Hi Tomek,
Thank you for sharing the video of your student’s robot and your observation of their skills gaps in other seemingly less advanced technologies. It begs the question, how much does one need to know? Do those gaps need to be filled in for each learner or are work teams built so that specialists or generalists collaborate to work?
I have been immersed in online language instruction for the past eight years, so if you are moving forward on a online language school, I will endeavour to be a resource. I usually have more questions than answers.
