The purpose of this study was to determine if the provision of topic choice in reading material could serve to increase reading fluency for struggling readers, and if it could do so to a similar degree as the provision of tangible extrinsic rewards. An alternating treatments design was used to compare three conditions: choice of passage topic,…

The purpose of this study was to investigate educator perceptions regarding the externalizing and internalizing behaviors of special education and general education students. The population for this study was three selected full inclusion elementary schools in Middle Tennessee. The research technique used in this quantitative study was causal…

Although social networks change over time, network dynamics remain an understudied area of social network research. The detailed logs that are a feature of online social networks allow for easier observation and capturing of social network evolution. This study examines the evolution of an online social network. The network is proposed to evolve…

Background: Many individuals with autism spectrum disorders (ASD) exhibit social cognitive impairments in the development of theory of mind (ToM), or the ability to attribute mental states to oneself and others. ToM has been shown to relate to reading comprehension for children and adolescents with typical development (TD) and with ASD. This study…

Recess is a vital piece of the elementary school day. The impact of this time extends beyond students' physical, emotional, and social health. Recess has also been shown to have a positive impact on the classroom performance of students. The purpose of this causal comparative study was to test the theory of the impact of recess in elementary…

This dissertation provides a comprehensive description of courtroom language as a register by exploring the situational and linguistic features of authentic and TV courtroom language, as well as four public sub-registers that occur within authentic and TV courtroom (opening statement, direct examinations, cross-examinations, closing argument). It…

This study was a comparative study that applied the quantitative methodology of an independent sample t-test. The purpose was to study the perceptions of K-12 regular and special education teachers related to socially assistive robots. The study consisted of teachers from elementary, middle and high schools in suburban areas of the mid-Atlantic…

In causal mediation analysis, the definitions of the natural direct and indirect effects involve potential outcomes that can never be observed, so-called a priori counterfactuals. This conceptual challenge translates into issues in identification, which requires strong and often unverifiable assumptions, including sequential ignorability.…

This study examined the effect of pre-reading vocabulary instruction on learners' attention and vocabulary learning. We randomly assigned participants (L1 = 92; L2 = 88) to one of four conditions: pre-reading instruction, where participants' received explicit instruction on six novel items and read a text with the items repeated eight times;…

We illustrate how early adolescents use different patterns of ability feedback to promote a positive self-concept of ability (SCA) in mathematics. Students can simultaneously use ability appraisals from parents and teachers, while also drawing information from peer, dimensional, and temporal comparisons. Although we find these five sources are…

Extant research has compared the processing of affectively laden words between L1 and L2. However, most studies used verbal stimuli that were validated for a single language or for both languages but using independent samples. We systematically compared ratings of valence, emotional intensity and subjective familiarity of negative, neutral,…

Atypical learning and memory in early life can promote atypical behaviors in later life. Less relational learning and inflexible retrieval in childhood may enhance restricted and repeated behaviors in patients with autism spectrum disorder. The purpose of this study was to elucidate the mechanisms of atypical memory in children with autism…

In the U.S., state adopted or developed college- and career-ready mathematics standards, including the Common Core State Standards for Mathematics, not only impact districts, students, and their teachers, but also university teacher preparation programs. In order to attain and sustain Common Core's vision of developing mathematically competent…

Within a language, there is considerable variation in the pronunciations of words owing to social factors like age, gender, nationality, and race. In the present study, we investigate whether toddlers link social and linguistic variation during word learning. In Experiment 1, 24- to 26-month-old toddlers were exposed to two talkers whose front…

This study compares the experts and the novices to investigate their information processing in dealing with the different degrees of recognition of shape-match stimulus by measuring the event-related potentials (ERPs). ERPs were recorded while 20 designers and 20 novices made shape-match judgments for table and chair sets. All of the tables were…
