Interaction, particularly learner-learner interaction, needs to be cultivated in online classes in order for students to have a satisfying learning experience. This study considered two graduate level online classes in an effort to determine: 1) is cognitive style related to the quantity of learner-learner interaction in online courses, 2) is there a relationship between learner characteristics and learner posting preferences in learner-learner interaction in online courses, 3) how do selected learners differ in their use of interaction elements during online discussion, and 4) how do selected learners perceive their experiences in online courses. Using the Student Demographic Questionnaire, the Group Embedded Figures Test, the Text Analysis Tool, and an Interview Protocol developed by the researcher, the study was conducted with a mixed method design. Learner-learner interaction was considered in terms of the students' contributions to the FirstClass discussion activities that were completed as part of the course requirements. This study found that: a) there is not a correlation between cognitive style and quantity of learner-learner interaction, b) some learner characteristics do influence learner posting preferences, c) interaction elements during online discussion do not indicate the content of discussion, but do somewhat indicate how the discussion is taking place, and d) students have opinions on how their experiences in online courses should impact online course design, particularly in terms of knowing the learner and communication. Knowing the learner was discussed in terms of time management, motivation, and differences among learners. Communication was discussed in terms of spontaneity, isolation, freedom, and accountability. Course design was discussed in terms of flexibility, organization, accountability, and technology. The results of this study have implications regarding online course design and recommendations for future research.

Interaction is a core element in the design of blended and distance learning environments. The importance of understanding these interactions and what might increase effectiveness of such interactions in education is paramount for meaningful learning. This dissertation consists of two qualitative case studies designed to provide a rich, descriptive look at interactions in a high school distance/blended-learning context in the home-study and technology-meditated seminary program of The Church of Jesus Christ of Latter-day Saints. In the study article, Moore's (1989) interaction framework was used as a lens for understanding the learner experience. Thematic narratives were used to highlight themes related to students' perceived learning gains from learner-content interaction and their hesitancy to engage in learner-learner and learner-instructor interactions if they had not met personally. In the second study, Garrison's (2007) Community of Inquiry framework was used to understand the impact that teacher decisions, other than the selection of content, had on the cognitive and social climate of the learning experience. This study describes how a teacher's facilitation of social interaction influences the course learning outcomes. The results highlight the teacher's role in providing the educational and social climate needed to foster learner interactions. This study noted that when the teachers gave learners the opportunity to interact in a live setting, it appeared to foster the relationships needed to interact online. The narratives also highlight how a teacher helped learners interact with one another around content online.
