ab: Summary: We assessed students’ modelling competency using a test
consisting of different classes of items. Within the first class there
are items which cover the whole modelling process, whereas items of the
second class focus only on certain parts of this process. To cope with
the requirements of the two different classes of items we used a
multidimensional Rasch model including subdimensions. In this chapter
we describe the structure of the test instrument and compare the
subdimensional scaling of the test results with a unidimensional one.
The analyses show the superiority of the subdimensional scaling.
