What are /r/Khan's favorite Products & Services?

From 3.5 billion Reddit comments

Unless it's being done with permission it appears to violate the stated copyright claims of Khan Academy: http://www.khanacademy.org/about/tos#11 - would qualify as selling materials from Khan Academy. Probably should notify them.

The best way to share programs for now is give them a link (the web page address) to your profile page (make sure you share your profile) e.g. my profile page is http://www.khanacademy.org/profile/cahawtho/

On there you should have Featured Programs (again make sure your profile is public). You can easily share programs there.

But if you have more than 4 programs, the best way to share the other programs is have one of your featured programs as program index. It would just be a simple title screen, and in the tips and comments sections you list the programs and web page addresses:

e.g. my index is here: http://www.khanacademy.org/cs/program-catalog/1042451882

There is rumours of them working on better ways to share programs, but for now this is as good as it gets.

Right now, Khan Academy is still adding a LOT of content, and translating is a very big job. If you're interested, you can go to this link and volunteer to translate things for KA, even if it's only a little bit. Every little thing makes a difference.

Yeah, here's the article: http://www.khanacademy.org/about/blog/post/63747872016/new-calculus-course-coming-fall-2014

If you go to your homepage (at plain old khanacademy.org), everything will make a lot more sense. We're trying to move away from people manually having to manage what they should do next using the knowledge map, and instead we're providing a recommendation model that suggests next exercises for people to work on.

If you practice exercises like normal, you can move them up to the practiced state, but you need to complete "mastery challenges" (there should be a button for it on the homepage once you've done a couple of practice tasks) in order to move up to the higher levels. Also, when you're completing mastery challenges, it will throw in review questions on exercises that you haven't worked on for a while, so you can do your reviewing that way.

Does all of that sound reasonable? Do you have any more questions? We realize it's a pretty radically new system, and we're still trying to work out some of the kinks (for example, we might want to add back the ability to see what exercises you should be reviewing), so feedback like this is great!

If you take a look at the one I spun-off of here you can see that I've added quite a bit to it and made an effort to make the code readable and well documented.
Do you think modifying someone else's code is bad? I credited them in my documentation and there is a link to their project on the page that my project is on.

I'm also doing all the Khan math exercises right now. I started with the top of the exercise map and just worked down and out, doing one node of exercises at a time. This is a good hierarchy of exercises, showing which ones lead to which other ones and so forth. I definitely recommend using it.

I don't know how the progress skills grid is layed out, but it only vaguely corresponds to that tree. Having done about 3/5 of the total exercises, my Skill Progress grid is solidly filled in on the top 1/3, dotted about in the middle 1/3, and empty in the bottom 1/3.

Sorry if this doesn't help but have you tried http://www.codecademy.com/#!/exercises/0 ? I found that I like their format better. I use Khan Academy for math but it progresses less linearly in Computer Science.

hi, just wondering which videos are missing from http://www.khanacademy.org/science/organic-chemistry/ that are on youtube? i see a couple at the bottom on the list, but i'm super sorry if things have gone missing on the site.

Yes, absolutely you can!

In fact, some of our most active learners use mostly our interactive math exercises.

All you have to do is login (http://www.khanacademy.org/login) and you'll be presented with all sorts of interactive content that'll help you learn — not just videos.

Enjoy!

Assuming I'm reading this right, this doesn't look like a logarithm question at all. Here is how I would solve it:

92x + 3 = 568 92x = 565 (subtract 3 from both sides) x = 6.14 (divide both sides by 92 and round to nearest hundredth)

If you are having difficulty with this type of problem, this is the video you want:

If you go here: https://www.khanacademy.org/cs there is a green button in the right hand corner that will let you start writing a new program, or you can browse through the ones other people have made and play with theirs. The one I made is here: link

He actually does have a good video on taking a square root manually, by dividing the numbers squared.

http://www.khanacademy.org/math/algebra/exponents-radicals/v/simplifying-square-roots

I actually use this method now when I want to take the square root and don't have a calculator with me.

Hey, I forgot one I think you might find even more interesting.

There is a book from 1910 that is praised for the approach it takes to teaching calculus. It takes a very simplistic approach to concepts to make topics less daunting. I started reading it a while back but never got far into it (I did however learn from it even after had finished my courses).

