Thanks for your long post. It’s great to hear some stories from classroom language teaching, and how the ideas behind LingQ can be transferred to group teaching.
Your materials are super-detailed! That’s nice, but how long does this sort of preparation take? Do your students contribute to them at all? Also, which program did you use to prepare the text with the translations on the right? In the video I saw it was more interactive than just a PDF.
In Turkey we have similar problems with English language instruction: many years of teaching at school, a lot of tests, and very little language ability at the end of it.
