That is, through interacting with and manipulating objects, subjects come to know the principles that organize the object's properties. Number is not something with an independent objective existence with which children have a particular concept. The study of number is the study of something in evolution or something in the process of construction. The constructivist asserts that children don't conceive number, rather they construct it. This concept will not come to a child all at once, but in a process of building intellectual structures that form a relationship of change, interaction and combining.
Constructivists feel that every one brings different ideas and concepts to a learning situation.
Therefore, it can be concluded that everyone takes away different ideas and concepts from the same learning situation. A conflict occurs, for example, when new knowledge is introduced that is not consistent with already known knowledge. In order to bring about resolution, new learning must occur. Reflection is used to construct or transform the learner's representation to reality. This restructuring of information must occur through self-regulation.
