General Physics Education Research
One of the primary questions we would like to answer through the research into educational engineering is how a standardized concept inventory relates the the total information presented in a class. A related topic, is the context sensitivity of the Force Concept Inventory.
The graph to the right shows the percentage of the wrong answers on a concept inventory that results from strongly held misconceptions is predictable from the performance on the problem and decreases as the performance increases.
Toward a Normalized Conceptual Gain - Constucts a correction to the Hake Gain to remove the effect of guessing on the pretest.  

Context Sensitivity and Uncertainty in the Force Concept Inventory Heather Griffin's thesis an extended analysis of the role student uncertainty plays in the Force Concept Inventory and a finding that the FCI has minor context sensitivity problems.

APS Talk A talk based on Heather's research given at the Denver APS meeting.
