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 study explores the phenomenon of computational thinking indicated by the use of Bloom's taxonomy's cognitive domain verbs in the Scratch community, the online, collaborative environment for the Scratch Visual Programming Language (VPL). A corpus of 660,984 words from three Scratch community sub-forums provide the data for this study. By semantically aligning cognitive domain verbs of Bloom's revised taxonomy to computational thinking (CT) dimensions, the occurrences of the verbs in Scratch community sub-forums are used to indicate instances of computational thinking. The methodology utilizes qualitative coding and analysis with R® and RStudio®. The findings show language attributes such as expressions of imagination, sharing of creative details, collaborative development ideas, teaching, modeling, innovating, solutions focused, and technical support to be indicative of computational thinking and CT dimensions. The computational thinking dimension referred to as computational perspectives occurs most frequently within Scratch community participant discourse. The environmental factors found to contribute to computational thinking and the CT dimensions are supporting tools, personalized learning, supportive organizational culture, social learning, and organizational support. Common among the three computational dimensions is the contributing environmental factor described as supportive organizational culture, with the computational perspectives dimension prevailing among the corpora. The characteristics of computational perspectives and …

This dissertation seeks to determine the differences between veteran and non-veteran students' mental effort and task difficulty within undergraduate online courses in Bachelor of Applied Arts and Sciences (BAAS) programs at three public Texas universities. The BAAS program is geared toward non-traditional students, which includes veterans. The courses are delivered in flexible formats, including online courses, face-to-face courses, and blended courses, which use a combination of online and face-to-face courses. After reviewing literature and utilizing both the cognitive theory of multimedia learning and the cognitive learning theory, a survey was conducted using undergraduate students enrolled in BAAS programs at three public Texas universities. The data was analyzed by conducting a factorial ANOVA and Pearson correlation to determine if there was a difference between veterans and non-veteran students' mental effort and task difficulty within online courses within the BAAS programs. The results indicated that that all three hypotheses failed to reject the null hypotheses that: (1) there is no difference in mental effort of students who had military service, versus those who did not have military service, (2) there is no difference in mental effort of students who had military service, versus those who did not have military service, and (3) …

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, …

This case study investigated the phenomenon of the black white test score gap by seeking to determine if there was a difference in the academic performance of African American students and their White peers. The determination of student academic performance was made using scores from second semester Algebra II classes at two high schools in the Tucson Unified School District. The data covered three academic years and was analyzed via SPSS (independent samples t-test, ANOVA, and a pairwise analysis) and content analysis for qualitative analysis. Findings revealed that there was no variance in the scores of African Americans and their White peers attending an affluent school; however African Americans attending a low-income school scored lower than all groups that were compared in this study.

A case study was used to survey 308 teacher trainees in western Kenya to investigate the extent to which pre-service teachers in two Kenyan teacher training colleges are prepared to integrate technology in teaching. . The study uses the technological pedagogical and content knowledge (TPACK) framework to understand the knowledge needed by the pre-service teachers to integrate technology effectively. Data was gathered using the Survey of Pre-Service Teachers' Knowledge of Teaching and Technology and three open-ended questions. Data from the survey does not distinguish the TPACK variable among the respondents. The data suggests that the pre-service teachers rate themselves highly on the other six TPACK subscales of technological knowledge, content knowledge, pedagogical knowledge, pedagogical content knowledge, technological pedagogical knowledge, and technological content knowledge. Further, the data suggests that the respondents' personal use of technology, to a large extent, influences how they use technology in classrooms. Lastly, the data indicates that the survey instrument is inadequate in capturing all the TPACK subscales in this population as it shows weak internal consistency. These findings imply that faculty in these colleges need to be more intentional and deliberate in teaching the trainees how to integrate technology in lessons. Policymakers and college administrators may …

The current study was conducted with foreign language students enrolled in the summer course at Middlebury Institute of International Studies (MIIS), an intense foreign language program. The study measured and analyzed students' preferences toward mobile applications for learning a foreign language. Survey questionnaires were used to collect data on students' preferences of mobile delivery modes for learning a foreign language. The research design deployed was single-case design at two points-in-time, called repeated measures design in the t-test statistics, where effects-over-time of treatment (i.e., using a technological device) were tracked. The effects-over-time of using a mobile device for learning foreign language skills were significant and the magnitude of differences in students' attitudes between Weeks 2 and 8 was also significant. Students must have felt that their performance had changed at Week 8 and that using a smartphone could have been the difference. The structure and the research methodology of having null hypotheses that are tested statistically are both clear enough to provide a template for a replication of the study with a different sample. The statistical tests used by this study can be replicated with different research problems or a different audience.

