Graphic calculator use in leeds schools: fragments of practice

Abstract This article reports on the distribution of the use of graphic calculators over the whole secondary school population in a Local Education Authority (LEA) in the United Kingdom. Quantitative and qualitative census data on the extent and nature of graphic calculator use have been obtained. A feature of this project is in the use of a teacher research team to gather data naturalistically. This work was designed to augment previous work in this area by providing census details for an entire LEA and by including reasons why graphic calculators are not used. The authors found that the key factors which contributed to use were: expertise within mathematics departments; regard for graphic calculators as learning aides from mathematics staff and as information and communication technology from senior staff; a ‘critical mass’ of older/higher attaining students. Key factors which inhibited use of graphic calculators were: lack of time to learn how to use the calculator and how to teach with it; concern over recent examination restrictions; perceptions of computers being a resource priority
