This is a short example, but I now have my first graders "record" a math story problem using Voki, and we embed those on our class wiki. These are a huge hit, as students love to see and hear Voki characters, plus the digital content is super exciting for them; they also pick up tech. skills using embed codes and our wiki. Also, the communication and collaboration that can occur online on the wiki also feeds and fuels the discussion. We've even used Voki to read our Mother's Day letters. Also, super exciting...plus, then, moms visit the wiki and comment on students' pages, etc. Digital content can move discussions and learning forward in all sorts of meaningful, motivating, and exciting ways, I think.