This meta-analysis looks at the results of five studies on the use of technology for the treatment of dyscalculia in primary school age children. Results show significant positive improvement using specialized software treatment technologies for students in Grades 1-5 in various countries using four different software games. However, little is known overall about the effectiveness of technology treatments for dyscalculics, and even less is known about standardized assessments and treatment of this learning disorder in the United States. The literature researched for this dissertation did not put forth any known policies that drive assessment and treatment of dyscalculia. Future studies are needed about dyscalculia, that provide more detailed information to allow other researchers to verify their work.

During the COVID-19 pandemic in the spring of 2020, universities throughout the United States closed their campuses and transitioned their face-to-face courses to remote learning. The unprecedented transition created a unique learning and teaching environment. This case-based qualitative study investigates the experiences of business professors from a prestigious school of business that taught during the transition. Findings derived from the digital Likert survey instrument completed by all the business faculty and semi-structured interviews of selected business faculty. Some of the topics of the survey and interviews included communicating with students, developing the learning management system course content, delivering asynchronous material, delivering synchronous classes, and providing instructional feedback. Findings included a significant growth in business professor's perceived skillset in almost all topics, an interest in further developing skills, and an interest in adopting the new skills in future face-to-face courses. Through NVIVO analysis of the interviews, four thematical elements were identified: faculty efficacy, faculty training, course delivery, rapport. The study investigated a deep wholistic view of the data presented and provided an extensive in-depth description of the social phenomenon. A practical framework for incorporating the identified themes was developed for business schools needing to establish and maintain online business programs.

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 …

In the current globalizing society, teachers are provided opportunities to move across their national borders to seek learning, professional development, and working opportunities. Technology-related professional development is particularly valued for teachers' sojourn to the technology intensive cultures. This qualitative cross-case study explored the K-12 Chinese language teachers' changes of teachers' application and perspective toward educational technology in cross-cultural teaching context through the lens of transformative learning theory. The qualitative data is collected from the interviews with 20 teacher participants in the four stages of cross-cultural sojourning: pre-departure, currently sojourning, post-sojourn, and immigrated. A qualitative cross-case analysis is conducted to compare the characteristics of teachers in different cases, and developed the complete process of the cross-cultural technology adoption and perspective. Factors contributed to the changes are also identified. Five issues related to the process are discussed. Implications and future directions were also included.

This study investigates the effects of sketchnoting, a visualized approach of notetaking, on learning strategies. The main questions asked were: What are the effects of sketchnoting on learners' learning strategies, including cognitive strategies (rehearsal, elaboration, organizational) and metacognitive strategies? Forty-eight undergraduate participants were divided into two groups, an experimental group, and a control group. Findings demonstrated a significant increase in cognitive learning strategies and metacognitive strategies in the experimental group. Other findings revealed that the aesthetic appeal of sketchnoting is the major reason motivating participants' sketchnoting behavior and the corresponding connection between design strategies and the learning strategies is the key of positive impacts of sketchnoting on learning strategies. Additional insights and implications are discussed.

Companies are becoming increasingly dependent on teams to drive creativity and innovation, which usually involves multiple teams working together to solve complex problems However, the first problem is that work teams do not always manage creativity and innovation well, especially when partnering with other work teams on highly complex projects that demand greater interdependence and collaboration, which can constitute as much as 90% of today's organizational projects. The second problem is that researchers struggle to define and measure creativity and innovation for the past decade resulting in significant variation both within and between creativity and innovation scales that have restricted meaningful theoretical discoveries and advances. The current study is significant because it introduces a novel instrument derived by John Turner that measures team creativity and innovation processes as a single unit, thereby raising the level of theoretical sophistication and leading to better practical applications. After conducting factor analysis, the current study validates six factors, including 36 indicators, and measures team creativity and innovation processes as complex adaptive systems (CAS). The current study recommends deploying the new instrument in other sectors beyond the IT sector and using multilevel techniques that include the individual and executive/organization levels of analysis.

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 …

MakerBuses are travelling makerspaces that deliver hands-on tools and resources to community-wide locations to foster 21st century learning and development. Often found in K-12 schools, MakerBuses provide accessible and tangible learning opportunities for all learners, even in the most underserved communities. This single, typical case study provided a foundational look at how one MakerBus started as a simple idea and evolved into a learning experience used throughout the community it serves. Through discovery it was evident that accessibility, community outreach, tool distribution, and active learning were the critical elements that made this makerbus a unique tool for education.

