The Basics of Constructivism

Bartlett (1932) pioneered what became the constructivist approach (Good & Brophy, 1990). Constructivists believe that "learners construct their own reality or at least interpret it based upon their perceptions of experiences, so an individual's knowledge is a function of one's prior experiences, mental structures, and beliefs that are used to interpret objects and events." "What someone knows is grounded in perception of the physical and social experiences which are comprehended by the mind." (Jonasson, 1991).

If each person has their own view about reality, then how can we as a society communicate and/or coexist? Jonassen, addressing this issue in his article Thinking Technology: Toward a Constructivist Design Model, makes the following comments:

• "Perhaps the most common misconception of constructivism is the inference that we each therefore construct a unique reality, that reality is only in the mind of the knower, which will doubtlessly lead to intellectual anarchy."
  


• "A reasonable response to that criticism is the Gibsonian perspective that contends that there exists a physical world that is subject to physical laws that we all know in pretty much the same way because those physical laws are perceivable by humans in pretty much the same way."
  
  
• "Constructivists also believe that much of reality is shared through a process of social negotiation..."
  

If one searches through the many philosophical and psychological theories of the past, the threads of constructivism may be found in the writing of such people as Bruner, Ulrick, Neiser, Goodman, Kant, Kuhn, Dewey and Habermas. The most profound influence was Jean Piaget's work which was interpreted and extended by von Glasserfield (Smorgansbord, 1997).

Realistic vs. Radical Construction

Realistic constructivism - cognition is the process by which learners eventually construct mental structures that correspond to or match external structures located in the environment.

Radical constructivism - cognition serves to organize the learners experiential world rather than to discover ontological reality

(Cobb, 1996, in Smorgansbord, 1997).

The Assumptions of Constructivism - Merrill

• knowledge is constructed from experience
  
• learning is a personal interpretation of the world
  
• learning is an active process in which meaning is developed on the basis of experience
  
• conceptual growth comes from the negotiation of meaning, the sharing of multiple perspectives and the changing of our internal representations through collaborative learning
  
• learning should be situated in realistic settings; testing should be integrated with the task and not a separate activity
