If you have a child that is a student at pretty much any level, then you need to check out Khan Academy. Even parents can learn a lot from this site, from basic math to trading stocks – there are over 3000 videos and tutorials to learn from.
I started a couple of weeks ago having my youngest son use Khan Academy to learn and review school subjects and even simply watch things on the site that interest him. I am sure teachers will have a different opinion about the site but I promise, this site only supplements what our teachers do, and in fact I think the content of the site should be part of the in-school curriculum or at least as assignments.
So why is Khan Academy so awesome you ask?
I have been watching my sons progress on the site and had an interesting observation when looking at one of the areas he studied on the site. The topic was number lines. You know, those lines that go from -10 to 0 then to +10:
Khan allows for “teachers” to track the progress of a student, look at their daily activity, and even guide them in their learning adventure. After my son did the section on “Number Line 3” I saw this interesting switch in his proficiency.
This graph shows each question in the evaluation, the score, and the time it took the student to answer the question. A couple of things, it looks like he got almost half of the questions wrong in the beginning. I saw he was having a problem with it and assisted, even showed him he can watch the video for the subject in the lower right. He now knows to watch the video when he is having a hard time. Once he understood numbers decrease to the left and increase to the right he aced the rest of the questions. The site even offers “hints” for each question. What I really liked about the questions were you had to read them carefully. Here is an example of one of the questions:
I am excited and look forward to watching my sons progress through the content of this site!
