I agree.. to a point.
That is why teaching institutions exist... if it were all a simple matter of "look this up" I would be out of a job.
I have taught (private tuition) for nigh on 15 years and I have been involved in Scouting for many more, in short I spend almost all day every day working with kids of all ages.
Much of the teaching in schools actually resists kids asking questions. With my classes, I "have a go" at them for NOT asking questions. I teach them not to take everything I say at face value, to question, to ask why. But in order to complete that important part of their education I need to explain why, I need to answer their question, or explain why their question doesn't make sense or doesn't have an answer.
It takes children many many years at school (and university) to learn the schools of research and even then it can be difficult to sort the wheat from the chaff without expert knowledge.
Now I have had my fair share of kids that ask why, why, why just to be annoying, but these are easily dealt with. I can bore them back by explaining why, why, why... until it gets to a certain point that is ably demonstrated by something my step daughter and fiance said the other day:
"oh no... quick... stop asking... else I am going to catch his science germs".
Parents who are poorly educated are simply unable to help their kids find answers.
I have had umpteen homeworks handed in that are mere printouts of a webpage. Fine.. nothing wrong with that, in fact I encourage it. But in class the first question I ask them is : "Do you understand this?". The second is: "Can you explain this to me?". If not, I still have a job to do. :)
