The Learning Process relatively small amounts of grain for which an adapted traditional basket would be perfectly adequate. Third, your presentation should be coherently organized-in other words, your messages should be easily understood by the farmers, whether in term of the language you use or the logical way in which you make your points. If you use a technical term with which the farmers are not familiar, then you should go on to explain it in everyday language. Percentages, for instance, may not mean a great deal-but "two bags out of every ten" is the kind of concrete language that farmers will easily grasp. Also, if your presentation of information is not well prepared, then there is a risk that what you say will be rambling and confusing. Finally, the presentation should be made as lively as possible in order to arouse attention and interest. The more confident you are of your material, the more you are familiar with the community in which you are working, the greater your chance to talk fluently and enliven your delivery with humour that you know will be picked up and appreciated by your listeners. All these points will be taken up again and expanded in the chapters that follow, which are concerned with various methods of communicating extension messages-various ways of promoting learning about agricultural topics and techniques. Practice Most of what you are trying to get across is to do with techniques, so the learning will have happened, not when you have talked or demonstrated, but only when the farmers can actually carry out the recommended tasks themselves. So the opportunity for practice becomes one of the most crucial conditions for learning. This is the major theme of the next chapter, where we shall consider different models of extension communication. We shall also be exploring the relative advantages and disadvantages of two-way as opposed to one-way methods of communication. Sufficient to say at this point that, if we rely on only one-way methods-talking and showing-then there is a risk ofinformation over-load. There is also the possibility that, without guided prac- tice, little or nothing will be learnt. The use of the word "guided" here is significant; because it is possible for someone, without guidance or supervision, to go on practising the same mistake! Chapter 4
