Description
Online programming communities are widely used by programmers for troubleshooting or various problem solving tasks. Large and ever increasing volume of posts on these communities demands more efforts to read and comprehend thus making it harder to find relevant information. In my thesis; I designed and studied an alternate approach by using interactive network visualization to represent relevant search results for online programming discussion forums.
I conducted user study to evaluate the effectiveness of this approach. Results show that users were able to identify relevant information more precisely via visual interface as compared to traditional list based approach. Network visualization demonstrated effective search-result navigation support to facilitate user’s tasks and improved query quality for successive queries. Subjective evaluation also showed that visualizing search results conveys more semantic information in efficient manner and makes searching more effective.

Academia is not what it used to be. In today’s fast-paced world, requirements
are constantly changing, and adapting to these changes in an academic curriculum
can be challenging. Given a specific aspect of a domain, there can be various levels of
proficiency that can be achieved by the students. Considering the wide array of needs,
diverse groups need customized course curriculum. The need for having an archetype
to design a course focusing on the outcomes paved the way for Outcome-based
Education (OBE). OBE focuses on the outcomes as opposed to the traditional way of
following a process [23]. According to D. Clark, the major reason for the creation of
Bloom’s taxonomy was not only to stimulate and inspire a higher quality of thinking
in academia – incorporating not just the basic fact-learning and application, but also
to evaluate and analyze on the facts and its applications [7]. Instructional Module
Development System (IMODS) is the culmination of both these models – Bloom’s
Taxonomy and OBE. It is an open-source web-based software that has been
developed on the principles of OBE and Bloom’s Taxonomy. It guides an instructor,
step-by-step, through an outcomes-based process as they define the learning
objectives, the content to be covered and develop an instruction and assessment plan.
The tool also provides the user with a repository of techniques based on the choices
made by them regarding the level of learning while defining the objectives. This helps
in maintaining alignment among all the components of the course design. The tool
also generates documentation to support the course design and provide feedback
when the course is lacking in certain aspects.
It is not just enough to come up with a model that theoretically facilitates
effective result-oriented course design. There should be facts, experiments and proof
that any model succeeds in achieving what it aims to achieve. And thus, there are two
research objectives of this thesis: (i) design a feature for course design feedback and
evaluate its effectiveness; (ii) evaluate the usefulness of a tool like IMODS on various
aspects – (a) the effectiveness of the tool in educating instructors on OBE; (b) the
effectiveness of the tool in providing appropriate and efficient pedagogy and
assessment techniques; (c) the effectiveness of the tool in building the learning
objectives; (d) effectiveness of the tool in document generation; (e) Usability of the
tool; (f) the effectiveness of OBE on course design and expected student outcomes.
The thesis presents a detailed algorithm for course design feedback, its pseudocode, a
description and proof of the correctness of the feature, methods used for evaluation
of the tool, experiments for evaluation and analysis of the obtained results.

Description
The purpose of this study was to examine the effectiveness of the community of practice model in providing professional development to improve K-12 teacher’s knowledge, skills, self-efficacy with regard to the implementation of personal learning. The study also examined the extent to which the community created value for individuals and the organization. The study employed two theoretical frameworks: Bandura’s theory of self-efficacy and Wenger’s communities of practice.
The study employed a concurrent mixed methods approach. Eighteen teachers participated in a 9-month blended learning professional development focused on the implementation of personal learning. Participants took pre and post self-efficacy tests. In addition, qualitative data was collected from feedback surveys, online postings, a research journal, and individual interviews.
The teachers demonstrated greater levels of self-efficacy with regard to the implementation of personal learning after their participation in the professional development community. Teachers reported increased confidence with regard to personal learning in the areas of planning, risk-taking, implementation, making modifications for continuous improvement, and sharing their knowledge with others. The teachers also reported learning about themselves, their students and colleagues, as well as gaining knowledge of content related to teaching, and personal learning. Participants reported the development of a variety of skills including design and problem-solving skills, technology skills, and facilitation and PL strategies. They also reported changes in certain dispositions such as flexibility and open-mindedness. The community created value for both the individuals and the organization.

