Investigating Active Learning Through The Lens Of Student Engagement, Nicole Naibert

Dissertations and Theses

Incorporating active learning into a course has been generally found to lead to improved student learning outcomes; however, not all students benefit from these environments to the same extent. Although active learning environments provide the opportunity for students to interact and engage with the material, whether a student decides to do so is completely up to them. Therefore, the goal of this dissertation was to begin exploring active learning environments through the lens of student engagement and relevant associated variables (i.e., self-efficacy and student perceptions). This was completed through three separate but related projects.

Project I focused on investigating flipped …

A Multiplicity Of Journeys: Stem Education Ecosystems As Sources Of Cultural Sustenance, Christopher Louis Beauprey Cardiel

Dissertations and Theses

In this document, I outline the context and significance of a research problem faced by both formal and informal science, technology, engineering, and math (STEM) educators in the Portland metro area--specifically, the need for greater understanding of the individual and cultural motivations, needs, and agentic behavior of learners, as well as the ways in which these factors intersect with learners' experiences of cultural sustenance within their holistic STEM education ecosystems. I base the significance of this problem on the racial and gender inequities evident in the STEM fields and the social and cultural dynamics that discourage members of these groups …

Amplifying Latinx Voice Through Interview Study: Highlighting Mathematics Identity As A Pathway To Student Self-Empowerment And Academic Agency, Brea Justine Cohen

Dissertations and Theses

Nationally, the percentage of high school students taking higher-level mathematics courses (beyond Algebra 2) has increased from the late 20th century to the present. However, as compared to White high school students enrolled in advanced math classes, the rate is lower among students of color, specifically students who identify as Latinx, African American, or Native American. My school district (a suburban district in the Northwestern United States) is working to address this problem by implementing several district-wide initiatives that focus on increasing students' engagement in mathematics, which focuses teacher pedagogy on leveraging mathematics communities to support collaborative mathematics dialogue. The …

Teacher Learning In The Context Of Students’ Mathematical Thinking, Mary Sherrett Duden

Dissertations and Theses

Currently mathematics education is undergoing substantial changes so that students may experience mathematics in intellectually engaging, equitable, and relevant ways. More specifically, I am referring to a teacher stance of centering student thinking and allowing students to make sense of mathematical ideas. Proponents of reform efforts in mathematics argue that this is the path to helping elementary students develop a deep and conceptually sound understanding of mathematics. This is critical because a strong mathematical foundation has increasingly become a gateway for access to many career opportunities and citizenship in the United States.

Unfortunately, these ambitious changes present a challenge for …

Next Generation Science Standards And Physics First: A Case Study Of High School Teachers' Beliefs And Practices, Stephen Godfrey Scannell

Dissertations and Theses

This dissertation is a case study of a school district in the Pacific Northwest that developed three-year high school science curricula using a Physics First course sequence (Physics, Chemistry, Biology), with the crosscutting concept Patterns as the central theme of the courses. The purpose of the study was to examine the impact of the implementation of the 9th grade course, Patterns Physics, on teacher practice and beliefs about science teaching and determine whether this new approach facilitated teacher classroom practices and beliefs congruent with those expressed in A Framework for K-12 Science Education (NRC, 2012) and the Next Generation Science …

An Examination Of The Relationship Between Professional Development Providers' Epistemological And Nature Of Science Beliefs And Their Professional Development Programs, Alfonso Garcia Arriola

Dissertations and Theses

In the last twenty years in US science education, professional development has emphasized the need to change science instruction from a direct instruction model to a more participatory and constructivist learning model. The result of these reform efforts has seen an increase in science education professional development that is focused on providing teaching strategies that promote inquiry learning to learn science content. Given these reform efforts and teacher responses to professional development, research seems to indicate that whether teachers actually change their practice may depend on the teachers' basic epistemological beliefs about the nature of science. The person who builds …

The Intermediate Value Theorem As A Starting Point For Inquiry-Oriented Advanced Calculus, Stephen Raymond Strand Ii

Dissertations and Theses

Making the transition from calculus to advanced calculus/real analysis can be challenging for undergraduate students. Part of this challenge lies in the shift in the focus of student activity, from a focus on algorithms and computational techniques to activities focused around definitions, theorems, and proofs. The goal of Realistic Mathematics Education (RME) is to support students in making this transition by building on and formalizing their informal knowledge. There are a growing number of projects in this vein at the undergraduate level, in the areas of abstract algebra (TAAFU: Larsen, 2013; Larsen & Lockwood, 2013), differential equations (IO-DE: Rasmussen & …

Teaching Mathematical Problem Solving In The Context Of Oregon's Educational Reform, Nicole R. Rigelman

Dissertations and Theses

Implementation of Oregon’s Educational Reform Act (HB 3565 and HB 2991) provides the context for this inquiry as its emphasis on problem solving has impacted mathematics teaching and learning throughout the state. Even though all Oregon teachers are responding to the same policy, their goals in teaching problem solving vary. These goals and these practices are influenced by the way teachers view the role of problem solving in the curriculum. Further, their practice is influenced by their knowledge and beliefs about mathematics content, teaching, learning, and the reform policy. The questions addressed in this study are: (1) What do exemplary …
