a. Use heuristics rather than algorithms
b. Have large working memory capacities
c. Understand the logic underlying the procedures they use
d. Focus on only one small part of a problem at a time
Question 2
Three of the following examples illustrate the use of scaffolding in promoting students' problem-solving abilities. Which example does not illustrate scaffolding?
a. Ms. Amayo presents an example of a computer program that alphabetizes a list of names. She then has students do something similarwrite a program that puts items in numerical order.
b. When students struggle with arithmetic word problems, Ms. Blake gives them subtle hints about how to proceed.
c. Mr. Charlesworth gives easy, straight-forward problems at first, then gradually progresses to more difficult ones.
d. Mr. Darlington makes sure that all students know physics concepts well before he asks them to solve problems.
