Pocket PiCoMap

Abstract

Our project explores the benefits and challenges of using handheld computers to support learners in creating concept maps (a type of visual outline). By synthesizing research on small user interfaces with guidelines for building desktop learning tools, we identified potential challenges to using handhelds for complex learning tasks and developed new design guidelines to address these issues. We applied these guidelines to the design of Pocket PiCoMap, a learner-centered concept mapping tool for handheld Pocket PCs. As part of a 9-month classroom study, students used both the handheld Pocket PiCoMap and a comparable desktop concept mapping tool called PiViT. The goal of this comparison between handheld and desktop tools was to better understand how the different form factors of these computers impact students' work processes and products. Our results suggest that students can successfully complete complex learning activities using handheld tools, and that specialized supports (called scaffolds) can be used to help students create better concept maps. This study also identifies several areas where handheld learning tools need further improvements, such as helping students organize their work within the confines of small handheld screens, and we discuss ways in which scaffolds might be used to improve future handheld learning tools.
