In math education, there are two (not necessarily dichotomous) camps: (a) people who advocate drill and kill (which is a form of rote learning) (b) people who advocate constructive learning
Now, I see benefits to both forms of learning, and in fact, there's quite a bit that is complementary between them, and I can see how the drill-and-kill method would help with other kinds of reflective or constructive learning.
I came across this app called Yousician, which helps with the drill-and-kill aspect of learning guitar, allowing users to focus on extended periods of deliberate practice. I have heard some reviewers belittle this app due to the fact that it doesn't really teach you the elements of music that have to do with forming some kind of creative output. It just helps you with the mechanics of playing guitar.
This got me wondering if it is possible to bifurcate guitar playing into the mechanical or procedural aspects, like fretting the right notes when sight-reading, playing scales and arpeggios well, etc., and the creative aspects like forming melody lines and licks, etc. Drawing a parallel to math education, I don't see how you can become proficient at higher levels of creative playing without nailing down the mechanical/procedural elements first.
So, an app like Yousician would be a great first step as long as it is followed up by regular guitar classes to bring the student up from the end of beginner level to advanced.
Am I right in my analysis?
