The Gate
The gate is the decision point after each Feynman tutor session. It determines whether the learner advances, remediates, or completes the series.
The Feynman tutor session
After listening to an episode, the learner opens a conversation with Lugh. The tutor’s job is to test understanding against the episode’s stated learning objectives.
The session follows a protocol:
- Explain — “Explain [concept] to me like I’m new to this.” Open-ended, no hints.
- Probe — The tutor asks about edge cases, connections, or implications the learner didn’t mention. “What happens if the bucket is already half full?”
- Compress — “Can you give me that in one sentence?” Tests whether the learner has internalized the concept vs. memorized a sequence of facts.
- Transfer — “How would this apply to [different context]?” Tests whether the understanding is flexible.
Not every learning objective gets all four steps. The tutor adapts based on confidence — if the explanation in step 1 is thorough and accurate, it might skip to transfer.
Assessment output
Each learning objective gets categorized:
- Solid — explained accurately, handles edge cases, can transfer
- Shaky — partial understanding, gaps in reasoning, or residual misconceptions
- Missed — couldn’t explain or explained incorrectly
The decision
0-1 shaky, 0 missed → Advance
The system recommends advancing to the next episode. Any shaky concepts get a brief note: “You might want to revisit the bucket model — Episode 3 builds on it.”
The next episode’s script will subtly reinforce the shaky concept without making it the focus.
2+ shaky or 1+ missed → Remediate (recommended)
The system recommends a remediation episode. This is NOT the same episode again. It’s a new, shorter episode that:
- Approaches the missed/shaky concepts from a different angle
- Uses different analogies and examples
- Focuses only on the gaps, not the full topic
- May use the learner’s own words from the tutor session to build bridges
After the remediation episode, the learner goes through another tutor session covering only the remediated concepts.
Learner override
The gate recommends but doesn’t block. The learner can always choose to:
- Advance anyway, with the system noting which concepts to watch for
- Remediate even when the system says they’re ready (if something feels shaky to them)
- Re-listen to the original episode instead of getting a remediation episode
Respecting learner autonomy is a core principle. The system provides signal, not authority.
Series completion
When the learner passes the final episode’s gate, the system generates:
- A completion summary with the full learning arc
- A condensed reference document covering all key concepts
- An optional “graduation” tutor session covering cross-episode connections
This completion package is also a potential shareable artifact.
