ab: Summary: The authors comment a phenomenon that is observed when analyzing
the teacher’s discourse while explaining the graphical representation
of functions in high school. The teacher uses expressions that suggest,
among others, metaphors like “The graph of a function can be
considered as the trace of a point that moves over the graph". In the
first part, the theoretical framework about the embodiment of mind
proposed by Lakoff and Núñez is presented. In the second part, the
authors comment the different metaphors that have structured the
concept of graph of functions. In the third part the study of a teacher
‒ following the sequence: a) video-recording of a class, b)
interviews, c) analysis of the productions of the students ‒ is
described which shows that the teacher uses these metaphors in a not
complete conscious way and that he believes that their effects in the
understanding of the students are innocuous. The authors end up with
some conclusions about the possible causes of this phenomenon.
