According to Ted Sizer (1990) who is widely credited for re-invigorating Exhibitions in the late 1980’s:  “In its original form, the exhibition is the public expression by a student of real command over what she’s learned….It began in the eighteenth century, as the exit demonstration in New England academies and in colleges like Harvard. The student was expected to perform, recite, dispute, and answer challenges in public session. [If such a performance is well designed, Sizer points out, it elicits proof both of the student’s understanding and of some imaginative capability-it serves at once as evaluative agent and expressive tool.] “We expect people to show us and explain to us how they use content-it’s more than mere memory….It’s the first real step towards coming up with some ideas of their own.”
