An Investigation Of The Instructional Norms Of Mathematical Communication When Students Present Geometry Proofs At The Board, Bukola T. Ake

Electronic Theses and Dissertations

Expert mathematical communication is a synthesis of speaking, writing, diagramming, and gesturing. What opportunities are there for secondary mathematics students to learn the discipline-specific ways in which these modalities can be combined to communicate proofs? In an initial effort to investigate this question, Dimmel and Herbst (2020) conducted a multimedia survey experiment to test a hypothesis about how secondary mathematics teachers expect students to communicate when presenting proofs at the board in secondary geometry classrooms. Their hypothesis, based on an analysis of episodes of instruction from a small sample of secondary geometry classrooms, was that teachers expected student presentations of …

Work At The Boundary: A Research-Practice Partnership To Integrate Computer Science Into Middle School Science, Amelia R. Callahan

Electronic Theses and Dissertations

The Maine Center for Research in STEM Education (RiSE Center) is currently developing a partnership between university education researchers, computer science faculty, and middle school science teachers throughout the state. The goal of this partnership is to develop a set of lessons that integrate computer science concepts and practices into existing science curricular materials. This STEM+C partnership brings together individuals who have a wide range of experience and comfort with computer science and teaching middle school. This study focuses on the partnership’s early stages through its initial summer collaborations. We designed and administered interviews prior to the module design process …

The Correlation Between The Act, Inc. Explore Test And Student Success In High School Advanced And Advanced Placement Mathematics Courses, Virginia Story

Electronic Theses and Dissertations

The purpose of this study was to compare the relationship between the mathematics portion of the EXPLORE test with students successes in advanced and Advanced Placement(AP) mathematics courses in high school. The data was collected from a rural Tennessee school system consisting of five years of data among graduated seniors. Analysis was completed to determine the difference between the two county high schools in advanced coursework. The findings of this study concluded a positive correlation between EXPLORE scores and the frequency of students who took advanced mathematics courses. Positive correlation between EXPLORE scores and student successes in advanced courses was …

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 …

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 …

Instructional Teacher Job Resources And Student Achievement In Mathematics., Amy Stokes-Levine

Electronic Theses and Dissertations

Research shows that teachers who are supported with job resources are more engaged regardless of the level of demands (Klusmann et al., 2008). Additionally, teachers who are engaged with their work are less likely to report their intention to leave the teaching profession (Klassen et al., 2012), which is particularly important for mathematics teachers who are in high demand (Sutcher, Darling-Hammond, & Carver-Thomas, 2016). Supporting employees with job resources is a commonly accepted practice in many professional fields (e.g., Christian, Garza, & Slaughter, 2011), yet is not a common practice in education (e.g., Bidwell, 2013; Gewertz, 2014; Layton, 2015; Rentner …

Discussion In Middle And High School Earth Science Classrooms And Its Impact On Students' Abilities To Construct Evidence-Based Arguments In Their Written Work, Rachel Martin

Electronic Theses and Dissertations

Middle and high school teachers who participate in the Maine Physical Sciences Partnership (MainePSP) noted persistent problems in their classrooms, including low levels of student engagement and gaps in how students use evidence. To address these problems, this study was designed in collaboration with MainePSP teachers in a design-based implementation research process as teachers aimed to better connect classroom discussion and written argumentation. Though scientific writing makes use of argumentation to support ideas, it is often the sharing of ideas that makes an argument stronger.

Two teachers collected data from their seventh and ninth grade Earth Science classrooms at schools …

Northeast Tennessee Educators’ Perception Of Stem Education Implementation, Kristin Turner

Electronic Theses and Dissertations

A quantitative nonexperimental survey study was developed to investigate Northeast Tennessee K-8 educators’ perceptions of STEM education. This study was an examination of current perceptions of STEM education. Perceived need, current implementation practices, access to STEM resources, definition of STEM, and the current condition of STEM in Northeast Tennessee were also examined. The participating school districts are located in the Northeast Region of Tennessee: Bristol City Schools, Hamblen County Schools, Johnson City Schools, Johnson County Schools, Kingsport City Schools, Sullivan County Schools, and Washington County Schools. Educational professionals including both administrators and teachers in the elementary and/or middle school setting …

Inquiry, Efficacy, And Science Education, Heather Christa Scott

Electronic Theses and Dissertations

Developing learners who are equipped to think critically about the vast information circulating around them is essential in their preparation for a role in society today. The use of effective inquiry-based instruction is not a widespread practice among K-12 classrooms. Many secondary and post-secondary science instructors see the valuable link between students asking questions and the development of critical thinking. Inquiry-based instruction provides student opportunities to ask questions, design methods of investigation, gather information, and finally reach conclusions based on evidence. However, this instruction style is rarely used in the classroom, particularly in elementary classrooms. This study examines the relationships …
