Coalescence: A Carnivore Coexistence Curriculum That Braids Indigenous & Western Ecological Knowledge Into A Relevant And Experiential Learning Opportunity For Youth, Stephanie Anne Barron

Graduate Student Theses, Dissertations, & Professional Papers

As grizzly bears (Ursus arctos horriblis) begin to reoccupy more of their historic range, and as humans and large carnivore populations continue to increase, incidences of human carnivore conflict are on the rise. A decolonial curriculum designed in collaboration with the Confederated Salish and Kootenai Tribe’s wildlife biologists stands to increase awareness of Indigenous ecological knowledge and teach youth about the importance of coexistence with carnivores. Additionally, this project could greatly influence youth perceptions of grizzly bears and other large carnivores. This research project examines the development and implementation of a carnivore coexistence curriculum for youth that is guided by …

Examining The Influence Of Secondary Math And Science Teacher Preparation Programs On Graduates' Instructional Quality And Persistence In Teaching, Danielle M. Rhemer, Will Rogers, Sherry Ann Southerland

Teaching & Learning Faculty Publications

This quantitative, non-experimental study explored the relationship between the features of math and science teachers’ preparation programs and their graduates’ instructional rigor and persistence in teaching. Five math and science teacher preparation programs from across the United States were examined. Six sets of instructional tasks were collected from forty-six recent graduates of these programs to provide insights into novices’ instructional rigor, and employment data were collected for thirty-seven of these graduates three to eight years after graduation. Regardless of the program’s features, all teachers could design and implement instruction with moderate to high rigor. However, this ability was not the …

Prospective Teachers' Conceptions Of Area, Betsy Mcneal, Sayonita Ghosh Hajra, Michael Battista, Ayse Ozturk

Teaching & Learning Faculty Publications

This study explored 10 prospective teachers’ (PTs’) understanding of the area of a rectangular region using square and non-square rectangular area-units. In an hour-long interview, each PT was first asked to explain how they would find the area of a given rectangular region in terms of a non-square notecard. For several PTs, this task prompted discussion of a square unit defined by the edge of the notecard. In a second task, PTs were presented with a rectangular array of squares and were asked to explain to a fictional child why multiplying length times width does not count the top left …

Payday Power-Up: Let's Make A Raise Distribution, Ayse Ozturk

Teaching & Learning Faculty Publications

This study illustrates a problem-solving activity reflective of a real-life situation wherein high school students articulate their reasoning while contemplating the effectiveness and fairness of distributing raises. Study data were gathered via teaching experiment methodology in problem-solving sessions at a mathematics camp for secondary students. Examination of the data indicated that students sought entry points for problem-solving by making assumptions and pinpointing crucial variables. Framing mathematics within the concept of fairness encouraged students to review their work, engage in active listening, and find purpose in mathematical reasoning.

The aim was to explore the perceptions of these students regarding their enrolment in higher-level mathematics courses. Data from 1633 students were collected using a survey instrument comprised of 12, 5-point, Likert-scale items. Data were analysed by applying two statistical procedures: calculating frequencies of the 12 items …

Mathematical Connections In Preservice Secondary Mathematics Teachers’ Solution Strategies To Algebra Problems, Vesife Hatisaru, Kaye Stacey, Jon R. Star

Research outputs 2022 to 2026

This study investigated the mathematical connections found in the solutions provided by 22 preservice secondary mathematics teachers to a set of algebra problems. Interest in, and research on, mathematical connections has gained prominence of the past decade. Here, we use the Extended Theory of Mathematical Connections or ETMC to explore the types of connections that this framework does and does not capture in the preservice teachers’ solutions. The ETMC surfaced four types of mathematical connections across four problems: ‘different representations’, ‘procedural’, ‘part-whole’ and ‘meaning’. The other types of connections defined in ETMC such as ‘reversibility’ or ‘feature’ were not found …

