Instructors At A Crossroad: Perceptions Of Collaboration And Support Intersect With Intentions To Implement A Cure, Justin Berl

Dissertations and Theses

An ongoing crisis of student drop-off from undergraduate science, technology, engineering and mathematics (STEM) education has led to a sustained call over the last 15+ years for the increased implementation of updated practices in undergraduate STEM education. Though over the past few decades many researchers have developed and analyzed the efficacy of various evidence-based teaching practices (EBTPs) designed to improve the state of undergraduate STEM education throughout the country, the rate at which these EBTPs are implemented in undergraduate STEM classrooms remains low.

In order to better understand the specific factors that affect individual instructors' efforts to implement EBTPs, we …

In Their Words: Prospective Teachers' Experiences As A Context For Investigating Their Views Of Authority In A Mathematics Classroom, Brenda Lynn Rosencrans

Dissertations and Theses

Mathematics teacher educators enact inquiry-based preparatory courses with the underlying expectation that their students (prospective teachers) will take ownership (authority) of their mathematical learning through sharing their ideas and collaboratively discussing the reasonableness of their shared ideas. Yet, prospective teacher' expectations are often not yet in alignment with those of mathematics teacher educators, instead they enter these courses expecting their instructors to provide clear examples and directions for how to solve mathematics problems. This project investigates this dynamic through an authority lens, seeking to understand and characterize different views of authority prospective teachers hold and the impact these views have …

Identifying Advantages To Teaching Linear Regression In A Modeling And Simulation Introductory Statistics Curriculum, Kit Harris Clement

Dissertations and Theses

Statistical association is a key facet of statistical literacy: claims based on relationships between variables or ideas rooted in data are found everywhere in media and discourse. A key development in introductory statistics curricula is the use of simulation-based inference, which has shown positive outcomes for students, especially in regards to statistical literacy and conceptual understanding. In this dissertation project, I investigate students from the Change Agents for the Teaching and Learning of STatistics (CATALST) curriculum in activities I designed for learning statistical association and linear regression. First, I analyzed the informal line fitting strategies of CATALST students. Findings suggest …

Does Instructional Autonomy Matter? Exploring Job Satisfaction For Math And Non-Math Teachers In Low, Middle, And High Ses Schools, Hannah Sean Ellefritz

Dissertations and Theses

Throughout the 2000s, standards-based education policies decreased the autonomy of public schools across the U.S., deprofessionalizing educators and limiting their participation in the development of curriculum and instructional policy. Many education scholars argue that, rather than professionals with specialized skills and knowledge, standards-based reforms position teachers as technicians, accountable for measurable output in accordance with externally imposed standards. This literature suggests that such education policies may have implications for teachers’ job satisfaction, especially those working in schools or subject fields that are particularly susceptible to standardized curriculum and accountability procedures. Using nationally representative data from the Teaching and Learning International …

The Process Of Establishing A Blooming Chemistry Tool For Use In Undergraduate Chemistry Education And Research, Emryse Geye

Dissertations and Theses

While it is still common in college chemistry to assess student learning and skill with summative assessments, the CER community does not currently have a simple tool to determine and communicate whether an assessment is actually aligned with the outcomes of interest. In particular, as so-called evidence-based teaching practices and active learning strategies gain a foothold in college chemistry classrooms, the ability to communicate whether those (often labor-, cost-, and time-intensive) interventions are not only aligned with course outcomes, but also provide measurable benefit to students becomes more imperative. While college chemistry has made some strides in the area of …

Analyzing Classroom Discourse To Investigate Structuring Equitable Mathematical Talk In Small Groups And Whole-Class Discussions, Brittney Marie Ellis

Dissertations and Theses

Shifting classroom discourse to be more student-centered has become an integral part of reform-oriented instructional practices. At the same time, shifting discourse can open up opportunities for inequity to occur in the immediate learning environment as both the quantity and quality of mathematical talk changes. In this project, I examined complexities involved in such settings by using discourse analysis methods to explore the positioning of students relative to mathematics content and each other's mathematical ideas. First, I analyzed the ways teachers' discourse during group work enactments related to established equitable teaching practices. Findings from this study suggest communicating group tasks …

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 …

High School Students’ Nature Of Science Understandings And Scientific Argumentation Skills In The Context Of Socioscientific Issues, John Michael Williams

Dissertations and Theses

Today’s high school graduates are required to digest and interpret massive amounts of information related to science. National standards documents in science education promote the development of skills to effectively evaluate the credibility of scientific information, with the goal of producing citizens capable of making scientifically informed decisions after graduation. These skills include the ability to make reasoned arguments based on evidence (Scientific Argumentation [SA]) and an understanding of how scientific knowledge is generated, validated, and communicated (Nature of Science [NOS]). While the importance of these skills is not in dispute, the few studies that have examined the connection between …

