Description
Honors programs in the United States offer high-quality educational experiences for exceptional students at the undergraduate level. These experiences generally take place in a face-to-face format. In recent years, higher education embraced online learning as a strategy to increase flexibility and access for students with diverse needs. Research has clearly established online learning as an effective model for high-quality education, yet, honors programs have been resistant to this shift in learning modalities. The community of inquiry theoretical framework provided a method for the assessment of online discussions and courses using a validated survey and coding instrument. Using a critical digital pedagogical lens to guide this mixed-methods participatory action research (PAR) study, an online honors seminar course was implemented in the fall of 2021. Honors students worked alongside the researcher as they developed an assessment tool based on the community of inquiry survey, selected different online discussion tools, and provided ongoing feedback throughout the course. Two research questions guided the study. First, what were student perceptions of different online discussion tools and their utility in facilitating social and cognitive presence in an online honors seminar course? And, second, how did engaging in a critical PAR research study impact an honors student’s experience in an online honors seminar course? Data were collected from students’ open-ended reflections, transcripts of online discussions, and responses to the revised community of inquiry survey.
The results from this PAR study showed that students spoke favorably about all online discussion tools implemented in the online honors seminar course and each discussion tool was found to be effective in nurturing social and cognitive presence. Students also spoke favorably about their experiences engaging in the PAR study. The most important finding was that by authentically engaging students in the design, implementation, and assessment of an online honors seminar course high-quality learning outcomes could be achieved in an online environment. Within the honors community, future research and practice regarding the intersection of honors curriculum and online learning are essential to maintain the relevancy of honors programs.

Description
With advances in automatic speech recognition, spoken dialogue systems are assuming increasingly social roles. There is a growing need for these systems to be socially responsive, capable of building rapport with users. In human-human interactions, rapport is critical to patient-doctor communication, conflict resolution, educational interactions, and social engagement. Rapport between people promotes successful collaboration, motivation, and task success. Dialogue systems which can build rapport with their user may produce similar effects, personalizing interactions to create better outcomes.
This dissertation focuses on how dialogue systems can build rapport utilizing acoustic-prosodic entrainment. Acoustic-prosodic entrainment occurs when individuals adapt their acoustic-prosodic features of speech, such as tone of voice or loudness, to one another over the course of a conversation. Correlated with liking and task success, a dialogue system which entrains may enhance rapport. Entrainment, however, is very challenging to model. People entrain on different features in many ways and how to design entrainment to build rapport is unclear. The first goal of this dissertation is to explore how acoustic-prosodic entrainment can be modeled to build rapport.
Towards this goal, this work presents a series of studies comparing, evaluating, and iterating on the design of entrainment, motivated and informed by human-human dialogue. These models of entrainment are implemented in the dialogue system of a robotic learning companion. Learning companions are educational agents that engage students socially to increase motivation and facilitate learning. As a learning companion’s ability to be socially responsive increases, so do vital learning outcomes. A second goal of this dissertation is to explore the effects of entrainment on concrete outcomes such as learning in interactions with robotic learning companions.
This dissertation results in contributions both technical and theoretical. Technical contributions include a robust and modular dialogue system capable of producing prosodic entrainment and other socially-responsive behavior. One of the first systems of its kind, the results demonstrate that an entraining, social learning companion can positively build rapport and increase learning. This dissertation provides support for exploring phenomena like entrainment to enhance factors such as rapport and learning and provides a platform with which to explore these phenomena in future work.
