I am the keynote speaker for Columbus City Schools’ District-wide Professional Development Day, 9 December 2009, at the Columbus Global Academy. The PD strand title is ‘Strategies to Improve Literacy for ESL Students’. My talk ‘Expanding Repertoires’ draws upon my own research in multilingual communities, research on language learner beliefs and (language) learning strategies, and recent meta-studies of research on literacy development among language-minority children and youth.
