- KonferenzbeitragRestructuring Linear Discussions in Mind Maps by Crowdsourcing(DeLFI 2018 - Die 16. E-Learning Fachtagung Informatik, 2018) Elias, Julius; Dietze, Felix; Roepke, René; Schroeder, UlrikWith the rapid growth of the Internet, mobile computing and e-learning, more and more communication is happening online. With a large number of participants in e.g. MOOCs, discussions in linear structures can quickly become complex. Drawbacks of linear discussions motivate our approach to structure such discussions in mind maps. To control the restructuring process, we have created a series of user tasks that can be executed with the help of crowdsourcing. A two-stage study supported the conception and evaluation of suitable tasks. In addition, the study assesses the tasks’ potential for crowdsourcing and whether users need to know the entire discussion to process the tasks. The results indicate that all tasks are suitable for a crowdsourced approach.
- KonferenzbeitragWebWriter: A System to Author and Remix Explorables – Requirements & First Prototype(Workshops der 21. Fachtagung Bildungstechnologien (DELFI), 2023) Salmen, Frederic; Roepke, René; Schroeder, UlrikActive and personalized learning requires that teachers can remix a wide variety of sources into new learning resources, which in turn may be customized by students. While this is well-supported for paper-oriented resources, multimodal, interactive learning resources for digital use, called explorables, are much more difficult to author and remix. In this paper, we derive a set of requirements for a system to author such explorables from a workshop-based study. We further present a first prototype of such a system, called “WebWriter”.
