Extended school non-attendance, commonly named truancy or school refusal, has over the last decade attracted attention among educational researchers. This article points to a need for theoretical perspectives that can account for the complexity and ambiguity of the phenomenon. The article presents a critical analysis of the research field of…

Background: Power analyses for a cluster-randomized trial (CRT) require estimates of additional design parameters beyond those needed for an individually randomized trial. In a 2-level CRT, there are two sample sizes, the number of clusters and the number of individuals per cluster. The intraclass correlation (ICC), or the proportion of variance…

The goal of this paper is to present several methods of visualizing student activity and collaboration in problem-based learning (PBL) in ways that can augment understanding of the complexity within PBL classrooms as well as to provide insights into the use of specific visual representations to address research questions in PBL. Grounded in…

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…

Educational providers frequently respond to learning disruptions encountered by refugees, internally displaced persons, and migrant communities through online platforms. Learning modules in these digital spaces are often remotely designed, prescriptive and lack full appreciation of challenging circumstances faced by teachers and learners. To…

Background/purpose. It has been established that students with special educational needs should have equal opportunities for learning with the rest of the formal developmental students in a common school, regardless of their characteristics or difficulties. In an environment that promotes normal physical and emotional well-being, mental…

Background/purpose: This study investigated the effectiveness of Problem-Based Worksheets (PBWs) in improving conceptual understanding of logic gates. PBWs were designed with key characteristics that integrate authentic problem-solving, active student engagement, and conceptual scaffolding to support critical thinking processes. A total of 32…

The current study utilized a qualitative phenomenological design to explore Graduate Teaching Assistants (GTAs)' experiences related to being victimized in the workplace. Through individual interviews, rich information was collected related to types of workplace bullying behaviors GTAs experienced, factors that encourage and discourage reporting…

My journey in the field of stress and coping began in the mid 1980s when I was researching the rather new field of childhood depression. It was a relatively under-explored field, and as a clinical and educational psychologist it was becoming increasingly apparent that there were concerns of young people, with some of these reflected in their…
