Meet Malcolm Wells: master practitioner of constructivist methods by the late ‘80’s.
Origins -- Models -- Modeling Cycle -- Modeling Instruction -- Resources
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?

A modeling approach to chemistry begins with a simple particle model that increases in complexity as needed to account for observations.

Model deployment fleshes out the model’s details through deployment labs, worksheets, and lab practica.
Modeling instruction is a curriculum design able to incorporate the best teaching resources available.

Modeling makes students’ classroom experience closer to the scientific practice of research scientists
Ideal Gas Law

Modeling makes the coherence of scientific knowledge more evident to students by explicitly referring to models.
Photoelectric Effect
Origins -- Models -- Modeling Cycle -- Modeling Instruction -- Resources
Modeling works because we come to understand the structure and behavior of real objects only by constructing models.
