National and international curriculum documents give emphasize on
geometric transformations. In particular, parameters of geometric
transformations play crucial role in defining geometric transformations. Thus, it
needs to be explored to what extent prospective teachers use parameters in explaining
geometric transformations. In this study, qualitative case study methodology
was used and participants were sixteen prospective middle school mathematics
teachers enrolled in a teacher education program in Turkey. To reveal
prospective teachers’ use of parameters in explaining geometric
transformations, a transformation geometry activity was designed and
implemented. During the implementation of activity, classroom observations were
carried out. The classroom observations focused on participants’ small group
discussions and whole class discussions surrounding geometric transformation
concepts. Moreover, implementation of the activity was audio-taped and
video-taped. Participants’ use of parameters was revealed by using written
materials and participants’ explanations during the whole class discussions. The
findings showed none of the pairs provided totally correct explanations for
geometric transformations. They had partial understanding about the parameters
of rotation. Even worse, one of the pairs held incorrect ideas about
identification of the angle of rotation.
