ab: Summary: Modelling competency is considered to be an important part of
mathematical competency. Although much work has been done with respect
to the development and dissemination of modelling tasks, there is
hardly any empirical evidence how these tasks should be integrated in
the mathematics classroom. In this article we present a teaching
approach based on heuristic worked examples which turned out to be a
promising way of supporting initial skill acquisition within the field
of modelling. We will provide an overview how the learning environment
(KOMMA) was conceptualized and will present first results of a
large-scale field study examining the effectiveness of example based
learning for initial skill acquisition in the field of modelling. The
results presented here take into account short-term as well as
long-term effects on the learning of 8th-grade students. They suggest,
that the participants’ modelling competencies increased significantly
during the training but that long-term effects were much smaller.
