The purpose of this dissertation was to use the technology of text mining and topic modeling to explore unobserved themes of medical case reports that involve medical imaging. Case reports have a valuable place in medical research because they provide educational benefits, offer evidence, and encourage discussions. Their form has evolved throughout the years, but they have remained a key staple in providing important information to the medical communities around the world with educational context and illuminating visuals. Examining medical case reports that have been published throughout the years on multiple medical subjects can be challenging, therefore text mining and topic modeling methods were used to analyze a large set of abstracts from medical case reports involving radiology. The total number of abstracts used for the data analysis was 68,845 that were published between the years 1975 to 2022. The findings indicate that text mining and topic modeling can offer a unique and reproducible approach to examine a large quantity of abstracts for theme analysis.

This dissertation explored the cost and value of 1:1 computing programs in high schools in Texas. The study examines whether the total cost of ownership of these programs can be justified by the student testing gains and graduation rates. It investigates whether student learning outcomes show a definable correlation between positive gains and the implementation of 1:1 computing programs. The study also explores whether there is a measurable return on investment of 1:1 programs based on testing gains and graduation rates. The research used the State of Texas Assessment of Academic Readiness exam scores to validate assumptions and test the hypothesis. The study found no clear link between the addition of 1:1 computing programs and the realms of student success. While there is marginal improvement in student outcomes, there is only circumstantial evidence that laptops and devices are the catalysts for the change. The dissertation also found that the total cost of ownership (TCO) is a significant portion of the district's spending, costing millions of dollars, and that the financial disclosure and budget information data was either missing, incomplete, or over-generalized, causing an issue for assessing program effectiveness or ROI. Despite this lack of transparency, there is a slight positive …

The purpose of this three-article dissertation was to expand knowledge and theory regarding digital tool use in biology laboratory courses, such as microbiology, which requires specific laboratory skill development through the perception of instructors and students. Article 1 establishes the broad digital literacy and fluency problem in education by providing definitions and the context behind digital literacy fluency and its impact on acquisition of knowledge in digital learning environments. The study provided a picture of the lack of knowledge about the use of digital tools in education and practical problems around appropriate implementation, infrastructure, and preparedness. Article 2 presents results of a literature research study about the foundational, pandemic-induced, and current digital tool use in biology and microbiology lab courses. Recommendations for improvement in digital tool implementation, pedagogical approach, and appropriate selection to meet learning outcomes were provided.

The study identified challenges and benefits of digital tool use in virtual microbiology lab courses, unique challenges of underrepresented populations, and the need to develop an instrument to capture the context of this …

This dissertation aimed to research the possibility of integrating a supplemental video system in a surgical residency for educational use. A needs analysis was to be conducted in order to find if current stakeholders would accept such a system within a surgical residency: (a) surgical residents, (b) teaching physicians, and (c) administrators. The study aimed to research factors that complicate the current educational setting for surgical residents, such as time allotted for learning, fatigue during learning opportunities, teaching physicians time and effort into teaching responsibilities, and the cost of such systems and their perceived value to administrators. Also investigated was the type of learning theories best suited to creating a supplemental video system in a hospital setting. After this, a set of interviews was conducted amongst the stakeholders to evaluate the needs of the residency and the willingness of all parties to accept the system into their educational structure. What was found was a high level of interest in a more centralized learning management system, which is the central depository for all educational materials to be used by the residents. Most agreed that the learning environment lacked structure and optimally required something more substantial than adding supplemental videos to the …

The dissertation aims to expand access through a low-cost technological innovation system S-MLS to learners in underdeveloped areas with difficulties in accessing education. Technology is advancing rapidly. However, many parts of the world need access to educational advances, which are hindered due to war, political situations, and low literacy and income. A qualitative phenomenological approach explores the lived experience using the solar-powered computing and learning management system (LMS) to support the development of educational access in underrepresented societies, developing countries, and rural areas where access to proper classroom education is non-existent. Proof of concept is used with a group of students in a rural area, a developing country, and within an underrepresented population to check the feasibility of using the equipment in a real-world setting. A technology acceptance model would be used to identify the user's perceived interest and user acceptance. The community of inquiry theory would find the first-hand experience and point of view of the learner. The student group interviews would be through semi-structured interviews. Observations, surveys, video/audio recordings, and artifacts would be gathered for further analysis. The data collected would be analyzed using interpretative phenomenology analysis (IPA), close examination, and management of development themes through thoughts, observations, …

