One formulation of confidence scoring requires the examinee to indicate as a number his personal probability of the correctness of each alternative in a multiple-choice test. For this formulation a linear transformation of the logarithm of the correct response is maximized if the examinee accurately reports his personal probability. To equate…

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…

A specially designed answer format was used for three tests in a college level agriculture class of 19 students to record responses to three things about each item: (1) the student's choice of the best answer; (2) the degree of certainty with which the answer was chosen; and (3) all the answer choices which the student was certain were incorrect.…

On the basis of past research efforts to improve multiple-choice test information through differential weighting of responses to wrong answers (distractors), two statistical indices are developed. Each describes the properties of response distributions across the options of an item. Jaspen's polyserial generalization of the biserial correlation…

The concept of testing for partial knowledge is considered with the concept of tailored testing. Following the special usage of latent trait theory, the word valdity is used to mean the correlation of a test with the construct the test measures. The concept of a method factor in the test is also considered as a part of the validity. The possible…

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…

The admissable probability measurement (APM) format was used to score a criterion referenced language arts test administered in an inner city junior high school. Its 30 items covered capitalization, punctuation, parts of speech, and sentence analysis. With APM, students indicate their confidence in their answer choice, and guessing is heavily…
