Participant studies
Run a learning and tutoring experiment
Compare solo, Council, human, human–AI, scripted-feedback, and no-tutor conditions using immediate, transfer, and delayed learning outcomes.
The basic idea
A tutoring study needs more than a satisfaction rating. Measure the target knowledge before and immediately after tutoring, use a genuinely new transfer problem, preserve learner explanations, and schedule delayed retention as a later return visit. Keep answer keys out of tutor context and treat personalized versus standardized feedback as an explicit condition difference.
Randomly assign first-year chemistry students to a solo AI tutor, a three-model Council tutor, a human tutor, a human–AI chain, a fixed feedback script, or no tutor; then compare accuracy change, transfer, confidence, mental effort, observed help-seeking, and one-week retention.
How to do it
- 1
Choose Set up learning study in the participant-study builder and replace every placeholder item and answer key.
- 2
State the learning objective and learner level, then add the desired tutoring presets in the Guided Condition Builder.
- 3
Make the immediate and delayed items equivalent without exposing their scoring keys to tutors; add a distinct transfer problem and retain open explanations for blinded coding.
- 4
Set the retention delay and response window, pilot every condition and return link, lock the protocol, and inspect completion, interaction, accuracy, confidence, cost, and delayed-response diagnostics by condition.
What to watch for
- A no-tutor condition must make no model call; a standardized-feedback condition should display the exact locked script rather than an LLM paraphrase.
- Self-reported misconception correction and explanation usefulness are not substitutes for objective pre/post accuracy or blinded explanation coding.
- Delayed-retention attrition can differ by condition, so report invitation and completion rates and prespecify missing-data handling.