Description
This mixed methods study examined instructor introduction videos for use in online learning. This study intended to identify the influence of video production value on student perceptions of student-instructor intent, specifically in the areas of perceived student-instructor communication and student-instructor connection. This study also examined which production style most accurately aligns student perceptions with instructor intent as well as which video production style is preferred by students.
Using a set of production guidelines, an instructor produced two introduction videos; one of low production value, one of high production value. Student participants were surveyed on their perceptions of the instructor as featured in both videos. The instructor was interviewed using similar questions in order to identify instructor intent and compare instructor intent to student perceptions.
Analysis of data showed that there was no statistical difference between video production value in students’ perceived student-instructor connection or student-instructor communication when compared to the instructor’s intent in the same areas. Data analysis also showed that a high production value was more accurate in portraying instructor intent, however a low production value was preferred by students and portrayed the instructor more positively.

Description
Online discussion forums have become an integral part of education and are large repositories of valuable information. They facilitate exploratory learning by allowing users to review and respond to the work of others and approach learning in diverse ways. This research investigates the different comment semantic features and the effect they have on the quality of a post in a large-scale discussion forum. We survey the relevant literature and employ the key content quality identification features. We then construct comment semantics features and build several regression models to explore the value of comment semantics dynamics. The results reconfirm the usefulness of several essential quality predictors, including time, reputation, length, and editorship. We also found that comment semantics are valuable to shape the answer quality. Specifically, the diversity of comments significantly contributes to the answer quality. In addition, when searching for good quality answers, it is important to look for global semantics dynamics (diversity), rather than observe local differences (disputable content). Finally, the presence of comments shepherd the community to revise the posts by attracting attentions to the posts and eventually facilitate the editing process.

Description
Distance education has grown over the past several years due to the integration of technology and its advancements. The flexibility, convenience to the learner, and cost-effectiveness of online learning contributes to this rise in popularity (Boling et al., 2012). Consequently, U.S. colleges and universities are quickly establishing a vast array of distance learning programs and initiatives (Ernest et al., 2013; Jones & Wolf, 2010; Northcote et al., 2015). Communication in these colleges and universities among professors and students is vital, but it is especially critical in an online learning environment where social relationships are formed from the information conveyed by computer-mediated communication (Tu, 2000). Communicating immediacy between the instructor and student, facilitating reflection, and furthering discourse can build rapport while allowing the student to engage with the course content (Tu, 2000; Swan et al., 2008). Further, communication between the professor and the student enhances a sense of belonging, individuality, and intimacy in online learning environments (Boling et al, 2012). Online professors operate in a unique digital space where they provide guidance, instruction, and support to their online students without being in the same place and time. The purpose of this action research study was to explore the perceptions of undergraduate students regarding the strategies that can be used to improve the professor-student communication within the online educational setting. I explored this phenomenon using the theory of transactional distance and the social presence theory. This action research study involved the intervention of a Communication (COMM) Suite along with the participation of undergraduate students who have experienced online learning using both synchronous and asynchronous platforms. I collected data using a Likert scale survey accompanied by individual semi-structured interviews.

Description
Distributed self-assessments and reflections empower learners to take the lead on their knowledge gaining evaluation. Both provide essential elements for practice and self-regulation in learning settings. Nowadays, many sources for practice opportunities are made available to the learners, especially in the Computer Science (CS) and programming domain. They may choose to utilize these opportunities to self-assess their learning progress and practice their skill. My objective in this thesis is to understand to what extent self-assess process can impact novice programmers learning and what advanced learning technologies can I provide to enhance the learner’s outcome and the progress. In this dissertation, I conducted a series of studies to investigate learning analytics and students’ behaviors in working on self-assessments and reflection opportunities. To enable this objective, I designed a personalized learning platform named QuizIT that provides daily quizzes to support learners in the computer science domain. QuizIT adopts an Open Social Student Model (OSSM) that supports personalized learning and serves as a self-assessment system. It aims to ignite self-regulating behavior and engage students in the self-assessment and reflective procedure. I designed and integrated the personalized practice recommender to the platform to investigate the self-assessment process. I also evaluated the self-assessment behavioral trails as a predictor to the students’ performance. The statistical indicators suggested that the distributed reflections were associated with the learner's performance. I proceeded to address whether distributed reflections enable self-regulating behavior and lead to better learning in CS introductory courses. From the student interactions with the system, I found distinct behavioral patterns that showed early signs of the learners' performance trajectory. The utilization of the personalized recommender improved the student’s engagement and performance in the self-assessment procedure. When I focused on enhancing reflections impact during self-assessment sessions through weekly opportunities, the learners in the CS domain showed better self-regulating learning behavior when utilizing those opportunities. The weekly reflections provided by the learners were able to capture more reflective features than the daily opportunities. Overall, this dissertation demonstrates the effectiveness of the learning technologies, including adaptive recommender and reflection, to support novice programming learners and their self-assessing processes.

