I really think that this is amazing.The fact that we can help someone anywhere around the world is a great thing. Think about the many children who struggle with the homework that they have because they don't have any one at home who can help them to understand it. When this happens it makes the child hate school, hate the teacher for giving them the work, and not really want to try because they just don't get it.
The fact that all we have to do is log on to the Internet and type in whatever the homework is and i can find an example with an explanation. In the text there may be many examples but without having someone explain it to the children they are still going to struggle. Khan academy has the problem and as they work it out they explain each step as they do it for anyone to understand and if they don' they can go back unlike a classroom where the teacher keeps going, she might answer a question here and there but for the most part she will keep going.
Earlier I said this is a great concept in learning but we don't yet know if this is the best thing for our future because it hasn't been out for that long but for the most part is has done a lot of good with those who have tried it. I see that as long as our children are able to find something that can help the children figure things out is always a great thing. I know we might find people without the Internet these days but there are many places where they can go and use the Internet. I have watched several of the videos and found them to be very helpful. So i do recommend that people try it and as everything else that comes out, we will have few glitches but that is something we will have to deal with when it comes because this does more good than it does bad.
