STRUCTURAL GLASS FACADES - USC School of Architecture

This question was answered incorrectly 18% and 30% of the time on the 1 st and 2 nd test
respectively by Group A, and 17% and 43% of the time on the 1 st and 2 nd test respectively by
Group B.
Group A: The two incorrect responders to this question in the 1 st test stuck by their answers
in the 2 nd test. In addition, one of the “don’t know” responders selected an incorrect response
in the 2 nd test. However, three of the I-don’t-know responders selected the correct response
in the 2 nd test.
There was a 24% drop overall in this category for the I-don’t-know response from the 1 st test
to the 2 nd . This seems to indicate the people thought they knew more about the responses
during the second test. What the increase in incorrect responses indicates is that what they
learned was not clear enough for them to select the best answer.
The program was seemingly effective in providing information that the users did not know. It
was not effective in teaching them things that the thought they new but were wrong about.
