    • Zeitplan von Vorlesung, Präsenzübung und Tutorium File 71.9KB

      Zur Erläuterung:

      1.  Die Termine der Vorlesung (Vxx) sind Empfehlungen, zu denen die Vorlesungsvideos gesehen werden sollten, weil sie zum einen keine Überschneidungen mit anderen Veranstaltungen haben, zum anderen einen gewissen Vorlauf ermöglichen, um die Aufgaben der Präsenzübung in der Folgewoche vorzubereiten.
      2. Die Termine der Präsenzübung (Üxx) folgen ein oder mehreren Vorlesungsterminen. Sie sind - solange die Lehre digital gehalten werden muss - Zoom-Meetings, zu denen etwa 1/4 Stunde vor dem Meeting eingeladen wird. Bitte bereiten Sie die Übungen , die in den Vorlesungsfolien gestellt sind, so weit wie möglich vor. Nach der Präsenzübung werden jeweils auch Musterlösungen zu den Übungsaufgaben hochgeladen (Sciebo-Ordner "Handout-mit-Lösung")
      3. Die Termine des Tutoriums (Txx) sind ebenfalls Zoom-Meetings, zu denen  ebenfalls etwa 1/4 Stunde vorher eingeladen wird. Etwa 1 Woche vor dem Meeting erhalten Sie einen Übungszettel, den Sie an diesem Termin selber rechnen können. Das Meeting dient dazu, im Plenung oder in Breakout-Sesstions persönliche Fragen zu stellen. Die Aufgaben sollen hier nicht einfach vorgerechnet werden. Nach dem Meeting wird eine Musterlösung des Übungszettels hochgeladen. Sollten Sie zu dieser Lösung dann noch Fragen haben, so können diese im nachfolgenden Meeting ebenfalls gestellt werden.
      4. Es gibt einen Mattermost-Kanal für die Veranstaltung, der ebenfalls - bevorzugt zur Zeit des jeweiligen Meetings - für Fragen genutzt werden kann.

          Topic outline

          • General

            • The increasing ubiquity of collaborative, social networking, and mobile computing technologies is playing a key role in transforming work practices. Such technological affordances have influenced the communicative and collaborative practices that offer new opportunities but also challenges to contemporary organizational and inter-organizational systems. Yet our understanding of these changes and the implications for management remain poorly developed. Hence, this course attempts to offer rich theoretical and practical insights into the various dimensions of the relationship between communication and collaboration processes and technological advances in various organizational and inter-organizational contexts. In so doing, it will draw on bodies of social and organization theory to develop in-depth understanding of communication and collaboration practices that are at the heart of organizational and societal transformations in the Digital Age.

              Importantly, a key rationale of this course is to provide students with a mature and actionable understanding of this emerging landscape, with a view to shaping various collaborative arrangements and handling the related communication and technical challenges.

            +

            For part 1, each student must work through self-study presentations ahead of class meetings. During our meetings, we + discuss students' questions as well as review questions. In parallel to part 1, students work in groups to collaborate on answers to selected review questions in a Git repository.

            +

            The self-study presentations are maintained as Open Educational Resources in a public Git repository. Any form of communication and collaboration (feedback, suggestions, improvements) is very welcome!

            • Registration for Mattermost team Page

              Mattermost, a free and open in-browser chat system hosted by WWU IT (maybe an alternative to Slack), may provide more lightweight means of communication than Learnweb forums. Instructions are provided on this page.

          Topic outline

          • General

            • The increasing ubiquity of collaborative, social networking, and mobile computing technologies is playing a key role in transforming work practices. Such technological affordances have influenced the communicative and collaborative practices that offer new opportunities but also challenges to contemporary organizational and inter-organizational systems. Yet our understanding of these changes and the implications for management remain poorly developed. Hence, this course attempts to offer rich theoretical and practical insights into the various dimensions of the relationship between communication and collaboration processes and technological advances in various organizational and inter-organizational contexts. In so doing, it will draw on bodies of social and organization theory to develop in-depth understanding of communication and collaboration practices that are at the heart of organizational and societal transformations in the Digital Age.

