abstract
Formal education is expected to develop children's understanding of the interrelationship between intensive and extensive quantities. Thus, studies were conducted to examine not only children's understanding of density but also the interrelationship of these quantities. These studies have shown that children's understanding of the interrelationship of these quantities differ from formal conceptions. More specifically, the problem lies on the qualitative rather than the quantitative understanding-that is, inability to differentiating density from weight, qualitative understanding interrelationships, and equal distribution. Because these misconceptions are strong and deeply-rooted, improving children's understanding is difficult. There is, therefore, a need to develop learning strategies that can effectively promote qualitative understanding and apply these in the classrooms.
