The testing of Group A was administered in a manner that facilitated participation by the
subjects in both tests. Even in this group however, one participant failed to respond to the
2 nd test. This was more of a problem with Group B.
9.1.2.3 “B” Groups
Friday, 22 February 2008: The identical test was distributed to Group B before the
presentation of the identical leaning program to this group. Again, testing took approximately
10 minutes to complete. The test forms were then collected and the program presented,
lasting approximately one hour as before. In contrast with Group A, Group B was not
retested until over two weeks later. The participants were not told that they would be
retested. On 10 March 2008 the participants were given a nearly identical test (the test
included some additional qualitative questions not included on the first test) along with a
handout documenting the presentation they were given two weeks earlier. They were
instructed to complete the test again, and told that they could use the handout if needed.
The handout is intended as a prototype tutorial. The material was left with the subjects, and
picked up two days later.
Only seven of the original 12 participants responded to the 2 nd test. Two participants of the
2 nd test did not participate in the 1 st test. These two are excluded from the base B Group
used in comparative analysis between Groups A and B, but they are included with the base
group in the subjective responses discussed below. As the two participants represent a
unique case, they have been designated as Group B3
Another useful differentiation of the B Group is with respect to those who used the tutorial
and those who did not. Participants who responded to subjective questioning indicating they
did use the tutorial were used to populate a Group B1; those that did not use the tutorial (or
indicated that they did not rely on it or use it much) were delegated to a Group B2. Only