              Importantly, a key rationale of this course is to provide students with a mature and actionable understanding of this emerging landscape, with a view to shaping various collaborative arrangements and handling the related communication and technical challenges.

            • Zeitplan von Vorlesung, Präsenzübung und Tutorium File 71.9KB

              Zur Erläuterung:

              1.  Die Termine der Vorlesung (Vxx) sind Empfehlungen, zu denen die Vorlesungsvideos gesehen werden sollten, weil sie zum einen keine Überschneidungen mit anderen Veranstaltungen haben, zum anderen einen gewissen Vorlauf ermöglichen, um die Aufgaben der Präsenzübung in der Folgewoche vorzubereiten.
              2. Die Termine der Präsenzübung (Üxx) folgen ein oder mehreren Vorlesungsterminen. Sie sind - solange die Lehre digital gehalten werden muss - Zoom-Meetings, zu denen etwa 1/4 Stunde vor dem Meeting eingeladen wird. Bitte bereiten Sie die Übungen , die in den Vorlesungsfolien gestellt sind, so weit wie möglich vor. Nach der Präsenzübung werden jeweils auch Musterlösungen zu den Übungsaufgaben hochgeladen (Sciebo-Ordner "Handout-mit-Lösung")
              3. Die Termine des Tutoriums (Txx) sind ebenfalls Zoom-Meetings, zu denen  ebenfalls etwa 1/4 Stunde vorher eingeladen wird. Etwa 1 Woche vor dem Meeting erhalten Sie einen Übungszettel, den Sie an diesem Termin selber rechnen können. Das Meeting dient dazu, im Plenung oder in Breakout-Sesstions persönliche Fragen zu stellen. Die Aufgaben sollen hier nicht einfach vorgerechnet werden. Nach dem Meeting wird eine Musterlösung des Übungszettels hochgeladen. Sollten Sie zu dieser Lösung dann noch Fragen haben, so können diese im nachfolgenden Meeting ebenfalls gestellt werden.
              4. Es gibt einen Mattermost-Kanal für die Veranstaltung, der ebenfalls - bevorzugt zur Zeit des jeweiligen Meetings - für Fragen genutzt werden kann.

                  Topic outline

                  • General

                    • The increasing ubiquity of collaborative, social networking, and mobile computing technologies is playing a key role in transforming work practices. Such technological affordances have influenced the communicative and collaborative practices that offer new opportunities but also challenges to contemporary organizational and inter-organizational systems. Yet our understanding of these changes and the implications for management remain poorly developed. Hence, this course attempts to offer rich theoretical and practical insights into the various dimensions of the relationship between communication and collaboration processes and technological advances in various organizational and inter-organizational contexts. In so doing, it will draw on bodies of social and organization theory to develop in-depth understanding of communication and collaboration practices that are at the heart of organizational and societal transformations in the Digital Age.

                      Importantly, a key rationale of this course is to provide students with a mature and actionable understanding of this emerging landscape, with a view to shaping various collaborative arrangements and handling the related communication and technical challenges.

                  Topic outline

                  • General

                    • The increasing ubiquity of collaborative, social networking, and mobile computing technologies is playing a key role in transforming work practices. Such technological affordances have influenced the communicative and collaborative practices that offer new opportunities but also challenges to contemporary organizational and inter-organizational systems. Yet our understanding of these changes and the implications for management remain poorly developed. Hence, this course attempts to offer rich theoretical and practical insights into the various dimensions of the relationship between communication and collaboration processes and technological advances in various organizational and inter-organizational contexts. In so doing, it will draw on bodies of social and organization theory to develop in-depth understanding of communication and collaboration practices that are at the heart of organizational and societal transformations in the Digital Age.

                      Importantly, a key rationale of this course is to provide students with a mature and actionable understanding of this emerging landscape, with a view to shaping various collaborative arrangements and handling the related communication and technical challenges.
