 Hi Karen, my name is Miguel Brekner. I run the program Seibali in Uruguay. It's the program by which we've given a laptop to every child and every school teacher and every teacher in the country. You were talking about personalization and talking about the infrastructure. Do you have any plans on getting to every student with either a laptop or a tablet or being able to work together so that the teacher knows what's happening with him and he can get directly access to all the digital information? Absolutely. So first of all, I want to absolutely congratulate you. I was actually talking with the Secretary of Education last weekend, Arne Duncan, and telling him about your country, about what South Korea has announced by 2014. And he was incredibly interested in what you have done. You really have been, you are stepping out as a leader across the world. So first of all, thank you very much. I think you're showing kind of what's possible and you're powering up learning for every single student. So we're very interested and we're also interested in what you're finding, what the practice is, how long it takes to actually transition. In the United States, we have kind of like 50 little countries when it comes to education. So there are states that are looking at saying by 2014 or whatever, we will in fact be like Uruguay and provide every laptop. So we definitely are very interested in following your work and many people in the country are also saying, hey, we should be leaders. We should lead this. We should also lead this effort. So as we go, we definitely want to learn from you and follow in your footsteps. The personalization part of it is not a given. As I travel and visit classrooms where all students have devices of any kind, many classrooms are still in lockstep. Having every student do the same thing at the same time, stay on the same screen. It's a habit and a practice that's going to be incredibly hard to break. I think one of the things that we need are better products. We need better content, better interactive environments, better interfaces that guide the learner and take them where they are. Rather than in the previous question, rather than thinking about the learner as a consumer and providing them the information to consume. One last thing I'll say, one of the things that we're really interested in, an online website where people can work together on this, but creating more and more compelling assignments for students. Not fluffy projects, not cute assignments, but really come deep assignments that engage them, that get students working together. That's very participatory, that allows them to access experts, that allows them to think deeply about things and bring their particular kind of angle or expertise to potentially solve complex problems. So this notion of creating more compelling assignments, that is something that I think we can engage all educators in doing. So that they aren't kind of snapping back to what's comfortable and that is controlling and managing and making sure that every student is kind of staying with them. So again, thank you for the leadership that you're showing across the world. Thank you very much.
