The potential of portable technologies for supporting graphing investigations

This article begins by reviewing the relevant research literature concerning the portable revolution in education. It outlines the advantages and disadvantages of portable forms of technology, with an emphasis on their potential impact upon student learning and attitudes. (The focus is on mathematics as far as possible, but writing is touched upon too as it is the main use for computers in school and hence the subject of much research.) A detailed discussion is then undertaken of the research on students’ understanding of graphing and studies with graphic calculators and portable computers. We also discuss the related trend towards investigative learning in mathematics, the use of ‘real world’ activities, issues concerning collaborative use of portable computers and research on relevant gender issues. The review concludes that portable graphing technologies present an important opportunity to help students develop understanding and skills in the traditionally difficult curriculum
