The Effect Of Raters And Rating Conditions On The Reliability Of The Missionary Teaching Assessment, Abigail Christine Ure Dec 2010

The Effect Of Raters And Rating Conditions On The Reliability Of The Missionary Teaching Assessment, Abigail Christine Ure

Theses and Dissertations

This study investigated how 2 different rating conditions, the controlled rating condition (CRC) and the uncontrolled rating condition (URC), effected rater behavior and the reliability of a performance assessment (PA) known as the Missionary Teaching Assessment (MTA). The CRC gives raters the capability to manipulate (pause, rewind, fast-forward) video recordings of an examinee's performance as they rate while the URC does not give them this capability (i.e., the rater must watch the recording straight through without making any manipulations). Few studies have compared the effect of these two rating conditions on ratings. Ryan et al. (1995) analyzed the ...


Estimating Standard Errors Of Estimated Variance Components In Generalizability Theory Using Bootstrap Procedures, Joann Lynn Moore Dec 2010

Estimating Standard Errors Of Estimated Variance Components In Generalizability Theory Using Bootstrap Procedures, Joann Lynn Moore

Theses and Dissertations

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 for all combinations of conditions, and point estimates, standard error estimates, and coverage for three types of confidence intervals were calculated for each estimated variance component and relative and absolute error variance across a variety of bootstrap procedures for each combination of conditions. It was found that, with some exceptions, Tong and Brennan's (2007) rules ...
