Here's the thing, and it's a little thing and an odd thing that I have noticed over the last few years.
Catalans have the worst time noticing italic writing. It seems to look just like other writing to them. They can only barely pick it out of a text and some have a great deal of difficulty doing so.
My thinking is this. When I was a child, the text books used italics to emphasise bits of text they wanted us to notice or remember, or it was used for the titles of books or magazines, etc.
Here, the text books use bold. They use it a LOT, no, a lot. Drives me bonkers, I have to confess, because I tend to end up reading the bold and not reading anything else. As do the students cause those are the bits that are on the test.
Seems they are inadvertently teaching the kids to scan...but scan possibly tooooo much. So much that they have a really rough time picking out italics.
Now I know though and I underline it in the text when I show it, and for those in real difficulty, I underline it throughout the exercise.