The COVID-19 pandemic wiped off decades of educational gains in the developing world and added 24 million more children to 775 million illiterates in the world. To counteract such a huge predicament, human learning agility comes into action. This human characteristic of knowing what to do when one does not know what to do, invokes the Soft System Methodology (SSM) approach to analyze illiteracy as the worst of all pandemics since it infiltrates into generations. After evaluating different effective teaching methods and utilizing the SSM approach, this paper proposes suitable pedagogies to educate deprived students. It examines Massive Online Open Courseware (MOOC) as a viable solution for K-12 students and compares it with a more robust educational technology model of Intelligent Tutoring System (ITS). Using artificial intelligence, the ITS tailors the instructional content framework and teaching strategies after evaluating students' pre-existing knowledge, learning habits, & styles. The ITS engages the student with the lesson with a two-way dialog while providing customized instruction and immediate feedback. An ITS requires no human intervention and could be a suitable replacement for an inadequately qualified teacher or no teacher. Hence it could be a practical tool in tackling the global literacy catastrophe. A comprehensive …

The objective of this study was to locate and describe the learning affordances used within research studies on instructional design. Allowing an instructional designer to see what was used and how applicable it might be for future design would assist with better course creation. Current and past literature supported the importance of this concept after examination of how course creation has evolved within the field of instructional design. Further, the findings elucidated how to help the field evolve in the future by expanding knowledge about learning affordances and providing the broadest set of conceptual definitions by the academics working in the field to include them in their research and instructional designs.

This mixed methods study examined teacher attitudes towards technology and their relationship to the integration of technology in technology-rich learning environments.

As technologies for learning become increasingly available in K-12 schools, the role and responsibilities of campus principals continue to evolve. Incorporating technologies in schools requires shifts in practices, the development of new skills, and in some cases, changes in the mindset of stakeholders. Schools should be capable of absorbing the knowledge and creating the systemic structures required for the implementation ICTs. The purpose of this study was to research the principals' perspective to lead the implementation of ICTs for learning in public schools. As campus leaders, principals are increasingly required to support the utilization of ICTs for classroom instruction. It is of particular importance, therefore, to study and explore the needs school principals identify to lead the implementation of technologies for learning. More specifically, the goal was to gather relevant data to analyze topics that campus principals believe positively and negatively influence the implementation of ICTs in schools.

The goal of learning analytics is to optimize learning and the environments in which it occurs. Since 2011, when learning analytics was defined as a separate and distinct area of academic inquiry, the literature has identified a need for research that presents evidence of effective learning analytics, as well as, learning analytics research that is conducted in conjunction with learning theory. This study uses Efklides' metacognitive and affective model of self-regulated learning (MASRL) to define cognitive, metacognitive, and affective variables that can explain students' learning outcomes in hybrid/online sections of Calculus I in the 2020-21 academic year. Cognitive variables were measured according to the cognitive operational framework for analytics (COPA). Metacognitive variables were defined according to the ways in which students interacted with the course content in the learning management system (LMS) and supplemental instruction, and affective variables were measured by ways students gave evidence of their affective states, such as in discussion board posts. All variables were compared across the course learning design, activities, and outcomes. Binary logistic regression revealed five significant variables: two cognitive, one metacognitive, and two affective. Thus, this study provided a learning analytics, evidence-based link between self-regulated learning theory and learning design, activities, and outcomes. …

This qualitative study examines an asynchronous online course from a private university utilizing a template model for all online courses to provide students with consistent navigation and course structure throughout their degree program. The asynchronous online courses are purposely created using three criteria of quality course design: navigation is intuitive, information is chunked, and instructions are written clearly. A two-part usability test was conducted with three internal and three external participants. The two-part usability test focused on course navigation and examined the signaling, segmenting, and coherence principles applied to course content page layouts. Transcripts from the usability tests and observational field notes were coded through an iterative process in Nvivo. Through emic and etic coding, seven main categories were identified: user experience, cognitive load, multimedia learning principles, page design and layout attributes, course navigational attributes, course attributes and information, and participant navigational behavior. The findings for first-day navigation, general navigational behaviors, and perceptions of design elements used to implement the signaling, segmenting, and coherence principle are discussed. Course design recommendations for creating a positive usability experience and suggestions for future research are provided.

Many academic institutions are tasked with trying to improve the usability of their online educational support technologies such as ePortfolios, intelligent websites, and other interface technology to make them as efficient as possible to meet the requirements of their end users. This is particularly important for the academic institutions during times and situations when they may not have a live human presence available to respond to various inquiries from their end users about the technology. The challenges of an academic institution in making its ePortfolios viable can cost itself, its end users, as well as its other stakeholders, money, time, and confidence in the technology. This study is about usability testing for improving the user-interface for ePortfolios. This is a qualitative study using the think-aloud protocol (TAP) for data collection and failure modes and effects analysis (FMEA) for data analysis.

The purpose of this qualitative multiple case study is to identify and describe the perceptions and experiences of lower elementary public-school teachers in the United States teaching with educational technologies during the COVID-19 pandemic. Through a demographic survey and semi-structured interviews, teachers shared their experiences regarding the barriers they encountered teaching and learning with educational technologies in face-to-face, remote, and hybrid classrooms. The multi-phase coding process used emic and etic codes to analyze the data. This study identifies and describes the existing barriers teachers face with learning technologies in the classroom before COVID-19 and the new obstacles they have encountered due to the pandemic. The results of this study are discussed, and recommendations are provided to help researchers identify the essential supports educators need for future emergencies.
