I am for collaborative learning where students do collaborative tasks; it fosters their language development because learners interact with each other. I am always striving for my lessons to be interactive and communicative and try to talk only 15% of a lesson to focus on pair and group work.

As to cooperative learning techniques, my students are engaged in doing projects, they draw placards, present them in front of the class, though we don't have much of computer facilities at school, we do a lot of debates and discussions.

For example, the 11th graders were dicussing "Social Welfare". They were split into 3 groupings and represented three countries: Russia-UK-US. It's so interesting that I could see who knew vocabulary and could talk on this topic and who couldn't. Though they took control for the output but the teacher always can tell which group has achieved. The matter is how to grade them, if they all worked and contributed together and I know that I am to grade only 3 or 5 students per lesson. I am always asking myself: How do I fairly and collectively assess this group activity? That's challenging.

When it comes to summative assessment, how you grade your students if there's a certain limit?
