Demonstration is showing how a thing is done and emphasizing of the salient merits, utility and efficiency of a concept, a method or a process or an attitude. A good demonstration is an audio-visual presentation.
Edgar Dale gives us three guiding principles to observe in using demonstration as a teaching-learning experience:
1. Establish rapport. Make yourself and your demonstration interesting to sustain your students' attention.
2. Avoid the COIK fallacy (Clear Only If Known). The teaching should assume that the students has zero or little knowledge about the topic being discussed. This means that every little detail should be discussed to make sure the lesson is understood.
3. Watch out for key points. Check out for points wherein an error would most likely be made. In that way the students would learn to watch out for these points to avoid error in the future.
Like everything else, demonstrations need planning. This include preparing the appropriate visuals to be used, setting our objectives, and rehearsing the demonstration itself.
In class, see to it that you get and sustain the interest of your students, keep it simple, focused and clear, do not hurry nor drag out the demonstration, check if your students understood the demonstration, conclude with a summary and hand out written materials at the conclusion.
A teaching should also see to it that he/she doesn't bind him/herself to a time limit wherein the objectives of the demonstration won't be achieved. It is better to learn a little a lot. Just like "Bahala'g ginagmay basta kanunay." Rushing defeats the purpose of the demonstration.
