The effects of reinforcement on four different intelligence test measures for 72 trainable mentally retarded children was investigated. The Lorge-Thorndike Vocabulary, WISC Arithmetic, Picture Arrangement, and Comprehension subtests were administered. Reinforced administration resulted in superior performance on all but the Comprehension test.…

Procedures are described which yielded very high inter-judge reliability in grading creative writing.

The split-population exponential design suggested by Maltz and McCleary to predict parolee recidivism (TM 502 998) was applied to discharged psychiatric inpatients. Parameter estimates changed systematically as greater and greater observation time was allowed in the computation, thus limiting extrapolability. (Author/GDC)

A single conceptual and theoretical framework for sampling any configuration of data from one or more population matrices is presented, integrating past designs and discussing implications for more general designs. The theory is based upon a generalization of the generalized symmetric mean approach for single matrix samples. (Author/CTM)

Two multiple-choice scoring schemes--a partial credit scheme and a dichotomous approach--were compared analyzing means, variances, and reliabilities on alternate measures and student reactions. Students preferred the partial-credit approach, which is recommended if rewarding for partial knowledge is an important concern. (Editor/JT)

Predicted internal consistency, compared to inconsistency, would be associated with higher individual outcomes in congruent situations and with lower individual outcomes in incongruent situations. Assessment of professionals' (N=175) organizational commitment, professional commitment, job satisfaction, and job involvement revealed predicted…

Rating scales that were potentially useful for evaluating clinical performance were identified and were pretested for content and construct validity as well as interrater reliability. The range of interrater reliabilities was determined, and the construct and predictive validity of the rating using three classes of dental students was tested. (MLW)

This checklist provides guidance on how to measure adequacy of control and security of computer systems, identifies areas of risk, raises management and user awareness of their stewardship responsibilities, and reviews issues relative to system documentation, maintenance, integrity, and reliability.

A step-by-step outline is presented for testing the applicability of Lotka's law of scientific productivity. Steps include the computation of the values of the exponent and constant based on Lotka's method and the test for significance of observed frequency distribution against the estimated theoretical distribution derived from Lotka's formula.…

Investigated neuropsychological and cognitive basis of achievement and determined the stability of this relation. Addressed the power of the McCarthy Scales and portions of the Reitan-Indiana Test Battery for predicting academic achievement in kindergarten, and first grade; stability over a 2-year period; the ability of tests administered in…

A five by five covariance matrix representing longitudinal measurements at five occasions is used to illustrate that markedly different types of learning curves may generate indistinguishable covariance structures. An excellent fit of a simplex structure can be misleading. Common uses of covariance structure models for growth studies are…

Reports findings of interindexer consistency tests--quantitative measure of degree to which indexers agree in assignment of terms representing subject contents of document--on print materials, which may be generalizable to indexing of visual materials. Results of interindexer consistency test on nonspecialists indexing pictorial art works are…

Applies to the inclined-plane task Siegler's (1981) observation that performance on Piagetian tasks is governed by similar rule structures. Also replicates Siegler's original observations about the development on the balance-scale task and determines the consistency in children's rule usage across tasks. (Author/AS)

Twelve behaviorally disordered special education students were randomly placed in one of three groups: self-recording, self-recording plus backups, and a control group. On-task and academic responding was significantly higher for both experimental groups, but the performance of the two self-monitoring groups was not statistically different.…

Researchers and education leaders may seek to identify high-performing schools for at least three purposes. The first is to study how the practices in high-performing schools differ from those in average- or low-performing schools, in the hope that some of these practices will prove useful in improving other schools. The second is to use the…
