Prepare
Use batteries only; inspect every wire.
Checkpoint: Materials and safety checkPhase 11 • Interactive production
Twenty guided investigations. Twenty interactive pathways. Zero invented evidence.
Every priority topic now has a guided investigation and an interactive learning model. Publication still requires independent review, reviewed narration and real teacher testing.
20/20interactive topic pathwaysTopic-by-topic approval
Physics • S1–S4
Simple electric circuits
Completed guided investigation • Low risk
What completes a safe electric circuit?
Materials: 1.5–3 V cells • lamp • wires • switch
Narration: Script complete • human recording and native-language review pending.
Predict
Sketch which connection will light the lamp.
Checkpoint: Prediction recorded before testingBuild
Connect one closed loop with a switch.
Checkpoint: Setup matches the visual modelTest
Open and close the switch; never short the cell.
Checkpoint: Only one variable changesRecord
Record lamp state and measured current.
Checkpoint: Evidence includes units or labelled observationsExplain
Explain why a closed conducting path matters.
Checkpoint: Claim is supported by evidence and reasoningIntelligent coaching ladder
Hints deepen only after difficulty repeats
Hint 1: Re-read the goal and identify the variable you control.
Current evidence: 0 repeated difficulties. The system records hint level, not private free-text reasoning.Publication review
