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…

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…

Teacher educators are charged with supporting adult learners as they prepare to collaborate with diverse families and colleagues. In this research, we examined how a cohort of teacher candidates (N = 29) developed over a semester in their understanding, dispositions, and knowledge of strategies for partnership through the "dilemmas"…

Whole number computations are a critical skill that serves as a foundation upon which higher-order concepts in mathematics are taught to children. To facilitate their instruction, educators often use multiple representations to support a child's cognition. Representations with physical manipulatives are widely studied through a graduated…

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…

There has been increasing emphasis in Barbados and the Caribbean region on providing quality education for children with diverse special education needs. The major system for identification of students with special education needs in Barbados relies on classroom teachers to initiate referrals of students to a centralized government office.…

Due to the lockdown measures and severe restrictions taken to reduce COVID-19 transmission, which has globally been inflicted on people since March 2020, a new type of education in the form of online homeschooling has brought the role of parents to the forefront. Using online semi-structured interviews, this study aimed to investigate parents'…

Offering secondary math educators an innovative holistic and process-orientated approach for implementing nonroutine problems into their curriculum, this book defines and establishes practical strategies to develop students' problem-solving skills. The text focuses on the process skills necessary to solve nonroutine problems in mathematics and…

Purpose: The purpose of the study is to determine how students perceive groupwork and identify patterns of less successful groups in online challenge-based learning. Design/methodology/approach: This study involved 29 university students working in nine teams in an online challenge-based course. The authors applied Volet's (2001) Student Appraisal…
