Ask HN: What feature do you want to see in online education?
Hi HN! I'm a long time user, but due to privacy/anonymity, needed to create this throwaway account. I'm currently working in online education and have some time to work on a fresh new project (think ~100 hours over two or three months).
I wanted to know what kind of features HN users would like to see in the education space. I'm interested in all kinds of ideas and may pick one off to try and build it. For instance, one I've heard of before is an iPad companion app to online classes where you can create/record lessons with audio and a whiteboard (a la showme.com). Something that's already been done, but captures the essence of what I'm looking for is a good circuit simulator, or online code tutors like code academy.
Any/all ideas welcome. Thanks!

[ 3.1 ms ] story [ 24.1 ms ] threadI'd imagine an interaction like "why does f(x-a) shift f(x) to the right and not left?", where teachers and students could explain the answer with a graph that showed certain values as you slide a knob to adjust 'a'. Using some cleverly defined/usable toolkit. It sounds really tough to pull off, but I'm optimistic!
The list of things I could throw out as features we want to see in online systems, or standalone products that could make a big difference, is long indeed. That list, however, is highly dependent on which class of system you are talking about. Without giving yourself away, could you tell us if you are part of the rebel alliance (khan, udacity, udemy, mitx, etc...) or the dark side (blackboard, d2l, moodle, etc...)?
I won't give away our most interesting upcoming features, but I'm happy to share some things I think all systems should have and few if any do.
If I were in the position to really move the Khan system forward, I would focus on a few key areas. First, the teacher tools at Khan are fantastic for showing the flow of students through the material and tying in to standards based grading. But, and this is a big but, the tools for independent students are almost non-existent.
Our system is also self paced and one of the largest problems we had to solve was how to keep a self-paced system from being "I'll get to it one of these days". The Khan system, when it is outside of classroom pacing, definitely suffers from that problem. Our approach is to have the student set section or exercise deadlines for themselves, then evaluate them based on how accurately they meet those goals. It allows for flexibility in pacing but still taps into the motivation of a looming deadline. You can do this at the micro level (I will complete this exercise in 7 minutes), badge level, or group larger sections together for larger targets. Risk of just setting far future deadlines is mitigated by including data from other students to introduce competition. In addition to helping to motivate the student from a pacing perspective, it helps teach accurate estimation and integrity.
Second, and the only reason I am sharing this is because when we launch in a few days everyone will see it, is the concept of contextual notes. In our system, taking a note is not just creating a list. We tie that note to exactly what the instructor is saying and what was on the "board" when they were saying it, making the note system a way of building a reference library for each student. While you don't have to take the exact same approach we did, (as long as youtube is the delivery mechanism you wouldn't be able to anyway) you do have valuable data that you are not using to its full advantage - time coded transcripts.
Finally, if this is indeed Ben or Tom, please either fix the knowledge map or ditch it entirely. It's not helping your image to have half working features floating around.
Anyway, back to work.

* The choice between video OR text for lectures
* a place for people to share their notes, mindmaps
And finally, one of the things I miss most in something like Khan academy: A Syllabus. A tree showing where branches of knowledge begin and where they end.
I know Khan academy try this via the knowledge tree (or whatever it is called) but I find that to be a big mess. They do many great things, but that thing isn't one of them.
