Student Voices In Teacher Evaluation: A Multilevel, Latent Factor Investigation Of Teacher Quality, Kathleen J. Hoff
Student Voices In Teacher Evaluation: A Multilevel, Latent Factor Investigation Of Teacher Quality, Kathleen J. Hoff
Walden Dissertations and Doctoral Studies
Teacher effectiveness is a key driver of student achievement but persistently difficult to measure. Although precollege student surveys are one cost-effective alternative to traditional observation measures, little empirical research has been conducted on their factor structure. The purpose of this study was to investigate the validity of the Tripod Survey, a widely adopted precollege survey, as a measure of teacher effectiveness. The dataset was the Measures of Effective Teaching (Year 1, N = 1,024 Grade 9 classroom sections, 20,500 students; Year 2, N = 488 Grade 9 classroom sections, 8,658 students). The dynamic model of educational effectiveness guided the study. …

Examining The Performance Of The Metropolis-Hastings Robbins-Monro Algorithm In The Estimation Of Multilevel Multidimensional Irt Models, Bozhidar M. Bashkov
Dissertations, 2014-2019
The purpose of this study was to review the challenges that exist in the estimation of complex (multidimensional) models applied to complex (multilevel) data and to examine the performance of the recently developed Metropolis-Hastings Robbins-Monro (MH-RM) algorithm (Cai, 2010a, 2010b), designed to overcome these challenges and implemented in both commercial and open-source software programs. Unlike other methods, which either rely on high-dimensional numerical integration or approximation of the entire multidimensional response surface, MH-RM makes use of Fisher’s Identity to employ stochastic imputation (i.e., data augmentation) via the Metropolis-Hastings sampler and then apply the stochastic approximation method of Robbins and Monro …
