A Toolkit for Productive Conversation

Norms students help author. Sentence stems for the quiet kid. Twelve protocols you can run cold. Six Socratic moves that will hold up any seminar. A "what do I do when…" decision tree for the moments that go sideways. And a parallel canon — because Western philosophy isn't the only philosophy.

Start here

If you have 5 minutes before class

  1. Pick a scenario. Click "For teachers" to read its kit.
  2. Pick a protocol. Most rooms can run Think-Pair-Share or Continuum Line cold.
  3. Open with one of the discussion prompts (not the multiple choice).
  4. Wait at least 8 seconds before clarifying. Trust the silence.
  5. Close with the exit ticket. That's the whole lesson.
Norms — author together

Norms work best when students help draft them. Use the starter set as a draft, then negotiate together. The conversation about WHICH norms to keep is itself the first philosophy lesson.

Starter set — toggle to include

Critique ideas, not people.

We can disagree hard with a position without attacking the person holding it. This is the difference between a debate and a fight.

Steelman the option you didn't pick.

Before defending your view, try to argue the opposite as well as you can. This is the single most underused move in classroom dialogue.

It's okay — and brave — to change your mind.

Changing your mind on the basis of a good argument is intellectual honesty in action. We celebrate it.

It's okay to say 'I don't know' or 'I'm not sure.'

Real philosophy lives in not-knowing. Being uncertain is a sign you're thinking, not failing.

Speak from your own experience, not for others.

"I think…" not "People like me think…" Generalizations shut down dialogue. Specifics open it up.

What's said here stays here. What's learned here leaves.

Confidentiality builds trust. We don't gossip about who said what — but we DO carry the ideas into our lives.

Wait. Then wait some more.

Most discussions go too fast. Eight to twelve seconds of silence after a question gives quieter voices time to enter.

You can step back from the conversation without explaining why.

Some topics hit close to home. Stepping back is always allowed. We won't ask you to justify it.

Build on each other's thinking.

Not every contribution has to be a brand-new point. "Building on what ___ said…" is often the most useful move in the room.

Cite the text or the scenario.

When making a claim about what's in the material, point to it. "At stage 2, the prompt asks…" not "I think they meant…"

One voice at a time.

Cross-talk drowns out everyone. We let one person finish before another begins.

Name discomfort instead of leaving silently.

If something said is making the room hard, you can say so: "I'd like to pause — that landed hard for me." Naming it is courageous and useful.

Better questions are worth more than better answers.

The point of philosophy is to ask sharper questions. Don't rush to a final answer — sit with the question.

Sentence stems — give your students (or kids) a way in

The hardest part of dialogue isn't having an opinion. It's finding a way to say it. These stems are the difference between a discussion and a debate. Categorized by the move they support.

"I notice that…"

Entering the conversation

Begins with observation, not judgment.

"I wonder if…"

Entering the conversation

Surfaces a half-formed thought without committing to it.

"Could it be that…"

Entering the conversation

Tentative; invites others to test the idea.

"What if we asked it this way instead…"

Entering the conversation

Reframes the question without dismissing the previous version.

"Let me try this — I might be wrong…"

Entering the conversation

Permission for half-formed ideas. Models intellectual humility.

"Building on what ___ said…"

Building on each other

Names the prior speaker. Threads the conversation.

"I want to add to that…"

Building on each other

Aligns with a point and extends it.

"Another way of seeing what ___ said is…"

Building on each other

Reframes a peer's idea. Tests whether you understood it.

"That connects to ___ because…"

Building on each other

Links across speakers or scenarios.

"I'd like to push back on…"

Pushing back

Names disagreement directly. Always followed by a reason.

"The strongest objection to that is…"

Pushing back

Steelmans the opposing view. Useful even if you don't hold it.

"But what about a case where…"

Pushing back

Counter-example. The classic Socratic move.

"I disagree because…"

Pushing back

Direct, but pairs with a reason — never just "I disagree."

"I'm changing my mind because…"

Changing your mind

Names the move explicitly. Celebrates revision.

"Earlier I thought ___, but now I think ___"

Changing your mind

Two-part stem that traces the change.

"I'm convinced by what ___ said about…"

Changing your mind

Credits the speaker who moved you.

"I'm still unsure about…"

Changing your mind

Names ongoing uncertainty without faking conclusion.

"So what we're really asking is…"

Finding the shape of the question

Restates the underlying question. Useful when discussion drifts.

"Both views actually agree that…"

Finding the shape of the question

Surfaces hidden common ground.

"The real disagreement is about…"

Finding the shape of the question

Names where the views genuinely diverge.

"The shape of this question is…"

Finding the shape of the question

Steps back to look at the type of problem.

