In my experience it is a good lesson for about 50% of absolute beginners, but a great lesson for 99% of folks who have just started grokking their "first" language etc.

I am now in the process of teaching an absolute beginner in my family and in this case I'll stick to my specialties because I can tell they'll become frustrated if they can't get _something_ working on their own. Thus, I bet they want clear "unstucking" help rather than a "let me google that with you". They are more concerned with the 1st thing, and not the broader "how does someone who know this stuff goes about learning?"

Anyway, I digress - in any case these initial lessons are great for me as a teacher to experience that discovery through them
