Samenvatting
A number of tools exist that allow people to build knowledge models of
system's behaviour. These tools use different screens and visualisations
to work with. However, the additional support learners need to have for
a successful modelling event have not yet been analysed. This thesis
describes an experimental study, which was carried out at the Hong Kong
Polytechnic University. The study analyses model building activities of
learners using Homer. Homer is a tool for building qualitative models of
system's behaviour. The goal of the research project was to discover how
to support students in building qualitative models effectively. Different
kinds of support were given to subjects when they used Homer to build
qualitative models during the experiment. Problems and difficulties
subjects encountered while constructing these qualitative models have been
identified. These problems and difficulties have been analysed in order to
produce requirements for the construction of modelling tools that
effectively support students in performing such a task.
