"Ain't I A Woman?": Black Women Negotiate And Resist Systemic Oppression In Undergraduate Engineering And Mathematics Disciplines, Jessica Alyce Wilson

Graduate Theses and Dissertations

In this inquiry I used Black Feminist Thought as the interpretive lens to investigate the characterizations and experiences of high achieving Black women undergraduate engineering and mathematics majors at a predominantly white institution. The qualitative inquiry considered intersecting oppressions to evaluate the experiences of this population. In particular, Black women operate in the intersection of race and gender, thus for a thorough analysis of their engineering and mathematics experiences to occur, the historical context of the United States and its oppressive structures must be considered. Stereotypes and systemic oppression follow this socially constructed identity as the participants enter the fields ...

Science Learning Opportunities And The Project Approach In Preschool Classrooms, Melissa Clucas Jan 2018

Science Learning Opportunities And The Project Approach In Preschool Classrooms, Melissa Clucas

Graduate Theses and Dissertations

Effective early science learning opportunities are critical for young children to build a solid foundation for subsequent development of concepts, as well as positive attitudes towards science (Eshach & Fried, 2005). However, these opportunities are often lacking in typical preschool classrooms (Connor, Morrison, & Slominski, 2006; Early et al., 2010). A multiple case study design was used to examine science learning opportunities in preschool classrooms using the Project Approach (PA; Helm & Katz, 2011). Guided by theoretical tenets from Dewey, Piaget, and Vygotsky, this study sought to explore the feasibility and efficacy of using the PA to promote high-quality science learning opportunities by examining the specific strategies teachers used to plan for authentic and meaningful experiences, structure the environment ...

How Teachers’ Beliefs About Climate Change Influence Their Instruction, Student Understanding, And Willingness To Take Action., Molly Trendell Nation Jul 2017

How Teachers’ Beliefs About Climate Change Influence Their Instruction, Student Understanding, And Willingness To Take Action., Molly Trendell Nation

Graduate Theses and Dissertations

Climate change science is complex and controversial in nature, yet seen by educators and policy makers as an important topic to be taught within secondary science education. This is becoming increasingly evident with the inclusion of climate change into the Next Generation Science Standards (NGSS) for Earth and Space Sciences as well as Life Science courses (NGSS, 2013). An overwhelming amount of information is available to students; however, it is often misrepresented, politically inflated and falsified, and littered with misconceptions (Dawson & Carson, 2014; Gayford, 2002). It is critical to engage students in discourse that challenges them ethically in order for students to ...


Prevalence Of Typical Images In High School Geometry Textbooks, Megan N. Cannon Jun 2017

Prevalence Of Typical Images In High School Geometry Textbooks, Megan N. Cannon

Graduate Theses and Dissertations

Visualization in mathematics can be discussed in many ways; it is a broad term that references physical visualization objects as well as the process in which we picture images and manipulate them in our minds. Research suggests that visualization can be a powerful tool in mathematics for intuitive understanding, providing and/or supporting proof and reasoning, and assisting in comprehension. The literature also reveals some difficulties related to the use of visualization, particularly how illustrations can mislead students if they are not comfortable seeing concepts represented in varied ways. However, despite the extensive research on the benefits and challenges of ...

Science In The Sun: How Science Is Performed As A Spatial Practice, Natalie Kass

Graduate Theses and Dissertations

This study analyzes how spatial organization impacts science communication at the St. Petersburg Science Festival in Florida. Through map analysis, qualitative interviews, and a close reading of evaluation reports, the author determines that sponsorship, logistics, exhibitor ambience, and map usability and design are the factors most affecting the spatial performance of science. To mitigate their effects, technical communicators can identify these factors and provide the necessary revisions when considering how science is communicated to the public.


Exploring Mathematics Teacher Education Fieldwork Experiences Through Storytelling, Melody Jeane Elrod Feb 2017

Exploring Mathematics Teacher Education Fieldwork Experiences Through Storytelling, Melody Jeane Elrod

Graduate Theses and Dissertations

Throughout the history of teacher education, the final fieldwork experience has often been called the single most influential experience in teacher preparation programs (Burns, Jacobs, & Yendol-Hoppey, 2016; Feiman-Nemser & Buchmann, 1986; Parker-Katz & Bay, 2008). Though this experience has been expanded to include fieldwork experiences throughout many teacher education programs (Guyton & McIntyre, 1990), the final fieldwork experience remains the closing activity and the lasting image of teacher preparation (Feiman-Nemser & Buchmann, 1986; Rosaen & Florio-Ruane, 2008). Given its importance, though, researchers know relatively little about it. “The knowledge thus produced is akin to the quantum theory of physics; we know what goes in . . . and what comes out . . . but not what occurs in the interim” (Guyton & McIntyre, 1990, p. 524). Given the current reforms in mathematics education and mathematics teacher education (National Council for the Accreditation of Teacher Education, 2010; National Governors Association Center for Best Practices & Council of Chief State School Officers, 2010), Guyton and McIntyre’s observation is still relevant today.

