This article is aimed to investigating the influence of a web quest strategy on achievement, and whether collaborative learning can maximize the effectiveness of a web quest used as a medium in teaching and learning educational psychology among the female students at Al Majmaa University in...

Am Übergang von der Schule in den Beruf werden wichtige Weichen gestellt, die den weiteren Lebenslauf eines Menschen vorbereiten. Dazu werden in diesem Band neue Ergebnisse der vielfältigen Transitionsforschung aus der ganzen Schweiz vorgestellt, die sich an verschiedenen Disziplinen wie der...

The purpose of this study was to investigate the performance of the parametric bootstrap method and to compare the parametric and nonparametric bootstrap methods for estimating the standard error of equating (SEE) under the common-item nonequivalent groups (CINEG) design with the frequency...

Broadening the term augmented testing to include a combination of multiple measures to assess examinee performance on a single construct, the issues of IRT item parameter and proficiency estimates were investigated. The intent of this dissertation is to determine if different IRT calibration...

This study investigated the extent to which rules proposed by Tong and Brennan (2007) for estimating standard errors of estimated variance components held up across a variety of G theory designs, variance component structures, sample size patterns, and data types. Simulated data was generated...

This dissertation investigates the interaction of population invariance, equating assumptions, and equating accuracy with group differences. In addition, matched samples equating methods are considered as a possible way to improve equating accuracy with large group differences.Data from one...

The measurement of achievement growth raises many challenges, including how to define "growth" and select or develop a growth measure that captures that definition. Despite these complications, current federal educational policies focus on student growth measures for accountability purposes....

Smoothing techniques are designed to improve the accuracy of equating functions. The main purpose of this dissertation was to propose a new statistic (CS) and compare it to existing model selection strategies in selecting smoothing parameters for polynomial loglinear presmoothing (C) and cubic...

As item response theory (IRT) has developed and is widely applied, investigating the fit of a parametric model becomes an important part of the measurement process when implementing IRT. The usefulness and successes of IRT applications rely heavily on the extent to which the model reflects the...

Needle sharing contributes to the spread of the human immunodeficiency virus and other health concerns and remains a persistent problem among injection drug users. We determined whether needle sharing may be related to the discounting of the value of delayed outcomes. Outpatients in treatment...
