The Kaufman Brief Intelligence Test (K-BIT) was used as a screening instrument to predict Wechsler Intelligence Scale for Children-Third Edition (WISC-III) scores of 94 students referred for psychoeducational evaluations. Although the correlation coefficient between the K-BIT IQ Composite and the WISC-III Full Scale IQ was 0.771 for the entire…

Since canonical correlation analysis subsumes multiple regression as a special case, and since commonality analysis (a variance partitioning procedure) has proven useful in interpreting multiple regression results, the interpretation of canonical correlation results might also be enhanced by the use of commonality analysis. In this paper, a…

Even though Swedish students (age 9 and 14 years) placed third in the recent IEA study, reading instruction in Swedish schools is apparently no better than in other countries taking part in the IEA study. No strong correlations between type of reading instruction and students' reading skills have been found. Schools in Nordic countries work under…

The power of the procedure of W. Stout to detect deviations from essential unidimensionality in two-dimensional data was investigated for minor, moderate, and large deviations from unidimensionality using criteria for deviations from unidimensionality based on prior research. Test lengths of 20 and 40 items and sample sizes of 700 and 1,500 were…

The need for using invariance procedures to establish the external validity or generalizability of statistical results has been well documented. Invariance analysis is a tool that can be used to establish confidence in the replicability of research findings. Several approaches to invariance analysis are available that are broadly applicable across…

The first purpose of this study was to investigate the stability of two essential dimensionality measures across 10 random samples within a particular assessment item (AT1) selection. Other purposes were to investigate the discrepancy of the essential unidimensionality estimates for a test across different AT1 selections and sample sizes and to…

A multi-method approach to the diagnosis of attention deficit hyperactivity disorder was investigated for the purpose of developing an assessment model that could detect the subjects' level of functioning within Mirsky's (1987) four phases of attention and to determine if the primary distractors were by auditory, visual, or combined stimuli.…

Cognitive style indicates how a learner thinks and responds to the environment. Cognitive styles of education majors appear to have an impact on performance in preservice education coursework. This study classifies as field dependent or field independent the cognitive styles of 537 education majors at Auburn University (Montgomery, Alabama) and…

The Pearson product moment (P.M.) correlation ("r") and four of its most widely used variations--the phi, the rho, the biserial, and the point-biserial coefficients--are reviewed. Using small data sets between one and nine, the conditions under which the various forms are restricted in power and robustness are explored. Seven sample data…

The purpose of this study was to examine the relationship of balance and bilateral coordination to the fundamental locomotor pattern of skipping in 5- and 6-year old children. Subjects were kindergarten students (N=30) who were attending an elementary school in the suburban Kansas City area. The investigators used items from the…

A study investigated what can be learned about the strengths and weaknesses of students' writing from direct assessment of writing performance and knowledge of overall student performance. In the first part of the study, all 13 school districts in Alaska participated in an interdistrict writing assessment procedure intended to measure the overall…

Performance in assessing the unidimensionality of tests was examined for four methods: (1) W. F. Stout's procedure (1987); (2) the approach of P. W. Holland and P. R. Rosenbaum (1986); (3) linear factor analysis; and (4) non-linear factor analysis. Each method was examined and compared with the others using simulated and real test data. Seven data…

Pupils from fourth, fifth, and sixth grades (N=198) were studied to determine the relationship between children's self-concept, academic achievement, and teacher's rating of children's self-concept. The differences between grade levels, sex, and ethnic group membership were tested by analysis of variance. Results are discussed. (Author)

The findings from a study of 117 students support the view of educators who rely on the NLN achievement test scores to predict student performance in State board examinations. (Author/BP)

Assessment is one of the crucial components of the instruction. People within the educational community, i.e. policymakers, educators, students, parents, administrators, have different ideas regarding the implementation of assessment strategies (Dietel, Herman, and Knuth, 1991). While some believe traditional assessment methods are more effective,…
