Hello! I'm fairly new and I'm trying to learn German.
I have a question about Duolingo effectiveness. Can I actually learn fluent German in this or do I just use this as practice while learning somewhere else? I have been using this for not too long and I question if I can really learn good German.
The nice thing about German as a language is that there are many resources available outside of Duolingo. I recommend going through Duolingo, gathering a pretty solid foundation, and then embarking on other learning opportunities. Readlang.com is a good one for reading practice. YouTube has some great German language cartoons (I've been listening to Futurama in German) There are also obviously songs, and qualified native speakers giving grammar lessons. I subscribe to a German language newspaper. I get it once a week on my tablet so that's pretty cool too. Anyway, yes, do Duolingo. It won't make you fluent. But it's probably the best place to start! Good luck!
Basically not, this app is really amazing and helpful, you can't learn eveything on here though, when you finish this app, you'll know the basic grammar and intermediate of it, maybe you'll be able to converse with someone, I recommend you read books, watch videos and movies in german once you get finished this app, I hope this helps and good luck with it.
As the others said you can learn the basics and some vocab, but you'll need to supplement elsewhere too. However that said, a part I really like about duo is the community aspect, people are quick to give you ideas on how to suppliment, places to get more practise and connect with others. I love getting ideas from others on how they practise offline too, or on other sites it's handy. Generally speaking even with language classes there's never really a method that'll give you 100% effectiveness by itself, you need to practise in everyday situations too.
Can you learn to dance solely from watching YouTube videos? Or get good at a sport by reading the rule book? Or play an instrument by going to lots of concerts? No. You actually have to DO IT, you have to get onto the dance floor, the playing field, twang those guitar strings till your fingers bleed. Same with a language - you can only get fluent by talking to people who also speak that language, and it's a process that usually takes years. Duolingo is but a starting point.
