As I see doubts can range from too localized ones to multiple benefit ones, but often localized problems are closed or put on hold... Localized problems are beneficial on long term...
I don't know why questions especially the homework questions that haven't being asked properly are simply declared as off topic and put on hold. Phrases are really important? This is what I can understand. Beginners are really facing problems to uphold their doubts.
My question wasn't over whether beginners could ask a good question or not.or whether they get many upvotes or not. I just told that beginners are not adapted to ask questions in the style.
For e.g. homework questions are asked in a fashion."Am I right " and not in the way " Can you please check it". (as I read from a link) Questions can't directly be copied and pasted from text books...
But what I personally think is that solving up some textual numerical (for science-based sites) or factual questions can clear most of our concepts and doubts related to it.
I am not telling that beginners cannot ask good questions and that they cannot elaborate it. They can. But I am just saying that many of us aren't able ask a scienfic or any other questions properly perphaps. And experts/teachers are just downvoting them and giving us a link and we are reading the ans ( related to our improper way of questioning) and we aren't able to locate where our mistake lies. Mistakes are common. But among several mistakes it really difficult to locate our mistakes.
As we all know some doubts can't really be just dotted down. So for some people (not just beginners) doubts are remaining unsolved and unclear though they putting considerable effort from their own to express it.
