Describes a classroom demonstration that illustrates the error of using an inappropriate test to conclude that a specific ability does not exist within a subject or a population. Shows ways to expand the lesson to cover the issue of null conclusions. Points out social and methodological implications of the demonstration. (Author/LS)

Reports a quasi-experimental study involving an objective test that was intentionally mis-scored on the copies of the exam returned to students. Results showed that not all perceived errors were reported and that the decision to report errors appeared dependent on whether reporting was to the benefit of the student. (Author/JDH)

Because the science of nursing is still at an early stage of development, nurses involved in clinical research often find that no appropriate measures are available to sample the theoretical construct of interest. Researchers often must design and test new instruments before proceeding to test theory. A study of the effect of nurse-client…

The biasing effects of a pretest on subsequent post-test results were investigated in two experimental studies. In general, the results argue for using designs without pretests. (Author/JKS)

Factor analysis is of limited value in investigating the influence of students' implicit theories about teachers' behaviors on student evaluations of teachers. (MH)

The effects of humorous test questions on test performance of high and low-anxious college students was investigated. It was hypothesized that humor should reduce the anxiety level of high-anxious subjects, and thus improve their performance, while having little effect on low-anxious subjects. Students were assigned to a low or high-anxious group…

This study reexamines results reported by Angoff and Schrader regarding formula directions and rights directions for standardized tests. In that study, it was concluded that the two scoring directions were essentially equivalent. In this study, methodological concerns are discussed and additional data analyses undertaken. Among various…

Research on the quality of foreign medical graduates (FMG) in terms of their competence or manifest abilities as measured by examinations, and their performance or actual behavior is briefly reviewed. In addition, some of the methodological problems that make research on foreign medical graduates difficult to interpret are critiqued, and…
