Screencasting could be very useful in a language class. I look forward to create lessons using this tool. When I need to explain a grammar point or vocabulary word explicitly I write up lessons using a word document; I include visuals and use language I know my students will understand.
A possible way of improving these lessons and notes is through the use of screencasts. It allows me to record an audio file as I explain a grammar point or use a specific word in context. It gives students the chance to listen to a lesson repeatedly; so it could be a great tool to support different learning styles.
On the other hand, it could also be a useful tool for students to use. They could create screencasts to show their understanding of a concept, or show the subtleties of language; or use language in a greater context. For example, a great cross-curricular activity for Math and Spanish could be to explain, in Spanish, how to use a Quipu
Altough screencasting does not allow interaction; it becomes a resource for students to use continuously and a tool for them to show their understanding.
