(from Conclusions paragraph:)
The students, largely, are not conscious of their own conceptions and consequently do not begin to question them. The preliminary results of the study indicates that students have incorporated the "new" quantum phenomena into "older" mechanistic conceptions. Further work will need to be done, but the current data implies that most students are not epistemologically aware that quantum physics constitutes a new "paradigm".
The preliminary results are generally consistent with previous research in other countries. However, further work needs to be carried out using a larger database to establish the generalizability of any findings, and more focused research on the use of figurative language (e.g. metaphors and analogies) and the interrelationships between conceptions.