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 …

Experiences Of Undergraduates And Graduate Teaching Assistants In Biology Course-Based Undergraduate Research Experiences, Emma Crystal Goodwin

Dissertations and Theses

Evidence of positive student outcomes from course-based undergraduate research experiences (CUREs) has sparked implementation of CUREs in introductory biology laboratory courses, as one approach to boosting student engagement in research. In a CURE, students collaborate with other students and instructors on a research project, where they conduct novel scientific research that has relevance to a local or scientific community. However, previous research rarely considers that graduate teaching assistants (GTAs) often teach introductory labs. The classroom role of GTAs expands in a CURE--they no longer need to simply teach a lab class, but also to serve as research mentors. GTAs, who …

Guided Reinvention As A Context For Investigating Students' Thinking About Mathematical Language And For Supporting Students In Gaining Fluency, Kristen Vroom

Dissertations and Theses

Fluency with mathematical language is important for students' engagement in many disciplinary practices such as defining, conjecturing, and proving; yet, there is growing evidence that mathematical language is challenging for undergraduate students. This dissertation study draws on two design experiments with pairs of students who were supported to encode their mathematical meanings with more formal language. I aimed to investigate the teaching and learning of mathematical language, and particularly the language in statements with multiple quantifiers, by engaging students in this type of activity. In the first paper, I investigated the complex ways in which the students in my study …

Short- And Long-Term Impacts Of A Deliberative Pedagogy In Introductory Biology And Chemistry Courses, Liz Rain-Griffith

Dissertations and Theses

There have been multiple national calls for curricular reform in college-level science, technology, engineering, and mathematics (STEM), including a need to instill democratic skills in students. Democratic skill building can be embedded in STEM classrooms through intentional "deliberative pedagogies" which include skills in: communication, collaboration, and application. We developed and implemented a deliberative pedagogy, Deliberative Democracy (DD), across introductory majors and non-majors biology courses and a majors chemistry course. In two separate studies, I took a longitudinal, qualitative research approach to understand introductory biology and chemistry students' experiences and perceptions of DD. For the first study, I tracked a cohort …

Mathematical Silences, Matthew Nathan Petersen

Dissertations and Theses

Previous studies have shown that mathematicians employ lengthy silences in their collaborations, contrary to the norms that govern every-day collaborations. Such results shows the relevance of an investigation of silence in mathematical collaboration. This dissertation builds off these results in a series of three papers. The first paper describes a methodology that can be employed in the investigation of silence in mathematical collaboration. The second paper analyses silence in the mathematical collaboration of students in junior-level introductory proof classes. It identifies two forms of mathematical activity, reading and ruminating, that students regularly engage in, and which violate the norms of …

From Theory To Practice: Interdisciplinary Science In Undergraduate Education, Brie Tripp

Dissertations and Theses

Science has undergone a major transformation in the 20th and 21st centuries with new fields emerging at the intersection of disciplines, such as bioethics, bioinformatics, and chemical ecology. Yet, opportunities to engage with interdisciplinary science, and the skills needed to work in these fields, are largely absent from undergraduate biology classrooms. As a consequence, students are potentially deprived of opportunities to think interdisciplinarily and engage with real-world issues that often necessitate interdisciplinary efforts. To be informed citizens in society and forward-thinking scientists in the workforce, undergraduate students will undoubtedly benefit from exposure to these interdisciplinary science experiences.

Given these considerations, …

Identifying A Starting Point For The Guided Reinvention Of The Classification Of Chemically Important Symmetry Groups, Anna Marie Bergman

Dissertations and Theses

The study of abstract algebra is both required for most mathematics majors and notoriously difficult. Much of the mathematics education literature on investigating student thinking in abstract algebra highlights student struggles with understanding even the most fundamental concepts. The abstract nature of the content of the course has been credited as one of the contributors to student difficulties. While there have been various instructional innovations designed to support students in better understanding abstract algebra, and group theory in particular, they have not specifically focused on the issue of the abstract nature of the content. My dissertation study aimed to develop …

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 …

The Impact Of Integrating Traditional Ecological Knowledge In Summer Camps On Middle School Students' Understanding Of The Nature Of Science, SapoóQ'Is WiíIt'es Ciarra Solina Greene

Dissertations and Theses

The Nature of Science (NOS) and traditional ecological knowledge (TEK) have commonalities in the knowledge bases: they are both ways of explaining the natural world; founded on a set of practices and the historical accumulation of knowledge; and part of the education is learning practices and developing knowledge of the concepts that are foundational to the disciplines. Throughout the United States, schools are attempting to strengthen students' understanding of NOS through various approaches, although few have adopted the integration of TEK into curriculum. This research assesses two summer camps for middle school students that are science focused, one with TEK …

