Few empirical investigations have evaluated learning disabilities (LD) identification methods based on a pattern of cognitive strengths and weaknesses (PSW). This study investigated the reliability of LD classification decisions of the concordance/discordance method (C/DM) across different psychoeducational assessment batteries. C/DM criteria were…

Item response theory (IRT) and related latent variable models represent modern psychometric theory, the successor to classical test theory in psychological assessment. Although IRT has become prevalent in the measurement of ability and achievement, its contributions to clinical domains have been less extensive. Applications of IRT to clinical…

Purpose: To describe a cognitive neuroscience model of memory that can be used to guide assessment and promote consistent terminology among members of the rehabilitation team, and to relate the model to frequently used assessment measures. Method: Description of a model of memory, description of how frequently used memory measures relate to the…

It is commonly proposed that educational and psychological assessments consist of a multifaceted procedure that incorporates scores from a variety of tests and resources. Little guidance has been offered regarding the method for selecting a combination of testing instruments used in an evaluation. The problem of test selection is discussed in the…

A procedure for using Guilford's structure of the intellect as the theoretical basis for a task analysis model is presented. It is reasoned that such a model would furnish a bridge between task analysis and test selection, and also a bridge between test selection and test validation. Such a mechanism might answer some fo the EEOC criticisms of…

The problem of choosing educational and psychological tests to identify students with learning disabilities is discussed within a cost-efficiency framework. An efficiency index for estimating the classification accuracy of tests is presented and the use of expert judgment and the cost-effectiveness ratio is demonstrated with a numerical example.…

A model is described that was developed to train future learning disabilities specialists to select and execute diagnostic prescriptive strategies. A series of flowcharts depict the diagnostic-prescriptive model from point of referral, specifying steps for the process in language and readings. The sequence of tasks illustrate critical decisions…

The nationwide sales force (N=540) of a large food and beverage firm responded to a mail survey designed to investigate the role of value orientation as a moderator of the relationship between organizational rewards and job satisfaction. Of the two main elements in the investigation, the first was concerned with the predictive efficiency of two…

The data collected in higher education research are not always quantitative or continuous. Statistical methods using the log-linear model provide the institutional researcher with a powerful set of tools for addressing research questions when data are categorical. (Author/MSE)

Regression analysis is one of the most frequently used statistical techniques in institutional research. Principles of least squares, model building, residual analysis, influence statistics, and multi-collinearity are described and illustrated. (Author/MSE)

Path analysis and linear structural relations (LISREL) provide the institutional researcher with some extremely powerful statistical tools. However, they must be applied and interpreted carefully with a full understanding of their limitations and the statistical assumptions on which they are based. (Author)

Wechsler Intelligence Scale for Children, Revised (WISC-R) Verbal, Performance, and Full Scale IQ's were compared with Bannatyne recategorized WISC-R scores for groups of non-handicapped, educationally disadvantaged, learning disabled, and regular classroom Navajo Indian children. No definitive evidence was found to support the use of the…

A procedure for using Guilford's structure of the intellect as the theoretical basis for a task analysis model is presented. It is reasoned that such a model would furnish a bridge between task analysis and test selection, and also a bridge between test selection and test validation. Such a mechanism might answer some of the Equal Employment…

Accountability in vocational education is discussed as consisting of two subsystems, one providing data about developing new programs and the other as providing data for answering questions about the quality of existing programs. The Minnesota model for product evaluation, the latter subsystem, is discussed. It is predicated on the theory that…

The purpose for which a test is needed is the most important criterion for deciding which type of student assessment tool should be used. Standardized tests were developed as sorting instruments based upon certain views of knowledge and learning. Educators, according to their own values, must either bring standardized tests more into line with…
