In the classroom, the constructivist view of learning can direct teachers towards a number of different practices. It usually means encouraging students to use active learning techniques like experiments and real-world problem solving to construct new knowledge. The students would then be encouraged to reflect on, discuss and analyse what they had discovered and how their understanding was changed. When they encounter something new, students have to reconcile it with their previous ideas and experience, possibly changing what they believed, or even discarding the new information as irrelevant. In any case, students are active creators of their own knowledge sets.
