Universal Design (UD) involves the creation of accessible, flexible products that are functional for a wide population of users. Our problem-based learning exercise challenges student teams to create products and services guided by the principles of UD. After teams generate their new product concept, a spokesperson from each team pitches it in…

In the years 2005 to 2019, the number of American women receiving a degree in engineering was below 20 percent. Furthermore, even after receiving a degree in engineering, 40% of those girls do not enter the profession. While the above graduation data is essential for understanding the problem at the end of the educational journey, it doesn't point…

Positive social relationships have been variously linked to mental well-being, and it is therefore important to more fully understand the factors that may impede positive relationship development. The aim of this study was to explore the relationships between elementary school-age children's emotion regulation, relationship problems, adaptive…

Many universities throughout the world apply student-centered approaches. Common to these is that projects, problems, challenges etc. stem from "real life". Mathematics is an effective tool to solve problems, but in this paper, we discuss how we reconcile the fact that mathematics is both a pure and an applied discipline with…

The present study investigated bidirectional associations between teachers' sense of inadequacy and self-efficacy and factors related to them across one academic year. Teachers (N = 52) rated their sense of inadequacy and self-efficacy in fall and spring, and reported the number of students in need of support in spring. The results of cross-lagged…

Proportional reasoning and knowledge of fractions are critical skills for completing algebra successfully, yet many students with mathematics learning disabilities (MLD) enter algebra classes without adequate prior knowledge of these skills. This study used a single-subject/case research, combined multiple-baseline and alternating-treatment design…

This dissertation was designed to foster a deeper understanding of population invariance in the context of composite-score equating and provide practitioners with guidelines for addressing score equity concerns at the composite score level. The purpose of this dissertation was threefold. The first was to compare different composite equating…

We will present a problem-solving method for the dynamics of a projectile that has two perpendicular acceleration vectors through rotation of the axes. This methodology of reparameterizing the two-dimensional system simplifies the speed optimization calculus.

Problem posing research in mathematics education has increased in the last decade. As a result, the intent of the present study is to examine and summarize the research that has been conducted. Specifically, we examined articles published from 2011-2020 that studied the impact of problem-posing instruction on students' problem-solving abilities.…

Academic and practice-based research constructs specific learning difficulties as a collection of lifelong, within-person conditions that negatively affect learning and daily functioning. Investigation has historically adopted a medical model, specifically a neurodeficit perspective. Conversely, neurodiversity has emerged as a concept that seeks…

Discrete mathematics brings interesting problems for teaching and learning proof, with accessible objects such as integers (arithmetic), graphs (modeling, order) or polyominoes (geometry). Many problems that are still open can be explained to a large public. The objects can be manipulated by simple dynamic operations (removing, adding, 'gluing',…

While helping proofread a book during my doctoral studies, I came across a chapter that included (among other things) a discussion of a set of problems and tasks involving the building of towers using only two (or three) colours of cubes (Maher & Ahluwali, 2014). Later that year, as I started my tenure track position at the University of…

The purpose of this study was to explore how teachers perceived challenging behavior in contrast to behaviors that exemplify social-emotional competence, while attending to how descriptions of behavior varied based on child demographics such as gender, race/ethnicity, and disability status. Using a DisCrit lens, this study was conducted under the…

Procedural arrangements of differential reinforcement of alternative behavior without extinction often involve presenting the same reinforcers for problem behavior and appropriate behavior, which is typically ineffective at reducing problem behavior and increasing an alternative response. However, manipulating reinforcement dimensions such that…

Background: A defining characteristic of expertise is the use of intuition to navigate tasks. The construct of intuition and its importance is well-studied in other disciplines, but little is known about how it translates to engineering. Existing literature on intuition does not clearly define the construct and its relationship to problem solving,…
