Sparking interest: A design framework for mobile technologies to promote children's interest in nature

Can a mobile app engage children in explorations of the natural world and promote their interest in nature? Drawing on theory related to interest development and research on mobile learning technologies, we derived a set of four design principles to support the development of children's personal interest in nature. We co-designed with 7 children ages 7-12 a set of interest-centered design strategies to implement each of the following principles: (1) personal relevance, (2) focused attention, (3) social interactions, and (4) opportunities for continued engagement. We applied these strategies to design NatureCollections, a mobile application that allows children to build, curate, and share nature photo collections. We conducted an in-situ case study with 18 children ages 7-11 years who used the NatureCollections app to take pictures of their natural surroundings. Qualitative indicators suggest NatureCollections succeeded in directing children's attention to and promoting close observation of the natural elements in their surroundings, and prompted playful, nature-related conversations with peers and parents.