Description
Both fashion design and education are areas where new technologies can have a significant impact. This dissertation examines the potential of virtual reality (VR) for fashion design education and focused on the profound affordances that virtual reality offers - immersion and agency. Using a phenomenological approach, the study combined arts-based research, observational field notes, and in-depth interviews to ascertain the potential value of adding VR to the fashion curriculum. A small group of 14 fashion design students participated in the study, engaging in passive viewing and active creating activities. The students reported their impressions and shared their designs. Results indicate that the use of VR in fashion design education can lead to deeper engagement, increased creativity, and enhanced learning experiences. The study found that students who used VR technology in their design and theory courses reported feeling more engaged. The data also revealed that students found the VR environment to be a valuable tool for exploring design ideas, enhancing creativity, and increasing confidence in their work. These findings have important implications for both design educators and industry professionals. The study concludes with recommendations for integrating VR technology into fashion design education and suggestions for future research.

Description
Computer supported collaborative learning (CSCL) has made great inroads in classroom teaching marked by the use of tools and technologies to support and enhance collaborative learning. Computer mediated learning environments produce large amounts of data, capturing student interactions, which can be used to analyze students’ learning behaviors (Martinez-Maldonado et al., 2013a). The analysis of the process of collaboration is an active area of research in CSCL. Contributing towards this area, Meier et al. (2007) defined nine dimensions and gave a rating scheme to assess the quality of collaboration. This thesis aims to extract and examine frequent patterns of students’ interactions that characterize strong and weak groups across the above dimensions. To achieve this, an exploratory data mining technique, differential sequence mining, was employed using data from a collaborative concept mapping activity where collaboration amongst students was facilitated by an interactive tabletop. The results associate frequent patterns of collaborative concept mapping process with some of the dimensions assessing the quality of collaboration. The analysis of associating these patterns with the dimensions of collaboration is theoretically grounded, considering aspects of collaborative learning, concept mapping, communication, group cognition and information processing. The results are preliminary but still demonstrate the potential of associating frequent patterns of interactions with strong and weak groups across specific dimensions of collaboration, which is relevant for students, teachers, and researchers to monitor the process of collaborative learning. The frequent patterns for strong groups reflected conformance to the process of conversation for dimensions related to “communication” aspect of collaboration. In terms of the concept mapping sub-processes the frequent patterns for strong groups reflect the presentation phase of conversation with processes like talking, sharing individual maps while constructing the groups concept map followed by short utterances which represents the acceptance phase. For “joint information processing” aspect of collaboration, the frequent patterns for strong groups were marked by learners’ contributing more upon each other’s work. In terms of the concept mapping sub-processes the frequent patterns were marked by learners adding links to each other’s concepts or working with each other’s concepts, while revising the group concept map.

Description
Preservice teachers are faced with many challenges as they enter their first year of teaching. This is particularly true when dealing with future-ready skills, such as technology integration in K-12 classrooms, an area where many higher education or teaching faculty may not feel comfortable or fluent enough to support preservice teachers or to model in their own instruction.
This action research study aimed to understand how faculty develop Technological Pedagogical Content Knowledge (TPACK) in ways that will help them to enhance their instruction and model technology integration for preservice teachers. An online community was created that allowed teacher educators to interact synchronously or asynchronously to collaborate, learn, and practice new technological skills. This community served as a place for teacher educators to play with new technology and to share their ideas and practices with their peers—ideally to begin the process of developing the knowledge and fluency with technology that would allow them to better support teacher education students.
Both qualitative and quantitative data were used to explore faculty’s development of TPACK. A pre-survey, retrospective pre-survey, and post-survey were administered and analyzed. Also, interviews of participants and observations of the online community were used to collect qualitative data.
The results of the study showed an increase in participants’ confidence for selecting technologies to enhance their instruction after they participated in the online community. Also, the participants felt more confident using strategies that combine content, technologies, and teaching approaches in their classrooms or other learning environments.
In Chapter 5, a discussion of the findings was presented, in which several main implications are shared for researchers who might be engaged in similar work. Also, the lessons learned from this action research are explained, as well as the limitations experienced in this study.
