Pre and post testing results are from the Cantara Elementary School in Reseda, CA (2014). This research was executed by The Dietetic Program at California State University at Northridge, CA.
The percentage of correct responses was compared to the percentage of correct responses at posttest for the 3rd graders, and the total sample (grades 2nd to 5th). As shown below, for each of the groups there was a significant increase of correct answers from pretest to posttest for each subsample.
These results indicate that the musical significantly increased nutrition and physical activity knowledge from pre to post.
