teachers' use of graphical representations
Summary: InterMath participants spend time in workshops exploring technologyrich mathematical investigations and completing writeups. These writeups 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 writeups that included incorrect mathematics and/or incorrect solutions. Our findings indicate that a large number of incorrect writeups included a graphical representation for cosmetic purposes, meaning that it was not used to explain or justify participants' solutions.