This research study examined the implementation of an extended reality (XR) lab on a community college campus to facilitate student and faculty access to immersive learning resources. The study, conducted during one skills day, involved 46 students and was designed to understand if integrating immersive VR into emergency medical technician (EMT) education could enhance learner confidence and motivation, develop problem-solving and analytical thinking skills, and thus connecting the classroom learning with real-world application. The majority of participants reported increased motivation and engagement, alongside improvements in learning outcomes like knowledge retention and skill development. Applying the unified theory of acceptance and use of technology (UTAUT) model revealed performance expectancy, effort expectancy, social influence, and facilitating conditions as key determinants of VR adoption in EMT education. While no significant overall performance enhancement was observed, VR training showed potential to boost motivation, confidence, and specific performance aspects. Furthermore, student perceptions towards VR in EMT education were largely positive, thereby suggesting its utility in immersive scenario training, skill acquisition in a risk-free environment, enhancing learner engagement, and real-world situational preparedness. VR demonstrated promise as a transformative tool in EMT education, necessitating further research to fully exploit its potential in diverse learning environments.

The purpose of this dissertation was to understand and compare the effect of training non-native English Speaking (NNES) learners (N = 480) in two distinct learning environments, (i) traditional face-to-face and (ii) online synchronous hybrid learning (SHL). In the traditional training mode, NNES learners (n = 360) were trained by NNES voice and accent (VANC) trainers in a physical, face-to-face setting. In the second, CAPT+SHL training mode, the NNES learners were trained by NNES VANC trainers with the help of a native-English computer-assisted pronunciation training (CAPT) tool in an online SHL environment. Factor analysis, higher-order factor analysis, hierarchical cluster analysis, and multidimensional scaling yielded a reliable scale, Eddie's Voice Test (EVT). Multiple regression yielded a predictive model between NNES pronunciation and their performance. In addition, the CAPT+SHL training mode produced higher scores on pronunciation and performance than the traditional training mode, suggesting a combination of NES and NNES VANC instructors are more effective in training NNES learners than NNES instructors by themselves. The case study (n = 3) on VANC trainers' perception of CAPT and SHL yielded three themes: (1) challenges with synchronous hybrid learning (sub-themes include physical challenges, social challenges, and cognitive challenges); (2) computer-assisted pronunciation training (CAPT) impact …

Demand for the skill of critical thinking is extensive in both higher education and in the workforce. The purpose of the current research is to examine the relationship between critical thinking educational efforts (e.g., programs incorporating high impact practices) and higher education student outcomes. For this study, student outcomes were defined as cumulative grade point average and student program retention. The study used existing data which were obtained from a large public research university in the southwest United States. The study found that higher critical thinking was significantly associated with higher overall GPA, and this relationship was stronger in males as compared to females. However, students' critical thinking was not significantly related to program retention. Findings from this study appear to confirm previous studies indicating a positive relationship between students' ability to think critically and GPA. The study also suggests that elements promoting critical thinking can be successfully embedded into undergraduate curricula through various means, including the use of high impact practices.

Manually grading essays and providing comprehensive feedback pose significant challenges for writing instructors, requiring subjective assessments of various writing elements. Automated essay scoring (AES) systems have emerged as a potential solution, offering improved grading consistency and time efficiency, along with insightful analytics. However, the use of AES in English as a Second Language (ESL) remains rare. This dissertation aims to explore the implementation of AES in ESL education to enhance teaching and learning. The dissertation presents a study involving ESL teachers who learned to use a specific AES system called LightSide, a free and open text mining tool, to enhance writing instruction. The study involved observations, interviews, and a workshop where teachers learned to build their own AES using LightSide. The study aimed to address questions related to teacher interest in using AES, challenges faced by teachers, and the influence of the workshop on teachers' perceptions of AES. By exploring the use of AES in ESL education, this research provides valuable insights to inform the integration of technology and enhance the teaching and learning of writing skills for English language learners.

The study explores the effectiveness of multimodality teaching using the 4MAT Model. A meta-analysis was conducted with empirical studies on instruction via multimodality teaching in preschool, K-12, and higher education. The studies in the meta-analysis involved an experimental and control group. The control group received traditional teaching lessons, and the experimental group received multimodality teaching. A text analysis was conducted to examine the trends in the advantages of the 4MAT model versus traditional methods. The literature review analyzed the cognitive theory of multimedia learning, advances in multimedia teaching effectiveness assessment, transforming traditional teaching through the 4MAT model, 4MAT model and learning, the importance of multimodality teaching, the origin of multimodality teaching, the 4MAT model, and multimodality teaching and student achievement. This research aimed to determine a better understanding and increase learning achievement by using the 4MAT model versus traditional teaching methods.

