Differential item functioning (DIF) analysis is a key component in the evaluation of the fairness and validity of educational tests. The goal of this project was to review the status of ETS DIF analysis procedures, focusing on three aspects: (a) the nature and stringency of the statistical rules used to flag items, (b) the minimum sample size…

This study reports on the continued large-sample validation of the Inventory for Teaching and Learning (ITAL), a new teacher perception measure of "reformed (inquiry- and standards-based) and traditional teaching and learning" developed for use in science and mathematics classrooms. The continued validation of the ITAL used large samples…

In large-scale assessments, such as the National Assessment of Educational Progress (NAEP), plausible values based on Multiple Imputations (MI) have been used to estimate population characteristics for latent constructs under complex sample designs. Mislevy (1991) derived a closed-form analytic solution for a fixed-effect model in creating…

The purpose of this study is to develop an estimate of Adequate Yearly Progress (AYP) that will allow for reliable and valid comparisons among student subgroups, schools, and districts. A shrinkage-type estimator of AYP using the Bayesian framework is described. Using simulated data, the performance of the Bayes estimator will be compared to…

Optometry school admissions are very competitive. With more applicants than available slots, admission committees must choose those students whom they feel will be successful graduates. Previous studies in the health profession schools have demonstrated that the predictors of academic achievement are preadmission science grade point average (GPA),…

The aim of this study is to determine the magnitude of cognitive dissonance present in a sample of female students at Umm Al Qura University, and clarifying the relationship between the cognitive dissonance and decision-making styles. It also aimed to identify differences between female students with high cognitive dissonance and those with low…

Growth mixture modeling (GMM) has become a more popular statistical method for modeling population heterogeneity in longitudinal data, but the performance characteristics of GMM enumeration indexes in correctly identifying heterogeneous growth trajectories are largely unknown. Few empirical studies have addressed this issue. This study considered…

To help increase the effectiveness of self-directed teams, this paper studies the attitudes and behaviour of self-directed team members during the course of a computer simulated marketing strategy game. Self-directed teams are used widely throughout organisations yet receive little scrutiny when they undertake a task which is subject to conditions…

The evolution from static to dynamic electronic learning environments has stimulated the research on adaptive item sequencing. A prerequisite for adaptive item sequencing, in which the difficulty of the item is constantly matched to the ability level of the learner, is to have items with a known difficulty level. The difficulty level can be…

In this study, a content analysis of research is aimed in the field of mathematics education of Turkish researchers. To this aim, the investigation of 359 article were made which were accessed from web in full text between 1987 and 2009 years and which were published in the field of mathematics education from 32 different journals. 27 of these…

The authors investigated whether confidence in causal judgments varies with virtual sample size--the frequency of cases in which the outcome is (a) absent before the introduction of a generative cause or (b) present before the introduction of a preventive cause. Participants were asked to evaluate the influence of various candidate causes on an…

This document represents one of three appendices associated with "The Nation's Report Card: A First Look--2013 Mathematics and Reading. National Assessment of Educational Progress at Grade 4 and 8. NCES 2014-451." It includes tabular data relating to the mathematics portion of the National Assessment of Education Progress at Grade 4 and…

This paper reports insights into the nature and practices of inclusive schools in India using a case study methodology. Being a signatory of the Salamanca Statement, the Government of India has undertaken to implement an inclusive system of education in schools. An initial survey conducted to identify sample inclusive schools showed that inclusive…

With the increasing enrollment of international students in North American universities, the need to support the adjustment of international students has also increased. One factor consistently identified as essential to successful student adjustment is having a strong support network, including familial support. Previous research investigating…

Studies have shown that many information technology (IT) projects achieve success, while many more do not. Further, researchers have identified various causes of this problem and have suggested remedies. However, these studies have not focused on the nature of the relationship between trust and success in IT projects. Consequently, this study…
