What Is elenchus.talk?

ἔλεγχος (elenchus): Greek term for Socratic cross-examination.

elenchus.talk: Platform for Socratic classroom engagement.

Not “getting students to talk.” Not “class discussion.”

Cross-examination in service of truth.


How It Works

For Students (Track 2)

  1. Sign up for sessions - Choose which class meetings to attend and prepare for
  2. Prepare beforehand - Read materials knowing you might be called on
  3. Get called on randomly - Instructor questions you (Socratic dialogue)
  4. Experience aporia - Productive confusion when you realize gaps in understanding
  5. No grades - Sessions track preparation and attendance, not performance

For the Class

While one student is questioned:

  • Self-assess: Would I have answered differently?
  • Take notes: What contradictions emerged?
  • Learn: Real understanding comes from watching someone think through confusion

Not Cold-Calling. Warm Calling.

Traditional cold-calling:

  • Surprise students → anxiety → shallow participation

elenchus.talk approach:

  • Students choose to sign up (agency)
  • Students prepare knowing they might be called (responsibility)
  • Instructor questions deeply when students are ready (elenchus)
  • Goal is productive confusion not right answers

Core Features

Student Agency

  • Choose which sessions to attend
  • Set your own “notice window” (how much advance warning you need)
  • Full control over participation level

Fair Distribution

  • Students who haven’t been called get priority
  • Waitlist system ensures everyone gets opportunities
  • No gamification - just equitable access

Formative, Not Summative

  • Track preparation and participation
  • No grades or points
  • “Prepared” vs “needs more preparation” (descriptive, not evaluative)

What Happens in a Session

Typical flow:

  1. Setup: 20 students sign up for Tuesday’s session (capacity: 15), 5 join waitlist
  2. Preparation: Students prepare readings knowing they might be called
  3. Session begins: Instructor randomly calls on signed-up students
  4. Questioning: “Why do you think that?” “What would happen if…?” “How does that contradict what you said earlier?”
  5. Aporia: Student realizes gap in understanding
  6. Class learns: Everyone observes, self-assesses, takes notes
  7. Real learning: Through questioning, not information transfer

Why “elenchus”?

The name signals serious Socratic method.

Learning what “elenchus” means mirrors the pedagogy itself:

  • You don’t know → you investigate → you learn
  • Aporia (productive confusion) is the point

What It’s NOT

  • ❌ Attendance tracking (it’s about depth, not presence)
  • ❌ Participation points (it’s formative, not summative)
  • ❌ Discussion facilitation (it’s cross-examination)
  • ❌ EdTech gamification (no badges, points, or streaks)

What It IS

  • ✅ Infrastructure for Socratic inquiry at scale
  • ✅ Tool to prepare students for deep questioning
  • ✅ Fair system for distributing calling opportunities
  • ✅ Embodiment of student agency and anti-banking-model pedagogy

Questions?

“What if I’m not prepared one week?”

  • Don’t sign up for that session. No penalty.

“What if I freeze up when called on?”

  • That’s okay. Aporia is the goal. Instructor will guide you through.

“How often should I sign up?”

  • Recommend 2-3 sessions per month minimum for Track 2.

“Can I watch without signing up?”

  • Yes. Come to class, observe, learn. Sign up when ready.
