A teacher shows her students a completely worked out solution to a multiple-step problem. She then shows them similar examples with fewer and fewer of the steps worked out and requires them to complete the missing steps. Finally, she gives them a similar multiple-step problem they have to solve on their own. Which of the following is the correct name for this procedure? O Solving an analogous problem. O Backward fading. Breaking the problem into parts. Working on a simpler version of the problem first
