Education had this sad 15 year period where it thought “competences” are all you need.

Turns out that without the world knowledge to have a base of facts, it is not.

Basically: you can't teach people to think without giving them some facts and ideas to think with. It's like trying to teach woodworking without giving the students any wood.

“Theoretical tennis”

Competences were always supposed to be supported by demonstrable knowledge and skills and behavior.

So I don't think it's true that relevant knowledge was deprioritized. At least it wasn't supposed to be.
