We report on a concept inventory for special relativity: the development process, data analysis methods, and results from an introductory relativity class. The Relativity Concept Inventory tests understanding of relativistic concepts. An unusual feature is confidence testing for each question. This can provide additional information; for example,…

In a confidence weighting situation, the examinee is asked to indicate the correct answer, and how certain he or she is of the correctness of that answer. This paper reviews the bases for confidence marking, its validity and accuracy in evaluating students, and it's use in research. (BW)

The present study was an attempt to alleviate some of the difficulties inherent in multiple-choice items by having examinees respond to multiple-choice items in a probabilistic manner. Using this format, examinees are able to respond to each alternative and to provide indications of any partial knowledge they may possess concerning the item. The…

Medical and dental students were administered two short confidence-scored tests on cellular and molecular biology. Increases in test reliability and predictive validity were found when test scores were adjusted for realism, but were not statistically significant. (Author/MH)

The first four chapters of this report primarily provide an extensive, critical review of the literature with regard to selected aspects of the criterion-referenced and mastery testing fields. Major topics treated include: (a) definitions, distinctions, and background, (b) the relevance of classical test theory, (c) validity and procedures for…

A student's choice of an answer to a test question is a coarse measure of his knowledge about the subject matter of the question. Much finer measurement might be achieved if the student were asked to estimate, for each possible answer, the probability that it is the correct one. Such a procedure could yield two classes of benefits: (a) students…

Sixteen Family Practice faculty members completed ratings on 59 senior medical students after a 6-week primary care clerkship. Each student was rated by seven to ten faculty members and the chief residents who worked with them, resulting in a total of 353 ratings. The rating scale covered: (1) attainment of learning objectives; (2) progress during…
