The thesis of this paper is that the decision to use one of three approaches to unit-of-analysis in educational research should be based on substantive considerations, not statistical factors. In addition to the commonly used "total analysis" (regression analysis across individuals), the within and between analyses are inherent in the…

Factor analyses of the Wechsler Intelligence Scale for Children-Revised (WISC-R) have typically yielded three factors: two generally understood to reflect basic verbal and performance dimensions and one about which there is no consensus with regard to what is measured. The aim of the present study is to elaborate the meaning of the third factor by…

The relationships between a diverse set of individual difference, demographic, and aptitude variables; and a set of student attitudes and behaviors pertinent to experiences in large lecture classes were examined. The sample was 4300 students enrolled in 33 lecture classes at a large university. The relationship between the set of individual…

A research project was designed and conducted to determine specifically whether the Graduate Management Admission Test (GMAT) has any predictive value in determining how well masters of business administration (MBA) students perform in graduate management education. Several types of information were drawn from the student files of 360 past or…

To assess the effects of correlated abilities on test characteristics, and to explore the effects of correlated abilities on the use of a multidimensional item response theory model which does not explicitly account for such a correlation, two tests were constructed. One had two relatively unidimensional subsets of items, the other had all…

The focus of this study was to explore the relationship between culture and children's development, and to suggest that inquiry into narratives is a way of understanding how children live and develop in a cultural sense. The article begins by inquiring into the nature of culture in the Hong Kong context and explaining the ways in which it might…

Four epistemological belief and two teaching/learning conception dimensions were identified from a questionnaire study of a sample of Hong Kong preservice teacher education students. The epistemological belief dimensions were labelled Innate/Fixed Ability, Learning Effort/Process, Authority/Expert Knowledge and Certainty Knowledge. The somewhat…

This study examines how students' cognitive styles are correlated with their attitudes toward online education and learning behaviors in online learning environments. The Group Embedded Figures Test (GEFT) and the attitude survey toward online instruction were administered to 104 students enrolled in various online courses at the University of…

A canonical correlation model was applied to data on 36 primary level classes for educable mentally retarded students to determine whether classroom means and standard deviations on a criterion variable were predictable from classroom means and standard deviations on input measures. (Author/MC)

The Specific Language Disability Test developed by Neva Malcomesius was administered to 195 regular sixth grade students for the purposes of standardization and correlation with achievement and intelligence test scores. (DB)

A method of estimating the operating characteristics of a new test item added to an established test without assuming a prior model has been proposed by the author. In this paper, the author extends this logic by proposing a different hypothesized distribution of the resulting estimate. The former method used a normal approximation; the present…

The pretest-posttest design referred to as Design 2 by Campbell and Stanley (1963) is commonly used in educational research and evaluation. The tenability of the assumption of a zero population difference commonly used with this design is questioned. A nonzero population estimate based on the mean difference observed in test-retest reliability…

Four sections of introductory psychology were involved in a study of aptitude-treatment interactions. Two sections were taught with a high-structure curriculum, and two with a low-structure curriculum. Students' preference for structure was measured with the Inventory of Beliefs (IOB). During eight weeks of instruction, observers recorded…

Good and poor readers from grades 2 to 5 were compared on conceputal style preference, cognitive tempos and attentional styles. Attentional style measures distinguished poor and good readers better than the other cognitive style measures. (Author/BJG)
