This article charts the development of three literacy research frameworks: multiliteracies, new literacies, and popular literacies. By reviewing the literature surrounding three current conceptions of literacy, an attempt is made to form an integrative grouping that captures the most relevant elements of each for learning environments design. Rather than showcasing the merits and weaknesses of each perspective (resulting in theoretical "winners and losers"), the frameworks are used to derive a core set of principles which might inform the design of interventions and artifacts to promote learning within informal learning environments for youth. These principles include exploring lifeworlds, recognising sources of power, multimodality, intertextuality, play and popular culture, design and production, and changing roles for adults.
