The Reliability Of Single-Item Assessments, Sijun Zhang
Legacy Theses & Dissertations (2009 - 2024)
Single-item assessments have become more popular recently in distinct areas, even though there is no consensus about whether they are sufficiently reliable. Researchers have developed methods to estimate the reliability of single-item assessments, some are based on factor analysis (method FA), correction for attenuation (method CA), and others employ Molenaar and Sijtsma’s theory (method MS), coefficient λ6 (method λ6), or latent class model (method LCRC). However, no empirical study has investigated which method estimates the reliability of single-item assessment most precisely. This study investigated this question via a simulation study. To represent assessments as found in practice, the simulation study …

Impact Of An Extended-Day Kindergarten Intervention On School-Related Variables : A Longitudinal Study, Catherine Bauer
Legacy Theses & Dissertations (2009 - 2024)
Increased awareness regarding the effectiveness of educational programs has been generated from recent legislative mandates. Given the significance of kindergarten as the foundation for academic learning, it is critical to evaluate whether district-created programs for entering students who are identified as at-risk are effectively meeting their needs. The current program evaluation study investigated the immediate and long-term effects of an extended-day intervention for kindergarten students identified as at-risk in one school district. Through archival data analysis, students who participated in the extended-day kindergarten (EDK; n=26) intervention beginning in the fall of 2000 and 2001 were compared with a control group …
