    The Design Cycle for Education (DC4E)
    (DELFI 2021, 2021) Scheffel, Maren; Schmitz, Marcel; van Hooijdonk, Judith; van Limbeek, Evelien; Kockelkoren, Chris; Joppe, Didi; Drachsler, Hendrik
    The need for more and better online and blended education has lately become even more apparent. Many educational institutions had to pivot to emergency remote teaching. While online learning in itself is nothing new, the scope, suddenness and speed of this shift certainly was. However, courses and modules created for face-to-face settings, cannot simply be turned into blended or fully online ones easily. Learning design models can provide guidelines and guidance. Often, however, they are not constructed in a comprehensive way and are mainly conceptual. We thus created a procedural design model enriched with templates, tools, information and design examples to specifically support and facilitate the (re)design of blended and online learning and teaching and to thus provide quality education: the Design Cycle for Education (DC4E).

    Enhancing Geographical Learning Through GeoVR: Immersive Exploration and Topographic Analysis Educational Application
    (Proceedings of DELFI 2024, 2024) Sabah, Sam; Tillmann, Alexander; Weiß, David; Drachsler, Hendrik
    GeoVR, a Virtual Reality immersive educational application, facilitates pedagogical approaches in geographical education, enabling students and educators to explore and analyze landscape features. This research examines the benefits of this educational environment, enabling students to seamlessly transition between macro and micro perspectives of terrain, facilitating a comprehensive understanding of surface structures. GeoVR aims to improve learning experiences, while simultaneously enhancing the user’s understanding of topographical features and spatial relationships through scalable observation and interactive analysis tools. The application notably extends the scope of actions available to learners and educators in fields such as geography, geology, environmental studies, urban planning, and education. The precision of the representation, the interactive capabilities, the infinitely adjustable scales and the contribution to a realistic and immersive learning environment for geoinformation and processes can lead to a better understanding of the systems under investigation. Despite potential challenges, GeoVR seeks to bridge the gap between virtual and physical environments, changing how people learn and explore landscapes digitally.

    Stakeholder attitudes towards digitalization in higher education institutions
    (DELFI 2019, 2019) Biedermann, Daniel; Kalbfell, Lea; Schneider, Jan; Drachsler, Hendrik
    We report the results of a group concept mapping study on the topic of digital transformation in German higher education. Students, teachers and administrative employees participated in the study where they first gathered statements which were then clustered and ranked according to importance and feasibility. The results show agreement between all groups that matters of culture and mentality remain the biggest factors for a successful digitalization of higher education. While we found agreement between groups on the importance of topics, those working at the institution are more pessimistic of cultural changes than students. The unification of service platforms and the development of validated didactical concepts for digital learning offerings are also seen as open challenges.

    Tabbi - A Tangible Interface for Educational Chatbots
    (DELFI 2020 – Die 18. Fachtagung Bildungstechnologien der Gesellschaft für Informatik e.V., 2020) Wollny, Sebastian; Schneider, Jan; Rittberger, Marc; Drachsler, Hendrik
    With the increasing popularity of Artificial Intelligence in educational research, chatbots seem to be a promising future technology that could help students with their daily problems. As part of Smart Learning Environments, they can be permanently accessible by natural language via a variety of interfaces. To investigate the property of "tangibility", we present TABBI, an interface for educational chatbots that allows students to interact with a physical robot. This robot interface will be used in future comparative studies to evaluate interaction possibilities with educational chatbots. In this paper, we describe the general idea and context of TABBI.

    Trusted Learning Analytics
    (Proceedings of DELFI Workshops 2019, 2019) Schneider, Oliver; Drachsler, Hendrik; Rensing, Christoph; Steuer Jan Hansen, Tim
    Der bisherige Umgang kommerzieller Dienste mit persönlichen Daten hat zu großem Miss-trauen gegenüber intensiver Datensammlung und -verwertern geführt. Dies behindert maß- geblich die Einführung von Learning Analytics, trotz der unbestritten möglichen Vorteile. Mit dem Ansatz Trusted Learning Analytics und dem gleichlautenden Innovationsforum verfolgen wir durch verschiedene Maßnahmen das Ziel, dieses Misstrauen zu reduzieren und die Verbreitung von Learning Anayltics an den Hochschulen durch modellhafte Schritte zu befördern.

    “What can I help you with today?” - Exploring Opportunities of Learner Modeling for Online Educational Portals
    (DELFI 2019, 2019) Wollny, Sebastian; Schneider, Jan; Rittberger, Marc; Drachsler, Hendrik
    Online educational Portals (OEPs) subsume a field of online repositories for a wide range of stakeholders. They are characterized by easily accessible structures that do not require visitor accounts. Most OEPs therefore provide content in one way to all visitors also known as “one size fits all” approach. With this study, we examine if Web Analytics data can be used to infer the modeling of learners for OEPs. This would be the basis for additional and more personalized ways of providing content to various stakeholders. In order to draw conclusions about opportunities and limitations of Web Analytics in this regard, the data structure of the Fachportal Pädagogik, as one of the largest educational OEPs in Germany, is compared with a common Learner Modeling Framework. The evaluation of the results finally leads to two major challenges that must be overcome in order to achieve personalized content and learning experiences on OEPs.
