New shooter's seminars are a great idea. I've helped out with a bunch of them, although it's been quite a few years ago now
New shooters really have to concentrate on where their muzzle is pointed and how to move / reload / clear malfunctions with their fingers OFF the trigger.
They also need a little bit of tutoring so they don't break the 180, re-engage targets they have passed, or sweep their support hand while trying to manipulate a door or window.
Time permitting, I think there is nothing wrong with coaching a new shooter a little bit as they do a walk-through prior to shooting.
You can only learn from experience if you pay attention!
