Students were tested on two types of item: symbolisation items, calling for an algebraic description of some cartesian graph; and interpretation items, calling for the extraction of information from some verbally contextualised graph. The findings illustrate that, under appropriate conditions, access to information technology can have an important influence both on the mathematical approaches employed by students and on their mathematical attainment. On the symbolisation items, use of graphic calculators was associated not only with markedly superior attainment by all students, but with greatly enhanced relative attainment on the part of female students.
