The degree to which public school superintendents and public school systems are being held accountable has increased in recent years. The recent unethical decisions made within the last decade in both the public and private…

This mixed method study explored three approaches to reading fluency and their impact on students' reading fluency, perceived reading efficacy, and engagement. The quantitative portion of the study was conducted with 182 second-grade students and was guided by the following questions: (a) Which instructional method, iPod Touch, student-pairing, or…

This dissertation research describes an investigation that explores the nature of the relationship between participation in evaluation and the use of evaluation findings and processes within three large-scale multisite evaluations. The purpose of this study is to test whether assumptions and theories about participation translate into evaluation…

Brazilian Portuguese (henceforth BP) has for long been considered as a Null-subject language due to its variability in regards to subject expression (e.g. "Era bom porque eu diminuia de peso...era muito gordinha" "That was good because then I could lose some weight...(I) was a bit chubby." C33:179). Such variability has been…

This mixed method study explored and analyzed instructional strategies utilized by algebra teachers whose students' coursework culminated in the New York State Regents Examination in Integrated Algebra and for whom 50% of the tested cohort earned mastery level (85 or higher) on the examination. The targeted populations were eighth or ninth grade…

The purpose of this study was to create a valid and reliable instrument to measure teacher perceived barriers to the adoption of games and simulations in instruction. Previous research, interviews with educators, a focus group, an expert review, and a think aloud protocol were used to design a survey instrument. After finalization, the survey was…

This dissertation uses a case-sensitive approach to examine an active travel intervention's diverse target population. It builds on a series of travel choice models, and draws key conceptual themes from Chapin's (1974) human activity model, which highlights opportunity-related and propensity-related factors associated with behaviors. The research…

Many college students struggle with first-semester general chemistry. Prior studies have shown that a student's prior knowledge of chemistry, a cognitive factor, does not account for the total variance when measured by examination scores. This study explored the role of self-regulated learning (SRL) to identify the degree of success or failure of…
