Note. Group HS = high school audience (grades 9-12); Group RA = Recital Audience (mixed
ages).
The HS presentation was given to four different classes (HS classes 1, 2, 3, and 4). For each of
the classes, each treatment (no treatment [N] and introduction by discussion [ID]) is given twice.
This effectively doubles the amount of data that is collected from each class. A similar procedure
was followed for the four recital audiences (RA recitals 1, 2, 3, and 4).
