Four monte carlo simulation studies of Owen's Bayesian sequential procedure for adaptive mental testing were conducted. Whereas previous simulation studies of this procedure have concentrated on evaluating it in terms of the correlation of its test scores with simulated ability in a normal population, these four studies explored a number of…

True-false achievement test items written by typical classroom teachers show about two-thirds of the discrimination of their multiple-choice test items. This is about what should be expected in view of the higher probability of chance success on the true-false items. However, at least half again as many true-false items as multiple-choice items…

Binary, probability, and ordinal scoring procedures for multiple-choice items were examined. In two situations, it was found that both the probability and ordinal scoring systems were more reliable than the binary scoring method. (Author/CTM)

Experiments tested the predictions that words are perceived more accurately in strongly constraining word contexts than in weakly constraining word contexts, and that a strong perceptual advantage would be present for letters in words vs. letters alone or in unrelated-letter strings. Several alternative theories of word perception are discussed.…

Advantages and disadvantages of no-penalty and penalty marking systems are discussed. Ways in which examiners have attempted to correct for guessing by students are reviewed, along with the use of "don't know" options and confidence-weighting for attempting to assess the degree of certainty that candidates attach to their answers. (Author/LBH)

Ninety-seven fifth graders took a multiple-choice test with factual and guess questions after reading a 900-word text. The effects of immediate informative feedback, delayed feedback, or no feedback on their performance on a delayed retention tests were analyzed. Results suggested that awareness of initial errors was helpful. (Author/BS)

An experiment is reported in which attention to one channel of a dichotic presentation was controlled by requiring S to memorize the list of verbal items presented over that channel. (Author)

Results were interpreted in terms of an initial tendency for Ss to guess in order of frequency followed by a change to guessing words at the appropriate frequency level. (Author)

Responds to Fry's article in the January 1971 Reading Teacher, The Orangoutang Score." Suggests that chance level scores should not be assumed to have arisen only from random processes and that there are methods for identifying a thoughtful, nonrandom performance. References. (VJ)

Alternate versions of Hutchinson's theory were compared, and one which implies the existence of partial knowledge was found to be better than one which implies that an appropriate measure of ability is obtained by applying the conventional correction for guessing. (Author/PN)

This paper focuses on mixtures of two binomials with one known success parameter. It is shown how moment estimators can be obtained for the remaining unknown parameters of such mixtures, and results are presented from a Monte Carlo study carried out to explore the statistical properties of these estimators.

A mathematics achievement test with instructions to avoid guessing wildly was given to 168 elementary school pupils who were later asked to complete all the questions using a differently colored pencil. Results showed examinees, particularly the more able students, tend to omit too many items. (CTM)

A teacher explains two techniques he has used in high school English classes to increase students' confidence in their own abilities, by helping them to rely less on guessing when it comes to spelling and test-taking and more on realistic assessments of their own performance. (SJL)

Macready and Dayton introduced two probabilistic models for mastery assessment based on an idealistic all-or-none conception of mastery. Alternatively, an application of latent trait theory to mastery testing is proposed (a three parameter logistic model) as a more plausible model for test theory. (Author/CTM)

Multivariate and univariate analysis of variance indicated that students tested under a norm referenced condition earned higher achievement scores than those tested under criterion referenced conditions. A significant relationship was observed between risk-taking and achievement only under a criterion referenced condition. (Author/RC)
