Couple thoughts
According to stats, the stall spin is the number one issue, I don’t really get it, I think much is a CFI self licking ice cream cone, lots of CFIs are scared of spins, so it passes on to their students

Pre solo I used to do spin training with my guys if I could, at the very least I’d do extensive slow flight leading to falling leaf stalls, they had it laser engraved in their head to step on the high wing and break the AOA/unload the wing. I also had turn smart as mandatory viewing
I also was a fan of a continuous turning pattern, more of a oval than a box.
What does it mean to be PIC, if tower asks you to do something you don’t feel right about, “unable”, if you get all jumbled leave the area, get a new plan and come back, this is what we have fuel reserves for.
Comms are not potty training at gun point, just view it as a conversation but try to keep it brief, using “proper phraseology” is a distant 10th place, you’ll pick it up over time, just communicating is number 1, not just making announcements, but also asking and answering.
Hearing two planes on freq just make announcements, NO, hearing one plane about to take off, another say “turning base”, and both planes say “hey do I have time to take off” “sure Im on a 3mi base” etc that’s GOOD
Tech
If you can load a approach, I like to do even for VFR work, get the extended centerline and CDI, this makes it harder to line up for the wrong runway or a taxiway, minus that everything you need is outside, ADSB is great but the second you fully go eyes inside and trust it, Murphy can be a asshole
AOA
We have some really cool tech these days, one is having AOA in smaller planes, sadly most dont know how to use it.
A buddy of mine went through the whole official cirrus training thing, has a very nice SR22 and he’ll was flying that thing in like the space shuttle, mentioning air speeds, yeah airspeed needs to be referenced, but if you can fly your short final on AOA, AOA is primary and ASI is secondary, glance at it in a turn too if you’re concerned, ASI is like a honey badger, it don’t care about anything but how much flying that wing is doing.
Honestly I’d rather everyone have a AOA than ADSB, but we all know the S in ADSB didn’t stand for safety anyways.
I
f I was going to say one thing to make the pattern more safe, spin training and falling leaf stalls, have a good session of slow flight with turns to headings leading up to every falling leaf stall or spin for pre solo, make it clear we are in slow flight mode (should hear the horn the whole time if equipped) and then state entering a falling leaf stall/right spin/etc now, enter it on command but without being jerky, teach this before solo, and do it in every recurrent event.
When you get slow you a should be anticipating the wing drop and ready on the RUDDERS like
