The PIGMI (Portable Information Technologies for supporting Graphical Mathematics
Investigations) Project investigated the role of portable technologies in facilitating
development of students' graphing skills and concepts. This paper examines the impact
of a recent shift towards calculating and computing tools as increasingly accessible,
everyday technologies on the nature of learning in a traditionally difficult curriculum
area. The paper focuses on the use of graphic calculators by undergraduates taking
an innovative new mathematics course at the Open University. A questionnaire survey
of both students and tutors was employed to investigate perceptions of the graphic
calculator and the features which facilitate graphing and linking between representations.
Key features included visualization of functions, immediate feedback and rapid graph
plotting. A follow-up observational case study of a pair of students illustrated how
the calculator can shape mathematical activity, serving a catalytic, facilitating
and checking role. The features of technology-based activities which can structure
and support collaborative problem solving were also examined. In sum, the graphic
calculator technology acted as a critical mediator in both the students' collaboration
and in their problem solving. The pedagogic implications of using portables are considered,
including the tension between using and over-using portables to support mathematical
activity. |
