When We Grade Students’ Proofs, Do They Understand Our Feedback?, Robert C. Moore, Martha Byrne, Sarah Hanusch, Timothy Fukawa-Connelly

Faculty Publications

Instructors often write feedback on students’ proofs even if there is no expectation for the students to revise and resubmit the work. It is not known, however, what students do with that feedback or if they understand the professor’s intentions. To this end, we asked eight advanced mathematics undergraduates to respond to professor comments on four written proofs by interpreting and implementing the comments. We analyzed the student’s responses using the categories of corrective feedback for language acquisition, viewing the language of mathematical proof as a register of academic English.

Constructal Alkaline Membrane Fuel Cell (Amfc) Design, E. M. Sommer, J. V. C. Vargas, Lauber De Souza Martins, J. C. Ordonez

Faculty Publications

This paper introduces a structured procedure to optimize the internal structure (relative sizes, spacing) and external shape (aspect ratios) of a single alkaline membrane fuel cell so that net power is maximized. The optimization of flow geometry is conducted for the smallest (elemental) level of a fuel cell stack, i.e., the single alkaline membrane fuel cell, which is modeled as a unidirectional flow system. The polarization curve, total and net power, and efficiency are obtained as functions of temperature, pressure, electrolyte solution concentration (KOH), geometry and operating parameters. The optimization is subjected to fixed total volume. There are two levels …

Adjudicating Risk: Aids, Crime, And Culpability, Aziza Ahmed

Faculty Scholarship

The AIDS epidemic continues to pose significant public health challenges, especially given that the spread of the virus outpaces the AIDS response.¹ Importantly, HIV continues to disproportionately impact socially and economically marginalized communities. In countries with concentrated epidemics,² it is racial minorities, sex workers, men who have sex with men, and drug users who face the brunt of the epidemic.³ In the United States, the data is startling⁴ : 44% of new infections were among African-Americans, and among African-Americans contracting HIV, 57% were among gay and bisexual men.⁵ In 2016, the CDC found that one …

Evaluating The Effect Of The Digital Divide Between Teachers And Students On The Meaningful Use Of Information And Communication Technology In The Classroom, Andrew Thomas Grigg

Theses: Doctorates and Masters

In recent years the usage of Information and Communications Technology (ICT) in schools has become more prominent (Pegrum, Oakley, & Faulkner, 2013), with the majority of the focus being on hardware implementation (Hunter, 2013). However, teachers have generally struggled to integrate the use of ICT fully to promote learning in their classrooms (Sipilä, 2014). Therefore, schools may need to develop teachers’ ICT skills; this also being in response to students demonstrating higher levels of ICT skills within schools (Morgan, 2012). The well documented limitations in ICT skills of many teachers, and the likely increasing ICT skill levels of students’ is …

Gifted Students: Perceptions And Practices Of Regular Class Teachers, Tracy Taylor

Theses: Doctorates and Masters

The purpose of this research was to examine provision of differentiated learning experiences for gifted students in regular classes in Western Australian primary schools. Specifically, it was intended to explore differentiation strategies used with gifted students, issues faced by teachers in their efforts to provide for their gifted students, and teachers’ suggestions on solutions for these issues.

Presently reality in Western Australia is that gifted primary students spend at least 90% of their time at school in regular classes. Therefore, the regular class teacher’s role in implementing appropriate learning opportunities for these students is critical. Relevant literature clearly identifies the …

Can Changing The Timing Of Outdoor Air Intake Reduce Indoor Concentrations Of Traffic-Related Pollutants In Schools?, Morgan Macneill, Nina A. Dobbin, Mélissa St-Jean, Lance A. Wallace, Leonora Marro, T. Shin, Hongyu You, Ryan H. Kulka, Ryan W. Allen, Amanda J. Wheeler

Research outputs 2014 to 2021

Traffic emissions have been associated with a wide range of adverse health effects. Many schools are situated close to major roads, and as children spend much of their day in school, methods to reduce traffic-related air pollutant concentrations in the school environment are warranted. One promising method to reduce pollutant concentrations in schools is to alter the timing of the ventilation so that high ventilation time periods do not correspond to rush hour traffic. Health Canada, in collaboration with the Ottawa-Carleton District School Board, tested the effect of this action by collecting traffic-related air pollution data from four schools in …

The Stability Of Old Skills During Transfer, Craig P. Speelman, John D. Forbes, Kris Giesen, Matthew Parkinson, Lois Johnson