"I don't have an answer, but…"

Asking for help

Permission for partial thinking. Models that you don't need a verdict to contribute.

"Could someone help me think through…"

Asking for help

Direct request. Names what you're stuck on.

"What am I missing?"

Asking for help

Invites correction. Powerful from anyone, especially the teacher.

"Could you say more about…"

Asking for help

Asks for elaboration. Treats the speaker's idea as worth more time.

Five Socratic moves

Memorize these five and you can run a seminar cold. They are not personality traits — they are tools.

Purpose: Make sure everyone (including the speaker) knows what was said.

When: When a contribution is too compressed, ambiguous, or jargon-heavy.

Try saying

  • "Can you say that another way?"
  • "What do you mean by ___?"
  • "Could you give us an example?"
  • "Is this what you're saying — ___?"

Pitfall: Clarify gently. "What do you mean?" can sound dismissive; "Could you say more about that?" usually doesn't.

Purpose: Surface the hidden premises a position depends on.

When: When a speaker treats a controversial premise as obvious, or when consensus is forming too fast.

Try saying

  • "What does that depend on?"
  • "What would have to be true for that to be right?"
  • "Are you assuming ___?"
  • "Where does that come from for you?"

Pitfall: Don't ask leading questions. "You're assuming X, right?" closes thought; "What's behind that view?" opens it.

Purpose: Test a general claim by introducing a case it might fail to handle.

When: When someone makes a strong universal claim ("It's always wrong to ___").

Try saying

  • "What if instead of A, it were B — does your answer change?"
  • "Suppose someone in ___ situation. Does the rule still hold?"
  • "Can you imagine a case where the opposite would be right?"

Pitfall: The counter-example should be GENUINE, not a gotcha. The point is testing the claim, not winning the round.

Purpose: Trace what else has to be true if a position is right.

When: When you want to make the stakes of a position visible.

Try saying

  • "If that's true, what else has to be true?"
  • "What follows from that view?"
  • "What would the world look like if everyone reasoned this way?"
  • "Are you also committed to ___?"

Pitfall: Implications can be unwelcome. Use this move with care, especially when a student has just shared a personal view.

Purpose: Step back from the question to look at the question itself.

When: When discussion is stuck, when students seem to be talking past each other, or as a closing move.

Try saying

  • "Why is this question hard?"
  • "What kind of disagreement is this?"
  • "What would convince you to change your mind?"
  • "What do we actually need to know to settle this?"

Pitfall: Meta moves can feel evasive if used too early. Save them for when there's enough on the table to step back from.

Purpose: Trace where a view comes from — who else holds it, what tradition, what evidence.

When: When you want to connect classroom discussion to a wider conversation.

Try saying

  • "Where does that view come from?"
  • "Whose argument sounds most like yours?"
  • "What evidence would change your mind?"
  • "How would someone from ___ tradition answer this?"

Pitfall: Don't use Source to credential or de-credential a student's view. The point is connecting, not authorizing.

Twelve protocols

Each protocol is a structured way to run a discussion. Filter by what fits your room. Click to expand any protocol for the full step-by-step.

Safety, equity, and what to do when…

Discussions go sideways. That's not failure — it's the work. This decision tree walks you to specific guidance for the moments that matter most.

What do I do when…

What's happening in your discussion right now?

Some practices apply to every discussion, regardless of topic:

  • Everyone has a story you don't know. A scenario about loss may hit a student dealing with a recent death; a scenario about surveillance may hit one whose family is undocumented. Watch faces.
  • Opt-out is always available. Students can step back from any conversation without explaining why. Make this explicit.
  • Confidentiality has limits. What happens in the room stays in the room — UNLESS a student discloses harm to self, abuse, or imminent danger. Then your reporting obligations kick in. Be clear about this in advance.
  • Documentation matters. If something significant happens, write it down within the day. Memory fades.

Wait time. Most teachers wait 1–2 seconds after a question. The research recommendation is 8–12. Try counting silently. The first time you hold the silence, the room shifts.

Tongue-bite practice. When a student gives a partial answer, your instinct is to fill the gap. Resist. Wait three more seconds. Often they'll continue.

Named random call (with warning). Cold-calling without warning can shut students down. Try: "I'm going to come to ___ next — I want to give them a moment to think first." This tells the student they will speak; they have time to compose.

Participation tracking. Use a seating chart with tally marks. The chart makes invisible patterns visible. Most teachers are surprised to see how skewed participation is.

Global Canon

The Philosophical Canon section in the Hub draws primarily on Western traditions — Plato, Aristotle, Dewey, Nozick. Those traditions answered the questions in this bank in particular ways. Other traditions answered them differently, sometimes in ways the Western canon never quite reached. This section names some of them. It is not a survey. It is an invitation.
