There's an abundance of information on the Internet, but sometimes it's not very organized or accurate, and oftentimes it's very biased. One of the functions of Wikipedia is to help people make sense of information, especially in developed countries where there's an abundance of information. It's very important to have tools to filter the information you find on the Internet so that it makes sense, because information is not the same thing as knowledge. You need to be skilled at judging the quality of the information you receive and being able to integrate it into your wider knowledge.
You must be able to read and understand what you're reading. You must also have a wide vocabulary, as you're going to have to deal with a lot of different subjects. However, you also have to be skilled at recognizing fallacies. and be able to think logically. You must be able to evaluate and judge the information you find, because there's a lot of inaccurate information on the Internet. Another thing I should mention is that sometimes there may be quality information out there that's not compatible with your level of knowledge, so it doesn't do you any good. One of the mistakes people make is that now you can find very high quality academic articles on subjects like medicine, where you can read about a study that's been performed and the results of it. However, it's difficult to put it into context. If you don't understand the subject, you'll say: “Well, it's in Harvard Journal of Medicine, so it must be right."
I think collaboration is essential in education for several reasons. The first is that as we move forward in the world, work is based on knowledge and information, and collaboration is a very useful skill. If you don't have the ability to work with other people in a productive way, the process is going to be counterproductive. Collaboration is also a highly effective way to really learn something. If you're trying to learn something and you're working with other people who also want to learn about the same subject, you ask each other things, you challenge each other and get to know more about the subject. You also work together and try to resolve issues together in order to gain a much deeper understanding. A lot people who work in Wikipedia learn as much about the subject they're passionate about thanks to their interaction with other people as they did from their sources. They also digest information in new ways. It's a very powerful tool to help us understand things and bounce ideas off other people. If you lock yourself in an attic for five years and hypothesize, write and do other similar things, when you join the real world again to present your genius work, you'll probably discover that you've missed something really important and fundamental that you'd have noticed if you'd worked in collaboration with others. This doesn't mean that an individual person isn't important in terms of concentration, focus and understanding, as they are. However, you need to test your knowledge in as many different ways as possible by communicating with other smart people who are also trying to understand the world. It's a great technique.
