Problem solving ability is recognized as a complex interplay between cognition and meta-cognition. A primary source of difficulty in problem solving may lie in pupils’ inabilities to actively monitor and subsequently regulate the cognitive processes engaged in during problem solving (Artzt & Armour-Thomas, 1992). An extremely important but often neglected aspect of learning is that students often have the requisite knowledge and skills for performing complex tasks but fail to use them. Sometimes it is because they are not motivated or confident to apply them, and sometimes because they do not recognize that the situation calls for the use of those skills (Hartman,2001a). That is, learners may have declarative and procedural knowledge, but not the contextual or conditional knowledge needed for its application and transfer.