Research outputs 2014 to 2021

This research was designed to evaluate the extent to which power functions can predict performance on a task when performance context has been altered. Since power functions reliably describe performance improvements during practice, an assumption implicit in some theories of skill acquisition and transfer is that transfer performance will continue to improve as an extrapolation of the practice power function. In the training phase of Experiment 1, 120 participants practiced solving simple problems from the six-times table. In the transfer phase, these same problems were presented again, intermixed with problems from one of the six conditions differing in various respects …

Research outputs 2014 to 2021

Managing water is a grand challenge problem and has become one of humanity’s foremost priorities. Surface water resources are typically societally managed and relatively well understood; groundwater resources, however, are often hidden and more difficult to conceptualize. Replenishment rates of groundwater cannot match past and current rates of depletion in many parts of the world. In addition, declining quality of the remaining groundwater commonly cannot support all agricultural, industrial and urban demands and ecosystem functioning, especially in the developed world. In the developing world, it can fail to even meet essential human needs. The issue is: how do we manage …

Constellations – A Space In Time That’S Filled With Moving, Deanne Leber

Theses: Doctorates and Masters

Constellations in the sky have been a source of inspiration, in both science and literature, for aeons. Working within the constraints of the ‘official’ 88 constellations, as devised by the International Astronomical Union, this study involved researching the myths and histories of constellations, and then creating a collection of poems based upon those. Thematic connections between the eight modern constellation “families” or groups of constellations were explored and it is in these groupings that the poems work, to tie together, through experimentations with language, a somewhat cohesive fabric of poetry.

Each constellation consists of three poems. The first is a …

New Cost Model For Feasibility Analysis Of Utilising Special Purpose Machine Tools, Ana Vafadar, Majid Tolouei-Rad, Kevin Haywood

Research outputs 2014 to 2021

Special purpose machine tools (SPMs) have been widely used to perform drilling-related operations in high volume production including within automotive component industries. The first step in designing and manufacturing a SPM is a feasibility analysis. Since SPMs have relatively higher investment cost than other machine tools, this task must be performed before any investment on the preparation of detailed design. The present paper explores an economic feasibility analysis strategy which aims to make logical decision by assessing the strengths and limitations of an SPM in comparison with other machine tools. The mathematical product cost model for SPMs is proposed for …

Structural Geodesic-Tchebychev Transform: An Image Similarity Measure For Face Recognition, Ali Nadhim Razzaq, Zahir Hussain, Hind Rustum Mohammed

Research outputs 2014 to 2021

This work presents a new holistic measure for face recognition. Face recognition involves three steps: Face Detection, Feature Extraction and Matching. In the face detection process to identify the face area in face images, Viola-Jones algorithm has been used. Feature extraction is based on performing double-transformation, where discrete Tchebychev transform is performed on the geodesic distance transform of the grayscale image. Structural Similarity (SSIM) is applied to the resulting image double-transform to find matching factor with other image faces in the FEI (Brazilian) database. Performance is measured using a confidence criterion based on the similarity distance between the recognized person …

The Possibilities Of A Line: Marking The Glissando In Music, Cat Hope, Michael Terren

Research outputs 2014 to 2021

The glissando as it is deployed in Western art music notation carries with it a number of challenges to the hegemony of traditional harmony, rhythm, and notation. The glissando embodies the smooth line, unlike the striated pitch-time space of traditional Western music, which aligns the glissando to many philosophical concepts, as well as mathematical, scientific, and architectural disciplines. Select works by Iannis Xenakis, James Tenney and Giacinto Scelsi are discussed for their development of glissandi as integral formal components, especially around the glissando’s tendency to encourage stasis. Compositional attempts to combine the nature of glissandi with drone in the author’s …

Scm?, Stephen A. Lemay, Dave Mcmahon, Jeffery A. Periatt

AMTP Proceedings 2016

Supply chain management remains a young field, one that has struggled to define itself in the most literal sense. This research looks at some of the most available definitions of supply chain management, analyzes their content, and explains the essence of the definitional problem. It does not attempt to define supply chain management--that would be a bit like driving onto a crowded road while complaining about the traffic--but it does attempt to lay out the path or paths that need to be followed to arrive at a consensus definition.

Instructors' Perceptions Of Their Students' Conceptions: The Case In Undergraduate Mathematics, Wes Maciejewski

Faculty Research, Scholarly, and Creative Activity

How a student conceives the nature of a subject they study affects the approach they take to that study and ultimately their learning outcome. This conception is shaped by prior experience with the subject and has a lasting impact on the student's learning. For subsequent education to be effective, an instructor must link the current topic to the student's prior knowledge. Short of assessing their students, an instructor relies on their subjective experience, intuitions, and perceptions about this prior knowledge. These perceptions shape the educational experience. The current study explores, in the context of undergraduate mathematics, the alignment of instructors' …
