Literally speaking, yes. You could learn basketball history, statistics, official rules, and maybe things like classifications of tactics or something via Anki, but not basketball itself.
More generically speaking, maybe. A few days ago I looked into the spacing effect on motor skills question : http://www.gwern.net/Spaced%20repetition#motor-skills I don't have fulltext for all the citations yet, but it looks like there's something there (even if it's not as strong as spacing effect on declarative memory or language).
You can play basketball well if you repeat a dozen core motor skills with high precision 10,000s of times.
It interesting to ask how you best spread out those 10,000 repetitions but I don't think that Anki helps with that goal.
There might be other motor skills were a high number of repetitions aren't central where SRS is more applicable.
If you want to spread out your practices, you're going to have to start somewhere. The Supermemo algorithms are as good a starting point as any unless you're willing to hit the stacks and compare the musty motor skill studies head to head.
Spreading out 20 times of practice is a whole different problem then spreading out 10,000. In addition it's not clear what counts as "correct" answering and forgetting something.
Not inherent to the effect; you can get the spacing or testing effects without providing the right answer or measuring the response.
I think it's very inherent to the supermemo algorithm. Otherwise how does learning without spacing looks like?
I think this got derailed because gwern is trying to distinguish between the spacing effect the testing effect, and Supermemo/Anki. See gwern's literature review for clarification. In a domain where what counts as 'testing' isn't clear, perhaps basketball, then you might just try to used spaced repetition, which is what gwern is suggesting I think.
Space and testing effects are different, but work well together, and Anki/Supermemo are software that try to take advantage of these effects.
If only there were hundreds of studies listed in http://www.gwern.net/Spaced%20repetition#literature-review which demonstrate that there are many ways of spacing learning which don't exploit feedback like the SM algorithms demand...
If someone takes a weekly class that's teaching dribbling every monday, then you could call that "spacing learning". I don't think it's valuable to put that way of learning in the same mental category as Anki and Supermemo.
One of your studies says:
If you are looking at driblling or throwing free throws, I don't see a clearly distinguished testing from restudying.
Why not, when they're very similar and may be exploiting the same underlying neurological effects (we don't really know the basis)?
Begging the question? There no possible way to learn a skill that requires 10,000s of repetitions without spreading the practice over time. Out of the many ways that people train basketball you don't gain additional information when you get to know that someone learns basketball by learning on multiple days.
If someone tell you that he's learning vocabulary via SRS with my more narrow definition that tells you a lot about the way he learn it.
Above studies suggest it is valuable.
Do judge whether that's true we need to find an agreement about what we mean with it.
