I've followed the link that Saim gave to the other thread, and this guy didn't get a lot of love here. I think he makes some good points, although nothing really new or groundbreaking. After watching a video of his about Lingoda, I'm pretty sure that he's criticising language teaching in general. He infiltrated an online class and made remarks about the content.
https://www.youtube.com/watch?v=kBDLOv_EFWEIt's a grammar lesson (English phrasal verbs) with almost zero takeaway. It's obvious that the students hardly learned anything new, and didn't participate in a meaningful way. I'd even argue that they were just more confused and demotivated after the lesson.
The teacher himself demonstrates that everything could be learned from the internet in a much quicker and better way.
It's been a long time that I last went to a language class, so I found it quite interesting with the eyes of an experienced learner. It's obvious that you need to know what you're looking for and need to be assertive if you pay for something like this. Just booking something that sounds good and following it passively is not a good idea.
I also remembered an online class for DELE C2 I saw on youtube. It's very long, don't watch it.
https://www.youtube.com/watch?v=KmJaIesgCXMThey're doing exercises from the
Cronómetro book, and they are listening to the audio and read things together in the lesson. The oral task is fine, that might have advantages. This teacher is also googling everything, and clicking all the time. He's just complicating things with links and extra stuff instead of concentrating own how to solve the task. It's actually annoying. What a waste of time and money.
