Advocacy outcomes are not self-evident. Identifying advocacy outcomes is extremely difficult because they are often intangible, arising from (personal) interactions, and they are not always traceable. This challenges conventional evaluation methods, which is recognized in the advocacy evaluation literature. However, current evaluation methods…

This article shares lessons from the field with program evaluations in the English-Speaking Commonwealth Caribbean (ESCC) region. The research highlighted that the challenges faced by evaluators working in the ESCC are quite similar to those experienced by evaluators elsewhere. However, the findings note the impact of the region's colonial past…

Realist evaluation (RE) is a research design increasingly used in program evaluation, that aims to explore and understand the influence of context and underlying mechanisms on intervention or program outcomes. Several methodological challenges, however, are associated with this approach. This article summarizes RE key principles and examines some…

In test-centered standard-setting methods, borderline performance can be represented by many different profiles of strengths and weaknesses. As a result, asking panelists to estimate item or test performance for a hypothetical group study of borderline examinees, or a typical borderline examinee, may be an extremely difficult task and one that can…

Education policy makers must make decisions under uncertainty. Thus, how they think about risks has important implications for resource allocation, interventions, innovation, and the information that is provided to the public. In this policy brief we illustrate how the standard of evidence for making decisions can be quite inconsistently applied,…

The mathematics education community has routinely called for mathematics tasks to be connected to the real world. However, accomplishing this in ways that are relevant to students' lived experiences can be challenging. Meanwhile, mathematical modeling has gained traction as a way for students to learn mathematics through real-world connections. In…

In this study, we investigated two students', ages ten and eleven, emotions while they engaged in mathematical problem solving. During three task-based interviews, the students explored parts of the unsolved problem the Graceful Tree Conjecture. While they were engaged in the interviews, they self-identified the emotions of frustration and joy…

Your library is your classroom, and you are responsible for it no matter what's happening there. Ineffective classroom management can hamper or completely negate your efforts at creating a strong library program, and that's true whether you're a new school librarian just starting out or one with many years under your belt. This powerful resource…

Ten years ago, the author worked as the Director of Assessments for the District of Columbia Public Schools (DCPS). For temporal context, the author arrived after the first of the infamous test cheating scandals and left just before the incident that spawned a second. Indeed, the author filled a new position created to both manage test security…

A typical mathematics assignment consists of a block of problems devoted to the same topic, yet several classroom-based randomized controlled trials have found that students obtain higher test scores when most practice problems are mixed with different kinds of problems -- a format known as interleaved practice. Interleaving prevents students from…

In the first main section of this thesis, I investigate superirreducible polynomials over fields of positive characteristic and also over [set of rational numbers] and [set of integers]. An n-superirreducible polynomial f(x) is an irreducible polynomial that remains irreducible under substitutions f(g(x)) for g of degree at most n. I find…

Emotional and behavioral difficulties in children with autism often present problems for families seeking appropriate treatment interventions. Using data from the 2011 Survey of Pathways to Diagnosis and Services, ordinal logistic regression models were used to examine the association between parental perceptions about autism and their reports of…

In this report, we discuss background research on the development of student understanding of quadratic functions and present a provisional learning progression for quadratic functions and quadratic equations. We also describe task shells that are linked to the learning progression. The learning progression and task shells can be used as a…

This review (Prospero Registration Number: CRD42017057915) aimed to systematically identify and summarize existing research on the relationship between additional emotional and behavioral problems (EBP) in children with autism, and parenting stress (PS) and mental health problems (MHP) in their parents. Sixty-seven studies met criteria for…

Background: Among the most contested topics within special education research concerns racial disparities in students identified with disabilities. This phenomenon, referred to as disproportionality in special education placement, is historically rooted in concerns surrounding the overrepresentation of Black students in special education across…