During the final fieldwork experience, university-based and school-based mathematics educators must work together on behalf of the novice to marry university-promoted theory (especially reform-oriented theory) with the practical classroom expectations of day-to-day teaching life. Though there is much research on how this kind of work should be done and the dilemmas that have arisen during fieldwork (e.g., Knight, 2009; Loughran, 2006; Nolan & Hoover, 2004; Sergiovanni & Starratt, 2006; Sullivan & Glanz, 2013), we have little information about the experiences of the mathematics educators who collaborate during final fieldwork. Furthermore, we have very little information on how these educators navigate mathematics reforms to prepare teachers of mathematics.

This multi-case study was designed to investigate ...


Distributed Leadership For Equity And Excellence In Mathematics: An Elementary School Case Study, Comfort Enono Akwaji-Anderson Jan 2017

Distributed Leadership For Equity And Excellence In Mathematics: An Elementary School Case Study, Comfort Enono Akwaji-Anderson

Graduate Theses and Dissertations

The need for schools to develop and implement actions that will clearly improve the academic performance of all children is of great importance. Schools face pressure to improve K-12 mathematics instruction to reach all students, regardless of economic, linguistic, or cultural background (NCSM, 2008, 2016). Supporting academic excellence and equity in school mathematics requires strong leadership (Blankstein & Noguera, 2015). Recognizing that leadership in a school does not fall on the shoulders of just one person (Spillane & Healey, 2010, p. 256), the purpose of this case study was to explore the “how” of leadership, specifically the leadership practices that get us to the “why” (e.g., equity) and “what” (e.g., leadership for excellence) of mathematics education. The overarching question driving this research was: “What are the leadership practices that are intended to promote equity and excellence in mathematics education?” Using Spillane, Halverson, & Diamond’s Distributed Leadership Perspective (2004), the goal was to understand the respective distributed roles teachers and other individuals took in the process of achieving equity and excellence in mathematics at one elementary school. Formal (e.g., Head of School, Central Office Administrator) and Informal (e.g., teachers and parents) leaders were interviewed and observed. Data analysis focused on identifying the macro-functions (e.g., overall leadership practices) and micro-tasks (e.g., day-to-day, short-term tasks) that leaders engaged in to promote equity and excellence. Leadership practices were focused in three areas: Supporting the Teaching/Learning of all Students; Supporting the Teaching of Diverse Students; and Parent/Family Connection. Five primary categories of leadership practices were identified: Relationship, Instruction Support, School Climate, and Parent Involvement.

Despite the importance of family engagement, teachers faced challenges communicating to parents, getting them to help with ...

A Longitudinal Examination Of A Ssi-Embedded Experiential Environmental Education Course And Environmental Behaviors, Mark H. Newton

Graduate Theses and Dissertations

A perennial goal of environmental education is to produce a scientifically literate citizenry capable of negotiating and resulting complex environmental problems. Popular methods of environmental education instruction tend to overemphasize scientific content knowledge and neglect to consider ethical and moral aspects of the problem. This qualitative study examines the longitudinal association between an experiential environmental education course infused with SSI instruction and students’ environmental behaviors. The results indicate that several students’ conceptualizations of contentious environmental issues change after completing the course and specifically. Furthermore, students’ willingness to act to resolve contentious environmental issues was most closely associated with their environmental ...

The Influence Of Types Of Homework On Opportunity To Learn And Students' Mathematics Achievement: Examples From The University Of Chicago School Mathematics Project, Yiting Yu Sep 2015

The Influence Of Types Of Homework On Opportunity To Learn And Students' Mathematics Achievement: Examples From The University Of Chicago School Mathematics Project, Yiting Yu

Graduate Theses and Dissertations

ABSTRACT

Public views on assigning students mathematics homework have been controversial. Although homework is designed for students to complete during non-school hours (Cooper, 1989), many see homework as excessive pressure on students. Most research placed their focus on the influence of the time spent on homework or the amount of homework on student achievement. Few studies have addressed the impact of types of mathematics homework. The purpose of this study is to examine the role of homework types in influencing opportunity to learn (OTL) on student achievement.

This quantitative study used subsets of a large existing dataset collected by University ...
