Purpose: Gesture delay in autistic infants and toddlers has been widely reported. The developmental trajectory of gesture production during early childhood is understudied. Thus, little is known about the possible changes of gesture production over time. The present study aimed to document the development of gesture production in autistic children…

In a multiyear, multisite, randomized control trial, we examined the effects of comprehensive professional development designed to support teachers' data-based instruction (DBI) for students with intensive early writing needs. Teachers (N = 154; primarily special educators or intervention specialists) were assigned randomly to a treatment group (n…

To address the needs of a diverse group of students with reading difficulties, a majority of researchers over the last decade have designed and implemented multicomponent reading interventions (MCRIs) that provide instruction in multiple areas of reading yielding mixed results. The current study evaluates whether students' baseline word reading…

Early literacy is largely acquired through child-led learning, yet current ways to support and enhance it may present problems of coercion and adult control. The "Following in our Footsteps II" intervention sought to circumvent such problems by teaching parent and educator pairs of 46 preschoolers how to make everyday literacy and…

Poor comprehenders (PCs) are characterized by poor reading comprehension despite intact decoding and general cognitive ability. Poor word meaning knowledge is one of the earliest deficits associated with a PC profile. We examined processes underpinning word learning in PCs using a category learning paradigm. Adolescent participants (20 typically…

The purpose of this study was to investigate developmental gender differences in academic achievement areas, with the primary focus on writing, using the child and adolescent portion (ages 6-21 years) of the "Kaufman Test of Educational Achievement-Second Edition, Brief Form," norming sample (N = 1,574). Path analytic models with gender,…

In the current study, we employed a concurrent multiple probe across participants design to examine the effects of an intervention package (i.e., response prompting, frames, technology) on sentence writing for three participants, ages 10-12, with intellectual and developmental disabilities (IDD). Specifically, we taught participants to write…

The purpose of the study was to evaluate the effects of a system of least prompts procedure and use of a graphic organizer to teach the academic literacy standard of comparing characters in text for elementary students with moderate and severe intellectual disability. A multiple probe across participants design was used to evaluate the results.…

The conceptualization of giftedness continues to be a widely debated topic within the field. Recently, there has been a shift from a psychometric view of giftedness to inclusion of conative and contextual factors. How one defines and conceptualizes "gifted" drives assessment and identification practices. Conceptualization also guides the…

There is growing recognition of the need to end the debate regarding reading instruction in favor of an approach that provides a solid foundation in phonics and other underlying language skills to become expert readers. We advance this agenda by providing evidence of specific effects of instruction focused primarily on the written code or on…

The structural relations between the Cattell-Horn-Carroll abilities and reading achievement outcome variables across child and adolescent development were examined in the "Kaufman Assessment Battery for Children, Second Edition", and the "Kaufman Test of Educational Achievement, Second Edition", co-normed sample. We estimated…

The fundamentals of computer science are increasingly important to consider as critical educational and occupational competencies, as evidenced by the rapid growth of computing capabilities and the proliferation of the Internet in the 21st century, combined with reimagined national education standards. Despite this technological and social…

Researchers have previously shown that video prompting can promote vocational skill acquisition for students with autism, and in a prior study, we demonstrated a model to train a paraprofessional to implement this practice. In this study, we evaluated (a) the degree to which the paraprofessional generalized implementation to new students and…

Students who exhibit giftedness alongside a learning disability (GLD) often display asynchronous academic development, and a combination of strengths that mask areas of struggle. Early identification and intervention may offset students experiencing low self-confidence and motivation, ineffective self-efficacy, or a loss of love for learning…

This article reports on a 4-year follow-up study from the Learning Experiences and Alternative Program for Preschoolers and Their Parents (LEAP) randomized trial of early intervention for young children with autism. Overall, participants from LEAP classes were marginally superior to comparison class children on elementary school outcomes specific…