The purpose of this study is to analyze which behaviors are or are not helpful for debugging when a novice is in a state of unproductive persistence. Further, this project will exploratorily use a variety of analytical techniques -- including association rule mining, process mining, frequent sequence mining, and machine learning-- in order to determine which approaches are useful for data analysis. For the study, programming process data from hundreds of novice programmers were analyzed to determine which behaviors were more or less likely to be correlated with escaping a state of unproductive persistence. Of these events, only three had a statistically significant difference in their rates of occurrence and large effect sizes: file, edit, and compile events. While the data set cannot reveal a user's motivation for a file event, the most logical explanation of these events is that the user is tracing the code. Thus, a higher rate of file events suggests that code tracing (with the goal of code comprehension) is a key behavior correlated with a student's ability to escape a state of unproductive persistence. On the other hand, editing events are far more common in unproductive states that are not escaped. A content analysis suggests …

Existing data collected by the Texas Education Agency's Exit Survey by preservice teachers completing an educator preparation program was used to conduct a quantitative study. Data was imported into SPSS to conduct statistical analysis. The findings are discussed and recommendations for future research are provided to inform future development of technology integration in educator preparation programs.

The need for online remote working from home significantly increased due to the COVID-19 pandemic. This unexpected crisis forced individuals and organizations to rapidly transition from face-to-face training to remote learning at home. This switch happened overnight and was not optional but necessary. Employees had to adapt to new online learning techniques, seeking to preserve the same level of learning as working from the office. The study participants were male and female remote workers in the United States aged 18 and over. A questionnaire focused on evaluating online training in the workplace and a survey measuring two types of attitudes related to the transfer of training and technology integration while taking online training courses that were distributed online. The study collected a total of 50 responses from participants for analysis. According to the study results, employees noted some positive features of remote learning, such as flexibility, self-paced learning opportunities, and faster content absorption. Areas employees identified for improvement were closely related to the causes of complaints, such as network and technology issues, using a learning management system (LMS), instructions for using an LMS or course management system (CMS), face-to-face tech support, distractions, and suitable workspace at home. The study's results …

Furthermore, the results demonstrated that the professional nursing education of the study participants was devoid of interruption and interruption management education in the classroom, lab, and high-fidelity simulation. The themes that emerged from this study describe the current state of the second semester nursing student's …

The purpose of this qualitative case study was to define and describe the work of external instructional design consultants. Study participants included seven instructional designers with varied educational backgrounds and work experience who work in a variety of contexts supporting clients in the design and delivery of learning experiences. All seven participants completed an initial survey with demographic and background questions. Five participants then took part in semi-structured interviews. Collected data was coded using both deductive and inductive methods with each case considered individually before combining the data for analysis across cases. Study findings support previous research suggesting that the work of instructional designers is dependent on context. Results further indicated that external instructional design consultants regularly engage in project management, communication and collaboration, and the analysis and evaluation components of the instructional design process, all in keeping with existing literature. External instructional designers differed in that they do more sales-related work, and, in the analysis process, focus more on client needs than learner characteristics. Study participants were invested in creating high quality, engaging learning experiences, while also willing to accommodate the unique challenges facing any given client. The study findings suggested that prospective employees' instructional design knowledge is of …

This study examined the challenges companies encounter attempting to fill job vacancies with applicants having the requisite skills. Of the 115 journals evaluated as part of the literature review, 64% of the documents identified issues related to workplace skills development deficiencies in industry and academia. Additional findings related to vocational training programs, training for youth, training content issues, and investments in skills training are evaluated. The literature review suggests both industry and academia struggle with developing and training students and the workforce with the new technology skills demanded in today's workplace. A research study, conducted in an industrial manufacturing company, was performed based on two data sets (defect quantities and repair hours). Each of the data sets consisted of production performance data collected during three time periods (pre-treatment, proximal treatment, and distal post-treatment). The Treatment consisted of the development of a training course focused on the assembly and installation of electrical harness assemblies into electronic equipment cabinets. Specific industrial assembly requirements and process outcomes were addressed in the curriculum design. The statistical analysis of the quantitative data indicated there was a statistically significant outcome associated with the proximal treatment of the repair hours data set. However, the applied treatment did …

Children of today are gaining exposure to electronic reading environments at earlier ages and in greater frequencies than prior generations, as evidenced by the ubiquity of modern technologies. Such technologies provide affordances beyond basic text by supporting the screen-based rendering of aural, visual, and gestural elements. This research investigates, by way of a fixed effects meta-analysis, the overall effect of electronic reading environments on the comprehension outcomes of children between the 4th and 8th grades. Findings yielded three published studies between 2016 and 2020. Results from a total population sample of 2,125 students across the United States, showed small but significant effects of reading technology on comprehension. The implications of these findings are discussed in light of their pedagogical applications and future research directions.

