Problem solvers use both domain-general and domain-specific knowledge when solving problems. Suppose a child is asked to mentally solve the arithmetic problem 25 + 26 = __
Cite one example of domain-general knowledge and one example of domain-specific knowledge that the child may use to solve this multi-digit addition problem.
What will be an ideal response?
The child may use domain-general knowledge, such as knowing that it is important to encode all problem features accurately, or knowing that rehearsal is a good strategy for maintaining intermediate sums in memory. He or she may also use domain-specific knowledge, such as knowledge of specific strategies for solving multi-digit addition problems that involve carrying, or knowledge of specific number facts like 6 + 5 = 11.
