Goal
The result the system is trying to maintain or reach.
Curriculum topic
Feedback
Feedback happens when a system checks the result of an action and uses that information to adjust what it does next.
Why it matters
A small idea that returns in larger systems.
A command can start movement, but feedback makes movement correctable. Games use score and collision signals; robots use sensor readings; people use visible results to improve a design.
Real-world connection
A person steering a bicycle makes many small corrections after seeing where the bicycle goes. A robot patrol can do something similar with repeated sensing and turning.
The connection shows where the idea returns; it does not claim every advanced application is taught in this first topic.
Math and logic kernel
The structure beneath the project.
Observation
Information about the current result.
Difference
How current behaviour differs from the goal.
Correction
A change intended to reduce that difference.
Small examples
Make one relationship visible at a time.
Boundary correction
Move a sprite back when it leaves a region.
Line following
Adjust direction after reading a surface.
Speed tuning
Change movement after measuring timing.
Player feedback
Use sound or display to make a system state visible.

Common mistakes
Useful clues, not reasons to stop.
Correction without measurement
The system changes repeatedly without checking whether it helped.
Correction too large
The result swings past the goal.
Feedback too late
The system reacts after the useful moment has passed.
Hidden goal
Students cannot explain what the system is trying to maintain.
Lesson and projects
Use the idea inside a working system.
