                                                    Abstract

   Professional noticing allows teachers to recognise important events in a classroom and
   give effective responses using their knowledge. Hence developing this competence in
   teacher training programs is an issue in the Mathematics Education field. In this study, we
   present the design of a learning environment about the part-whole meaning of fraction to
   develop pre-service primary school teachers’ noticing of students’ mathematical thinking.
   The learning environment is designed around three tasks (vignettes) that pre-service
   teachers have to analyse using knowledge from research on mathematics education
   provided as a students’ hypothetical learning trajectory. Eighty-five pre-service primary
   school teachers participated in this learning environment. Pre-service teachers’ written
   answers to the three tasks are the data of this study. Results allow us to characterise the
   enhancement of pre-service teacher noticing through looking at the changes in the
   discourse generated in the three tasks.

   Keywords: fraction; hypothetical learning trajectory; pre-service teacher; representations of
                  practice; teacher noticing.
