Maybe compare and contrast online schooling to regular schooling, then lead into the idea that online schooling provides you with many more resources than just a teacher could, plus it allows for a different learning style. Then conclude with your main point and maybe one fact about it
I suppose as supporting ideas (reasons) you could put are that online college classes are convenient because you could virtually take them anywhere as long as you have a computer, they allow for those who don't do well in social environments to do well in school and if you have a busy schedule you could take online classes whenever you have time.
