This dissertation uses a three-manuscript style, and the ultimate purpose was to support critical thinking teaching in K-12 education from a systematic view concerning the lack of critical thinking in the young generation. The three manuscripts included in this dissertation were entirely or partly adapted based on three published or submitted research papers. The first research paper is a literature review article with an introduction to a development framework of nine principles, which provided a new view to developing critical thinking in younger children based on conceptual understanding of critical thinking. The second research paper is a study I coauthored with J. Michael Spector, which calls for more attention to the development of human intelligence given the rapid development of artificial intelligence and proposed that developing inquiry and critical thinking is a key to develop human intelligence. The third research paper reports an investigation over middle school educators' conceptualization of critical thinking and its alignment with the established theory and research. The major purpose was to connect the established theory and research with educational practices regarding what critical thinking constitutes. The significance of this study is to reveal the issues behind the abstract understanding of critical thinking and address the …

Middle America is dying. The United Nations reports the average number of deaths per 1,00 population in the U.S. has steadily increased an average of 1.2 per 1,000 persons annually since 2015. Existing research offer conflicting theories regarding the factors influencing the phenomenon. the purpose of this study was to examine reliable and valid secondary data to determine if statistical evidence exists to support the prevailing theories. Statistical evidence was observed that suggests the crude death rates among U.S. non-Hispanic white (NHWs) populations was significantly higher than other U.S. population segments between 2015 and 2018. Statistical evidence was also observed that suggests U.S. NHWs sought ambulatory services for alcohol and drug use self-injuries at higher rates than other U.S. population segments. However, the evidence suggest that U.S. NHWs are not more likely to experience earlier than expected deaths from excessive alcohol or drug use than other U.S. population segments. The study's implications are that U.S. policy makers should consider long-term economic development and sustainability strategies focused on the promotion of higher education as a deterrent to self-harm among U.S. residents without college degrees or skills certifications. The study recommends future large-scale quantitative, qualitative, and mixed-use studies that examine the micro, …

The purpose of this study was to identify the essential competencies for entry-level management positions in the food and beverage (F&B) industry based on the perspectives of Taiwanese industry professionals across three groups: work experience in Taiwan and/or mainland China, two F&B sectors (Hotel F&Bs and restaurants), and three management levels (first-line, middle, and top). A total of 515 Taiwanese F&B industry professionals participated in this study with 104 participants currently employed in mainland China, some of whom worked previously in Taiwan, and 411 participants working in Taiwan, without work experience in mainland China. Factor analysis produced four dimensions of important competencies: leadership, F&B management, interpersonal skills, and communication skills. Results indicated that communication skills was the only dimension that showed significant difference between participants with and without work experience in mainland China. The findings of this study indicated that 14 of 41 competency items were ranked in the top 10 based on the responses of the three groups. Participants from all three groups ranked "high level of personal integrity" as the most important competence and "ability to communicate orally in proper English" was ranked as the second most important competence by all groups except the restaurant sector. The results …

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.

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 …

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 convergent mixed method study was to determine whether or not there is a difference in the perceived and actual financial literacy scores of millennials. Exploring the following research questions and hypotheses helped to expand knowledge around actual financial literacy and several other characteristics, including perceived financial literacy, especially among millennials (individuals born between 1981 and 1996): RQ1: What is the difference between millennials' actual and perceived financial literacy scores? RQ2: To what extent do socioeconomic status, gender, and having a bank account predict millennials' financial literacy scores? H0: There is no relationship between millennials' socioeconomic status, gender, banking status and their financial literacy scores. RQ3: What video delivery methods (if any) are millennials using to gain financial literacy knowledge in informal learning environments? Millennial participants (N = 207) were asked to complete a survey. Participants' perceived financial literacy scores were higher than their actual financial literacy scores. While males had higher perceived financial literacy ratings, females accounted for the majority of participants who scored four or above on a 5-point scale for actual financial literacy. Although, the null hypothesis was incorrect, the independent variables used in the ANOVA tables accounted for less than 15% of financial …

This research study investigated associations between online community college students' personal characteristics and experiences in online courses (n = 123). Specifically, students' personalities and cognitive styles were examined alongside the perceived quality and outcomes of collaboration. Negative correlations were found between the conscientiousness personality style and both the quality of collaboration (p = .09) and the outcome of collaboration (p = .05). This finding indicates that conscientious students who, according to the literature tend to have higher academic achievement than other students, perceive negative experiences in online collaborative environments. Conversely, a positive correlation was discovered between the extraversion personality type and the perceived outcomes of collaboration (p = .01). Thus, students with a strongly extraverted personality tend to perceive that they benefits from collaborative learning. Approximately 11% of the variance in the collaborative experience was explained by the combined personal characteristics. The reported frequency of collaboration was positively correlated with both the quality (p < .01) and the outcomes of collaboration (p < .01). While not generalizable, these results suggest that not all students perceive benefits from online collaborative learning. It may be worthwhile to teach students traits associated with the extraversion type like flexibility which is important for collaborative …

This study aimed to observe measurement invariance between community college students and university students in response to the Community of Inquiry (CoI) Survey instrument. Most studies of the CoI survey instruments have recorded and validated the instruments considering undergraduate or graduate students. This study sought to validate and prove the survey tool as a reliable instrument for the community college population. The study employed SEM and meta-analytic procedures to observe measurement invariance between a Monte Carlo generated general university sample population and the community college survey population. The findings are discussed, as well as the implications for CoI studies in the community college.

