比尔·盖茨慈善演讲:关注非洲,改变世界

当说到自己的个人贡献时，比尔·盖茨说他最近去了一趟尼日利亚，正在与治愈那里死灰复燃的小儿麻痹症作斗争。他补充说，跟疾病作斗争是很有意义的事情，就像从事软件一样。"我是一个乐观的人，我认为任何问题都可以被解决的。"盖茨说。

When you actually go and sit in one of these classrooms, at first it's very bizarre. I sat down and I thought, "What is going on?" The teacher was running around, and the energy level was high. I thought, "I'm in the sports rally or something. What's going on?" And the teacher was constantly scanning to see which kids weren't paying attention, which kids were bored, and calling kids rapidly, putting things up on the board. It was a very dynamic environment, because particularly in those middle school years -- fifth through eighth grade -- keeping people engaged and setting the tone that everybody in the classroom needs to pay attention, nobody gets to make fun of it or have the position of the kid who doesn't want to be there. Everybody needs to be involved. And so KIPP is doing it.

How does that compare to a normal school? Well, in a normal school teachers aren't told how good they are. The data isn't gathered. In the teacher's contract, it will limit the number of times the principal can come into the classroom -- sometimes to once per year. And they need advanced notice to do that. So imagine running a factory where you've got these workers, some of them just making crap and the management is told, "Hey, you can only come down here once a year, but you need to let us know, because we might actually fool you, and try and do a good job in that one brief moment."

Even a teacher who wants to improve doesn't have the tools to do it. They don't have the test scores, and there's a whole thing of trying to block the data. For example, New York passed a law that said that the teacher improvement data could not be made available and used in the tenure decision for the teachers. And so that's sort of working in the opposite direction. But I'm optimistic about this, I think there are some clear things we can do.

First of all, there's a lot more testing going on, and that's given us the picture of where we are. And that allows us to understand who's doing it well, and call them out, and find out what those techniques are. Of course, digital video is cheap now. Putting a few cameras in the classroom and saying that things are being recorded on an ongoing basis is very practical in all public schools. And so every few weeks teachers could sit down and say, "OK, here's a little clip of something I thought I did well. Here's a little clip of something I think I did poorly. Advise me -- when this kid acted up, how should I have dealt with that?" And they could all sit and work together on those problems. You can take the very best teachers and kind of annotate it, have it so everyone sees who is the very best at teaching this stuff.

You can take those great courses and make them available so that a kid could go out and watch the physics course, learn from that. If you have a kid who's behind, you would know you could assign them that video to watch and review the concept. And in fact, these free courses could not only be available just on the Internet, but you could make it so that DVDs were always available, and so anybody who has access to a DVD player can have the very best teachers. And so by thinking of this as a personnel system, we can do it much better.

Now there's a book actually, about KIPP -- the place that this is going on -- that Jay Matthews, a news reporter, wrote -- called, "Work Hard, Be Nice." And I thought it was so fantastic. It gave you a sense of what a good teacher does. I'm going to send everyone here a free copy of this book. (Applause)

Now, we put a lot of money into education, and I really think that education is the most important thing to get right for the country to have as strong a future as it should have. In fact we have in the stimulus bill -- it's interesting -- the House version actually had money in it for these data systems, and it was taken out in the Senate because there are people who are threatened by these things.

But I -- I'm optimistic. I think people are beginning to recognize how important this is, and it really can make a difference for millions of lives, if we get it right. I only had time to frame those two problems. There's a lot more problems like that -- AIDS, pneumonia -- I can just see you're getting excited, just at the very name of these things. And the skill sets required to tackle these things are very broad. You know, the system doesn't naturally make it happen. Governments don't naturally pick these things in the right way. The private sector doesn't naturally put its resources into these things.

So it's going to take brilliant people like you to study these things, get other people involved -- and you're helping to come up with solutions. And with that, I think there's some great things that will come out of it.

Thank you. (Applause)
