Conducting a raise points that you think should best be treated fully on another Demonstration occasion, then tell them so and explain your reasoning. Demonstration DEMONSTRATING If you yourself have ever gone to an office and been shown how to fill in a form, gone home with a blank one and then found you couldn't remember what you had been told-then you can have some sympathy for farmers who seem to forget so quickly what you tell or show them. Sometimes a very quick or slick demonstration by a skilled performer can be self-defeating. The action occurs so quickly that the processes are not absorbed by the watchers. And there is a danger that the very slickness of the demonstration can be off-putting, can dent the confidence of the farmers that they themselves could ever do likewise. A demonstration is an act of teaching. So what you do should conform to the principles outlined in Chapter Four concerning efficiency of learning. Perhaps it would be particularly useful at this point to remind ourselves of the six crucial conditions for learning outlined in that chapter: that the farmers should be motivated to learn; they should be open to admitting certain deficiencies in their current practices; they should be given a clear demonstration of what they are expected to learn; they should have opportunities to practise the new knowledge and skills; they should receive reinforcement that what they are doing is correct; they should have available the appropriate learning materials. This list is particularly relevant to those occasions when your main educational objective is to develop skills. So, without repeating the general points made earlier with regard to these conditions, let us review them specifically in relation to demonstrations. The first two conditions have been fully discussed earlier. They are concerned with the positive and negative feelings the farmers will bring with them into any learning situation. But your own ap- proach in conducting a demonstration will have its effect on them: if your performance is confident, your manner enthusiastic and Chapter 8
