Time As A Line: Helping Children Make Abstract Ideas Concrete, Rachel Mae Stenner
Time As A Line: Helping Children Make Abstract Ideas Concrete, Rachel Mae Stenner
WWU Honors College Senior Projects
This is a math education project that included research, a lesson plan, and actual in the classroom work with students. Under the advisement of Dr. Rebecca Borowski, I looked into how time, an abstract idea, is taught to young children who are just starting to learn what measurement is, and examined how teachers can better teach time as a more concrete topic. This focused on the idea of turning the abstract time concepts that are thrown at children into the more abstract ideas of both circular and then linear number lines, using physical materials to help guide the process.
Can Women Science?: A Climate Survey To Address Gender Inequity In Wwu’S Geology And Physics/Astronomy Departments, Raina Shaw
WWU Honors College Senior Projects
This research study aims to assess and analyze gendered differences in student perceptions of the environment and climate in WWU’s Geology and Physics & Astronomy Departments. Underlying hypotheses involve the perceptions, comfort, and discrimination of women and gender minorities in male-dominated spaces. We also theorize that these gendered differences will increase with seniority and more so within physics than in geology. In addition to testing these hypotheses, we sought to collect relevant student feedback on factors that influence their perceptions of the climate & environment, to identify areas for future study and formal program assessment. From 56 respondents, this study …
Cross-Disciplinary Learning Index: A Quantitative Measure Of Cross-Disciplinary Learning About Energy, Todd Haskell, Emily Borda, Andrew Boudreaux
Cross-Disciplinary Learning Index: A Quantitative Measure Of Cross-Disciplinary Learning About Energy, Todd Haskell, Emily Borda, Andrew Boudreaux
Physics & Astronomy
The structure of many science programs at the college level assumes that students are able to draw on and integrate ideas from multiple disciplinary contexts. However, most assessment tools focus on learning in the context of a single discipline. We describe the development and validation of an instrument to measure how well students are able to combine energy ideas from different disciplines into a coherent understanding of a phenomenon. The final version of the instrument consists of a pair of multiple-choice online assessments, along with a metric calculated from the assessment scores: the cross disciplinary learning index (CDLI). The items …
Making Upper-Level Math Accessible To A Younger Audience, Allyson Roller
Making Upper-Level Math Accessible To A Younger Audience, Allyson Roller
WWU Honors College Senior Projects
Symmetry is all around us. It appears on fabrics and on the buildings that surround us. Believe it or not, there is actually quite a bit of math that goes into generating these patterns, which are known as the seven frieze patterns. In my work, I explain how each unique pattern is generated using different types of symmetries. I also created a PDF of a children’s book about frieze patterns to ensure that people of all ages have the opportunity to learn about seemingly complex patterns.
Physics Inventory Of Quantitative Literacy: A Tool For Assessing Mathematical Reasoning In Introductory Physics, Suzanne W. Brahmia, Alexis Olsho, Trevor I. Smith, Andrew Boudreaux, Philip Eaton, Charlotte Zimmerman
Physics Inventory Of Quantitative Literacy: A Tool For Assessing Mathematical Reasoning In Introductory Physics, Suzanne W. Brahmia, Alexis Olsho, Trevor I. Smith, Andrew Boudreaux, Philip Eaton, Charlotte Zimmerman
Physics & Astronomy
One desired outcome of introductory physics instruction is that students will develop facility with reasoning quantitatively about physical phenomena. Little research has been done regarding how students develop the algebraic concepts and skills involved in reasoning productively about physics quantities, which is different from either understanding of physics concepts or problem-solving abilities. We introduce the Physics Inventory of Quantitative Literacy (PIQL) as a tool for measuring Quantitative Literacy, a foundation of mathematical reasoning, in the context of introductory physics. We present the development of the PIQL and evidence of its validity for use in calculus-based introductory physics courses. Unlike …
More Than Meets The Eye; Accessibility Of Scientific Information Through Art, Rachael Barrows
More Than Meets The Eye; Accessibility Of Scientific Information Through Art, Rachael Barrows
WWU Honors College Senior Projects
Science is inaccessible to learn in a myriad of ways. Financially it can be difficult to get information. It can also be hard to look up information on your own without knowing what to look for. Teaching science also involves a lot of reading that can be difficult for some disabilities. Through art, however, science can become more accessible, both to share and to learn. Visual learning benefits understanding and retention of information as well as creates clearer holistic concepts. Through paintings, this project shares some scientific information, exploring a way to share and teach science that is more accessible.

