Theory-based support for mobile language learning: noticing and recording
This paper considers the issue of 'noticing' in second language acquisition, and argues for the potential of handheld devices to: (i) support language learners in noticing and recording noticed features 'on the spot', to help them develop their second language system; (ii) help language teachers better understand the specific difficulties of individuals or those from a particular language background; and (iii) facilitate data collection by applied linguistics researchers, which can be fed back i
Rural Voices Winding through the Andes Mountains: A Collective Creative Literacy Research Project
This dissertation was a collective creative literacy research study
of a rural community in the Western part of the Venezuelan Andes. First, this
study aimed at portraying the meanings attached to some forms of “vernacular
literacy” (Barton and Hamilton, 1998) embedded in people’s everyday lives in
