Do you learn better by yourself or with a teacher

Do you learn better by yourself or with a teacher?
I understand that their is no one best way to learn, however, I
believe that learning is more effective and efficient when a
teacher is present.
One of my past professors always said that “you simply cannot learn
if you do not ask questions. ” I agree with my professor completely.
No matter what you`re trying to learn, it always helps to have an
expert on hand to answer questions when you get to a confusing
aspect. There is nothing more frustrating than studying for hour
upon hour only to become stumped. Having a teacher present can
alleviate this shortfall and make studying more efficient and
effective.
A teacher`s assistance in learning material can also attribute to
retaining learned material. I have noticed on numerous occasions
that I am able to recall information much easier if it was obtained
through my auditory sense. I can remember several test-taking
situations where I have been able to recall a professor`s lecture, as if
he/she were instructing me on how to complete the test.
In the end, I understand that there is no one best way to learn.
Personally, however, I believe that learning is more effective and
efficient in the presence of a teacher. Having a teacher present will
avoid the frustration caused by “sticking points” and will allow for
easier recollection of concepts learned.
