Science learning is important for the well-being of individuals and society. Acquiring the knowledge necessary for success in science is not easy because science involves relational thinking, or the ability to abstract and generalize from similarities between concepts. Using relational words, or shared linguistic labels that identify commonalities…

This longitudinal case study investigated the developmental trajectories of two participants enrolled in an ITA oral communication course at Purdue University. The course provides language support to the ITA population who play a crucial role in higher education programs in the U.S. (Gorsuch, 2016). Over four months (i.e., one semester), I…

The purpose of the current dissertation is to map the relationships between first language (L1), writing quality, and syntactic complexity, accuracy, lexical complexity, and fluency (CALF) in second language (L2) writing. CALF are characteristics of language production that have been of significant interest in L2 writing research for the past few…

One in seventy-five college students sustains at least one mild traumatic brain injury (mTBI) each academic year. Individuals with TBI, including mTBI, tend to have difficulties with passage comprehension and reading rate, along with reporting reading to be effortful. As reading is fundamental to students' academic success, contributors to reading…

The purpose of the present study is to apply the item response theory (IRT) and testlet response theory (TRT) models to a reading comprehension test. This study applied the TRT models and the traditional IRT model to a seventh-grade reading comprehension test (n = 8,815) with eight testlets. These three models were compared to determine the best…

Research on morphological awareness has shown that it contributes to literacy outcomes. However, because of the way morphological awareness is traditionally measured, there is speculation that tasks may reflect cognitive flexibility, working memory, or some other type of executive processing, versus awareness of morphology. Further complicating…

Successful spoken language comprehension depends upon both sensory and cognitive processing. Since older adults often experience declines in one or both of these domains, and perform worse on some language processing tasks than younger listeners, an important question is how declines to both auditory perception and cognitive abilities affect…

This research was conducted to explore predictors and moderators of bullying involvement, social and emotional problems, vocabulary knowledge, and crimes. There was one main research question: (1) Is there a the relationship between adolescents with social and emotional problems as measured by the SDQ (Goodman, 1997) and adolescents'…

The purpose of this correlational study was to determine if variables known upon a group of students' enrollment in kindergarten had a significant relationship with their high-stakes reading assessment results obtained six years later, in the students' fifth grade year. Archival data was gathered from a rural northern Georgia school district.…

In order to be successful in an educational setting, a student must acquire a particular register of language specific to academia, or an academic register. It cannot be acquired through ordinary social intercourse. It is specific to school. Acquiring the academic register is the greatest challenge English Learners (EL) face during their academic…

In this study, a dynamic assessment was used to measure the morphological analysis skills of participating sixth graders. The primary aim of this research was to examine the utility of this dynamic assessment and specifically to identify whether this measure can differentiate among students based on reading proficiency. Twenty-seven…

This is a dissertation study focusing on the ability of deaf children to fast map common and newly learned novel fingerspelled words through a training task. It also explored the relationship between the ability to learn fingerspelled words and the children's reading and vocabulary skills. Learning was assessed using five domains: imitation,…

In an age of scientific method much of any individual's thinking is quantitative. He lives in a world in which every situation involves concepts of quantity, amount, size, or number. He employs number language, that is, number names and signs to express his quantitative ideas. These various number names and signs constitute the medium for his…
