ab: Summary: This paper uses an analytical tool refereed to as the MAD
(Modelling Activity Diagram) framework adapted from Schoenfeld’s
parsing protocol coding scheme to address the issues of how to
introduce mathematical modelling to upper secondary students. The work
of three groups of students engaged in solving so called realistic
Fermi problems were analysed using this framework, and it was observed
that the processes involved in a typical mathematical modelling cycle
were richly represented in the groups’ solving processes. The
importance of the social interactions within the groups was noted, as
well as the extensive use of extramathematical knowledge used by the
students during the problem solving session.
