose experiences and views differ from yours. Building on others' ideas and expressing your own clearly and persuasively are both required; a student who only agrees, or only argues, has done half the work.

Come prepared and use the preparation explicitly. Preparation means having read and researched the material under study before the discussion. At grades 9-10, preparation is visible: you refer to evidence from texts and other research by name and location. "I think most students hate it" gives the group nothing to test. "The survey says 384 of 640 respondents oppose it, but that is respondents, not the school" gives the group a fact and its limit, and stimulates a thoughtful, well-reasoned exchange.

Set rules, goals, deadlines and roles with peers. Collegial discussion needs agreed norms: one speaker at a time, paraphrase before challenging, criticize ideas and not people. It also needs a decision-making rule chosen in advance. The standard gives three examples: informal consensus (the group continues until everyone can accept a position, even if it is not their first choice), taking votes on key issues (majority decides, useful under a deadline), and presentation of alternate views (the group reports its main position and a minority view with its reasons). A clear goal and deadline ("recommend a position to the board, with its best evidence and one open question, in 20 minutes") keep talk from drifting. Roles, as needed, might include a facilitator who manages turns and time, an evidence-checker who verifies figures against the sources, and a recorder.

Propel the conversation. Three moves keep a discussion moving forward. First, pose and respond to questions that relate the current discussion to broader themes or larger ideas: "Is this really about phones, or about when a community may limit individual freedom for a shared benefit?" Second, actively incorporate others: invite a quiet member by name with a specific question, not "Anyone else?" Third, clarify, verify or challenge: ask what someone means ("By 'it works', do you mean fewer interruptions or better grades?"), check a figure against the source, or challenge a conclusion with evidence.

Respond to diverse perspectives; summarize; qualify or justify. Respond thoughtfully means restating another view fairly before answering it. Periodically someone should summarize points of agreement and disagreement so the group knows where it stands. When evidence or reasoning warrants, you qualify your view (narrow it: "I still support pouches, but only during class, not lunch") or justify it (explain why new evidence does not change it). You may also make new connections: link two points no one had joined.

Original discussion transcript (four students, 20-minute goal).

Amara (facilitator): Our goal is a recommendation with its best evidence and one open question, and we have 20 minutes. We agreed to vote if we have no consensus by minute 15. Ben, you're checking evidence. Start us off?

Ben: The pilot log went from 9 redirections a period to 2. That's the biggest number we have.

Chloe: But the survey says 60 percent of students are against it.

Ben (checking): 60 percent of the 640 who answered. That's 384 students, about a third of the school. We don't know what the other 500 think.

Amara: So both numbers need a limit. Diego, you've read the families' letter. What did it actually ask for?

Diego: It didn't say no pouches. It asked how parents would reach kids in an emergency. Forty-one families signed.

Chloe: That changes it for me. I was against it, but if the problem is contact, a protocol could solve that. I'd support it only if the protocol is published before the board votes.

Amara: Let me summarize. We agree the pilot shows a drop but is small. We agree the survey shows real opposition from respondents. We disagree on whether opposition should decide it. Can I ask a bigger question: when should a school limit something students own for a shared benefit?

Ben: When there's evidence of the benefit and the cost to students is small. Lunch access would make the cost smaller.

At minute 15 the group had no consensus: three members supported a class-period policy with the protocol published before the first day of school, while Chloe held that it must be published before the board votes. They took the vote they had agreed on and recorded the recommendation, Chloe's alternate view with her reason, and the open question: whether the drop would hold beyond two classes.

Reading the transcript. Amara sets the goal, deadline, decision rule and a role. Ben verifies a figure and qualifies Chloe's claim. Amara incorporates Diego with a specific question. Chloe qualifies her view in light of new evidence and makes a new connection (contact problem, protocol solution). Amara summarizes agreement and disagreement and relates the discussion to a broader theme.

Integrate sources in diverse media and evaluate each. Information reaches you visually (charts, photographs, video), quantitatively (tables, statistics) and orally (interviews, speeches, podcasts). Integrating means combining them into one understanding, noting where they agree or conflict. Evaluating credibility asks whether the source deserves trust (who made it, their expertise and motive); evaluating accuracy asks whether its content is correct and not misleading. Suppose a group has three sources. (1) A bar chart of the pilot counts made by the pilot teachers. Credibility: moderate, since they volunteered; accuracy: check the axis and the numbers against the log. (2) A recorded audio interview in which a pilot teacher describes the counting rule and the counts. Credibility: first-hand; accuracy: consistent with the log's written rule and figures. (3) A manufacturer's video claiming "up to 90 percent fewer distractions." Credibility: low, a sales motive; accuracy: unverifiable, no method. Integrated: the chart and interview agree on what was counted and found; the video adds no reliable information.

Evaluate a speaker. To evaluate a speaker, judge four things. Perspective: the speaker's position and interests, which shape what they emphasize. Reasoning: whether conclusions follow from reasons. Evidence: whether it is relevant, sufficient and accurately reported. Rhetoric: the choices of language and delivery meant to persuade, such as repetition, rhetorical questions and emotional appeals, which are legitimate when they serve true claims and manipulative when they replace evidence. Watch for fallacious reasoning and for evidence that is exaggerated (stated as bigger than it is) or distorted (presented so that it misleads, such as a graph whose axis is cut off).

