Abstract(s)
The curricular changes that have occurred with the Portuguese Mathematics programme
of study of 2007 showed, among other situations, the introduction of new contents and
the new concept of symmetry. For the teachers, these changes require scientific updates
to be provided so that the outcomes of the mathematics teaching can be guaranteed. In
the academic year 2011/2012 a questionnaire was applied to a 142 inservice basic
education teachers of a particular region of Portugal, to analyze the content knowledge
in this subject (symmetry) and the form of scientific update occurred. The processing of
data allowed us to identify inadequate conceptions, beliefs, topics more or less
successful in responses and also compare the teacher’s responses of the different
teaching groups.
