I talked in previous posts about stimulus prompts in which we change what we present to the student to help him get the correct answer and get the reinforcer. It's important to recognize that prompting and reinforcement are the elements of instruction that make it different than testing. Just asking a student to do something and seeing if he does it is testing. Even asking him to do something, seeing him do it correctly and reinforcing him is only going to go so far. If we are teaching a skill from scratch (i.e., the student doesn't ever exhibit it at the right time) then if we simply wait for him to display the behavior so we can reinforce it, we are going to be waiting a long time and learning is not going to be at all efficient. Prompting is the way to speed things up.
Probably the most common type of prompt that we use is response prompts where we do something at the same time or after we give the direction or discriminative stimulus to spark the correct response from the student. Often this involves a gesture, a physical prompt, or a verbal prompt--see the infographic about different types of prompts HERE. To be effective with response prompts, we have to make sure we fade them out. There are several strategies that can be used for fading. It's important to decide which strategy you are going to be using and make sure everyone working with the student on that skill are aware of that decision. Visuals for adults (see the freebie below) can be helpful reminders.
