For over fifteen years, I have been doing research in the field of the learning sciences and educational technology. My focus is on learning and instructional design. I do empirical research on socio-cognitive processes of learning, work on modelling instructional designs, and develop educational models for digital learning. My expertise also includes moderating the communication between different stakeholders of digital learning that do not always share the same ideas, backgrounds and vocabularies. My goal is to build educational models that flexibly take into account the needs but also the competencies of them.

I understand learning as the most important human characteristic. I am fascinated by the idea of socio-cognitive models of learning that may encompas the complexity of human learning. I am convinced that technology may help us derive such models, support and transform learning processes in formal education and informal learning settings. I am dedicated to overcoming potential pitfalls for progress (e.g. quality losses and confirmation biases) and to leveraging dynamic individual and group processes (e.g. argumentation, socio-cognitive conflict, embodied / narrative-based learning) as posibilities for learning.

In the past, I concentrated on intelligent tutoring systems and on how artificial intelligent techniques can be used to promote learning. I modelled schema theory of learning for hinting. I developed a model of proactive hints for natural language dialogue systems to foster active learning. I have also modelled and investigated learning through online erroneous examples to create learning opportunities through common errros in mathematics. In the field of chemistry, I applied adaptive collaboration scripts to explorative learning with a virtual chemistry lab.
