Graphing investigations using portable (palmtop) technology

The increasing use of portable computers raises issues about their impact on learning and attitudes to computing. These issues were explored in an evaluation of a weather project undertaken by 48 students aged 13–14 using palmtop computers. Students worked in groups over 3 weeks, collecting and graphing temperature data. Motivation and confidence in using technology increased and learning gains of averages and graph interpretation were observed. The evaluation illustrated the potential power and versatility of portable technology in tackling graphing, and the opportunities they present for student participation. Some pedagogic implications of using portables are considered.
