Your up and coming student wanting to work on the next mission to the Moon is probably going to want to have a good background in mathematics.
Math was not fun for me. I kept asking WHY and not getting the answers I thought I needed. Just memorize what was needed to pass the test.
A Facebook entry by PJ, alerted me to the KHAN ACADEMY, a free way to learn math and other subjects on the Internet.
I thought I would check it out as I learned that taking Calculus 1, some 27 years before Calculus 2 is not the best way to learn mathematics.
By the time I was taking Calculus 3 I felt like I was just getting more behind and the college I was going to wouldn't let me take Calculus 1 over again because their computer didn't show any entry for their general math prerequisite tests. The fact that I had already had two later classes in Calculus from them didn't matter. Empty box on computer input for math test, no take Calculus 1. NEXT!
As a result I am definitely NOT a math whiz.
I viewed a number of the videos with Salmon Kahn explaining how he happened to start making YouTube videos to help his cousin learn math and finally giving up his day job to do this full time as a not-for-profit organization. When you check out the link to Khan' web site you will see a number of videos given at various venues explaining how he got started., Check out the TED Talk (and then the others also)
What started out as Sal making a few algebra videos for his cousins has grown to over 2,100 videos and 100 self-paced exercises and assessments covering everything from arithmetic to physics, finance, and history.
Browse our library of over 2,100 educational videos... Algebra
Topics covered from very basic algebra all the way through algebra II. This is the best algebra playlist to start at if you've never seen algebra before. Once you get your feet wet, you may want to try some of the videos in the "Algebra I Worked Examples" playlist.
If you want to do the exercises that go with the videos you need to sign up with a GOOGLE or FACEBOOK account.
That means you have to let the KAHNACADEMY have access to your account and then you will be presented with a web page that will present the problems you select or allow you to view the videos for a presentation by Simon Khan. You also will earn badges and points like a video game which gives you feedback and incentive to do better and faster as well as just practice for speed. The KAHNACADEMY is working with a Los Altos school here in Silicon Valley as a tool to help the students and teachers to best use their time.
The Khan Academy is an organization on a mission. We're a not-for-profit with the goal of changing education for the better by providing a free world-class education to anyone anywhere.
All of the site's resources are available to anyone. It doesn't matter if you are a student, teacher, home-schooler, principal, adult returning to the classroom after 20 years, or a friendly alien just trying to get a leg up in earthly biology. The Khan Academy's materials and resources are available to you completely free of charge
A world of exercises, with help along the way
Practice math at your own pace with our adaptive assessment exercises. You can start at 1+1 and work your way into calculus or jump right into whatever topic needs some brushing up. Each problem is randomly generated, so you never run out of practice material. If you need a hint, every single problem can be broken down, step-by-step, with one click. If you need more help, you can always watch a related video.
In the old days, I mean before the Internet, "education" meant formal education that you had to go somewhere to get, from a teacher whose interest and expertise in a subject and in teaching per se, might be limited. Education was restricted to those who lived in a country where it was either provided for free or affordable. Even if you did go to school, learning about a subject required that you have books on it. Those days are over. Today I'll share with you a website review that was a pleasure to do. Almost lost in the explosion of information about celebrities that you don't really care about, and the ability to argue politics ad nauseum with people all over the world, is a breathtaking fundamental change in access to basic education. Khanacademy.org is a site that is a perfect example of how the Internet makes high-quality self-education possible, for free. Among other things, it's a profound opportunity for individuals to empower themselves, and potentially change their lives.
Is the Khan Academy The Future of Education? (video)
by Aaron Saenz September 11th, 201
Will the school of the future need teachers? Probably. Will it need classrooms and textbooks? Hopefully not. To see what will replace them you only need to look to the ever expanding and educational Khan Academy. Originally developed as a means of helping his cousins with math, Salman Khan’s efforts have expanded into1800+ videos on YouTube, with nearly 22 million views between them. In these brief 10-15 minute tutorials, Khan explains basic (and not so basic) math concepts in a concise manner that students can easily digest and reference later. The academy also includes many videos on non-math topics like biology, history, and the economics of a cupcake factory. Khan Academy videos are viewed more than 70,000 times per day – that’s more students than most major universities. Check out an example of Khan’s work below, along with a review of the his academy from PBS’s News Hour. Efforts of extraordinary individuals like Khan could revolutionize the way we teach, replacing textbooks and typical lectures with free online tutorials that students can watch at their own pace.
