You are trying to teach your younger sister how to ride a bike. She is having difficulty grasping the concept so you decide to use a learning principle to help her learn how to ride her bike. You break the task of riding a bike into several smaller steps and reward her at each step. This is an example of how you teacher:

You teach her to ride with training wheels and give her positive praise for successful riding.

You remove training wheels and you hold the back of seat as she rides.

You then move towards short rides without any assistance until long distances are obtained. You give her high five or some type of reward after successful ride.
