For anyone wondering what VIPKid lessons look like, here is a sample demo of one from their Youtube channel.
The one thing, I saw that in their teacher training they aim for a 70/30 ratio of student to teacher speech and I haven't found any videos where that was the case. Though maybe it is only for more advanced students.
Overall a really nice platform though!
Absolutely don't knock this. I teach robotics and tech part time to middle schoolers and if there's one thing that has helped me connect more than any other its being a living cartoon. Exaggerate everything. You should be half-way to full clown when lecturing or you're simply not getting through.
To prep for lessons, I don't study circuits, I watch CN. I'm a 40yo man who quotes Rick and Morty and can name all of the Crystal Gems. But it works like crazy.
