Learning hierarchies are networks of prerequisite relationships of instructional objectives. Seven measures of the validity of learning hierarchies were compared for their ability to identify correctly- and incorrectly-ordered hierarchies. A computer simulation model was used to generate stochastic data of known underlying structure. Analysis of…

A method of factor extraction specific to a binary matrix, illustrated here as a person-by-item response matrix, is presented. The extraction procedure, termed ERGO, differs from the more commonly implemented dimensionalizing techniques, factor analysis and multidimensional scaling, by taking into consideration item difficulty. Utilized in the…

This publication is an annual catalog of abstracts of research reports published by the institutes of psychology and education at teacher training colleges and universities in Sweden, complete to June 1, 1976. The reports are grouped into twenty-seven broad subject fields according to the rules of PSYCHOLOGICAL ABSTRACTS and EUDISED THESAURUS.…

For the sake of simplicity and brevity, the development of psychometrics is discussed mainly in the context of studies of individual differences. (Author/AM)

Systematic procedures are outlined for testing the assumption made on the dependent variables in a variety of statistical techniques. Specifically, procedures are outlined for testing the assumption that the dependent variables are measuring the same constructs in the same metrics with equivalent reliabilities across all subgroups. (Author/JKS)

The concurrent validity of the KIT was evaluated by correlating it with other tests of intellectual, perceptual, social, linguistic and psycholinguistic functioning, using a sample of 106 retardates. Positive correlations between the KIT and these other measures attest to its potential usefulness as a measure of intelligence. (Author)

Students rated the quality of the items on a classroom test taken previously and psychometric items were calculated. Results showed that student ratings were related to item difficulty and that better students rated items as less ambiguous. Ambiguity ratings were more highly related to the item-test correlations for better students. (Author/LBH)

This study evaluated the validity of the Type A behavior pattern as measured by paper-and-pencil questionnaires. The Jenkins Activity Survey, Framingham Type A Scale, Thurstone Activity Scales, a new bipolar adjective Type A measure, and measures of achievement and nurturance needs were completed by 418 students.

This study investigates the validity of the Self-Assessment of Relative Strengths in Teaching (SARST), an instrument which measures self-expressed competence in teaching techniques. Its psychometric properties are discussed, including construct validity, stability, and internal consistency. Suggestions for possible use of the instrument in teacher…

Outlines the procedures involved in the construction of the Canadian version of the Life Roles Inventory-Values Scale (Canadian Work Importance Study, 1986), developed in both French and English. Describes studies of the reliability (internal consistency, test-retest, and alternate form), and validity (construct, convergent, discriminant, and…

Three instruments designed to tap the self-system in normal IQ children were administered to 126 retarded children in mainstreamed and self-contained classrooms. Factor structures differed significantly from normal IQ results. The need to revise instruments for use with the retarded and to obtain social comparison information is emphasized.…

Examined stability of the Kaufman Assessment Battery for 53 at-risk preschool children. Over 9 months the stability coefficients for the global scales ranged from .78 to .88, and for the subtests from .65 to .79. Concluded that scores display adequate stability, but the Simultaneous scale is less stable than the Sequential or Achievement scales.…

Investigated the criterion-related validity of the Battelle Developmental Inventory (BDI) when used with 70 handicapped children less than 30-months-old. Compared scores with those on the Bayley Scales of Infant Development. Supported the validity convincingly using multivariate data analyses. Commends the BDI's value in assessing delays in…

Describes measurement problems associated with computer based testing (CBT) programs when they are part of a computer assisted instruction curriculum. Topics discussed include CBT standards; selection of item types; the contamination of items that arise from test design strategies; and the non-equivalence of comparison groups in item analyses. (8…
