All-pairs analysis The results of the all-pairs analysis of the first subjects showed that they did not understand this very well at all. Sowmya rewrote the training materials for this and presented it to several new subjects. The analysis of the all-pairs question for these five subjects follows. There are several parts of the problem of generating an all-pairs table. First, identify a reasonable set of variables to test. Second, correctly perform the mechanics of generating the all-pairs table. I believe that a good all-pairs table for this problem would have four variables, and require two different sets of all-pairs I believe that a good all-pairs test for this problem would have two distinct all-pairs tables. This is because several of the variables are mutually interdependent and cannot be tested separately. Splitting these four mutually interdependent variables into two sets gives the two tables. One set could use the width and height, the other set could use the Sized and the Orientation: Slides. These would be combined with the two independent variables: Orientation: Notes, and Number of Slides. None of the subjects analyzed the problem this way. All analyzed it as if several interdependent variables were independent, even though this is false to fact. Two subjects made other errors in the analysis. One didn't test custom sizes. Another had only three independent variables, not four. Given the analysis that they did, all of the subjects generated all-pairs tables that were completely or mostly correct. One subject got the first three iterations correct, then completely messed up the fourth iteration. Another generated a table that was completely wrong, but the error was probably a bad copy-and-paste for the first variable. (For that variable, all values listed were the same.) Making a very reasonable correction to this answer would lead to it being completely correct. Dependencies Of the five subjects in the second group, all answered this by detailing the dependencies, but not how to test them. This could be poor test-taking skills, but I think it is more likely that the subjects didn't know how to answer the question of testing the dependencies. McGeeReport v1.doc 3 03 January 2004 09:01
Question e All the subjects in the second group answered this question, but I did not have the question, so I cannot tell whether the answers were correct or not. General impression Overall, I did not get the impression that any of these subjects understood the material well enough to apply it to a new situation. I believe that they mostly could apply these techniques to situations that were very similar to the examples they had been trained on. In terms of Bloom's Taxonomy, I believe they learned the material mostly at level 3 (Application.) McGeeReport v1.doc 4 03 January 2004 09:01
