9.1.4 Summary of Results
9.1.4.1 A Group
Figure 9.1 Group A, percent right, wrong; 1st and 2nd tests.
The testing method for Group A is certainly no measure of retention, the test being given the
2 nd time immediately after the presentation of the learning program, but a comparison of the
pie charts in Figure 9.1 does, as one would expect, reveal an increase in the number of
correct responses. It is interesting that the compensating change in the other two categories
is almost entirely from the ‘don’t know’ category; the wrong answers stayed nearly the same
with only a 2% drop in wrong answers. The likely reasons for this are explored later in this
Chapter.
Figure 9.2 and Figure 9.3 show the same test results broken down by question category.
Figure 9.4 compares the responses of both tests by category.
