THE TEACHING ACTIVITY AND THE GENERATION OF MATHEMATICAL LEARNING OPPORTUNITIES

We present a case study that has been developed to inform about the teaching activity of a secondary mathematics teacher in a whole group discussion and the mathematical learning opportunities generated for the students in this classroom context. For data of one lesson we determine the episodes that shape the whole group discussion. For each episode we then examine the effects of the observed actions on the type of learning that can be encouraged. Our research reveals significant relationships between the teaching activity of the teacher and the creation and potential exploitation of mathematical learning opportunities on the part of the students.