Original speech excerpt — spoken at a simulated board meeting by a parent who sells classroom technology.

"Our children are drowning. Every single teacher in the pilot saw distractions collapse, falling by 350 percent. Look at this chart: the bar before the pouches towers over the bar after. Do we want focused classrooms, or do we want chaos? Either we act tonight, or we fail a generation. And I ask the people who oppose this: what are you afraid of?"

[The chart the speaker displays has a vertical axis that begins at 1.5 redirections, not at zero.]

Evaluation. Perspective: the speaker sells classroom technology, an interest the audience should know, though it does not by itself make the claims false. Evidence: "every single teacher in the pilot" misleads in two ways: it makes two teachers sound like many, and it asserts that each teacher saw a drop, which the log, an average across both sections, does not show (a listener would need each teacher's own counts before accepting it); "falling by 350 percent" is distorted, since a count such as redirections cannot go below zero and so cannot fall by more than 100 percent. The actual drop from 9 to 2 is 7, and 7 divided by 9 is about 78 percent. The chart "towers" because its vertical axis starts at 1.5 rather than zero, so a difference of 7 looks like near-total disappearance. Reasoning: "Do we want focused classrooms, or do we want chaos?" and "Either we act tonight, or we fail a generation" are false dilemmas. "What are you afraid of?" questions opponents' motives instead of their reasons. Rhetoric: "drowning" and "collapse" are emotional appeals standing in for the pilot's limits, which the speaker never mentions.

Worked verification in discussion: Claim made in a group: "Sixty percent of the school is against pouches." Verify: the survey reports 384 of 640 respondents. 384 divided by 640 is 0.60 of respondents; 384 divided by 1,140 is about 0.34 of the school. Clarifying response: "That's 60 percent of the people who answered. The 384 who oppose are about a third of the whole school, and we don't know about the other 500." The verification changes what the group can conclude, which is why an evidence-checker role is worth assigning.

Worked decision-making rules: The same group, three ways. Informal consensus: they keep talking until all four can accept "class-period pouches after a published protocol," even though Chloe would prefer the protocol before the vote. Vote: at the deadline, 3 of 4 support the recommendation, and it passes. Presentation of alternate views: the report gives the majority recommendation and Chloe's view that no decision should come before the protocol is published, with her reason. Each is legitimate; the group must choose which it is using before the discussion, not after.

Worked percentage-change check: From 9 to 2 is a decrease of 7. Percent decrease is the decrease divided by the starting amount: 7 divided by 9 is about 0.78, or 78 percent. A decrease of 100 percent would mean the count reached zero; because a count of redirections cannot go below zero, its decrease cannot exceed 100 percent. (Quantities that can become negative, such as a bank balance, are different.) The speaker's "350 percent" appears to come from comparing 9 with 2 incorrectly (9 is 4.5 times 2, or 350 percent more than 2), which describes the before count relative to the after count, not the drop.

Worked integration of media: Chart (visual and quantitative): 9 before, 2 after, axis from zero, made by pilot teachers. Interview (oral): a pilot teacher explains the counting rule, reports the same before and after counts, and admits some cases were judgment calls. Integrated statement: "The pilot teachers' chart and interview agree that redirections fell from about 9 to about 2 per period; the teacher's admission that some cases required judgment is a reason to have future counts made by staff outside the pilot." The integration uses each source for what it does best and carries forward the limit one of them revealed.

Discussion record (three settings): The standard asks for a range of discussions, so practice in each. One-on-one: with a partner, take 5 minutes each to initiate the discussion with a question from your preparation, build on your partner's answer and summarize where you agree. Teacher-led: in a whole-class discussion, make at least two contributions, one that builds on a classmate's idea by name and one that brings in evidence; the teacher gives each student feedback on initiating and building. Group: in a group of four, run a 20-minute discussion on a grades 9-10 issue or text your class is studying. Before starting, write your rules, decision-making method, goal, deadline and roles. During the discussion, the recorder tallies each move: evidence cited with location, question linking to a broader theme, invitation to a quiet member, clarification, verification, challenge, summary, qualification or justification. After, each member writes which move they used least and one sentence they could have said, and how their participation changed between the partner, group and whole-class settings.

Independent performance: Watch or read a persuasive speech (the teacher supplies a recorded public speech or a written one), and collect one additional source in a different medium on the same topic. Write a 600-word evaluation. Success criteria: the speaker's perspective identified with how it shapes the speech; the central claim and main reasons laid out, with reasoning judged; each piece of evidence checked for relevance, sufficiency and accuracy, with any exaggerated or distorted evidence explained; at least two rhetorical devices identified and judged as serving or replacing evidence; any fallacies named with the reason; and the additional source integrated, with its credibility and accuracy evaluated and its agreement or conflict with the speech stated.
