This dissertation focuses on strategies and techniques to enhance code comprehension skills among students enrolled in introductory computer science courses (CS1 and CS2). We propose a novel tutoring system, "DeepCodeTutor," designed to improve the code comprehension abilities of novices. DeepCodeTutor employs scaffolded self-explanation…

Research-based multi-text strategies (MTC) comprised of two-step verification, discrepancy-induced, cognitive-affective engagement, and reading as problem-solving models may assist students in furthering their reading comprehension in this Internet-based society. The purpose of this statewide quantitative study of principals in Title I elementary…

Reading comprehension is an extremely important skill that students need to be effective learners; however, a significant percentage of students are reading below grade level on a nationwide scale (National Assessment for Educational Progress, 2019; National Institute of Health as cited by Learning Disabilities Association of America, 2022). In…

The purpose of this study was to investigate and implement an effective model for reading professional development (PD) for elementary teachers. Cycle 1 data were collected from kindergarten through fifth grade elementary teachers to understand teachers' perspectives of effective PD. The findings suggested that if PD utilizes teacher collaboration…

Up until third grade, reading instruction is focused on learning to read, while in fourth grade and up, students begin reading to learn (Annie E. Casey Foundation, 2024; Grunke et al., 2013). This reading with purpose includes increasing critical thinking skills and using newfound reading skills to understand complex subjects such as math and…

This dissertation investigates the ways that natural languages evolve and what it means in the overall cultural evolution of society. Computational and modeling advances have made possible to explore large-scale text data and test hypothesis of language evolution. Similar to biological systems, natural languages are evolving systems with words as…

The purpose of this mixed-methods sequential explanatory study was to investigate the effects of watching text-relevant video segments on reading comprehension of a culturally unfamiliar text when technical words are present or absent. Therefore, 44 adult English Language Learners (ELLs) with higher-intermediate to advanced English language…

The growth of reading and cognitive skills is crucial for children's development. This study examined the utility of incorporating a cognitive framework for reading in intervention design among struggling readers receiving National Institute for Learning Development (NILD) Educational Therapy® over a 3- to 5-year period. Evidence from this…

Black boys in grades third through fifth are not developing reading comprehension skills compared to their peers in an urban southeastern school district. The purpose of this basic qualitative study was to explore perceptions of third through fifth grade reading teachers on reading comprehension of Black boys in this district. The conceptual…

Research on secondary student reading comprehension performance is scant, yet demands for improved literacy at college and career levels indicate that an understanding of trends and growth patterns is necessary to better inform teaching and learning for high school students. To improve understanding of reading performance at the secondary level,…

The heightened importance of foreign languages (L2) in the post 9-11 world demands more L2 listening research as listening is considered the most critical skill for most American military linguists. Some larger studies show that lexical knowledge can positively affect L2 listening (Chang, 2007; Mehrpour & Rahimi, 2010; Staehr, 2009), yet…

This quantitative, quasi-experimental research study was designed to determine the impact of a computer assisted reading instruction program on the fluency rates and comprehension skills of third and fourth grade students with reading disabilities at an Ohio suburban-metropolitan elementary school. Pretests established the participants' baseline…

The primary aim of this study was to examine the structure of processing speed (PS) in middle childhood by comparing five theoretically driven models of PS. The models consisted of two conceptual models (a unitary model, a complexity model) and three methodological models (a stimulus material model, an output modality model, and a timing modality…

With the online assessment becoming mainstream and the recording of response times becoming straightforward, the importance of response times as a measure of psychological constructs has been recognized and the literature of modeling times has been growing during the last few decades. Previous studies have tried to formulate models and theories to…

Many adolescents struggle to comprehend text, a fact which has led educational researchers to speculate that these reading struggles might be linked with students' levels of familiarity with the vocabulary and language found in these texts. However, few studies have identified the school-relevant language skills beyond vocabulary that contribute…
