With the fast growth of online education, factors influential to course completion need to be examined. Statistically, this study explored the relationship between five course status factors identified in the literature and the completion of previously incomplete online courses in a course-based approach. The five factors were about the curricular and completion status of an online course with an initially assigned "Incomplete" grade, including credit hours, required assignments, initially submitted assignments, initially earned points, and duration of incomplete status. The extent of coursework completion was measured by the subsequently completed assignments and subsequently earned points. Online courses (n = 933) offered with the 15 different course titles in an online graduate degree program and assigned an "Incomplete" grade in their registration terms between fall 2001 and fall 2005 were used as the units of data analysis. Multiple regression, logistic regression, descriptive statistics analyses, Chi-square tests, and independent t-tests were used for the statistical analysis. The results showed that there were significant differences (a = .05) in the required assignments, initially submitted assignments, initially earned points, and duration of incomplete status between the courses that were completed eventually and those that remained incomplete. According to the statistically significant results, the set of the five course status variables could explain 93.6% of the variance in the completion measured by the subsequently completed assignments and account for 87% of the variance in the completion measured by the subsequently earned points. The statistically significant results also indicated that the set of the five variables could be used to predict the probability of the coursework completion. Regarding the individual variables, the statistically significant results identified the required assignments and initially submitted assignments as the factors contributing to the explanation of the variance in the coursework completion measured by the subsequently completed assignments; the credit hours, required assignments, initially earned points, and duration of incomplete status as the factors contributing to the explanation of the variance in the coursework completion measured by the subsequently earned points. The required assignments and duration of incomplete status were identified as significant predictors of the completion. / Ph. D.

The purpose of this study was to examine whether there are significant relationships between the general satisfaction of students and learner-content interaction, learner-instructor interaction, learner-learner interaction, and learner-technology interaction in 100% online courses. There were 310 responses from the students. This study did not use data from duplicate students and instructors. Excel was used to find duplicate students and instructors; therefore, 128 responses were deleted. After examination of box plots, an additional four cases were removed because they were outliers on seven or more variables. Nineteen responses were deleted because they did not answer all questions of interest, resulting in a total sample of 159 students. Multiple regression analysis was used to examine the relationship between the four independent variables and the dependent variable. In addition to tests for statistical significance, practical significance was evaluated with the multiple R2 , which reported the common variance between independent variables and dependent variable. The two variables of learner-content and learner-instructor interaction play a significant role in predicting online satisfaction. Minimally, the variable learner-technology can predict online satisfaction and is an important construct that must be considered when offering online courses. Results of this study provide help in establishing a valid and reliable survey instrument and in developing an online best learning environment, as well as recommendations for institutions offering online learning or considering the development of online learning courses.

Given the competing contexts of teacher education, it is important to uncover what teacher educator knowledge concerning curriculum design and development emerges in design, implementation, and instruction during the transition from in-person to online contexts. Yet, there is little research that uncovers teacher educator knowledge in curriculum making generally, and more specifically, how this knowledge is carried forward or changed as teacher educators create and enact online teaching. Because transitions are an important time to uncover tacit and embodied understanding, in this self-study of teacher education practice (S-STEP), I examined my own teacher educator knowledge during planning, teaching, and reflecting as I shifted to teaching online. Seven strands of teacher educator knowledge were represented in analytic narrative vignettes and identified as knowledge of content, fixed and fluid elements of course design, milieu, pedagogical intent, preservice teacher knowledge and belief, the value and fragility of relationships, and theory. Then I examined each of the strands separately as a way to discuss findings more holistically. By shifting the teaching context, I questioned and deepened my knowledge of preparing preservice teachers. Further, the analysis revealed how these seven strands of my teacher educator knowledge were interconnected, made stronger, and interacted differently during the stages of planning, teaching, and reflecting. Such intimate study of my own teacher educator knowledge revealed my obligations, responsibilities, and commitments to preservice teachers and the students they will teach. Studies that examine the shifts in teaching context have the potential to identify and highlight the complexities of teacher educator knowledge, thereby making a useful contribution to the research conversation in teacher education. By recognizing and naming their teacher educator knowledge, teacher educators can sharpen and improve their practice as they design courses, especially including improvements in online teacher education, participate in constructing programs, and defend their programs in accreditation processes.

The problem addressed in this study was that the Compass Learning Odyssey program, a self-paced online intervention, was being utilized to allow middle school students at the target school to recover course credits in the core subjects of language arts, mathematics, science, and social studies, but its effectiveness had not been studied. The Compass Learning Odyssey program provided remediation opportunities for students who had failed one or more academic core courses and allowed for credit retrieval, course completion and grade promotion. The purpose of this study was to determine the impact of the implementation of summer credit retrieval online program on the overall retrieval of credits by all Grade-8 student participants and student participants in subgroups of gender and ethnic groups. The credit retrieval program had been in effect in the school since the 2006-2007 school year, but its effectiveness had not been studied. The researcher used de-identified retrospective data to answer the research questions. One-way analysis of variance and t tests were conducted to determine for each year and overall for the 4 years if there was a statistically significant difference in the impact of the implementation of the summer credit retrieval online program on (a) the overall retrieval of credits by Grade-8 students in the summer program, (b) the quality points earned by gender and ethnic subgroups, (c) the students retrieving core credits, and (d) the core courses retrieved by gender and ethnic groups.The results of the study showed that all students passed the quarter modules with at least a grade of D, with 75% of students making average progress with a grade of C. There was not a statistically significant difference between subjects studied. Ninety-three percent of the students participating in the summer credit retrieval program were able to recover enough core credits to be promoted. Suggestions for program improvements and recommendations for future research are included.

