Kačí,
Thank you for your kind and detailed comment. I tried to formulate all the principles in a brief and clear way, I am glad that you like it and consider it useful.
As you said, I realized the importance of question-and-answer exchange during our online lesson, so I wanted to highlight it somehow in my observation sheet.
I am pleased that my observation sheet inspired you and you took some points from it. For me, your observation sheet (Suggestopedia) was inspirational as well.
In terms of the advantages and disadvantages, I didn’t realize possible drawbacks of the questions before. I see your point and I will add it to my sheet, thank you :)