The evaluation of the transition experiences of veterans to civilian life was conducted. The military to civilian transition (MCT) framework along with theories covering organizational, identity, and systems streams of research situated the study. A mixed methods approach was conducted in two phases: a 28-item survey and 1.5-hour interviews, which helped contextualize and explain survey findings. The multiple regression procedure examined the relationship among three variables: person-organization fit, military identity, and organizational commitment with military identity was included as a moderator. Results indicated a positive relationship between person-organization fit and organizational commitment. Contrariwise, results indicated military identity's relationship between the variables was found to be not statistically significant. Although the moderation effect of military identity was not found to influence the relationships, interviews with veterans indicated a strong connection to their military identity. Veterans shared negative and unpredictable transition stories, positive transition stories, feelings of isolation, and held prevailing military goals, while reporting a lack of backing from support agencies. Veterans perceived differences between the military and civilian environments, veteran turnover and organizational commitment were found to connect and military values and military identity were found to have connections as well. Recommendations for improving military to civilian setting transitions for …

Online and hybrid onboarding, or new-hire training and assimilation, has grown increasingly common in corporate settings, especially since the COVID-19 pandemic. This study explores how perceived onboarding experience, work locus of control, occupational self-efficacy, and employee engagement differed between those who onboarded with in-person, hybrid, or online methods. This study also explores how work locus of control could moderate these relationships and examines the relationships between employee engagement and onboarding experience, locus of control, and self-efficacy. This study used quantitative research methods in the form of a self-administered online questionnaire aimed at corporate employees who had onboarded within the previous 18 months. One hundred fifty-three employees completed the survey. It was found that no significant difference in the variables existed between modalities, except for the task characteristic subscale of perceived onboarding experience in which scores were lower for those onboarded in-person. However, work locus of control was found to significantly moderate the relationships between onboarding modality and experience, locus of control, and self-efficacy. Additionally, employee engagement was increased with higher perceived onboarding experience, more internal loci of control, and higher self-efficacy. In addition to the research questions, demographic data were also explored. It was found that perceived onboarding experience was …

The purpose of this quantitative study was to further explore pedagogical balance using multidimensional scaling and epistemic network analysis. Teacher shortages and attrition remain a critical issue for the future, and simulated classroom environments like simSchool can provide teachers additional training to help improve teaching confidence and teaching experience. Two different data sets were analyzed at various time before and after simSchool use to see how pre-service teachers rate themselves in 8 areas of teaching as defined by the Survey of Teaching Skills. Multidimensional scaling was utilized to see how teaching confidence and teaching experience align with no simSchool use, 90 minutes of use, and 8 hours of use. Epistemic network analysis was utilized to look at the cognitive structures of different groups to determine any differences. The findings are discussed with future research directions provided.

Secondary English as a Second Language (ESL) students commonly face obstacles that put them at greater risk for learning gaps in computer assisted learning (CAL). These obstacles include but are not limited to computer attitudes, computer self-efficacy, digital empathy, and connectivity gaps. Student attitudes towards computers as learning devices play an important role in reducing learning loss. This study intended to identify the underlying causes of ESL learning gaps in CAL by studying students' attitudes toward computers as learning tools. The study used a mixed method approach by collecting self-reported data from the Computer Attitude Questionnaire (CAQ) to compare ESL students verse native English-speaking students' computer attitudes. Three hundred sixty-nine secondary students successfully completed the CAQ for the purpose of this study. Of the eight subscales, four produced statistically significant findings. These include Computer Enjoyment (J), Empathy (E), Computer Anxiety (CA), and School Enjoyment (SC). Demographic factors were also analyzed which found that female ESL students have higher levels of empathy compared to their male counterparts. Additionally, 9th grade students reported better study habits and an increased perception of computer importance. Each of the subscale findings along with demographic factors, and qualitative results showed that ESL students are at a …
