Searching for informations by themselves maybe ?
There is also a difference between searching within a textbook, where the teacher knows what the student will find, and searching the internet, where well… we have been complaining about the enshitification enough.
Also I support not letting the kids run free on the internet before they have aquired a bit of media litteracy.
Now that I think about it, a search engine for school could be a cool thing. Tricky but cool.
