Becoming a good shooter in basketball--unless you are part of that very lucky, genetically gifted group of natural-born ballers--is a product of the combination of proper form and mental toughness. Skipping over foundational, basic basketball shooting skills can lead to the development of improper form, which can be difficult to "unlearn." Developing proper form, then perfecting it on the court (where mental toughness is tested), will make all the difference.
Stance
A basketball player's shot percentage should increase upon implementing the proper shooting stance. Stand with your feet about shoulder-length apart, your knees slightly bent (with a little spring to them) and your eyes fixed on the basket (the exact target is different for everyone: some prefer the front of the rim, some prefer the back, others a floating target just above the rim, still others some other spot). One foot should probably be slightly ahead of the other--this all depends on your own personal comfort and preference. Regardless of how staggered your feet are, they should be generally pointed towards the basket.
Grip
Properly gripping the ball can make a big difference when it comes to your shot. Grip the ball with the fingertips of your shooting hand, with the hand between you and the ball, while the other hand acts as a side support. The palm of your shooting hand should not be touching the ball.
Shot
Your eyes should remain fixed on the basketball hoop (whatever your exact target spot may be) even after you release the ball; in other words, don't let your eyes follow the arc of the ball. Bend your knees, then come back up, delivering a spring to your shot. Bring the ball up so that it is about level with your head, with your shooting hand directly underneath (still attached only by the fingertips), your shooting arm's elbow underneath the ball and your supporting hand on the side to steady it. With the bounce of your knees, release the ball by spinning your shooting hand fingertips forward, propelling the ball into a high arc.
Follow-through
Adhering to proper follow-through form can likewise increase your shooting percentage. Keeping your eyes locked on the basket, allow your shooting hand to remain up high--where it was at the time of release. The fingers of your shooting hand should be pointing directly at the basket. If your shot required a jump, you should land easily back on the court with knees bent again to provide cushion.
