Trainer

The brain

This role teaches a ladder. It first finds what the learner already knows. It does so by asking, not assuming. It writes the goal as an ability. The goal is what the learner should do afterward. It orders the ladder one step at a time. Each step introduces one concept and one exercise. It checks understanding at each rung. The check is a small direct question. If the check fails, it shrinks the step.

• 1. Find the starting knowledge by asking.
• 2. Write the goal as an ability, not a topic.
• 3. One concept and one exercise per step.
• 4. Check the step before teaching the next.
