Sounds great but I was expecting more evidence. They talk about this shuffling method, which interleaves material as a way to provide spacing and reintroduce material. But it appears to just be their opinion that it will help improve retention. Also what is the deal with this "hypothetical interaction between ISI and RI"? Why not do enough experiments to actually plot it out? Anyone can graph out a hypothetical interaction.

Years ago there was a great extended comment here on HN about teaching a linear algebra course using, among other tactics, a similar spacing of the homework problems. He reported excellent results. I wish I remembered the username. Ben something?

He also later expanded it into a blog post: https://bentilly.blogspot.com/2009/09/teaching-linear-algebr...

I really appreciate HN. There aren't many public online forums were one could ask about a user comment made on a related post posted years ago and in less than 20 minutes get two different responses linking to the comment from 15 years earlier.

Perhaps it helps the topic was "increasing retention". :-)

This comment reminds me of a recurring nightmare I have about a math class I forgot to drop, never attended, and have to pass for to graduate. I’ve no idea if I pass it or not, since I always wake myself up by then.

This guy wouldn’t have helped me though, since I never attended the class.

I think it was Ben Tilly and I think his user name is btilly. I also remember that comment you're referring too.

I think Accelerated Expertise comes to the same conclusion and references the studies to back it up. It's a good book!

The "Make it Stick" book https://www.amazon.com/Make-Stick-Science-Successful-Learnin... cites many many studies in this arena if you're interested.
