I’ve corrected your essay. I’m afraid I’ve slightly changed it by adding new words. Of course, it’s just a diffident suggestion.
That's merely my suggestion:
Did you dare to think that distance education is something just from Brazil?
It is a world-wide phenomenon mainly in America.
There are many high school students, who don't attend classes in person anymore, but learn at home; and their opinion about online education is that it is really good.
They need to dedicate as much as in traditional ones, the same can be said about online college. It’s so popular nowadays for people to pursue education at an online university.
Most people don't have time to attend a face-to-face course at university, so studying by distance learning might be way too helpful.
Unfortunately, here in Brazil they take them for granted, of course, they won't never have the same value as traditional education.
Points to consider:
Did you dare think that " Distance Education " is something just from Brazil ?
You do need the infinitive “to” here. Did you dare to think…? Grammar rule.
I'm afraid it isn't just from here, and so super common in America. This sentence doesn’t make any sense at all. When we say “I’m afraid” it means Eu receio,i.e. I’m afraid to tell you: Eu receio em lhe falar/contar/dizer…. Or Eu tenho medo de lhe falar/contar/ dizer
I’m afraid of sth it also means: I’m afraid of cats. Eu tenho medo de gatos.
There are many high school students who don't study at presential schools anymore, but at home.
This word you made up. There is no “presential” in the English language.
We say face-to face course: curso presencial.
We say traditional school, online school .
Their opinion about Online School is that is really good and complexible
This world you also made up. There is no “complexible” in the English language.
If you mean the adjective “complex”, you may say: complex, demanding,
We say complexity but it’s a noun, e.g. the complexities of real life.
However, you can’t use complex in your sentence. Because if sth is complex, it means that it’s not easy, hence it would sound wrong.
. They need to dedicate as much as in traditional ones. The same can be said about online college,
It's so popular there and there are many people doing online college. This sentence doesn’t make sense.
(The- don’t use article here) Most people don't have time to attend a presential university, so studying by distance might be way too helpful.
Here in Brazil unfortunately (word order) they take for granted these graduations, of course it won't be never (wrong choice of verb.) the same as presential ones though.