Designing Research-Based Instructional Materials That Leverage Dual-Process Theories Of Reasoning: Insights From Testing One Specific, Theory-Driven Intervention, Mila Kryjevskaia, Mackenzie R. Stetzer, Beth A. Lindsey, Alistair Mcinerny, Paula R. L. Heron, Andrew Boudreaux
Physics & Astronomy
[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] Research in physics education has contributed substantively to improvements in the learning and teaching of university physics by informing the development of research-based instructional materials for physics courses. Reports on the design of these materials have tended to focus on overall improvements in student performance, while the role of theory in informing the development, refinement, and assessment of the materials is often not clearly articulated. In this article, we illustrate how dual-process theories of reasoning and decision making have guided the ongoing development, testing, and analysis …

Toward A Framework For The Natures Of Proportional Reasoning In Introductory Physics, Andrew Boudreaux, Stephen E. Kanim, Alexis Olsho, Suzanne W. Brahmia, Charlotte Zimmerman, Trevor I. Smith
Physics & Astronomy
We present a set of modes of reasoning about ratio and proportion as a means of operationalizing expert practice in physics. These modes, or natures of proportional reasoning, stem from consideration of how physicists reason in context and are informed by prior work in physics and mathematics education. We frame the natures as the core of an emerging framework for proportional reasoning in introductory physics, that will categorize the uses of proportional reasoning in introductory physics contexts, and provide guidance for the development of reliable assessments. We share results from preliminary assessment items indicating that university physics students have difficulty …

Framework For The Natures Of Negativity In Introductory Physics, Suzanne W. Brahmia, Alexis Olsho, Trevor I. Smith, Andrew Boudreaux
Physics & Astronomy
Mathematical reasoning skills are a desired outcome of many introductory physics courses, particularly calculus-based physics courses. Novices can struggle to understand the many roles signed numbers play in physics contexts, and recent evidence shows that unresolved struggle can carry over to subsequent physics courses. Positive and negative quantities are ubiquitous in physics, and the sign carries important and varied meanings. The mathematics education research literature documents the cognitive challenge of conceptualizing negative numbers as mathematical objects—both for experts, historically, and for novices as they learn. We contribute to the small but growing body of research in physics contexts that examines …

Conformal Geometry Of Polygons, Michael Albert
Conformal Geometry Of Polygons, Michael Albert
WWU Honors College Senior Projects
Conformal maps are functions from subsets of the complex plane to the complex plane that locally preserve angles. Our goal is to understand conformal maps that pass to and from polygonal domains. In order to do so, we derive some of the basic theory of harmonic functions on simply connected domains. In particular, our goal with the first few sections is to prove the Schwarz Reflection principle. Using this, as well as other tools from complex analysis, we give an in-depth explanation of Tao’s proof of the Schwarz-Christoffel formula. This is a differential equation that allows one to compute a …

Quick Guide To Plant Families Of Western Washington, Maggie Hayward, John D. Tuxill, James M. Helfield
Quick Guide To Plant Families Of Western Washington, Maggie Hayward, John D. Tuxill, James M. Helfield
WWU Honors College Senior Projects
This guide is an expanded version of a booklet designed to help students identify native plants in western Washington. It has been expanded to include invasive and ruderal taxa commonly found in riparian areas. The purpose of this guide is to provide practical help for identifying plant families, and to facilitate a basic understanding of plant morphology. By observing morphological characteristics such as leaf arrangement and structure, the user can narrow an unidentified species down to the family level. Because this book does not go to the species level, it is meant to be used as a companion to other …
Do Men Matter? In Statistics, Probably, Michael Kelly
Do Men Matter? In Statistics, Probably, Michael Kelly
WWU Honors College Senior Projects
In statistical genetics, there are several parameters of a dataset which a researcher might, but which are difficult to estimate in practice. In this paper, we will be focusing on allele frequencies, null alleles, inbreeding coefficients and, to a certain extent, beta values. A common technique for obtaining these values, developed by Amy Anderson and her co-workers, is to jointly estimate all of them using an EM-algorithm and the method of maximum likelihood. Despite this technique being effective in general, it is currently unable to deal with males at X-linked markers. The purpose of this project is to modify the …
Preliminary Impacts Of Constructed Log Jams On Streambed Topography And Bed Temperature On The South Fork Nooksack River, Sam Kaiser
WWU Honors College Senior Projects
Salmon are an essential part of the culture, ecology and economy of the Pacific Northwest region of North America, but populations of some ecotypes are declining. One specific population, the Puget Sound chinook (Oncorhynchus tshawytscha), is listed as threatened under terms of the U.S. Endangered Species Act (ESA). The decline of this ecotype has implications not only for humans but also for all links of the ecosystem such as the populations of southern resident killer whales (Orcinus orca) which prey predominately on chinook salmon. Major threats to these fish include overharvest and habitat degradation due to …

