Coaching and Training by Demonstration
Live Demonstrations are One of the Most Effective Methods of Teaching
One of the most common and effective methods of training and imparting knowledge to others is through demonstrating the actual task or tasks which you require them to learn and then supervising them carrying out the task in the same way.
Depending upon the nature of the task, this may be performed "live" with the instructor there ready to step in if the person is about to make a mistake which would lead to problems, or if it is possible it can take place on a practice or dummy piece of equipment, machinery or apparatus so that if a mistake or wrong step is made it will not cause any damage to existing operations.
Learning by Active Involvement Rather Than Reading Textbooks
People learn much more quickly and take in more of the information being imparted to them if they are involved in practical activities which reinforces the learning rather than simply sitting there being talked at by at trainer or instructor, or through sitting reading through a large textbook as their concentration soon begins to waver. It is for this reason that distance learning or online learning schemes can be a difficult method of achieving an accredited qualification either in coaching or in any other area of training.
Learning by Doing and Practicing Before the Real Thing
By actually doing the task rather than simply learning the theoretical side of how to do it, they are much more likely to absorb the knowledge required in order to perform it when the instructor is not there with them. If they are able to work on a practice piece of equipment the instructor can actually let them make a mistake whilst performing the task, which they should then remember not do to again when it comes to working on the real thing.
