ab: Summary: This case is part of a teaching experiment that sought to provide
insight into how the use of mathematics technology affects the internal
mathematical representations possessed by adult developmental
mathematics students. Sequences of dot patterns were examined and
analyzed by the participant. He then used the algebraic features of a
dynamic, interactive geometry software program to graph data describing
the functional relationships present in those patterns. Insights about
the effect of technological representations on adult students’
thinking can be gained from observations of the subject’s
investigations of that data. Results show that appropriate use of
technology can aid adult students in building an understanding of
standard representations that is based upon their own thinking and
their own choices.
