Thesis advisor: Henry I. Braun / With teachers being largely held accountable for student learning outcomes, it is of critical importance to identify effective and ineffective teachers through the development and implementation of a successful teacher evaluation system. Addressing the call to explore indicators of teacher effectiveness and enhance the traditional methods and practices of teacher evaluation, this study extends current efforts investigating different approaches to measuring teacher effectiveness through exploration of the relationship between two indicators of teacher effectiveness: the value-added estimates based on student test performance and growth, and the quality of student learning objectives (SLO) developed by teachers. It uses data from a large school district in North Carolina, comprising student achievement outcomes in mathematics and reading across five grades and three years. Different hierarchical linear models are employed to obtain teachers' VAM estimates with regression adjustments for prior years of achievement, student background characteristics, and teacher level covariate adjusted for each set of models. Weighted Least Squares (WLS) analysis, logistic regression, and point-biserial analysis are used to examine the variations in the relationships among teachers' VAM estimates, SLO quality and SLO attainment status across years and grades. The HLM results revealed fluctuations in teachers' VAM rankings obtained at different stages of the model sequence that caused the correlations with SLO quality to vary as well. The WLS results indicated that the correlations between VAM and SLO quality also varied across years and grades. Further data analysis revealed generally weak associations between SLO quality and attainment status, as well as those between teachers' VAM estimates and whether their SLOs were achieved. / Thesis (PhD) — Boston College, 2015. / Submitted to: Boston College.
