This paper explains how analysis of covariance (ANCOVA) and related statistical corrections work and discusses difficulties with the use of these corrections under certain circumstances. ANCOVA is essentially a regression of a covariate variable on the dependent variable from the entire sample ignoring group membership, at least, if ANCOVA…

In the technique developed by K. G. Joreskog to solve the problem for oblique rotation to a specified simple structure, the basic concept is that the simple structure solution itself is determined only by the zero coefficients of the reference-structure matrix and not by the coefficients of non-zero magnitude. Following this, prior information…

The chronicle provides information on programs and offers articles of interest to gifted students and educators. Among entries are the following: "The Testing Maze" (about the various tests students are faced with); "Using Community and Family Resources for the Gifted Student" by E. Kearney; "Study Skills: Basic Strategies for Learning" by W.…

Data were reanalyzed from previous studies to attain ratio scores between right/wrong answers on test one or test two. Feedback was either immediate or delayed between test one and test two. The interference-perseveration theory was found superior to the verbal rehearsal theory in explaining the delayed retention effect. (Author/BJG)

Proposes three different multiple range tests based upon the Newman-Keuls philosophy with respect to significance levels. The three tests utilize the Fmax statistic, Cochran's statistic and a normalizing log transformation of the sample variances respectively. (Author/RC)

A sequential testing model is proposed which employs discriminant functions to classify examinees into groups which could correspond to instructional treatments. A termination rule based on the computed posterior probability of group membership is suggested. (Author)

This paper describes three investigations conducted by the University of London School Examinations Department into the possible use of stimulus questions, containing original historical material such as cartoons, maps, photographs and statistics, in the 'O' level history examination. (Author)

A Monte Carlo technique was employed in order to compare the relative power and robustness of the Bartlett, Cochran, Hartley, and Levene tests for homogeniety of variance. (Editor)

The use of a university exam to test the effects of ESP produced essentially overlapping distributions of performances by the experimental and control groups. (Author/KM)

Analyses of repeated measures to evaluate the role of active and passive instructions showed decreased test anxiety somewhat more with the use of active instructions. (Author/KM)

A procedure for item analysis using distance clustering is described. Items are grouped according to the predominant factors measured, regardless of what they are. The procedure provides an efficient method of treating unanswered items. (Author/RC)

Authors attempted to summarize what they thought their experiments show, why the notion of testing recall and recognition under identical conditions made no sense, and their view of the theoretical implications of their experiments. (Author/RK)

The Simulated Oral Proficiency Interview (SOPI) is a semi-direct speaking test that models the format of the Oral Proficiency Interview (OPI), an oral proficiency test used by government agencies to assess general speaking proficiency in a second language. The SOPI is a tape-recorded test consisting of six parts. It begins with simple, personal…

Computer-assisted testing is not without its problems and pitfalls, but it holds a great deal of promise as well. Computer administration of tests provides more control over the testing process than was ever possible with paper-and-pencil testing. At the same time it offers the possibility of being able to monitor and record aspects of the testing…
