AskMobi is a tool for adolescents to engage in social science inquiry about issues important to them. The system has two components: a cell-phone application for collecting data and a web-based system for creating studies, analyzing data, and presenting results in a public forum where they can be critiqued. The system scaffolds adolescents� learning experiences by taking them through basic social science methodology step-by-step, while allowing the users to investigate issues they choose.
