The confirmatory…

In the study described in this article, primary school teachers' pedagogical content knowledge (PCK) of technology education was measured with a multiple choice test; the Teaching of Technology Test (TTT).

Proposes a factorial procedure for investigating differential distractor functioning in multiple choice items that models each distractor with a distinct distractibility parameter. Results of a simulation study show that the parameters of the proposed modeling were recovered very well. Analysis of 10 4-choice items from a college entrance…

Factor analysis was used to determine whether computerized patient management problems had the same factor structure as multiple choice examinations and rating scales. It was determined that the factor structure was similar to the examinations but not the rating scale. (JKS)
