Gamification of learning is the best way to teach, for children and adults alike.
Imagina a new app that teaches foreign languages from a hand-picked pool of cool songs which you can listen to, see the lyrics, the translation line by line. Last but not least, the ability to sing karaoke would be the killer feature, allowing social interactions inside and outside the app on social media.
That would be a fun experience and a great way to teach a foreign language.
