Spanish tutor teaching spanish to foreigners

I am a librarian and teacher at the University of Buenos Aires. I have been teaching online Spanish to children, teenagers and adults for 7 years. I usually prefer to use the immersive method, through songs, videos and lectures on texts, resorting to grammar when I see the need in the student. Obviously, if a person starts learning Spanish from scratch the methodology is totally different, although I also include other activities so that it does not become tedious.
