Figure 9.8 Group B combined responses by question category.
I-don’t-know responses: these dropped across the categories by an average of 25%. The
biggest drop of 32% was in the glass system category, followed by project delivery at 29%.
The smallest drop of 18% in the structure category is due to the relatively low “don’t know”
response in the 1 st test at 33%.
Correct responses: Again the general positive pattern to the increase in correct responses
is apparent. There is an average 26% increase in correct responses across the categories.
The highest increase is in glass at 37%, followed by performance criteria at 30%.
Incorrect responses: In a similar pattern with Group A, these responses dropped by only
1% in the 2 nd test, the large majority of the participants not changing their incorrect response
from the 1 st test, not swayed by the learning program or the handout. Once again, this may
reflect the difficulty in learning anything already perceived as known. The biggest drop in
