ab: Summary: Through writing, students express many of their processes and ways
of thinking. Since at high school level some of the activities are
carried out with the graphing calculator, we intend to investigate the
contribution of this resource to promote the mathematical writing in
the learning of continuous nonlinear models at 11th grade. Adopting a
qualitative methodology, we collected and analyzed the students’
writing productions. What they write when using the calculator gives
evidence about the information valued (when they sketch graphics
without any justification); about the strategies used (when they define
the viewing window and relate different menus on the graphing
calculator); and about the reasoning developed (when they justify the
information given by the calculator and the formulation of
generalizations and conjectures validation).
