Does knowledge exist outside of, or separate from, the individual who knows? constructivists argue that human knowledge, such as what is known in the fields of mathematics or sociology, as well as knowledge about learning itself, is a human construction (gredler, 2001).

knowledge exists only withiin the individual, who is the being who knows, in this way it is inside, and cannot be separated from the individual

Explanation:

According to classical constructivism learning while always be experience based, the proponets like Vigotsky and Piaget put great emphasis on agency and the knowledge prior that someone has before learning. Many other factors have to be taken into account as social and cultural backgrounds.

Piaget argued that people create knowledge and make meaning based on what they previously know. This applies to learning, teaching and education as a whole. He established accommodation and assimilation are important  components of knowledge . Assimilating knowledge  makes someone incorporate new experience into the existing ones.

If misunderstanding existed, the learning person while reflect, rethink and alter the perception. Accomodation then means reframing the view of the world and new experiences will take please when the mind opens to new as well.

Thus knowledge exists for people as they form meanings based on their experiences.
