Now more than ever, we need alternatives to the traditional classroom  language teaching methods that don’t always work. Aside from [other strategies to learn a language from home, online courses are a great way to keep learning your language, wherever you are.  If you’re looking for an online language course but not sure where to start to decide which one, this article is for you. Here is a quick round-up of all the best and most popular language courses on the web at the moment, and a guide to which one is right for you.

Why take an online language course?

If you’re starting a new language from scratch, it can be pretty hard to pick it up without some guidance. Things like grammar and pronunciation are not easy to get right, so if you’re completely alone you’re bound to make some mistakes. Once you start making mistakes in a language, they are hard to reverse.

Free apps like Memrise are a great resource, but they tend to be more for practice than for learning a language from scratch. I can’t say I have ever seen a free app teach grammar effectively, for example. Nor do they usually help much with fluency. Sure, they will get you to a certain point, but to really learn a language, you’ll need a bit more.

Online language courses are proven to be far more effective than traditional classroom lessons. This is because you can find the course which best suits your needs and your learning style. You can work at your own pace, and you can focus on things that interest you, instead of sticking to a particular curriculum or stressing about exams.

So online language courses are an affordable yet highly effective way to learn a language.

The 8 best online language courses

You might have noticed that there really are so many online language courses. It can be overwhelming to have all these choices. Which one is the best and which one is going to teach you what you actually want to learn?

To help you make the decision about which programme you should use, I have put together a list of some of the best online language courses and how they compare. These all offer courses in multiple different languages, and they cover a range of budgets. The benefit of all of the online language courses mentioned is that they either offer money-back guarantees or free trial periods. So if you try and don’t like something, you can keep trying until you find the course that is right for you!
