Duolingo, the free language-learning app and website that I’ve posted about numerous times, and which a big favorite of my students and others around the world, is unveiling Duolingo For Schools next week (thanks to Richard Byrne for the tip).

It’s unclear exactly how it will work (it opens on January 8th), but it will let teachers create virtual classrooms and track student progress.

It’s their latest expansion — they also started a very low-cost language certification program last summer to rival the TOEFL. And they’ve announced plans to create an app to help people learn “basic literacy.” It’s amazing what they’ve accomplished in so short a time.

I’m adding this post to The Best Sites That Students Can Use Independently And Let Teachers Check On Progress.
