My research focuses on the question how creativity, cognitive change, and learning can be stimulated by constructing diagrammatic representations, and by experimenting with those representations. This idea has first been developed by Charles S. Peirce in his concept of "diagrammatic reasoning."

Since 2004, I developed "Logical Argument Mapping (LAM)," a method and diagrammatic system of representation that is supposed to stimulate critical thinking. LAM has been implemented in the interactive and web-based software AGORA-net: Participate - Deliberate!

AGORA-net is on online world in which everyone can construct arguments or participate in debates. Its development is funded by the U.S. Department of Education.

Most recently I work on collaborative and problem-based learning environments for ethics and for science education in which AGORA-net is used as a tool to focus and guide autonomous collaboration among small groups of students.
