Using a mixed-methods approach, the researcher investigated the generalization of Positive Behavior Supports Skills (PBIS) within an Early Childhood Special Education (ECSE) program, implemented with fidelity, as evidenced by statewide recognition for 10 years in a row, to the kindergarten setting in a Midwestern School District. Through…

Collection and analysis of students' writing samples on a large scale is a part of the research agenda of the emerging writing analytics community that promises to deliver an unprecedented insight into characteristics of student writing. Yet with a large scale often comes variability of contexts in which the samples were produced--different…

Educators aim to equip students with learning strategies they can apply when approaching new problems on their own. Teaching design-thinking strategies may support this goal. A first test would show that the strategies are good for learning and that students spontaneously transfer them beyond classroom instruction. To examine this, we introduce…

Successful text comprehension is a complex task, requiring a variety of cognitive skills and processes that support students in making inferences, integrating information across sentences in text, monitoring understanding, and gaining knowledge about text structure. For students with significant intellectual disability (SID), text comprehension is…

This applied dissertation study compared the effectiveness of the iPad-assisted and traditional flashcard-assisted instruction for teaching receptive labeling skills to learners with autism. A lack of access to certified service providers and insurance coverage and the inability to receive a diagnosis of autism prevent families from accessing…

Young children with disabilities are less likely to display age-appropriate social behaviors than same-age peers with typical social development, especially children who display social-communication delays. In this study, two concurrently operating single case designs were used to evaluate the use of progressive time delay (PTD) to teach children…

This study employs a meta-analysis of single-subject design research to investigate the efficacy of mobile device-based interventions for individuals with intellectual disabilities (ID) and to further examine possible variables that may moderate the intervention outcomes. A total of 23 studies, 78 participants, and 140 observed cases that met the…

This study adopted Ambridge's research paradigm to examine the effects of entrenchment, preemption, and verb semantics in second language (L2) acquisition of English "un-" prefixation. Three groups of Chinese learners of English (second- and fourth-year English majors and teachers of English) rated the acceptability of 48 "un-"…

Without a science background as sophisticated as that of a scientist, the evaluation of science in the media has proved to be a challenge to members of the public who are largely non-specialists. It is generally assumed that understandings of nature of science (NOS) will lead to this desired outcome of scientific literacy. This study examined the…

Internationally, efforts are being made for educational practice to be research-informed on the grounds that schoolteachers will implement what research shows will "work". However, teachers do not necessarily accept research findings; sometimes they contest them. This article considers teachers' contestation in two empirical studies,…

This dissertation examines the question of how phonological alternations are learnt. In constraint-based models of phonological learning, it is hypothesized that prior learning of phonotactics from the lexicon facilitates the learning of alternations. While this is an influential assumption, the empirical evidence for it is equivocal. In this…

The topic of this study was the way teachers of children with autism perceive the home-school collaboration and its impact on learning. This research addressed the gap in the literature on the topics of children with autism's performance gap in comparison to their age-equivalent peers. The research question was, "How do teachers of children…

Biased sampling occurs frequently in economics, epidemiology, and medical studies either by design or due to data collecting mechanism. Failing to take into account the sampling bias usually leads to incorrect inference. We propose a unified estimation procedure and a computationally fast resampling method to make statistical inference for…

Hampton (1988) discovered that people are subject to "overextension"--they categorize some things as falling under a conjunction (e.g., they categorize chess as a "sport which is also a game") but not as falling under both of the corresponding conjuncts (e.g., they do not categorize chess as a "sport"). Although…

Three experiments explored whether group membership affects the acquisition of richer information about social groups. Employing a minimal-groups paradigm, 6- to 8-year-olds were randomly assigned to 1 of 2 novel social groups. Experiment 1 demonstrated that immediately following random assignment to a novel group, children were more likely to…
