I would like to show you one of my class examples, where students demonstrated presentations as results of their own little researches, the topic for that activity is "Discoveries". But you'll be more surprised when you found out students used Target Language (Uzbek) only during this activity. Even if you are not able to understand them, you will see how encouraged and motivated each student is. By the way, they are on 32nd week (full course is 47 week).
