Khan Academy: a severely underrated homeschooling tool

Khan Academy is arguably the world's most popular learning website. Originally hosting math videos, Khan Academy has now expanded to include videos on biology, chemistry, physics, health and medicine, cosmology and astronomy, art history, civics, government, finance, computer science, economics, history, test prep, and music.

The site makes it beautifully simple to begin the process of learning a new math topic or refresh yourself on various subjects you haven't touched for years. The built-in learning environment tracks your progress and you have the ability to add students and view their progress. You're able to track how much of each topic (geometry, trig, algebra) you (or your students) have mastered separately as well as view how much of the entire subject (math) they've successfully got under their belts.

Most of the videos are between 5 and 15 minutes, making them easily digestible. In addition, there are practice questions to help solidify learning. The site is gamified: points are earned for watching videos and for completing practice questions. You can earn badges and view charts of your points earned over time. If you take a look at the site's gamification, you'' easily be able to see how using Khan in your homeschool could possibly spark a little friendly competition among your students.

I have used Khan Academy since it's early days. In high school, (I was homeschooled) I watched Khan Academy videos when I was still foggy on a topic that my curriculum covered, but maybe didn't explain as clearly as Sal Khan, the founder and the teacher in many of the videos, tends to. In college, I used Khan Academy to cram for math exams. The cramming itself is not admirable, but Khan helped make it effective.

One of my personal favorite bits about the videos is that Mr. Khan loves to explain WHY something works the way it does (an unlikely-looking math equivalency, for example) instead of just insisting that we do it that way because "that's how it's done", something I've heard from too many teachers who can't be bothered to explain the concept further. Also, Khan explains everything as clearly as humanly possible without being dull, which is wonderfully uncommon in and of itself. Here's a video from Khan Academy about the birth of stars to illustrate my point:

Khan Academy is potentially a priceless homeschooling tool. The quality and quantity of resources here are difficult to match, even with a paid curriculum. I would recommend it as a supplement to any of the subjects available on the site. I'd argue that it cannot be standalone curriculum because sometimes the practice questions lack breadth. But it is undoubtedly a wonderful homeschooling resource: it is almost a free tutor who knows everything about almost) everything.
