A simple technique for language LEARNING (not STUDYING) I used with my son at home in Japan (he speaks mostly Japanese) was to repeat back to him in English everything he says to me in Japanese (‘Onaka ga suita’, ‘Oh, you’re hungry now?’). He’s four now, and demonstrates comprehension in most things I say to him (though his Japanese ability has already surpassed mine....).
This technique is easy to apply in the classroom, too. If you want to make yours an 'English Only' classroom, give it a try!
