Khan Academy has created a generic framework for building exercises. This framework, together with the exercises themselves, can be used completely independently of the Khan Academy application.

The framework exists in two components:

• An HTML markup for specifying exercises.
• A jQuery plugin for generating a usable, interactive, exercise from the HTML markup.

You need to serve the files from some sort of a server. You can't just open the files directly in a browser. For example:

cd khan-exercises
python -m SimpleHTTPServer # or python3 -m http.server

Now if you open your browser to http://localhost:8000 (or http://127.0.0.1:8000/) you should see the contents of the khan-exercises directory. Navigate to the exercises subfolder, and an HTML file under there to see an exercise.

The process for writing exercises is rather well documented. More information about this process can be found in the Khan Exercises wiki. Specifically:

• How to Get Involved
• How to Write Exercises
• How to Test Exercises

If you're passionate about creating these exercises and want to apply to be a full-time exercise developer at the Khan Academy, please do so.
