The COVID-19 pandemic's impact on preschool children's school readiness skills remains understudied. This research investigates Head Start preschool children's early numeracy, literacy, and executive function outcomes during a pandemic-affected school year, using a novel virtual assessment methodology. Study children (N = 336; mean age = 51…

The Student Growth Objectives are assessments created locally or by commercial educational organizations. The students' scores from the Student Growth Objectives are included in teacher summative evaluation as one of the measures of teacher's effectiveness. The high amplitude of the requirements in teacher evaluation raised a concern of whether…

The purpose of this causal-comparative study is to examine the impact of Troops to Teachers (TTT) participants on student achievement by comparing the mean scores of Texas students in the eighth grade during the 2011-2012 academic year taught by TTT participants with the mean scores of all other Texas eighth grade students on each of four…

To provide a more in-depth analysis of the potential academic impacts of the School District of Philadelphia's proposed school closure plan, Research for Action (RFA) compared 32 schools…

Despite the prevalence of student learning objectives (SLOs) in teacher evaluation systems throughout the United States, research on the validity of student and teacher SLO scores used for high-stakes decisions is lacking. For this reason, this dissertation is comprised of two chapters that examine student and teacher-level SLO performance data…

Use of multivariate analysis (e.g., multivariate analysis of variance) is common when normally distributed outcomes are collected in intervention research. However, when mixed responses--a set of normal and binary outcomes--are collected, standard multivariate analyses are no longer suitable. While mixed responses are often obtained in…
