Since knowledge is a construction of humans and humans are constantly undergoing new experiences, knowledge can never be stable. The understandings that we invent are always tentative and incomplete. Knowledge grows through experience. Such a model provides opportunities for educators to implement open-ended, active learning into the classroom and to challenge learners in seeking further knowledge in the learning environment. Immanual Kant also asserted that human beings are not passive recipients of information.
Constructivism allows students to take ownership in acquiring their knowledge.
Hence, the student becomes the central focus and replaces the teacher-centered model of objectivism. Development of a functional understanding cannot take place unless students themselves go through the reasoning involved in the development and application of concepts. Existing knowledge must be ascertained and these structures must be active before new information can be learned. Knowledge must be acquired in whole, not in bits and pieces. After the whole has been learned, then the individual modules making up the whole may be disseminated and examined at length.
