This dissertation comprises three complementary studies that aim to advance the understanding and practice of Individualized Education Programs (IEP) and Present Levels of Academic Achievement and Functional Performance (PLAAFP) development in special education. In the first study, we systematically reviewed empirical research measuring IEP…

This dissertation consists of three studies which examined multidimensional balance in youth (= 21 years; Individuals with Disabilities Education Act, 2004) with visual impairments (VIs) using the Brief-Balance Evaluation Systems Test (Brief-BESTest). These studies have the potential to inform (adapted) physical education curricula and…

Subscores, also known as domain scores, diagnostic scores, or trait scores, can help determine test-takers' relative strengths and weaknesses and appropriately focus remediation. However, subscores often have poor psychometric properties, particularly reliability and distinctiveness (Folske, Gessaroli, & Swanson, 1999; Monaghan, 2006;…

The review of current supervision models and instruments revealed a crucial need for a valid, reliable instrument that assesses the quality of the supervision environment as a venue for promoting counselor development. Therefore, the primary purpose of this study was the construction and initial validation of the Chae Optimal Supervision…

This study examines the proposed Reliability Generalization (RG) method for studying reliability. RG employs the application of meta-analytic techniques similar to those used in validity generalization studies to examine reliability coefficients. This study explains why RG does not provide a proper research method for the study of reliability,…

There are a large number of students entering college underprepared for college-level mathematics (Carnegie Foundation for the Advancement of Teaching, 2011). While this problem is not new, it has become the focus of national attention because of the impact it has on college completion and workforce development. There is much written in the…

This study compares the dependability of four classroom assessment scoring methods. Generalizability theory (G) and alternative decision (D) are used to measure the results of students' classroom assessment scores and compare the results of the four scoring methods on variability of rater by person variance and the level of G and D coefficients…

Research indicates that many elementary students do not comprehend that the equal sign is an indication that an equality relation exists between two structures. Instead, they perceive the equal sign as an indication that a particular procedure is to be performed. As students mature, and as their exposure to the equal sign and equality relations in…

This study evaluated the reliability, validity, and educational usefulness of a comprehensive, multidisciplinary Objective Structured Clinical Examination (OSCE) in dental education. The OSCE was administered to dental students at the Columbia University College of Dental Medicine (CDM) before they entered clinical training. Participants in this…

Research shows that adolescents enter a circadian-phase delay as they approach and enter high school. On or about age 14, teens become less of a morning learner due to biological factors. Researchers have determined consequences to the adolescent's circadian shift as related to learning; therefore, morning time may have a negative influence on the…

Classrooms are a primary site of evidence about learning. Yet classroom proceedings often occur behind closed doors and hence evidence of student learning is observable only to the classroom teacher. The informal and undocumented nature of this information means that it is rarely included in statistical models or quantifiable analyses. This…
