Filling in the Gaps: Modelling Incomplete CBL Data Using a Graphing Calculator.
Swingle, David A.; Pachnowski, Lynne M.
International Journal of Mathematical Education in Science and Technology, v34 n3 p361-70 May-Jun 2003
Discusses a real-world problem-solving lesson that emerged when a high school math teacher used a motion detector with a CBL and graphing calculator to obtain the bounce data of a ping-pong ball. Describes the lesson in which students collect bad data then fill in the missing parabolas that result using critical components of parabolas and matrices. (Author/NB)
