Knowledge construction focuses on learning outcomes which reflect the intellectual processes of knowledge construction and entail higher- order thinking. The multiple perspectives method makes references to a domain of possible outcomes as acceptable evidences of learning. I am conservative about the overradical assertion that there is no shared reality. I believe there are external realities, some of which are stable. It is characteristic of human beings to keep inquiring, creating, or changing a reality.
Reality is shareable and needs to be shared.
All inquiries in physical and social sciences have been aimed at understanding and sharing reality. Human beings share basic realities such as the physical world and psychological needs. We do have differences. For instance, a Western bride wears a white gown but a Chinese bride wears red gown. We use different symbol systems to communicate within and between cultures.
