Metacognitive knowledge is a necessity in starting learning process. Solving physics problems requires metacognitive knowledge which comprises factual, conceptual and procedural knowledge. The purpose of metacognitive knowledge is to train students in developing their abilities in higher order of thinking. The problem is what kind of strategies can be used by teachers to facilitate studentâ€™s comprehension? This study used "sketch knowledge strategy (SKS)" as a strategy to help students in solving high order of physics problems and its influence on their metacognitive understanding. The target variable strategy was used as a comparison in order to examine its effects. The results showed that the concept of sketch strategy was more significant in solving metacognitive problems than that of the target variable strategy.
Keywords: Metacognitive knowledge, sketch knowledge strategy, target variable strategy.
