Projects with classEx

classEx is the core software for some related projects in different fields.

Lioness Lab

Together with Dr. Lucas Molleman and Prof. Dr. Simon Gächter from the University of Nottingham we are building a development tool for experiments in online labour markets like Amazon MTurk. This tool is based on a similar logic as classEx but takes into account the special needs when running experiments online.

Experiments for Teaching in Schools

Together with the Joachim Herz Foundation we implement experiments for Highschool teaching in Germany.  More information (in German) can be found here.

Experimental Repository

In cooperation with the GESIS – Leibniz Institute for the Social Sciences in Cologne we participate as cooperation partners at a DFG project called x-econ to build up a respository for experimental data. More information on the project can be found at
