Despite the findings of science education research, science education remains highly transmissionist.

Meet Malcolm Wells: master practitioner of constructivist methods by the late ‘80’s.

In the mid 80’s Malcolm Wells learned about the precursor to the Force Concept Inventory and used it to gauge the effectiveness of his instruction.

Wells’ students did not do well on the precursor to the FCI, inspiring him to engage in graduate studies to determine what was missing from constructivist instruction.

Malcolm Wells worked with Dr. David Hestenes which began the modeling instruction program.

A small set of basic models forms the content core for the sciences.

Models are conveyed though pictorial, graphical, mathematical, and verbal representations.
What is Science? . . . What is Reality?
How is Science related to Reality?