I can't really explain the style. It's much more casual than a textbook. Read the first chapter and see for yourself (it's 2 pages).

The current progress of my Editor

Right-click opens a "context menu" where you can currently choose to add a point. There is still a lot of work to do on the code.

Yes it will. I was a rather terrible student at school and never really was into math but i have been enjoying (yes enjoying) re/learning concepts that i was supposed to know back in the day. KA has both videos and exercises when it comes to math. http://www.khanacademy.org/exercisedashboard just start at the top and work your way down. every exercise has a video section that comes with it. Be sure to make an account.

I haven't come across any dubbed videos but if you click on the options under the video they have a list of sub-titles for the video. Some videos have portuguese as an option. You can contribute to adding subtitles and dubbing videos following this link.

I tried it and loved it :) I created a Koch Snowflake Fractal (from the video at http://www.khanacademy.org/math/geometry/triangles/v/koch-snowflake-fractal). Check it out here: http://www.khanacademy.org/cs/koch-snowflake/968481066 :) Click on it to hange the recursion depth.

Khan's pretty smart, if you can master everything in the math and keep up with the refresher quizzes that could definitely get you up to a good point for starting post-secondary, just make sure to take notes to help with retention.

If you still feel you need more, I recommend using some books andor math lectures from opencourseware or youtube, there is definitely some great supplementary material out there, if you put a request post on this sub, you'll hopefully get some good suggestions, you can pirate books from libgen.is if you so need too.

Advancing excel skills is a great idea for any analytics course, it's probably a good idea to get up at least to basics from a programming language, although I'm not entirely sure what would be the best choice for your field, I'd think Python or R you can find some good free lessons with research.

I think you're doing great though in terms of preparing, and really the best way to get solid with anything is practice, there's a lot of good things all around, I recommend having some fun with the project Euler stuff, which will be great for practicing applying the math you learn alongside solidifying your excel and programming skills

> Where abouts does it tell you total time spent?

As far as I know it doesn't -- I had to add up the 28-or-so days using a calculator.

> That's impressive though.

It was just revision for me, seriously. Keep at it and you'll get there, I'm sure.

Yeah, I just now sort of figured out a similar way of doing that in my browser......I would have edited my post, but saw your response. I already had Processing, and after looking around I saw that Khan Academy.....might be based on.....this.

It kind of works....but I'm not quite sure where to go from here. I updated my copy of Processing, and installed the JavaScript mode, and now I can copy and paste the sketches and run them without error messages, but I can't seem to get them to work quite right.

What you've shown me only appears to work for maybe a standard browser distribution of JavaScript or something.....you would know more about this than I would.......KA appears to be running something else based on Processing.

>I do not know why you need JavaScript for KhanAcademy (I suppose it's something with writing exercises)

KA has computer programming section that uses JavaScript. The sketches are all laid out for you, I just want to learn how to run them with my own software.

For my device, it needs Identity (though not Contacts). The web page for apps lists them all (at the bottom): https://play.google.com/store/apps/details?id=org.khanacademy.android&hl=en_AU

I'll have to check exactly what "Identity" entails...

BTW even if I don't end up using it, thanks for the sggestion! It's a great idea, and I hadn't thought of it.

EDIT according to the top answer here, you can deny access - as you said. It sounds specific to accounts, and not the general permission revocation I was thinking of. How to test it, IDK.

You mean free VPNs aren't working? I used Astrill and it always worked for me.

Your other best option is to go to youku.com and search for the name of the video you want to watch. For example, search "khan academy calculus derivitaves" or whatever other topic. You can even look for the exact title of the lesson on the KA site and search for each one individually.

You could then go back to khanacademy.org, which itself isn't blocked, to do the exercises. The only thing you'd be missing is if a particular video isn't ripped to youku and if you care about getting points/badges for watching the videos, in which case you need a paid VPN.

In The Why Axis, the authors showed that there are situations where student’s performances can be boosted by monetary incentives and the results could be measured. I believe that the Khan Academy website is a good vehicle to implement mathematics training for people struggling in math. http://www.amazon.com/Why-Axis-Undiscovered-Economics-Everyday-ebook/dp/B00BVTSBVO/ref=sr_1_1?ie=UTF8&qid=1404121085&sr=8-1&keywords=why+axis
