Abstract
MiLexicon is an innovative handheld system that helps self-directed learners employ personal learning environments in their language learning. We conducted interviews with experienced language learners in order to investigate the resources they use to support their language learning across formal and informal settings. Our analysis of these interviews reveals a process of self-initiated personal and collaborative language inquiry and identifies ways technology can support this kind of learning. Here we describe miLexicon, a software prototype for Android phones, which we have developed to meet these requirements.