Teacher Expectations Of Student Strategies For Algebra Problems, Vesife Hatisaru, Olivia Johnston, Julia Collins, Wendy Harmon

Research outputs 2022 to 2026

This paper investigates the expectations that a group of preservice secondary mathematics teachers had for how students would approach four particular algebra problems. Their responses to a set of open-ended items were content analysed. Findings show that the teachers ranged in the expectations that they held for their students. Some teachers expected their students would approach the problems with more sophisticated problem-solving strategies, but many of the teachers expected that the students would only use less desirable “guess-and-check” strategies. We believe teachers’ expectations for student strategies for problem-solving is a topic that warrants further investigation.

Secondary Mathematics Teachers’ Mathematical Competence, Vesife Hatisaru, Julia Collins, Steven Richardson, Constantine Lozanovski

Research outputs 2022 to 2026

Whilst educational goals in recent years for mathematics education are foregrounded the development of mathematical competencies, little is known about mathematics teachers’ competencies. In this study, a group of practising teachers were asked to solve an algebra problem, and their solutions were analysed to determine the competencies apparent (or, equally importantly, absent) in these solutions. The most demonstrated competencies were devising strategies and mathematising, whilst communication and reasoning were mostly missed. The research provides a detailed methodology on how mathematical competencies can be assessed in the context of problem solving.

Theorizing Mathematical Proof As Becoming: A Deleuzio-Guattarian Investigation, Joshua P. Case

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this dissertation, I utilize the post-structural philosophy of Gilles Deleuze and Félix Guattari as a lens for investigating the proof process. Deleuze and Guattari were both post- structural philosophers who, like many in this tradition, troubled traditional notions related to stable identities, meaning, language, and mathematics. For Deleuze, sense and meaning is not the result of a sterile, transcendent effect or condition that is associated with propositions and states of affairs. Rather, it is the result of a material production that emerges from the world and that has independence from language and the mind. I apply this framework to …

Incorporating Evidence-Based Teaching Practices In A Civil/Environmental Engineering Course To Improve Learning, Julie Anne Wildschut

University Faculty Publications and Creative Works

The most important goal of teaching is student learning, passing on information from the instructor to the student so they can apply those concepts and skills months and years after instruction. However, this goal is not easily accomplished. Thinking and learning take significant effort and students often resist putting in the required work. Additionally, the increasingly diverse student population and recent disruptions to traditional classroom learning require instructional design to meet learning outcomes. Three evidence-based teaching practices including retrieval practice, spaced (distributed) practice, and interleaving were incorporated into a hydraulics course to improve student learning and evaluated for their effectiveness. …

An Exploration Of Misconceptions In Introductory Physics, Christopher Mattthew Wheatley

Graduate Theses, Dissertations, and Problem Reports (ETD)

The study of student misconceptions about physics concepts has long been an important area of inquiry in physics education research (PER). The research discussed in this dissertation builds upon the developments in PER by exploring the prevalence of consistently held undergraduate student misconceptions in introductory calculus-based physics. This thesis explores the nature of student misconceptions, mistakes, and naive answering patterns in both introductory undergraduate Newtonian mechanics and electromagnetism by applying a network analytic technique called module analysis to student responses to different concept inventories from institutions of various levels of incoming physics preparation. Each study applying these methods also demonstrates …

A Qualitative Analysis Of Secondary Mathematics Teachers’ Development Toward Teaching Mathematics For Social Justice, Catherine Lynne Manley

Graduate Theses, Dissertations, and Problem Reports (ETD)

While some might say that mathematics is neutral, free from political and social bias, social justice concerns can be found in the day-to-day actions of teachers in mathematics classrooms. Teaching mathematics for social justice requires teachers to gain knowledge of the world and systems of oppression as well as current efforts to both address systemic issues as well as the fight for those in power to maintain their cultural capital. Mathematics teachers also need to learn the pedagogical practices that support social justice in education and the specific ways in which mathematics content can be used as a tool to …
