Wissen ist immer konstruiert. Neues Wissen kann nur erworben und genutzt werden, wenn es in die vorhandenen Wissens- strukturen eingebaut und auf der Basis individueller Erfahrungen interpretiert wird.

One of the foundational premises is that children actively construct their knowledge rather than simply absorbing ideas spoken at them by teachers. It posits that children actually invent their ideas. They assimilate new information to simple, pre-existing notions, and modify their understanding in light of new data. In the process, their ideas gain in complexity and power, and with appropriate support they develop critical insight into how they think and what they know about the world.
