| Research Abstract |
The purpose of this research was to evaluate whether it is best to implement the item response theory as it applies to the design and evaluation of the nationwide common achievement test (CBT ; Computer Based Testing). This test is taken by medical and dental students prior to starting their clinical clerkships. Moreover, it has the purpose to understand how CBT scores can vary according to factors other than achievement of knowledge. We assessed other factors by questionnaire, such as the testing environment (the chair, illumination, room temperature, etc.), the students' preparation times for the exam, and other items. The time utilized in test preparation and the requirement of a clerkship prior to the exam best correlated with the CBT scores.
We performed an item characteristic curve, an assessment of item difficulty and discrimination within six areas of the core curriculum, using the item response theory. By using these, it is possible to more clearly analyze the results of the CBT. We then recorded in the item bank those questions which were evaluated as being reliable. We included random samples from this item bank along with 320 other questions to each student being tested. We were then able to estimate the ability score as adjusted among different test sets.
