ab: Summary: In a quasi-experimental study that was carried out in the
framework of MultiMa-project, we compared two groups of 9th graders
from six middle track classes. In one group modelling tasks, where the
solutions do not demand making assumptions about the missing data, were
treated for five lessons. In the other group students solved similar
modelling problems, where different assumptions were possible and
students had to develop two and more different solutions five lessons
long. Before and after the teaching unit students answered
questionnaires about planning and monitoring their activities while
solving problems. The analysis showed the positive influence of
treating and developing multiple solutions on students’ planning and
monitoring activities.
