    Beyond words: investigating non-verbal indicators of collaborative engagement in a virtual synchronous CSCL environment
    (Frontiers Research Foundation, 14.08.2024) Jeitziner, Loris Tizian; Paneth, Lisa; Rack, Oliver; Zahn, Carmen [in: Frontiers in Psychology]
    In the future of higher education, student learning will become more virtual and group-oriented, and this new reality of academic learning comes with challenges. Positive social interactions in virtual synchronous student learning groups are not self-evident but need extra support. To successfully support positive social interactions, the underlying group processes, such as collaborative group engagement, need to be understood in detail, and the important question arises: How can collaborative group engagement be assessed in virtual group learning settings? A promising methodological approach is the observation of students’ non-verbal behavior, for example, in videoconferences. In an exploratory field study, we observed the non-verbal behavior of psychology students in small virtual synchronous learning groups solving a complex problem via videoconferencing. The groups were videorecorded to analyze possible relations between their non-verbal behaviors and to rate the quality of collaborative group engagement

    A multi-method approach to capture quality of collaborative group engagement
    (International Society of the Learning Sciences, 2023) Paneth, Lisa; Jeitziner, Loris Tizian; Rack, Oliver; Zahn, Carmen; Damsa, Crina; Borge, Marcela; Koh, Elizabeth; Worsley, Marcelo [in: Proceedings of the 16th International Conference on Computer-Supported Collaborative Learning - CSCL 2023]
    Multi-method approaches are an emerging trend in CSCL research as they allow to paint a more comprehensive picture of complex group learning processes than using a single method. In this contribution, we combined measures from different data sources to capture the quality of collaborative group engagement (QCGE) in CSCL-groups: QCGE-self-assessments, QCGE-ratings of verbal group communication, and video recorded nonverbal group behaviors. Using different methods of analysis, we visualized, described, and analyzed the data and related the measures to each other. Here, we present results suggesting that measures from different data sources are interrelated: For instance, nonverbal behavior (like nodding the head) is related to high QCGE-ratings of verbal communications. Results are preliminary and show disparities, too. Yet, we conclude that the multi-method approach results in a more comprehensive understanding of QCGE. Feasibility and suitability of the multi-method approach are discussed and conclusions for future research are drawn.

    Exploring nonverbal behavior and collaborative group engagement in online learning groups
    (22.07.2022) Rack, Oliver; Paneth, Lisa; Jeitziner, Loris Tizian; Zahn, Carmen
    In an explorative field study, we investigated nonverbal behavior and collaborative group engagement (QCGE) in online learning groups. Participants in small groups performed a hidden profile task. Results suggests differences within and between groups in their nonverbal behavior. We expect that nonverbal behaviors relate to QCGE in online learning groups.
