Oldskool, yeah, they are obsessed with "worship." JWs are particular with their labels! Family Worship replaces family study, but initially there was some confusion on that because I remember some brothers thinking it was in addition to family study.
There's not really any structure per say. It functions just like family study. Parents are free to choose whatever they want to go over, though it is suggested they use the different activities from the website.
In recent years there has been an increase in tailoring publications and new releases for young kids and teens. If you're wondering why the magazines and books are so simple, that's why! There's even a video series with two made up kids: Calab and Sofia along with whiteboard animations. So family worship is usually the time to use those materials to reach kids. Group or multi-family worships are also encouraged. Ive gone to a few myself and it's almost always geared towards the kids: Building an elaborate Ark, Bible Jeopardy, etc with dinner at the end.
The society never thought the org or world would be around this long and now their old advice to hold off on getting married, having kids and going to college is biting them in the ass. So now the focus is on indoctrinating as many born-ins as possible.
When I was growing up in the 90s, all we had was the My Book of Bible Stories. But now? There's a lot more books and pamphlets for kids. They even have one for toddlers with bright colorful pages and rhyming stories about Jehovah creating everything "for you and me!"
They are still pretty anti-college, but I've noticed the rank and file members have really stopped being as judgmental about it. About two years ago, Bethel was asking for brothers and sisters with tech skills to volunteer some of their time to assist with whatever. It was a VERY long list, many of which you'd have to have gone to college to learn or had dedicated a lot of self taught hours to master on your own instead of pioneering. I remember being quite angry because one of the fields I wanted to go to school for was listed.
Excuse me, I have to go vomit.
