Multiple Choice

To help her students improve their ability to solve multiple-step problems, Ms. Pohlmann uses the following procedure: First she shows them an example with all three of the steps worked out. Then she shows them a similar example that has only the first two steps worked out and requires them to complete the last step themselves. Then she gives them another similar example that has only the first step completed and requires them to work out the last two steps themselves. Finally, she gives them a fourth problem for which they have to work out all three steps. This procedure is called

A) breaking the problem into parts.
B) backward fading.
