Recently, I participated in a roundtable discussion through TCU on the topic of dynamic assessment and translanguaging. My topic was dynamic assessment. But, I was really struck by the notion of translanguaging.
It was an interesting discussion about how to provide support to children in both languages and allow them to have access to both of their languages to maximize opportunities for language interaction. You might want to read more about translanguaging using the link above and also here. I think that translanguaging is a powerful way to support linguistic development and access in bilingual youth.
