The History And Impact Of A College‐Level Field‐Based Course On Learner And Community Development, David M. Harwood, Leilani Arthurs
DBER Speaker Series
Providing students with inquiry‐based learning experiences was a key recommendation made in the National Academies' 2007 report, Rising Above the Gathering Storm: Energizing and Employing America for a Brighter Economic Future, and this presentation is about a model for providing such experiences to college‐level students through a field‐based geology course. GEOL 160 – Fundamentals of Geosciences in the Field was developed 10 years ago for undergraduate students preparing to be K‐12 science teachers. The goals of the course are to enhance undergraduate pre‐service science teachers’ (i) knowledge of geoscience and the nature of science, (ii) attitudes about science, and (iii) …

Young Children’S Understanding Of Conservation Concepts, Julia C. Torquati
Young Children’S Understanding Of Conservation Concepts, Julia C. Torquati
DBER Speaker Series
This presentation will summarize an investigation of young children’s conservation knowledge and reasoning. Eighty‐two preschool aged children (3‐5 years) were interviewed at two points in time six months apart using a semi‐structured interview. The interview protocol developed by Peter Kahn (2001) was used to assess children’s conservation attitudes. This was the first time the interview was used with preschool aged children. Children were asked questions about the importance of animals, plants, parks, and gardens, and whether it is acceptable to litter (and why or why not). Fifty‐seven of the children attended a preschool located at a nature center, ten children …

Prime Ideals In Two-Dimensional Noetherian Domains And Fiber Products And Connected Sums, Ela Celikbas
Prime Ideals In Two-Dimensional Noetherian Domains And Fiber Products And Connected Sums, Ela Celikbas
Department of Mathematics: Dissertations, Theses, and Student Research
This thesis concerns three topics in commutative algebra:
1) The projective line over the integers (Chapter 2),
2) Prime ideals in two-dimensional quotients of mixed power series-polynomial rings (Chapter 3),
3) Fiber products and connected sums of local rings (Chapter 4),
In the first chapter we introduce basic terminology used in this thesis for all three topics.
In the second chapter we consider the partially ordered set (poset) of prime ideals of the projective line Proj(Z[h,k]) over the integers Z, and we interpret this poset as Spec(Z[x]) U Spec(Z[1/x]) with an appropriate identification. …
Boundary Value Problems For Discrete Fractional Equations, Khulud Alyousef
Boundary Value Problems For Discrete Fractional Equations, Khulud Alyousef
Department of Mathematics: Dissertations, Theses, and Student Research
In this dissertation we are interested in proving the existence of solutions for various fractional boundary value problems. Our technique will be to apply certain fixed point theorems. Also comparison theorems for fractional boundary problems and a so-called Liapunov inequality will be given.
An Analysis Of Nonlocal Boundary Value Problems Of Fractional And Integer Order, Christopher Steven Goodrich
An Analysis Of Nonlocal Boundary Value Problems Of Fractional And Integer Order, Christopher Steven Goodrich
Department of Mathematics: Dissertations, Theses, and Student Research
In this work we provide an analysis of both fractional- and integer-order boundary value problems, certain of which contain explicit nonlocal terms. In the discrete fractional case we consider several different types of boundary value problems including the well-known right-focal problem. Attendant to our analysis of discrete fractional boundary value problems, we also provide an analysis of the continuity properties of solutions to discrete fractional initial value problems. Finally, we conclude by providing new techniques for analyzing integer-order nonlocal boundary value problems.

Commutative Rings Graded By Abelian Groups, Brian P. Johnson
Commutative Rings Graded By Abelian Groups, Brian P. Johnson
Department of Mathematics: Dissertations, Theses, and Student Research
Rings graded by Z and Zd play a central role in algebraic geometry and commutative algebra, and the purpose of this thesis is to consider rings graded by any abelian group. A commutative ring is graded by an abelian group if the ring has a direct sum decomposition by additive subgroups of the ring indexed over the group, with the additional condition that multiplication in the ring is compatible with the group operation. In this thesis, we develop a theory of graded rings by defining analogues of familiar properties---such as chain conditions, dimension, and Cohen-Macaulayness. We then study the …
The Weak Discrepancy And Linear Extension Diameter Of Grids And Other Posets, Katherine Victoria Johnson
The Weak Discrepancy And Linear Extension Diameter Of Grids And Other Posets, Katherine Victoria Johnson
Department of Mathematics: Dissertations, Theses, and Student Research
A linear extension of a partially ordered set is simply a total ordering of the poset that is consistent with the original ordering. The linear extension diameter is a measure of how different two linear extensions could be, that is, the number of pairs of elements that are ordered differently by the two extensions. In this dissertation, we calculate the linear extension diameter of grids. This also gives us a nice characterization of the linear extensions that are the farthest from each other, and allows us to conclude that grids are diametrally reversing.
A linear extension of a poset might …
Modeling And Mathematical Analysis Of Plant Models In Ecology, Eric A. Eager
Modeling And Mathematical Analysis Of Plant Models In Ecology, Eric A. Eager
Department of Mathematics: Dissertations, Theses, and Student Research
Population dynamics tries to explain in a simple mechanistic way the variations of the size and structure of biological populations. In this dissertation we use mathematical modeling and analysis to study the various aspects of the dynamics of plant populations and their seed banks.
In Chapter 2 we investigate the impact of structural model uncertainty by considering different nonlinear recruitment functions in an integral projection model for Cirsium canescens. We show that, while having identical equilibrium populations, these two models can elicit drastically different transient dynamics. We then derive a formula for the sensitivity of the equilibrium population to …

