In today's Web 2.0 world, teachers are perpetually struggling with how to incorporate technology into the classroom effectively in order to meet the diverse literacy needs of 21st-century learners. Utilizing the National Council of Teachers of English (NCTE, 2008) Position Statement addressing these needs, the theoretical framework of Lankshear and Knobel (2006), and work by Cummins, Brown, and Sayers (2007) emphasizing the possibilities of technology in achieving literacy goals, a framework by which to assess the incorporation of technologies in classrooms as a means to build students' new literacies was created. Finally, as a specific example, the framework was applied to the use of wikis to illustrate the literacy learning potential of both wikis and other new technologies.
