Review article 38 Tanner, Howard. 1992. Developing the use of IT within mathematics through action research. Computers and Education, 18 (1-3), 143-148. This article assesses the extent to which IT skills are used or developed within mathematics in Britain and examines factors, which are limiting development. The results of an action research project, which investigated the extent to which IT skills could be taught within the mathematics curriculum, are described. The findings of the study can be summarized as follows– generic computer software can be used to enhance the teaching of mathematics; IT skills relating to the use of generic computer software can be taught effectively in the context of lessons, primarily mathematical; the majority of mathematics teachers need training in the use of generic packages; the training required is not simply technical but also how to use computers to support subject learning; beginners with computer software often need support in the classroom in the early stages; lack of access to computers is a problem for many mathematics teachers; and the integration of computer based lessons into schemes of work facilitates forward planning and thus access to hardware. The author further argues that the shift of emphasis away from IT as a separate subject and towards integration into the curriculum as a whole is educationally sound. However, he maintains that to achieve this, a large scale programme of in-service training is required.
