ab: Summary: InterMath participants spend time in workshops exploring
technology-rich mathematical investigations and completing write-ups.
These write-ups include a written explanation of their problem solving
process, screen captures of files that they generated while completing
the investigation and links to these files. This paper examines the use
of graphical representations in write-ups that included incorrect
mathematics and/or incorrect solutions. Our findings indicate that a
large number of incorrect write-ups included a graphical representation
for cosmetic purposes, meaning that it was not used to explain or
justify participantsâ€™ solutions.
