Whether you’re trying to learn something new or are just looking for some help with homework, having access to learning aides is essential. Sometimes schools will have an online resource database, where you can find a lot of relevant materials, but often this material isn’t actually helpful.
If you’re having trouble with a subject, then online textbooks probably won’t be adequate learning aides, so other sources may be required. Unfortunately, these tend to come in the form of online education courses, which can cost a lot of money (although they do provide value added services), but this isn’t really the case for youtube, which has a number of experts teaching pupils through short but informative videos and demonstrations on some of the principals young people will encounter in school. The help that these videos can provide is more of a few small tips to help supplement another form of education, rather than something which can provide a complete education on a subject.
