What's the deal with Chessable?

I know that Chessable is a web site where people can create chess tutorials and courses. I've looked into it for five minutes (the maximum limit for thorough Internet research) and I couldn't see anything special that couldn't have been duplicated in Lichess studies.

Does any of you use Chessable and can you tell me if it has any extra features that are relevant and impossible to find in Lichess with LiChess Tools installed?

Its main draw is the spaced repetition system for learning openings

So if you could somehow mark studies, maybe even individual chapters, as part of a "spaced repetition bundle" and you would get recommendations on repeating the study there, that would be a nice feature?

on chessable it is not clear if there is theory of learning about the specific scheduling as a function of the student progress.

My impression, from more than five minute exposure (actually one or 2 opening courses, when I thought it made sense to try chess from that end of the complexity), is that it was the speficif course author chunking decisions based on the material.

But with lichess studies mechanisms within chapters for student progress tracking (the interactive lessons for e.g.), there might be ways to eventually (might need research, why I guess I am babbling here) tie in some of that scheduling with diversity of pacings for many student audience targets, multiplying possible efficacy of one author proposal, not relying only on author ability to conceive each student various abiltiies or time chunk or ambitions.

It is rather clear that spaced repetition or more likely re-exposure and smooth progression from the long term memory point of view is beneficial. I thought that chessable would be containing such notions already, but it follows what theories of chess learning are out there. And having automatic adaptability might be research still.

yet.. a direction that would allow some autonomous learning with some direction or guidline by teacher/choach/tutor/author.

nice feature.. Although I have no clue how to make that. I hope you find a clever way as for many other learning enabling features of LT.

Thoughtful chunking being spaced is already something. I just like to give my 2-cents on anything that moves.

The way I see it, and I apologize for not being more knowledgeable in the ways of spaced repetition is that you have a series of items you want to master. So in order to accomplish that, you first go through all of them in order, with some measure of success/failure. Then, based on that measure, you get to go through the same material several times.

If the testing of the material is successful, the time until you will encounter that material will become longer, while if the testing is unsuccessful, the time will remain the same or even become lower. The algorithm being:

• if success -> time doubles
• if failure after success -> time remains the same
• if failure after failure -> time halves

As I envision the feature, you first mark the material you want to repeat. For interactive lessons you may get an automatic success measure, for other chapters you might ask the user if they are satisfied. There would be a place to remove material from the spaced repetition system.

what the heck is chessable????

I suggest making a visit. Fremium model. But there are enough free ones to get an idea.

I think it is not that chess -content-fine-grain-aware on chesable. It seemed more about getting back to it, at the point your stopped.

But it is possible my experience was limited. There maybe be some layers.

But the idea of spaced repetition, in general (not in chess), is more about spaced re-exposure to a topic.
At large time scale.. Like you cram for an exam... a week or month later poof a lot is gone... you have studiied all during the semester, and crammed less the night before, and a month later well still around.. better internalized.

but in both cases, if going back to the material, consolidation of internalization or long term memory happens.. and then even longer spacing.. few months.. a year..

I do not know how fine grain that learning theory (what I described is empirical though) can be or has been made, and what of it with chess theories of learning.

I think what you describe, implies a good theory of learning hand in hand with chess model already shared.

I think that you may want to start with outer layer view (just some timing about chapter level progressoin), on the automatic side, that way, as your research into spaced repetition in chess happens you have a more general set up already.

Anyone has a deeper experience of chessable, beyond the session level scheduling. How things are separated, perhaps to be compatible with the automatic model above? Sure within the re-exposure to keep on progression, if the author made some theory of learning effort in chunking, then there can be quizzes along side the progression scheduling, or suggestions to start again back upstream (for re-orienting into the re-exposure).

I guess I am avoiding the woodpecker repetition temptation that the word repetition in "space repetition".

This is not about move sequences necessarily. There are opening courses. And perhaps some of those are about long sequences move repetitions, so perhaps a woodpecker aspect to it.

But I think the learning theory of space re-exposure (repeat and or progress) is more general it can be about harder chess things like position based skills learning (and there are many possibly nested scales of that in chess).

“on chessable it is not clear if there is theory of learning about the specific scheduling”

The easier method is a periodic retest of variations and repeat them acording to its antiquity times number of failures.
