There are three main accepted methods of learning: seeing, hearing and doing. Mix your coaching methods to help players who predominantly only respond to either one or two of these styles.

Show me

A visual learner observes everything. They will focus on your body language rather than what you are saying. To engage them, you need to use facial expressions, demonstrations and visual cues. Instead of explaining how to catch a ball, show them and emphasise the key factors.
They switch off if you talk for too long without showing anything for them to look at. They may also not understand what you mean unless they have seen the skill in action.

Tell me

An auditory learner hears what you say and is sensitive to how you say it. Your tone, volume and speed of speech all impact on how they take in information. They are easily distracted by noises as they are trying to hear every word and how you say them.
They will be players who stand at the front of the group and nod as you are talking. They will ask questions to clarify things. It may take them longer to put what they have heard into practice, and they will need to be reminded of the key factors until they have the skill mastered.

Let's just do it

A doer will have a short concentration span unless actively involved. Even demonstrations won't engage them unless they are the one demonstrating. They are likely to be at the back of the group when you are talking and will probably be distracting others. Keep them active.
Use these players for demonstrations and get them to put into words what they are doing. Encourage them to stand at the front of the group and, if necessary, give them a ball to play with while you are speaking.
