Chaining

Chaining is a way to help people learn new actions by linking them together in a specific order. It works by creating a series of steps, where each step leads to the next one.

For example, when brushing your teeth, you start by seeing the toothbrush, then get toothpaste, put it on the brush, brush your teeth, spit out the toothpaste, rinse your mouth, and finally put away the toothbrush.

This method is used to teach complex actions that someone might not know how to do yet. The steps that need to be learned must be things the person can't do, not just things they won't do. There are three main types of chaining: forward chaining, backward chaining, and total task chaining. Each type helps in teaching the behavior chain in a different way.

Forward chaining

Forward chaining helps someone learn a series of actions step by step. The teacher starts by showing a signal to begin the first action. After the person does the first action, the teacher helps with the next actions. As the person gets better, the teacher adds more actions. The person keeps learning each step until they can do all actions by themselves. Rewards are given after each step, but the final reward comes only after all steps are done.

Backward chaining

Backward chaining is a way to help people learn new skills. It starts with the last step and then works backward. It is used for people who find learning hard. The good thing is that they see the result of the last step right away.

A teacher helps the learner through all the steps, starting with the final action. This continues until the learner can do the last step by themselves when asked. Then, the teacher helps with the step before the last, while still guiding the other steps. This keeps going until the learner can do all the steps without help.