Cooperating Teachers' Perceived Preparedness To Support Science Teacher Candidates For Culturally Sustaining Science Teaching, Keelan Purcell Lofaro

Dissertations and Theses

In the United States, many communities face challenges that require science, technology, engineering, and math (STEM) solutions. Those communities most affected by these challenges often lack opportunities in school to use their funds of knowledge as they develop STEM literacies that would equip them to address these challenges. With new national science standards and increasingly diverse student demographics in classrooms across the United States, teacher educators must utilize strategies that prepare science teacher candidates, who are predominantly White, with pedagogies that can support diverse learners in expanding their STEM literacies from their funds of knowledge. The problem of practice guiding …

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 Investigation Of The Impact Of High School Student Fine Arts Course Accumulation On Mathematics Course Achievement, Daniel Mackin Freeman

Dissertations and Theses

Science, technology, engineering, and mathematics (STEM) educational achievement is vital to economic competitiveness in the United States and abroad. Despite a concerted effort, the US lags well behind many similarly developed nations. Research suggests that the integration of fine arts education into traditional STEM curriculum (STEAM) boosts academic achievement in STEM subjects and closes gaps between low- and high-socioeconomic status students. Justifications for STEAM programs are based, however, on the unexamined assumption, for one, that fine arts courses instill creative and critical thinking skills that can be transferred to STEM subjects. The present study explores the impact of taking fine …

Computer-Based Instruction As A Form Of Differentiated Instruction In A Traditional, Teacher-Led, Low-Income, High School Biology Classroom, Cheryl Casey

Dissertations and Theses

In 2015 the U.S. continues to struggle with academic achievement in public schools. Average test scores from 15 year olds taking the Program for International Student Assessment placed the U.S. as 38th out of 71 countries (Drew Devlin, 2017). It is common to discuss elimination of the achievement gap as the single most effective way to improve the U.S.'s mediocre standing among the highest scoring countries in the world in primary and secondary student test scores (McGhee,2004; Flemming 2012). In the broadest sense of the term the "achievement gap" refers to the difference in academic success between different groups of …

Can A Three-Day Training Focusing On The Nature Of Science And Science Practices As They Relate To Mind In The Making Make A Difference In Preschool Teachers' Self-Efficacy Engaging In Science Education?, Colleen Meacham

Dissertations and Theses

As technology and our world understanding develop, we will need citizens who are able to ask and answer questions that have not been thought of yet. Currently, high school and college graduates entering the workforce demonstrate a gap in their ability to develop unique solutions and fill the current technology-driven jobs. To address this gap, science needs to be prioritized early in children's lives. The focus of this research was to analyze a science training program that would help pre-school teachers better understand Mind in the Making life skills, the nature of science, science practices, and improve their self-efficacy integrating …

Investigating Statistics Teachers' Knowledge Of Probability In The Context Of Hypothesis Testing, Jason Mark Asis Dolor

Analyzing The Online Environment: How Are More Effective Teachers Spending Their Time?, Scott Davis Barrentine

Dissertations and Theses

Teaching at an online school is so different from classroom teaching that traditional training includes few of the skills necessary to be a successful online teacher. New teachers to an online environment face a steep learning curve in how they'll use the instructional technology, prioritize their time, and establish relationships with their students. The literature has advice for these teachers about effective online practices, but there has been little research to establish which strategies are most effective in motivating students. This pre-experimental study, conducted at an online 6th-12th grade hybrid school, investigated the practices used more often by the most …

Using The Task Analysis Process With Teachers To Uncover Language Demands Within An Eight-Week Ngss Summer Course, Leah Plack

Dissertations and Theses

The state of Oregon has adopted the Next Generation Science Standards as well as the English Language Proficiency standards, both of which affect elementary school teachers. These standards adoptions challenge teachers and professional developers to rethink how they approach science conceptual understanding and language acquisition. The Math Science Partnership K-6 Instructional Specialist Grant made the decision to incorporate a Task Analysis process, which asks the participant to analyze the demands of a content-based task in the domains of content knowledge, analytical skills and language, into six eight-week summer courses focused on the Next Generation Science Standards. A pre and post-assessment …

Stereotype Threat And Effects Of Students' Perception Of Their Math Teacher's Fairness On Their Math Self-Efficacy, Alexis Jocelyn Devigal

Dissertations and Theses

Gender inequalities perpetuated by educational and occupational segregation may be exacerbated in part by socialization processes that occur in the years leading up to when high school students typically begin considering postsecondary options. Students’ feelings of self-efficacy in certain subjects can be an important factor that informs their decisions to pursue coursework and programs. This study used stereotype theory to understand how students' perceptions of their 9th grade math teacher's fairness affected their 11th grade math efficacy and how this relationship was moderated by the gender of the student and their math teacher. Using the High School Longitudinal Study of …

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 …
