The purpose of this study was to conduct a content validity analysis of the Teacher Impression Scale (TIS), which is an observer rating scale designed to assess preschool children peer social competence. The TIS was originally developed in the 1980s and used in research in the 1990s-2010s. The was the first step in an instrument development…

This mixed-methods study's main goal was to examine whether teachers' conflict intervention strategies are contingent upon children's insistence level (i.e., unwillingness or inability to understand others' perspectives) and whether this support leads to different outcomes. An additional goal was to under-stand teachers' perceptions of peer…

Almost five million children attend preschool in the United States each year. Recent attention has been paid to the ways in which preschool classrooms shape children's early language development. This article discusses the importance of peers and classroom composition through the lens of age and socioeconomic status and the implications for…

Adults adopt the traits of characters in narratives, but little is known about whether children do so. In Study 1, 7- and 10-year-olds (N = 96) heard a 2.5-minute recording about a professor or cheerleader. Reporting higher engagement in the professor narrative related to more time playing with an analytical toy (a Rubik's cube), whereas reporting…

Expanding on the extant body of research on content validity, this study applied the tenets of content validity research to the development of an expository book reading intervention focused on science for preschool students with language impairment. This example case explains how, guided by content validity research in healthcare interventions,…

Despite receiving little to no training in behavior management, paraprofessionals often support young students with or at risk of disruptive behavior disorders in elementary schools. The Behavior Support Coaching for Paraprofessionals (BSC-P) is a new evidence-based data-driven approach for enhancing paraprofessionals' skills in identifying…

Although basing instruction on learning trajectories (LTs) is often recommended, there is little direct evidence regarding the premise of an LT approach--that instruction should be presented (only) one LT level beyond a child's present level. We evaluated this hypothesis in the domain of early shape composition. One group of preschoolers, who were…

Models are central to the practice and teaching of science. Yet people often fail to grasp how scientific models explain their observations of the world. Realizing the explanatory power of a model may require aligning its relational structure to that of the observable phenomena. The present research tested whether "relational…

In this thesis, I present three related papers that collectively investigate the instructional supports on screen and in the media viewing context that influenced English and heritage language vocabulary knowledge in DLLs. In study 1, I examine how specific pedagogical approaches used in educational media might benefit DLLs. In study 2, I…
