• ### From Frustration to Understanding: An Inquiry into Secondary Mathematics Teachers’ Experiences with Government Mandated Examinations

Spring 2014

The purpose of this study was to develop an understanding of secondary mathematics teachers’ experiences in a context of government-mandated examinations (GMEs). Having had my own experiences teaching mathematics courses where students wrote a GME, I had my own understandings of GMEs. From...

• ### Evaluation of Assistive Technology Resources for Access to Hands-On Activities by Students with Disabilities, and Assistive Technology Teams

2018-03-15

SSHRC PEG Awarded 2018: Two in-depth case studies will evaluate use of Lego Mindstorm robots and teaching materials developed specifically for these as math aids, by students with hand-based disabilities, their teachers, and Assistive Technology team. Quantitative data collected will include 1)...

• ### Dimensionality Reduction for fMRI Diagnostic Systems

Fall 2012

Functional Magnetic Resonance Imaging (fMRI) measures the dynamic activity of each voxel of a brain. This dissertation addresses the challenge of learning a diagnostic classifier that uses a subject’s fMRI data to distinguish subjects with neuropsychiatric disorders from healthy controls. fMRI...

• ### DEVELOPING MATHEMATICS FOR TEACHING THROUGH CONCEPT STUDY: A CASE OF PRE-SERVICE TEACHERS IN TANZANIA

Spring 2019

This descriptive qualitative case study investigates the question “In what ways does developing mathematics for teaching through concept study contribute to the professional knowledge and skills of pre-service teachers?” The concept studies were conducted in a classroom driven by five conditions:...

• ### Cohomological Invariants of Simple Linear Algebraic Groups Arising via the Killing Form

Spring 2019

Let $G$ be a linear algebraic group defined over a ground field $k$, and let $\mu$ be a $\Gal(k^\sep/k)$-module.A \tb{cohomological invariant} is a morphism $a:H^1(-,G)\to H^n(-,\mu)$ of two functors from the category of field extensions over $k$ to the category of setswhere $H^1(-,G)$ is the...

• ### Characterizing Population Heterogeneity of Salmonella Motion in Mucosal Environments Using Stochastic Modeling and the EM Algorithm

Fall 2022

Salmonella are pathogenic bacteria that infect many species including humans. This pathogen thrives in the gastrointestinal track of their hosts and propel themselves in mucus with motion structures called flagella. Each cell has multiple flagella that can rotate either synchronously, resulting...

• ### Canada Learning Loss Policy Report

2024-01-29

SSHRC CG awarded 2024: One notable negative outcome of pandemic educational disturbances is learning loss but the true extent of learning loss in Canada is currently unknown. This makes it challenging for Canada to to set evidence-based priorities, raise awareness, and implement effective...

• ### Being There for the Other: Towards a Phenomenology of Help in Mathematics

Fall 2013

A qualitative study, framed within a hermeneutic phenomenological stance, was undertaken to explore and describe the essence of the meaning of help in mathematics from the perspective of high school students. Participants were drawn from seven high schools located in the eastern and mid-eastern...

• ### Averaging for Fundamental Solutions of Parabolic Equations.

1997

Herein, an averaging theory for the solutions to Cauchy initial value problems of arbitrary order,ε-dependent parabolic partial differential equations is developed. Indeed, by directly developing bounds between the derivatives of the fundamental solution to such an equation and derivatives of the...

• ### Analysis of scaling limits of the Kinetic Chemotaxis Equations

Fall 2020

The kinetic chemotaxis equations have long been used to model biological processes. We will analyze a volume filling variant of the kinetic chemotaxis equations on the torus. Since the kinetic chemotaxis systems have well known blow-up solutions, we spend a considerable amount of time showing...