Deblurring Images, Jamie Mcmullen
Deblurring Images, Jamie Mcmullen
WWU Honors College Senior Projects
Let the matrix B be a blurred version of a sharp image represented by the matrix X. Given B, we would like to recover X.
To accomplish this, we construct linear models of the blurring process that produced B from X. The idea is that we could then reverse the blurring to reproduce the original image.
For example, if the blurred image satisfies
B = CXRT
for some invertible matrices C and R, then we could recover X as
X = C-1B(RT)-1.
However, the blurring model …
The Energy Imbalance Market: Environmental Benefits Of Regional Market Integration In The West, Kristen E. Tarr
The Energy Imbalance Market: Environmental Benefits Of Regional Market Integration In The West, Kristen E. Tarr
WWU Honors College Senior Projects
Compared to other regions of the United States, the Western electric grid is fragmented and balkanized, due to lack of regional market coordination. As the West anticipates the growth of renewable energy, there is an evident need for regional market interconnection. The Energy Imbalance Market (EIM) is the first sub-hourly regional power-trading market in the West, allowing Western utilities to buy and sell electricity across the diverse geographic region (EIM, 2018a). By tapping into the flexibility and diversity of regional production profiles, the EIM reduces the variability and intermittency of renewable power. According to the 2017 quarterly benefits report, from …

Reduced Light Availability Diminishes Mycorrhizal Growth Response Of Invasive Forb, Regina O'Kelley
Reduced Light Availability Diminishes Mycorrhizal Growth Response Of Invasive Forb, Regina O'Kelley
WWU Honors College Senior Projects
Arbuscular mycorrhizal fungi (AMF) form mycorrhizae, a common, well-studied symbiotic relationship. Controls on the magnitude and direction of plant mycorrhizal growth response (MGR) remain obscured. Specifically, the influence of light availability in the MGR of an invasive forb, spotted knapweed Centaurea stoebe, has not been studied. Greenhouse studies exploring the growth response of knapweed to arbuscular mycorrhizae (AM) often fail to report light intensity levels, which could impact the quality of their data. I conducted a greenhouse experiment studying the MGR in spotted knapweed under shaded and unshaded conditions, designed to approximate light availability in ambient greenhouse and full-sun …

The Global Energy Crisis, Katie Calhoun
The Global Energy Crisis, Katie Calhoun
Facing the Future Lessons
The world is at an energy tipping point. Countries and communities can choose to be proactive or wait and be reactive, however it is much less costly to do the former. In this project, high school environmental science students will examine the current energy use and concerns in a named country or community, analyze the pros and cons of the current energy situation and how it effects the social, economic and environmental aspects of the culture, then create a more sustainable, resilient plan for that country.
Recognition, Internalization, Growth: Intuitive Design For Archival Representation, Jaime L. Ganzel
Recognition, Internalization, Growth: Intuitive Design For Archival Representation, Jaime L. Ganzel
Graduate Student Symposium
Although there is a pressing need for archival description and access systems to be more intuitive and user-friendly, the uniqueness of archival records presents significant barriers to establishing simplistic and standardized conventions for the representation of archival materials. Indecipherable finding aids and access tools prevent new and inexperienced researchers from accessing the unique information and documentation held in archives. This article aims to help open the archival record to new and non-traditional archival users, support individual development of archival literacy skills, and cultivate a greater level of archival awareness in our society by developing a usable model for archivists to …
