Read the fictional club text, choose one of four equally prominent stances, and record a detail and reason before adding a later reflection. The preview checks only whether the required fields are present; it does not grade a stance, infer consensus or overwrite the initial response.
Put the shared text before the choices
Begin with the shared text:
The club has 12 tables. It needs 4 tables for building and 4 tables for drawing. There are 8 participants today.
The discussion statement is:
The club should keep 4 tables available for building at every meeting.
The text describes today's needs and participants. The statement proposes a rule for every meeting. That difference leaves room for several reasoned positions; the activity is not a quiz whose correct answer is Agree.
Columbia Teachers College CPET's description explains four posted opinions and participant self-selection. This activity uses the same self-selection structure with the fictional club question.
Make all four signs equally readable
The four buttons are Strongly agree, Agree, Disagree, and Strongly disagree. For a room activity, you can make matching signs yourself. Keep them equally prominent so their presentation does not suggest a preferred answer.
Display the full text card and statement before learners select a position. Explain that students may choose a sign, indicate a choice while seated, or record it privately on the slip. Passing a public explanation does not eliminate the written participation route.
Use fictional club logistics rather than asking learners to disclose personal experiences or vote on rights, accommodations or actual school policy. The teacher sets discussion boundaries and reviews actual access/support needs before the activity.
Ask for a detail and the inference it supports
Use the initial stance, cited detail, and reason fields first. After recording that response, use the reflection and what-changed fields to explain your later thinking. A cited number is not a reason until the writer explains its connection to the statement.
An illustrative Agree response could cite the need for four building tables and argue that keeping them available protects that planned activity. An illustrative Disagree response could use “today” and argue that this information does not justify the same allocation at every future meeting.
Both can refer accurately to the shared text. Neither proves what the club should actually do. The eight participants do not establish how they divide between activities or how many sit at each table; do not invent those details to decide the debate.
The teacher reviews evidence accuracy and the reasoning link, not whether the stance matches a preferred corner.
Retain the first response when a learner reconsiders
An original demonstration slip starts Agree, citing four building tables. After hearing the future-meetings question, its reflection becomes “Unsure: today's need may not be the same at each meeting.” Keep that reflection and the initial Agree response together.
Unsure belongs in the reflection text; it is not secretly converted to Disagree or added as a fifth physical sign. A blank reflection, a passed public explanation and a stated uncertainty are separate records, not errors to fill automatically.
The demonstration is teacher-prepared example wording, not an actual learner result. Leave real responses and observations blank until supplied. Changing a stance alone does not establish learning gain, and retaining a stance can still involve a better explanation.
Use the practice slip
Select a stance, cite a detail and explain its connection, then Record initial response. The resulting initial snapshot stays fixed while the after-discussion field changes. Preview reflection shows both records and what changed. Reset clears all practice entries; the source card and four signs remain.
Learners can complete the same evidence-and-reason steps while seated or on paper. Review the evidence link rather than agreement. A teacher can compare accurate but differently reasoned responses without deciding that one corner represents stronger ability.
Copy a prompt for this example
Create a single self-contained HTML Four Corners discussion slip with embedded CSS and JavaScript. Show the shared text and statement before four equally prominent stance buttons. Provide labeled fields for a cited detail, reason, later reflection, and what changed.
Use this fictional text: “The club has 12 tables. It needs 4 tables for building and 4 tables for drawing. There are 8 participants today.” The statement is: “The club should keep 4 tables available for building at every meeting.”
Offer Strongly agree, Agree, Disagree, and Strongly disagree. Do not label one stance correct. Require a selected stance, detail, and reason before Record initial response. Store an independent snapshot and display it separately.
Once recorded, the initial snapshot must remain unchanged even if the draft stance or text fields change. A second recording request should explain that the initial response is already retained. Let the learner add a reflection and what changed, then choose Preview reflection to see both stages together. Require those fields without grading their meaning.
Allow Unsure in reflection text without adding a fifth physical corner or forcing it into Disagree. Include a separate illustrative example that begins Agree and later questions whether today's needs apply to every meeting. Keep it separate from the learner's entries.
Reset clears practice responses and hides the example while preserving the text and stance choices. Mention seated or paper participation and the option to pass on public explanation. Return only the complete HTML file.
For the next discussion opening, NOS can display this prepared HTML text and slip. Read the “today” versus “every meeting” contrast aloud, offer the seated response route, and preserve each learner’s actual reflection in the maintained classroom materials.