The purpose of this study was to examine the impact of completing online diaries with specific topics on students’ self-regulated behavior in online courses. Also, this study sought to determine the impact of completing online diary topics with different topics (content-based or experience-based) on students’ self-regulation in online courses. The participants’ use of learning strategies was assessed to aid in this investigation. The research design utilized for this study was a quasi-experimental pretest/posttest design. The participants of this study included 30 undergraduate students from a variety of majors who were enrolled in one of two online courses. Of the 30 participants, 15 of the participants were in the content-based treatment group while the other 15 were in the experience-based treatment group. Convenience sampling was used to recruit participants for this study. Using data collected from the Motivated Strategies for Learning Questionnaire (MSLQ) and the diary entries submitted by the participants, the researcher did not find associations between completion of online diary topics and participants’ self-regulated behavior within the online courses. However, results did indicate that the content-based group reported higher levels of critical thinking usage than the experience-based group after the treatment was administered.

Devry University, a private for-profit higher education institution, generates its revenue exclusively by students* tuition. In addition, DeVry University offers courses via two modalities: blended and online. Unfortunately, Devry University has seen its student enrollments decline over the last few years. Because of lower student enrollment levels, DeVry University has had to limit its course offerings. The problem of practice addressed in this dissertation is an insufficient number of blended course offerings for current DeVry students. To remedy this problem, an initiative was started at DeVry University to address the insufficient number of blended course offerings and to pilot a new course modality, cross-listed (C-L) courses, in the March 2014 session at four campus locations. More specifically, this initiative involved offering several sections of CIS115 (Logic and Design with Lab) in its C-L modality. C-L courses combine students registered in more than one modality: in this case, blended and online modalities. Upon completion of the pilot offering of C-L courses, an evaluation was conducted to determine if the new C-L modality had a positive impact on addressing the stated problem of practice. This evaluation used an outcome-oriented post-test only design with non-equivalent groups (quasi-experiment) coupled with qualitative components. The quasi-experiment compares outcomes of students enrolled in C-L courses (the treatment group) with students enrolled in blended and online courses (comparison groups) using post-achievement data. The results of the evaluation revealed that students who completed the C-L CIS115 courses performed as well as students who completed blended or online CIS115 courses, considering their course satisfaction levels and course outcomes. Professors* perceptions of the C-L modality were also analyzed; results indicate that professors are willing to endorse the new modality but not without suggesting some improvements. The evaluation also revealed that there was an increase in the number of blended courses offered at DeVry University campuses, suggesting that the problem of practice may be addressed by this initiative. Recommendations for further studies include repeating the pilot offering in the C-L modality, with the inclusion of professors* suggestions for improvement identified in this study. These improvements include providing campus-based professors with an ability to broadcast and record their classroom lectures for the benefit of all students enrolled in C-L courses.

Lecture recording has become an essential tool for educational institutions to enhance the student learning experience and offer online courses for remote learning programs. Highresolution 4K cameras have gained popularity in these systems due to their affordability and clarity of written content on boards/screens. Unfortunately, at 4K resolution, a typical 45- minute lecture video easily exceeds 2GB. Many video files of this size place a financial burden on institutions and students, especially in developing countries where financial resources are limited. Institutions require costly high-end equipment to capture, store and distribute this ever-increasing collection of videos. Students require a fast internet connection with a large data quota for off-campus viewing, which can be too expensive for many, especially if they use mobile data. This project designs and implements a low-cost presenter and writing detection front-end that can integrate with an external Virtual Cinematographer (VC). Gesture detection was also explored; however, the frame differencing approach used for presenter detection was not sufficiently robust for gesture detection. Our front-end is carefully designed to run on commodity computers without requiring expensive Graphics Processing Units (GPU) or servers. An external VC can use our contextual information to segment a smaller cropping window from the 4K frame, only containing the presenter and relevant boards, drastically reducing the file size of the resultant videos while preserving writing clarity. The software developed as part of this project will be available as open source. Our results show that the front-end module is fit for purpose and sufficiently robust across several challenging lecture venue types. On average, a 2-minute video clip is processed by the front-end in under 60 seconds (or approximately half of the input video duration). The majority (89%) of this time is used for reading and decoding frames from storage. Additionally, our low-cost presenter detection achieves an overall F1-Score of 0.76, while our writing detection achieves an overall F1-Score of 0.55. We also demonstrate a mean reduction of 81.3% in file size from the original 4K video to a cropped 720p video when using our front-end in a full pipeline with an external VC.
