Current Projects

  • Advise-Me: The objective of this project is to develop flexible support for detailed diagnostics of mathematical competences of pupils, and to
    use this in digital environments of mathematics education. This results in dashboards for teachers to identify and help underachievers and to monitor groups (“Pilot-in-the-cockpit approach”) or awareness tools for pupils for an accurate understanding of their own performance and progress (“Fly-yourself-approach”). Also the system itself can use the diagnostic information for adapting the environment to the level of an individual, for example by selecting the next task to offer (“Autopilot-approach”). Please see for more information on the project’s website.
  • Adaptive argumentation support in Facebook. Building on former projects below, we develop a Facebook app that analyzes one’s personality type and provides tailored script support for building sound arguments on Facebook.
  • Argumentation diagrams on tabletops for supporting AppInventor designs. Here, groups of students jointly create a smartphone app with the help of a generic tabletop environment including collaboration scripts and awareness tools. The learning activities are orchestrated so that learners first jointly create and lay out the design on the tabletop and then use AppInventor to actually create the app.
  • Competence-Sea: Massive Open Online Courses (MOOCs) can foster equal access to education in specific regions. This project aims to empower specific groups of learners in Southeast Asia, such as single mothers in Malaysia, entrepeneurs in Indonesia, and rural health workers in the Phillipines with MOOCs.

Completed Projects

  • Arguing in Facebook – Pilot Project: Social networking sites (SNS), such as Facebook have the potential to host and support argumentative knowledge construction (AKC). However, little is known about how to use SNS for AKC. In this pilot project, we investigate the potential benefits of graphically represented computer-supported argumentation scripts. A follow-up field study using Facebook explores how an academic debate continues to impact learners’ voluntary Facebook use.
  • MUPEMURE STELLAR Theme Team: The MUPEMURE Theme Team investigates how learners can be facilitated to actively share, process and acquire multiple perspectives on multiple representations of mathematical and science topics. We combine latest technology for creating, modifying, and sharing representations in CSCL scenarios with group awareness and scripting approaches.
  • MuSuCoL STELLAR Theme Team: A significant paradigm shift is underway from traditional desktop computing of mouse and keyboard to interactive surfaces. The MuSuCoL Theme Team has two goals: (1) to better support and connect the research community around learning with interactive surfaces and (2) to advance the research on collaborative learning using multiple interactive surfaces.
  • Orchestrating AKC in SNS: In this project the benefits of supporting Argumentative Knowledge Construction (AKC) through Social Networking Sites (SNS), e.g. Facebook, are tested in combination with supporting awareness. A set of lab studies will investigate how computer-supported collaboration scripts may improve student AKC in SNS by (1) suggesting different sequences of argumentative moves and by (2) modifying students’ awareness to selected group features and their expectancy to engage in transactive debate with others.
  • Proportion (link leading to call for participation in German): The ipad-app „Proportion“ allows two kids to learn relations and proportions together. Tasks are becoming increasingly difficult and require different strategies to accomplish. Immediate feedback after each task and graphical tools facilitate kids’ understanding and application of the strategies.
  • Technology-Enhanced Collaborative Drawing: When learners draw their own representations of scientific phenomena (like photosynthesis) themselves they are stimulated to identify and link key concepts and processes. Drawing also has the potential to serve collaborative learning. In this project, 5th grade elementary school students worked collaboratively with a computer based drawing tool. A first inspection of the data revealed knowledge gains for all participating students.
