Mathematical Problem Solving Practices of High School Children: Factors Influencing Choices of Strategies.

In this work we investigated the problem solving behaviors of 3 highschool students as each solved four common non-routine problems with the goal to trace performance constancy across different subject areas and problem types. Additionally, we aimed to identify possible factors that influenced children's choices of heuristics in different problem contexts. The results suggested the individual's confidence and preference for the use of certain strategies. Inconsistency in the same individual's mathematics problem solving behaviors across different subject areas was revealed.
