A Tool for Solving Geometric Problems Using Mediated Mathematical Discourse (for Teachers and Pupils)

The research deals with teaching strategies in geometry. A strategic mediating tool to resolve geometric problems was developed.Underpinning theories are: Piaget's theory (1960), Van Hiele (1959), Vygotsky's socio-cultural communication approach and Feuerstein's theory of mediated learning (1998).The research is based a combination of teaching strategies focused on significant mediation between the material and heterogeneous groups of learners. The innovation is in providing a holistic response to the needs of pupils and geometry teachers.Mixed methods research will examine the influence of this tool on high school pupils and their attitudes to mathematics in general and geometry in particular
