We investigated how families experienced immersion as they collaboratively made sense of geologic time and geoscience processes during a place-based, learning-on-the-move (LOTM) experience mediated by a mobile augmented reality (MAR) app. Our team developed an MAR app, "Time Explorers," that focused on how rock-water interactions shaped…

Our research conducted two iterations of a mixed methods design-based research project with 87 youths, to improve learners' collaboration and knowledge-building by using collaboration scripts during learning-on-the-move within a mobile computing intervention. We investigated how the informal mobile augmented reality app influenced children's…

Two cases of context-sensitive mobile computing curricula for children are shown to develop analytical understandings of how science-related sense-making talk can be supported through physical and digital environment interaction, which supports play and learning through movement. Our work investigates how proximity-based computing mediates…

This paper advocates for place-based education to guide research and design for mobile computers used in outdoor informal environments (e.g., backyards, nature centers and parks). By bringing together research on place-based education with research on location awareness, we developed three design guidelines to support learners to develop robust…