Learning To Teach Mathematics With Reasoning And Sense Making, Amy L. Nebesniak
Learning To Teach Mathematics With Reasoning And Sense Making, Amy L. Nebesniak
College of Education and Human Sciences: Dissertations, Theses, and Student Research
This study uses teacher research to examine teacher learning in the context of instructional coaching. The author, a mathematics instructional coach, engaged in an intense three-week coaching relationship with a high school Algebra teacher. A detailed description of the teaching and learning of quadratics that took place during this research provide information about what and how a teacher learns to teach mathematics with reasoning and sense making. Mapping the terrain of quadratics deepened the teacher’s understanding of the mathematical content and encouraged him to adapt his textbook in order to build mathematical reasoning. Through the coaching process, the teacher also …

This thesis provides a theoretical framework for combinatorial search, which is then applied to several problems in combinatorics. Some results in space-bounded computational complexity are also presented.
Obstacles To Addressing Race And Ethnicity In The Mathematics Education Literature, Amy Noelle Parks, Mardi Schmeichel
Obstacles To Addressing Race And Ethnicity In The Mathematics Education Literature, Amy Noelle Parks, Mardi Schmeichel
Department of Teaching, Learning, and Teacher Education: Faculty Publications
This Research Commentary builds on a 2-stage literature review to argue that there are 4 obstacles to making a sociopolitical turn in mathematics education that would allow researchers to talk about race and ethnicity in ways that take both identity and power seriously. The obstacles discussed are (a) the marginalization of discussions of race and ethnicity; (b) the reiteration of race and ethnicity as independent variables; (c) absence of race and ethnicity from mathematics education research; and (d) the minimizing of discussions of race and ethnicity, even within equity-oriented work.

Concept Inventory Design For Determining Students’ Conceptual Understanding Of Oceanography, Leilani Arthurs
Concept Inventory Design For Determining Students’ Conceptual Understanding Of Oceanography, Leilani Arthurs
DBER Speaker Series
Concept inventories are relatively new types of diagnostic instruments intended to measure student learning. Concept inventories exist for astronomy, biology, chemistry, engineering, fluid mechanics, geology, and physics. None is yet available for oceanography, and development of the Introductory Oceanography Concept Inventory Survey (IO‐CIS) serves to fill this gap. A context‐driven development strategy was designed to create this instrument. Qualitative methods utilizing grounded theory and classical test theory were used to construct it. Quantitative methods, including statistical methods associated with classical test theory and item response theory, were used to evaluate and further refine the IO‐CIS. The instrument is valid and …

Using Web-Based Key Character And Classification Instruction For Teaching Undergraduate Students Insect Identification, Douglas A. Golick, Tiffany M. Heng-Moss, Allen L. Steckelberg, David W. Brooks, Leon G. Higley, David Fowler
Department of Entomology: Faculty Publications
The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture specimen quizzes. The study also determined student performance on insect identification tasks was not as good as for family-level identification as compared to broader insect orders and arthropod classification identification tasks. Finally, students erred significantly more by misidentification than misspelling specimen names on prepared specimen quizzes. Results of this study support that short web-based insect identification …

Learning Interdisciplinary Pedagogies, Alison J. Friedow, Erin E. Blankenship, Jennifer L. Green, Walter Stroup
Department of Statistics: Faculty Publications
Advocates of interdisciplinary teaching and learning in higher education suggest that interdisciplinary courses “promise a wide range of desirable educational outcomes for students” (Newell 1994: 35). These outcomes include enhanced affective and cognitive abilities, increased understanding of multiple perspectives, greater appreciation for ambiguity, and superior capacities for creative thinking, among others (35). Despite claims about the possibilities interdisciplinary learning offers, we have few examples of how faculty from different disciplines work together to create interdisciplinary classroom environments where such outcomes can occur. In short, more examples of how faculty from different disciplines actually develop, engage, and revise interdisciplinary pedagogies with …

Improving Elementary American Indian Students’ Math Achievement With Inquiry-Based Mathematics And Games, Jamalee Stone, Edmund T. Hamann
Department of Teaching, Learning, and Teacher Education: Faculty Publications
Project Inquiry-Based Mathematics was a National Science Foundation Math-Science Partnership implemented in a Great Plains city school district with a significant K-12 Native American population. One goal of the project was to reduce the achievement gap between Native American and non-Native students enrolled in the district. This gap reduction was to be achieved using inquiry-based mathematics curricula along with cognitively guided instructional strategies, particularly at the elementary level. This study focuses on whether inquiry-based mathematics strategies were consistently implemented in three fifth-grade classrooms at K-5 elementary schools with significant Native American student populations. Test result of Native American students at …
