A Granular Account Of Student's Understanding Reasoning Within An Everyday And Scientific Contexts, Grace M. Gonnella Aug 2018

A Granular Account Of Student's Understanding Reasoning Within An Everyday And Scientific Contexts, Grace M. Gonnella

Electronic Theses and Dissertations

Teachers and educational researchers in the Maine Physical Sciences Partnership (Maine PSP) at the University of Maine identified making quality scientific arguments as a struggle for students. Not only is argumentation hard, but reasoning is the hardest component of an argument. Many frameworks have been developed to target teaching about argumentation but do not address how to teach one component of an argument in isolation. Educational practitioners encourage using everyday context to learn about arguments in the scientific context, but there is limited support in what is the best method. The first purpose of this research was to understand a …


School Climate: A Comparison Of Teachers, Students, And Parents, James A. Jacobs Aug 2018

School Climate: A Comparison Of Teachers, Students, And Parents, James A. Jacobs

Electronic Theses and Dissertations

This study was designed to examine the benefits of positive school climate and to measure the perceptions of school climate for intermediate grades in a Northeast Tennessee School district. An online school climate survey was used to collect responses from participants in intermediate grades and focused on the 3 major components of school climate: school engagement, school environment, and school safety. Data were collected for 2 consecutive years in 2016-2017 and 2017-2018. Response totals included 1,955 student responses, 116 teacher responses, and 210 parent responses that were analyzed and used for this study. Of the student totals, some students that …


Success Rates Of Second Semester Anatomy Students In Online And On-Ground Classes At A Community College In East Tennessee, William Sproat May 2018

Success Rates Of Second Semester Anatomy Students In Online And On-Ground Classes At A Community College In East Tennessee, William Sproat

Electronic Theses and Dissertations

Educators expect the number of institutions offering online courses and the number of students enrolling in these courses to increase as many students, particularly nontraditional students, discover the advantages of online content delivery. Online courses require new methods of communication between students and faculty as well as discovering new ways to build relationships, earn student trust, conduct appropriate assessment, and deliver useful course content. Many institutions—public, private, and for-profit—offer a wide variety of online coursework but faculty, employers, and the public have expressed concerns about the quality of online course content. In particular, online delivery of coursework in the natural …


Deciphering Climate-Driven Changes In Planktonic Diatom Communities In Lake Superior, Amy Kireta May 2018

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 …
