Do you attend Khan Academy?

As you may recall from his TedTalk, “Let’s Use Video to Reinvent Education” Salman Khan started Khan Academy after he got the idea from frequently Skyping with his cousins and subsequently creating videos on YouTube to help them with their math homework. The video lessons caught on and now Khan Academy has its own website and app.

What is Khan Academy?
According to their website, “Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom.”

What subjects does Khan Academy offer?

  • Math
  • Science
  • Economics & finance
  • Arts & humanities
  • Computing
  • Test Prep (SAT, MCAT, GMAT, IIT JEE, NCLEX-RN, CAHSEE, AP* Art History

As you can see, the subjects are focused on STEM. The “arts & humanities” sections are mostly art and some history; there is no English or writing at all. This is disappointing to an English teacher like myself, but I hope those modules are in development (or will be soon).

Who is Khan Academy for?
Everyone! Students, teachers, parents, and anyone else who wants to learn. Need to refresh a concept for a meeting? Khan Academy! Need to relearn elementary math to help your kid with homework? Khan Academy! Want to brush up on your history so you can sound knowledgeable on a date? Khan Academy! Want to study coding? Khan Academy! (Are you getting the pattern here? Good!)

Do I have to pay for Khan Academy?
No, it’s free! Forever. It’s a promise on their homepage. “For free. For everyone. Forever.”

Do I need a username/password to use Khan Academy?
Nope! You can log in to track progress, save content, etc., but it is not essential to log in to watch a video.

Are the videos hard to follow?
Some of the more advanced math may be difficult if you’re skipping around; however, in a general sense, no the videos are easy to understand and follow. There are two ways to learn in the video: visual and audio. The speaker walks the person through the topic with a drawing and audio information. Additionally, there is a transcript to follow if you want to skim through and find something specific.

Can you embed videos into your own website?
Yes! Click on a video and beneath it you’ll see a “Share” button. There is an option for embed. Paste the code into your site/blog and the result will have a heading and look like this…….

Adding fractions with like denominators: With like denominators, you’re basically just adding numerators. That’s not too bad, right? Can the resulting fraction be simplified?
