Article Citation - WoS: 1Citation - Scopus: 1Dealing With Divergent Feedback Trajectories in Video-Mediated, Transnational, and Collaborative Task Design Meetings(Elsevier Sci Ltd, 2025) Colak, Fulya; Balaman, UfukThis study investigates mutual pedagogical decision making among transnational groups of preservice teachers (from Austria and T & uuml;rkiye) involved in finalizing the design of telecollaborative tasks after receiving multimodal feedback from different teacher educators. Within the scope of a Virtual Exchange project, while the teacher educator from the Turkish university conducted a large-group, whole-class, video-mediated meeting offering feedback, the teacher educator from the Austrian university preferred delivering written feedback. Examining the screen-recordings of pre-service teachers' video-mediated meetings and the diverse feedback sources, we found that the divergent feedback trajectories provide opportunities for pedagogical design-related decision making and meaning negotiation for pre-service teachers. The findings also show the synergies between the multilayered frameworks of participation and engagement in situ and bring new insights into the interactional management of video-mediated learning environments.Article Citation - WoS: 10Citation - Scopus: 10Observer-Based Adaptive Output Feedback Tracking Control of Dynamically Positioned Surface Vessels(Springer Verlag, 2017) Bıdıklı, Barış; Tatlıcıoğlu, Enver; Zergeroğlu, ErkanIn this work, we propose an observer-based adaptive output feedback tracking controller for dynamically positioned surface vessels. Specifically, to remove the velocity measurement dependency of the control formulation a nonlinear, model-free observer formulation have been proposed. The proposed observer does not make use of the system dynamics and together with the proposed controller structure ensure that the tracking error signal and the velocity estimation error asymptotically converges to zero. Stability of the closed-loop system is ensured by Lyapunov-based arguments. Simulation studies are also presented to illustrate the effectiveness of the proposed method.
