1- I always use authentic material;
2- I choose the audio according to the student's interest, or even ask them to choose what we'll listen to;
3- We take time to analyze it and listen way more than 3 times. One audio is usually studied for 2 or 3 lessons;
4- I encourage them to use vocabulary / structures learned from the audios in future moments.
I believe today I work on listening way better, but there's still a lot to learn and test. Let's go for it!
