Re: The first thing you need to know?
One can think critically, but unless one understands the hows and whys, there are no criteria upon which to base such criticism.
When I teach marksmanship initially, I make it a matter of monkey see, monkey do. Once they get the rote part down, we cover the same material a second time, with the hows and whys added.
...And more times, with increasingly subtle subject matter in the forefront...
IMHO, unless the learner has some satisfaction to count on, they will not retain the attention span necessary to stick around for the hows and whys.
One may learn to shoot in a basic manner, but one cannot advance without critical thought; and that critical thought, while crucial, comes later for my learners.
Right now, my Granddaughter is my active learner. She knows just ebough to be safe on the line, establish and maintain a sight picture, breathe and squeeze properly. I do not yet trust her to shoot without vigilant coaching. Beyond that, nothing; but she has shot in her first competition, and was at least competitive.
She's not ready to think the subject out critically, but she's beginning to ask the questions. This indicates to me that the ground is fertile for the hows and whys; and upon that, to build the critical thought faculty.
It's my considered opinion that such instruction follows a logical series of steps, and that this particular series is more efficient and effective; because it is based on the self perceived needs of the learner, rather than those of the instructor.
I learned my instruction techniques in Wood Badge Adult Scouting Education, which borrows heavily from the Marxist 'Manager of Learning Experiences' technique, and is learner-based and learner-paced.
I later became a Scouting Adult Leadership Instructor, District Adult Leadership Training Chairman, and Council Commissioner for Adult Training myself.
Marx had some good ideas and some bad ideas, and Scouting is not afraid to pay credit where it's due.
