I've tried lots of different ways of feedback, and one of the most powerful ways I found is the feedback loop style shown above.
If I ask a bowler to bowl at a cone, they will consider it for a moment, then try to hit the cone. If they fail, they try again. More than likely after making a slight adjustment. The feedback is instant and easy to see.
I can see this working. Bowlers tend to get more accurate when bowling at a cone, with no other intervention.
The same is true for asking batsmen in nets to play the ball through a certain area.
I realise this is anecdotal, but research agrees. The controversial "10,000 hour rule" is a debated rule, but the research does show that instant, measurable feedback develops skill in most people.
Whatever your style of coaching, for me, communication is at it's best when you and the player can test-review-adjust and loop around again.
