Maybe I am wrong about this but I think a lot of recent research has shown that trial and error is a great way to learn almost everything. Even just making an educated guess, even if it is completely wrong, before learning something makes it much more likely that you remember and understand the thing that you learn. It’s a painful and time-consuming way to learn. But very effective.

Maybe Linux commands is a little different but I kinda doubt it. Errors and feedback are the way to learn, as long as you can endure the pain of getting to the correct result.

Needs qualification. Research shows trial and error learning is very durable, but it’s not the most time efficient (in fact it’s relatively poor, usually, on that front). The two concepts are a bit different. Yes, trial and error engages more of the brain and provides a degree of difficulty that can sometimes be helpful in making the concepts sticky, but well designed teaching coupled with meaningful and appropriately difficult retrieval and practice is better on most axes. When possible… good teaching often needs refinement. And you’d be surprised how many educators know very little about the neuroscience of learning!

I'm (pleasantly) surprised every time I see evidence of one of them knowing anything about it.

Trial and error is necessary and beneficial, but not after the student becomes frustrated or anxious/bewildered by the complexity. The research shows that striking a balance between teacher intervention and trial and error is the optimal approach. If a teacher notices that a student is way off course but they keep persisting in one branch of the trial-and-error search space, it’ll be best if they intervene and put the student on the right branch. The student can still use the knowledge of what wasn’t working to find the solution on the right branch, but just persisting would be ineffective.

Gaining true understanding/insight is necessarily trial and error. Teachers cannot teach insight. But they can present the optimal path to gain insight.

Trial and error was the root of what became my IT career. I became curious about what each executable did from DOS and with that did my first tweaking of autoexec.bat and config.sys to maximise memory. Years later I was the only one who could investigate network (and some other) problems in Windows via the command line while I was the junior of the team. Ended up being the driver of several new ways of working for the department and company.

Ditto. I found that people whose attitude was “let’s just try it” tended to be a lot more capable and effective. Nevertheless the prevailing wisdom when I was in IT was that if you had a problem that didn’t have an obvious solution, you had to purchase the solution.
