Reading the blog post that this one links to made me immediately think of SRS - isn't that exactly what it's design for? Don't focus on the stuff you just learned, but on the stuff you are about to forget. Maybe we should be doing many-year SRS for our students and doing more cumulative testing and practice. Or maybe I'm still naive and blaming the teachers! I guess I'm just not a cynic.
Agreed. Last I checked (don't have a reference right now, unfortunately), Khan Academy was experimenting with a SRS-like feature in their system, in order to tackle this very problem. Everyone tends to forget stuff they're not motivated to use - it's not at all limited to "problem" students.
IIRC, I was told in
#lesswrongby a KA contractor or employee that they knew of SRS and some were thinking about how to integrate it.Awesome! This makes me more interested in KA as an organization.
Well, I'd be more impressed if they had already integrated it. They (some members) have known of it for probably years at this point, know it's a big win in review efficiency, and have a review process already coded and running. All the SRS algorithm is really just a sort of exponential for scheduling the next review! It's not any actual new functionality; my programming intuition is that it should be pretty easy to add, so that they still haven't rather annoys me. Lost opportunities...
