This page is dedicated to my experimental gain score.  The environment from which this data is based is an elementary level music class.  Taken from this environment is each students scores from their pre and post tests on identifying pitch syllables.  From this data, the overall class gain was calculated, that is, the percent increase from pre to post test that each student received.  Turns out, there was a 39% increase in learning from the beginning to the end of my course (figuratively speaking of course)!  Check it out…
