On-Line Assessment of Expertise
Abstract
There were two main objectives during this report period. The first was to extend Olae's physics rule base or cognitive domain model to include incorrect rules and correct but unusual rules. The second was to determine whether Olae was able to match fine-grained assessments performed by a person. Although Olae can model many correct and incorrect solution methods, the students in our first sample occasionally acted in unexpected ways. Before this reporting period, Olae's and Cascade's physics rule base was sufficient to solve many problems in several chapters of introductory physics and contained some common buggy rules. To account for the unexpected methods, we added rules sufficient to produce the behavior exhibited by the students. Of course, because we used this sample to augment the rule base, we will collect another sample to evaluate Olae.
