Constructivism Online

The constructivist approach also strongly supports active learning. Based in social constructivism of the early and mid 20th century, this approach to teaching and learning suggests that we, as instructors, do not impart knowledge, rather we help our learners to build thier own personal knowledge. We can best do that through active learning.

1. Knowledge involves active cognizing by the individual.
2. Knowledge is adaptive, facilitating individual and social efficacy.
3. Knowledge is subjective and self-organized, not objective.
4. Knowledge acquisition involves both sociocultural and individual processes.