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 …

Open online courses provide a unique opportunity to examine learner preferences in an environment that removes several pressures associated with traditional learning. This mixed methods study sought to examine the pathways that learners will create for themselves when given the choice between an instructor-directed modality and learner-directed modality. Study participants were first examined based on their levels of self-regulated learning. Follow-up qualitative interviews were conducted to examine the choices that participants made, the impact of the course design on those choices, and what role self-regulation played in the process. The resulting analysis revealed that participants desired an overall learning experience that was tailored to personal learning preferences, but that technical and design limitations can create barriers in the learning experience. The results from this research can help shape future instructional design efforts that wish to increase learner agency and choice in the educational process.

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.

This study investigates the effectiveness of an inquiry-based learning curriculum for middle school students with learning and/or attentional disabilities (LD and/or ADHD). The main questions asked were: To what extent can an inquiry-based learning curriculum focused on digital responsibility impact: (1) well-being; (2) smartphone usage; and (3) smartphone awareness among adolescents with LD and/or ADHD? Fifty middle school participants with LD and/or ADHD were divided into two groups, an experimental group and a control group. Findings showed a significant increase both in positive affect and in awareness of personal smartphone usage for experimental, but not control, participants, suggesting that inquiry-based learning may be an effective approach for teaching digital responsibility to students with LD and/or ADHD. Other findings indicated that social connectivity is a high priority for today's adolescents. Additional insights and implications are discussed.

The purpose of this quantitative study was to provide a valid and reliable instrument that can be used to collect radiologic science faculty members' perceptions of online education. Using a survey modified from an existing study, data were collected concerning faculty perceptions of online education in radiologic sciences. R was used to analyze the survey data through exploratory factor analysis, confirmatory factor analysis, short form optimization, and weighted multiple regression analysis to produce an instrument that exhibits both content and construct validity, is reliable, and is a shortened, optimized version of the original instrument. The findings are discussed and recommendations for future research are provided to begin work broadening this under-researched area in the field of radiologic sciences.

The purpose of this exploratory study was to investigate the relationship between the digital divide and the Latino-White achievement gap in online education. Through an analysis of archival enrollment and academic performance data a comparison was conducted between online and face-to-face courses by ethnicity. Additionally, academic performance data was then compared to survey responses from online students on digital motivation, material access, internet skills, and internet usage. Findings and recommendations for future research are discussed and provided to continue the exploration of disparities of digital access and academic performance in an effort to inform decisions in higher education.

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 research was to examine ESL (English as a second language) students' current use of their mobile phones for English skill building activities outside of class in a U.S. school setting. In addition, this research reported on students' perceptions of the potential benefits of using smartphones in class for English learning. Also learners' current English related activities using mobile devices and time duration of using different phone features were studied. The literature review included smartphones, computer education, mobile learning, mobile assisted language learning (MALL), computer assisted language learning (CALL), theories of second language learning, second language learner attributes and the use of smartphones outside the classroom. An electronic survey was used to collect the quantitative data which were analyzed by descriptive and inferential statistics. The results concluded that students used mobile applications on a daily basis to read and write email, read books and news, check a dictionary, talk, text and video chat. Students used mobile phones outside of class to improve the English skills listed in the survey and the same participants perceived the potential benefits of using smartphones in class for the same English skills. Among the English skills, vocabulary exercises, finding example sentences of …

Work-based and employee-driven informal learning, training and development have been increasing in importance in the last few decades. Concurrently, organizations seek to measure the extent to which they develop a culture and structure that supports individual learning and organizational learning. This study develops and validates a scale that can measure the extent to which an organization is perceived to provide online learning that is personalized for its employees and perceived to recognize skills and competencies acquired through non-degree and other pathways. This research can provide organizations with the ability to measure and benchmark attributes of their learning culture that are important to work-based and lifelong learning as well as talent recruitment and management.

Online courses in higher education have a reputation for having a lower course completion or retention rate than face-to-face courses. Much of this reputation is based upon anecdotal evidence, is outdated, or is on a small scale, such as a comparison of individual courses or programs of instruction. A causal-comparative analysis was conducted among 11 large, high research public universities. The universities were compared to each other to determine if differences existed between online and face-to-face course completion; undergraduate and graduation online course completion was analyzed for differences as well. The findings suggested the magnitude of the differences between online and face-to-face completions rates was small or negligible. The area which showed a higher magnitude of difference was in the comparison between undergraduate and graduate online course completion; the practical significance could be worth considering for educational purposes.

