Revision of Exercises to Improve Learning Retention & Effectiveness #2277

Closed mikewray closed 8 years ago

mikewray commented 10 years ago

Its well know that revising a topic a week after and then a month after dramatically increases learning retention and therefore overall effectiveness. I'm wondering if this is a basic way of capturing this functionality without the bells and whistles and going to the nth degree.

In its simplest form, perhaps an idea is that the icons on the knowledge map change to indicate e.g.

  1. On getting 10 in a row right put a green P over the gold star i.e. proficient
  2. 10 days later the greem P changes to a red R i.e. revision. When 2 in a row are completed correctly it goes to a green R
  3. 20 days laters the green R turns to a red M, when two in a row are done the full star is revealed

I know KA online does a whole lot of more sophisticated stuff with this but wondering if there is a simple way in capturing the essence of this i.e. student checks out his knowledge map every now and then. I think you would find it would have a dramatic increase in learning effectiveness which is our ultimate goal.

What your thoughts from a coding perspective?

I think this makes a lot of sense - we have something that is moving in this direction in the framework we are starting to introduce in the nalanda branch. Also, as we develop the student report screen further, this could be a good location for flagging this kind of opportunity to learn.

@wangguan59 if you have a chance to think about how we might present this to students, any input would be great!

This kinda reminds me of Ebbinghaus Forgetting Curve. I think it would be more effective with a topic review list when a students login to their account.

I worry there are too much various scheme of icon on the knowledge map, so one of my idea is to add red dot next to a filled circular icon. Just like FB the red notification that makes users to click and get rid it off.

Forgetting curve....how negative. How bout the Guan remembering curve. (:)). Anyway I got partway through Steven Jonas's talk from UCSD on Spaced Repetition but I guess I should go back and take a look.

The red dot is also a good idea, simple and just indicates something needs to be done (either revision or mastery). Whatever the solution it should be something simple but effective that captures the essence of what revision achieves in learning effectiveness. I think it's pretty easy with this one to go down the rabbit hole and create implications throughout the software by trying to make too sophisticated.

Hi there, just following up on this - any progress?

mikewray commented 10 years ago

Chasing up on this again - I'm persistant as you know :) I was thinking a simpler idea might be just to have a bouncing star means that it needs some revision. Trying to think of a very simple way to capture a very important learning concept. Learning retention sky rockets when a mastered topic is revisited twice, albeit briefly. It's how neural networks are made.

Hi there - just following up on this? I guess this one is low on the priority list but I do think if there is a simple way to capture this revision aspect would have a dramatic effect on learning effectiveness which of course is the ultimate aim of this.

Hi @mikewray - we do have two features currently in our Nalanda deployment that may help to contribute to this. One is a 'fixed block' of exercises that provides additional practice after mastery has been achieved. This could be tweaked to be something that gets recommended on the new student coach reports that are also in the same deployment (which you contributed so much to the discussion of the design). Also, in the same deployment we have a 'quiz' feature which can aggregate across multiple exercises for further review. We will be bringing these features into 0.13 (which we are aiming for early November - a bit optimistic perhaps, but that is our target). I will see what I can do when we bring those features in that will enhance this kind of review.

Thanks for your persistence!

mikewray commented 9 years ago

Hi there, just checking in. The above features sound good...how is 0.13.0 looking and what can I do to help?

rtibbles commented 9 years ago

With the introduction of content recommendation we can start to look at this in 0.15.

rtibbles commented 8 years ago

Not going to happen within the scope of KA Lite.
