BACKGROUND Examinations are necessary for assessment of student proficiency in medical education, but comparison of achievement across different cohorts in different tests is challenging. We applied psychometric test equating methods to compare student proficiency in two different examinations for a clinical anesthesiology course. METHODS Each examination contained 50 multiple choice items an...

BACKGROUND The flipped classroom is an educational approach that has had much recent coverage in the literature. Relatively few studies, however, use objective assessment of student performance to measure the impact of the flipped classroom on learning.

This study designed a system called ASEE, which can answer the multiple-choice items provided by the QALab-2 task in NTCIR-12 conference. This system adopts Wikipedia as its knowledge source, using the Stanford Parser to analyze the linguistic features of the items and retrieve key words; it then determines the probability of each option as the correct answer through an algorithm and finally se...

This paper evaluates certain guidelines for writing multiple-choice test items. The analysis of the responses of 5013 subjects to 630 items from 21 university classroom achievement tests suggests that an option should not differ in terms of heterogeneous content because such error has a slight but harmful effect on item discrimination. This also occurs with the "None of the above" option when i...

In an earlier study (Koretz, 1997), we reported that Kentucky had been unusually successful in testing most students with disabilities, but we found numerous signs of poor measurement, including differential item functioning in mathematics, apparently excessive use of accommodations, and implausibly high mean scores for some groups of students with disabilities. This study used newer data to te...

This paper describes a planning methodology and tools for a truncated SPRT (sequential probability ratio test) for checking the means ratio of the times between failures (assumed to be exponentially distributed) of two items. The problem is considered for the situation in which the ratio may differ from unity, whereby the results are applicable for any specified ratio, or wherever multiple copi...
