Force Concept Inventory—FCI—My Results Are In for 2013-2014

I administered the “pre-test” Force Concept Inventory (Halloun, Hake & Mosca, 1995) to my class a few days after school started on September 5, 2013.  I scanned all the responses (N=16).  Just a few days ago, May 19, 2014, I administered the “post-test”.

Madsen, McKagan and Sayre (2014) suggest an effect size to help report scores.  I adopt their table here to present my own results

Raw Gain 9.2-8.0 = 1.2
Normalized Gain 0.05
Effect Size 0.35

I clearly have a lot of work to do to improve my teaching effectiveness.  If I twiddle the student scores, say improving them each by 10 points, then my normalized gain and my effect size would both increase by a factor of 10.
