I think that people don’t check if translations or other additional resources are available. Maybe that should be more obviously in the lesson. Translations (or videos) are seldom (for less than 1% of the lessons) and therefore people don’t check if an translation is available because they made the experience that usually translations are not available.
I totally agree with Vera!
Maybe the video could be on the right frame, along with the audio. So you could scroll while reading the text. I like to watch the video and see where I am in the text so it’s easier to point out a word I don’t know. Specially with long texts.
I really like this idea; I didn’t even know that any additional resources like that were available. I guess I’ll have to start looking for them.