This study explored the effectiveness of a student question creation process engaging students actively in self, peer, and instructor interaction in development of affective, cognitive, and meta-cognitive skills. Employing a mixed-methods sequential explanatory design assigning both treatment and control activities sequentially in an alternating pattern over a six week period, students' performance on exams as well as their perceptions of various aspects of the student question creation process were used to evaluate the effectiveness of student-created questions (SCQs) activities as a cognitive strategy and to identify factors contributing to the effectiveness of question creation activities on students' learning. Subjects of this study were high performing and highly motivated graduate students in an 8-week online biomedical statistics course, part of a specialized master's program designed for medical school preparation. Survey findings and focus groups strongly supported the student question creation process as a facilitator of higher order thinking. However, the relatively short study duration, comparison of student question creation with another competing method for facilitating learning (discussion board) and not a pure control group, and availability of a common study guide course with student-created questions on all course topics may have muted assessment of the full impact of the strategy on …

Individual personality traits of pre-service teachers may have a significant influence on their confidence in teaching. Confidence in teaching does not always align with the experience of pre-service teachers. simSchool enables transformational experiences for teacher candidates to improve in general teaching skills, connect learning theories in the classroom, and develop confidence to be an effective teacher without the ill impacts of practicing on real students. This study executed a quasi-experimental design to explore the personality traits of 152 pre-service teachers and examined how their perceptions of teaching confidence and teaching experience were related in the context of simSchool. A treatment and comparison group completed the Survey of Teaching Skills pre/post tests and the OCEAN survey for quantitative data analysis to investigate four research questions: 1. Is there a difference between treatment and comparison groups on educator’s gains in confidence and experience? 2. Is there a relationship between personality type and perceived teaching effectiveness? 3. Is there a relationship between personality attributes and pre-service educator ratings of teaching experience in a simulated teaching environment? 4. Is there a relationship between personality attributes and pre-service educator ratings of teaching confidence in a simulated teaching environment? Findings from repeated measures MANOVA tests indicated …

Educational video games have proven a useful tool for educators, offering experiential pedagogy in a variety of fields. Predicting the success of a video game in engaging students and motivating them to work with relevant material is problematic. One approach was attempted through administering the Myers-Briggs Personality Type Indicator to 42 high school students and observing subsequent voluntary performance on a popular mathematics video game throughout one semester. Game dynamics matching certain personality elements of the students generally correlated between learning preferences in the classroom and in the online gaming environment. Students who enjoyed group dynamics in classroom settings likewise indicated enthusiasm for the group dynamics in game play. Those students preferring structured learning environments may prefer less open ended virtual learning gaming environments. Since the game incorporated multiple choice questions and rewarded correct choices made quickly, those students with personality styles in which questions are carefully considered before answering suffered in points scored compared to those used to making fast intuitive choices in exam settings. Additional studies, including those with larger populations and different types of video games, are needed for more definite conclusions.

Are our students just consumers of technology or do their interests in technology translate into positive perceptions about STEM majors and careers? This research aimed to describe the role of the Internet in undergraduate students’ academic and career perceptions in STEM areas. The purpose of the research was addressed in three parts. First, the attitudes of undergraduate students towards five functions of the Internet namely tool, toy, treasure, telephone and territory were described. Second, students’ STEM career-related perceptions were described in terms of their science and mathematics self-efficacy, outcome expectations, and attitudes towards a STEM career. Third, the relationship between the five Internet functions and the three STEM career-related perceptions was examined. The participants for this study were 566 undergraduate students from a large Southern university. The research design followed a mixed methods approach using multivariate analyses and content analyses. The findings of the research indicated that there was a small but meaningful relationship between undergraduate students’ Internet and STEM perceptions. In their daily lives, the students perceived the Internet more as a toy and a tool. For general career related purposes, they perceived the Internet more as a treasure and a tool. For STEM areas in particular, they perceived …

The focus of this study was to conduct a meta-analytic investigation to combine the results obtained in independent studies aimed at determining the effectiveness of using digital games, as opposed to traditional methods, as a strategy for improving students' performance in high school mathematics. The major question of this study is: "Does the research on the use of games in high school mathematics support the use of games as a teaching strategy for improving student achievement?" To answer this question, meta-analysis was employed. Meta-analysis synthesizes and analyzes the quantitative data collected in independent and multiple empirical studies carried out on similar topics, situations, and hypotheses in order to reach a general judgment regarding the results of these studies. To determine which studies to use, specific criteria including articles published in refereed journals, thesis, and dissertation studies with experimental and control groups, research with effect size, sample size, standard deviation, and means. Based on these criteria, it was decided to include six experimental studies in the meta-analysis. The result showed that there was no significant differences between the use of digital games and traditional methods to teach mathematics in high school. The weighting factor of the two variables, standard deviation and …
