Rett syndrome is a severe neurodevelopmental disorder that affects about 1 in 10,000 females. Clinical trials of disease modifying therapies are on the rise, but there are few psychometrically sound caregiver-reported outcome measures available to assess treatment benefit. We report on a new caregiver-reported outcome measure, the Rett Caregiver…

Social validity in the field of applied behaviour analysis is the measurement of the social significance of goals, the social appropriateness of procedures, and the social importance of the effects of a treatment. There is a paucity of rigorous research on social validity measurement as it relates to feeding treatment. To our knowledge, this is…

Many in the autistic community have expressed concerns regarding the use of behavioral interventions with autistic children, suggesting that these interventions may not be socially valid. Though behavioral interventions have evolved to be more naturalistic and child-centered, little structured research has been done to explicitly seek autistic…

Regression discontinuity (RD) designs have gained significant popularity as a quasi-experimental device for evaluating education programs and policies. In this paper, we present a comprehensive review of RD designs, focusing on the continuity-based framework, the most widely adopted RD framework. We first review the fundamental aspects of RD…

Single-case comparative studies could help identify efficient instructional procedures for individuals with disabilities. However, previous literature reported inconsistent efficiency results if multiple comparisons were conducted, indicating that within-participant replication was uncommon. In this review, we examined single-case comparative…

Many teacher education researchers have expressed concerns about the lack of rigorous impact evaluations of teacher preparation practices. I summarize these various concerns as they relate to issues of internal validity, measurement, and external validity. I then assess the prevalence of these issues by reviewing 166 impact evaluations of teacher…

Clearinghouses set standards of scientific quality to vet existing research to determine how "evidence-based" an intervention is. This paper examines 12 educational clearinghouses to describe their effectiveness criteria, to estimate how consistently[underlined] they rate the same program, and to probe why their judgments differ. All the…

Instructional leaders require timely and predictive data to guide post-pandemic systemic changes. We investigated the predictability of an observational instrument, the Rigor Appraisal, and its association with achievement and other school effectiveness measures in a sample of 53 schools in Illinois. We found that increases in the Rigor Appraisal…

Validation is needed for any newly developed model or framework because it requires several real-life applications. The investment made into e-learning in medical education is daunting, as is the expectation for a positive return on investment. The medical education domain requires data-wise implementation of e-learning as the debate continues…

Conversational skills, which are essential for effective social interactions and typically pose difficulties for individuals with autism spectrum disorder (ASD), include abilities such as initiating topics, engaging in back-and-forth dialog, and responding to conversational cues. Chatbots have been used in mental health fields, and the development…

In the United States, science education has experienced substantial shifts in the last decade. For in-service teachers, professional development programs (PDPs) play an important role in reform success. Despite well-known core features of effective PDPs, research still suggests a range of results among programs that claim to use those features. An…

Research practice partnerships (RPPs) are an increasingly popular approach for bringing together research and practice in ways that can improve and transform education. To date, however, evaluators have lacked measures to evaluate such partnerships. This paper describes a project to develop validity evidence for a survey to evaluate the…

In reviewing existing literature, scales that deal with peer relations' communicative effectiveness dimension within an educational context were not found. The purpose with this research was to develop a scale for communicative effectiveness of peer relationships for students. A total of 670 students from public/private high schools in Northern…

This study applied critical race theory (CRT) to provide a lens through which to critically analyze the preparation and described practices of White mentors in providing support to new teachers of color as they navigate racism in education contexts as novice educators. The purpose of this study was to explore induction mentors' perceptions of…

In this dissertation, I report results from a study that investigated the impact of students' engagement in a series of tasks in an introductory proof course that was designed to stimulate their learning of reading strategies to support their comprehension of mathematics proofs. Specifically, I investigated the impact of the design of five…
