Overview
Personalization is not only a matter of changing examples. It requires continuity. A teacher who remembers the mission and prior performance can choose a better next lesson than a system that starts from zero on every interaction.
Mission-centered learning also prevents aimless accumulation. The learner is not studying commands because they are common; the learner is acquiring the capabilities needed to ship a real system without fear, recover from mistakes, and trust the result.
Exercises and quizzes strengthen recall. In the Git example, the learner does not only read that version control provides safe points. The learner creates a directory, initializes a repository, creates a file, checks status, stages a change, commits a snapshot, and restores a broken file.
Retrieval questions then ask which command performs each action. The lesson checks active recall before moving on.
