When scores are used to make decisions about respondents, it is of interest to estimate classification accuracy (CA), the probability of making a correct decision, and classification consistency (CC), the probability of making the same decision across two parallel administrations of the measure. Model-based estimates of CA and CC computed from the…

Proactive preliminary minimum sample size determination can be useful for the early planning stages of a latent variable modeling study to set a realistic scope, long before the model and population are finalized. This study examined existing methods and proposed a new method for proactive preliminary minimum sample size determination.

This study is a report on the design, development, and validation of a model within the main tenets of critical pedagogy (CP) with a hope to implement in education in general and applied linguistics in particular. To develop a transformative L2 materials preparation (TLMP) model, the researchers drew on Crawford's (1978) principles of CP as a…

This research paper explores the concept of "cost sharing" which became more prominent in Zambia education with the advent of democratic form of governance in 1991. As a way of responding to the ever diminishing tax revenues, government through the education policy of 1996, allowed higher education institutions including public…

Purpose: As computer-mediated communication has diffused, successive technological variations raise new questions about interpersonal impressions and several standardized instruments have been advanced in literature to asses various aspect of interpersonal attraction phenomena. The purpose of this paper is to examine the claims for reliability and…

This technical document provides guidance to educators on the creation and interpretation of survey instruments, particularly as they relate to an analysis of program implementation. Illustrative examples are drawn from a survey of educators related to the use of the easyCBM learning system. This document includes specific sections on…

Problem Statement: Transformational leadership increases organization members' commitment and engagement in meeting organizational goals and it enhances skills and capacities. Many studies reveal that transformational leadership behaviors, such as idealized influence, inspirational motivation, individualized consideration, innovative climate, and…

The aim of this study is to identify an ecological prediction model of bullying behaviors. Based on an ecological systems theory, this study identifies significant factors influencing bullying behaviors at different levels of middle and high school. These levels include the microsystem, mesosystem, exosystem, and macrosystem. More specifically,…

Sources of population heterogeneity may or may not be observed. If the sources of heterogeneity are observed (e.g., gender), the sample can be split into groups and the data analyzed with methods for multiple groups. If the sources of population heterogeneity are unobserved, the data can be analyzed with latent class models. Factor mixture models…

Considers a class of estimation procedures for the factor model. The procedures are shown to yield estimates possessing the same asymptotic sampling properties as those from estimation by maximum likelihood or generalized last squares, both special members of the class. General expressions for the derivatives needed for Newton-Raphson…

Authors attempted to measure a few key variables associated with the Porter-Lawler (1968) expectancy model in order to determine its validity. (Author/RK)

Two population raw data matrices were constructed by computer simulation techniques. Each consisted of 10,000 subjects and 12 variables, and each was constructed according to an underlying factorial model consisting of four major common factors, eight minor common factors, and 12 unique factors. The computer simulation techniques were employed to…

The empirical validity of the Biglan model of academic disciplines is supported. Examples are provided to illustrate how the systematic use of this model could enhance the quality of research on university faculty members and the academic administration of colleges. (Author/MLW)
