What are they teaching now in fire arms classes.?

What is the current philosophy commonly being taught by weapons instructors, other police academies. NRA, conceal weapons classes, etc? I am an old fart and was taught point and shoot, both eyes open, cup and saucer and a modified weaver stance. BAck then it was new school. but is now old school?!? LOL i know the FBI still uses the shoot me in the vest posture.... Just looking for your opinions, practices and thought it would be intersting and got the idea for the question from one that asked how do you shoot with both eyes open?
