Teacher Judgment Accuracy In The Domain Of Spelling, April Spencer

Electronic Theses and Dissertations

This study investigated first and second grade teachers’ understanding of their students’ skill in spelling words of varying difficulty. Specifically, teachers judged their students’ item- by-item performance on a twelve-item spelling test adapted from a commercially available developmental spelling inventory. Results showed that teachers’ judgments were accurate 77% of the time, a figure similar to accuracy levels reported in previous teacher judgment research in the area of literacy. The study also included an error analysis task that was designed to assess teachers’ knowledge of developmental spelling. Results revealed a significant relationship (r = .42) between teacher judgment accuracy and performance …

Teacher Performance Evaluation And Professional Growth In The Era Of "Educator Effectiveness" In Maine, Jonathan E. Doty

Electronic Theses and Dissertations

Maine is one of many states that undertook reform to teacher supervision and evaluation in the wake of public attention (e.g., Waiting for Superman) and federal pressure (e.g., NCLB Flexibility Waivers). The Maine Legislature passed An Act to Ensure Effective Teaching and School Leadership (2012), shifting from local discretion to greater state influence on the functions of formative supervision and summative evaluation. As school districts created systems to meet the state’s mandates, they combined growth and employment functions and navigated persistent challenges described in the literature on evaluation and supervision.

The purpose of this study was to examine perspectives …

A Multiple Case Study Of Secondary School Teachers' Understanding Of Learning Relationships In Virtual Schools: Implications For Teacher Identity, Linda M. Fuller

Electronic Theses and Dissertations

There is now a strong presence of virtual schools in the United States serving K-12 students, along with increased opportunities for brick-and-mortar students to take virtual courses (Ash, 2011; Luo, Hibbard, Franklin, & Moore, 2017). Research into the human impact of virtual education is not keeping pace (Gulosino & Miron, 2017; Rice et al., 2014). This study focused on the experiences and insights of virtual teachers in terms of their relationships with learners as well as on potential changes in their sense of professional identity as they moved from one setting to the other. During a series of three individual, …

Deciphering Climate-Driven Changes In Planktonic Diatom Communities In Lake Superior, Amy Kireta

Electronic Theses and Dissertations

Climate change is affecting lake systems throughout the world, including Lake Superior, the world’s largest lake by surface area. Climate-driven physical changes in Lake Superior are well documented, but there is still substantial uncertainty of how recent biological changes are related to climate change. This research addresses these uncertainties using a variety of approaches to understand the effects of modern climate-driven changes on Lake Superior diatom communities. First, I developed models for environmental variables related to diatom abundance using 10 years of summer monitoring data. Second, I investigated changes in fossilized diatom relative abundances before, during, and after the Medieval …
