ab: Summary: We report the use of a tool to display and analyze essential
elements of mathematical activity (definitions, properties, processes,
etc.) arising during the development of a class. It has been applied to
the study of the commonalities and differences among three classes
conducted by three different teachers in the same institution, year and
school level when they teach the bisector. The results allow us to
infer some aspects about the mathematical knowledge of the teachers
involved.
