This seems to be a new language theory, where teachers use Comprehensible Input, speaking simply but using normal grammar, and describing things around them. See https://www.youtube.com/watch?v=8SjfhtikVoc&t=300s for some discussion of what this is.

Examples of French Comprehensible Input: https://www.youtube.com/watch?v=hlmA1vM6iKA and https://www.youtube.com/watch?v=T_tqEv3X3jc

It is of course a shame that there is nothing at all of this type in Irish, or at least not in any Irish you would want to learn. There are a couple of Youtube channels claiming to used Irish Comprehensible Input, but the accent is so bad you couldn't point anyone to them.

I'm just posting this to raise the topic of Comprehensible Input.
