What?
The
appropriate definition of the Demonstration Strategy is;
• Demonstration method is a visual approach to examining information, ideas and processes.
• It is a teaching method that allows students to see the teacher actively engaged as a learner and a model rather than merely telling them what they need to know.
In this method of teaching, the teacher performs the experiment before the class and simultaneously explains what s/he is doing. S/he also asks relevant questions to maintain the interest and attention of students. The students are compelled to observe carefully because they have to describe each and every step of the experiment accurately and draw conclusion. After thorough questioning and cross-questioning, the class draws conclusion.
Demonstrations to be done by the teacher have to be included as part of some activities. For example where resources are limited or the technique for the experiment is more difficult, ensure that some children take part in the demonstration. Make sure your equipment is well prepared. Ask for help from students and keep them involved by asking questions. When you do a demonstration make sure that all students can see what you are doing.

Why?
1. To stimulate interest in a particular topic:
Often the demonstration attracts student attention and generates interest by providing sensory stimulus that the written or spoken word cannot.
2. To illustrate points efficiently:
The demonstration is useful when time is limited or when an explanation alone is not sufficient. For example a well-planned demonstration of how to operate a microscope is far more effective than any amount of written or verbal instructions.
3. To provide a change of pace:
At times the demonstration method is used for the express purpose of giving students a break from other modes of instructions especially verbal ones. This change of pace avoids the boredom that tends to set in with prolonged use of one particular mode of instruction.
4. Lack of equipment:
All schools do not have enough equipment needed for the experiments for individual student. During such situations, a science teacher can resort to the method of demonstration to teach the concept.
5. Time constraint:
Due to vast syllabus coverage and the huge number of students in the class, sometimes practical experiments will not be feasible. At such time, teachers can demonstrate the experiments to make up for the time.
6. Risky experiments:
All teachers are aware that all experiments are not safe especially for small children. The risk is that there are possibilities of hurting students by glass splinters and burns or cause accidents in the class during the experiments. Hence, teachers need to perform the experiments by themselves.
How ?
1. Carefully plan the demonstration:
Like all other methods of teaching, the teacher must know exactly what s/he is doing. This is particularly true of the demonstration, where precision and clarity are crucial to the students’ ability to understand what they see. Careful thought and research are needed to make sure that all phases of the demonstration are accurately and logically presented.
2. Practice the demonstration:
Once a well thought out plan has been developed, ample time should be set aside to practice the demonstration. It is very risky to give a demonstration without having practiced it beforehand, especially when the procedure or topic is relatively complex or unfamiliar.
3. Develop an outline to guide the demonstration:
To ensure that the demonstration goes smoothly it is a good idea to have an outline that lists the steps to follow, the materials to use, the questions to ask and the important points to make. Developing such an outline provides the teacher not only a guide for carrying out the demonstration but also with a well designed framework into which spontaneous ideas can be incorporated as the situation demands.
4. Make
sure everyone can see the demonstration:
It seems obvious that the teacher would make sure that all students can see the demonstration. Unfortunately, teachers sometimes fail to do this causing a situation which results in student’s loss of interest and misbehavior.
5. Introduce the demonstration to focus attention:
Students are likely to be interested in the demonstration and to understand it if they have at least a general idea of what to look for as it proceeds. A few introductory comments emphasizing the essential features and key terms of the demonstration can serve this purpose as an outline or diagram on the chalkboard. It is however unproductive to use a worksheet as a means of orienting students because it tends to draw their attention away from the demonstration.
6. Ask and encourage questioning:
“Students should be encouraged to ask questions so that their verbal experiences are integrated with their visual ones” (Crawford, 1938). Also students should be asked questions at key points as a way of assessing how well they understand the demonstration.
7. Plan a follow up to the demonstration:
A demonstration should be followed by activities that help students interpret and further understand the important points that were presented. Such activities could include a discussion or a writing exercise in which students can describe what they have observed.

Advantage
1.Seeing before doing: Benefit from seeing before having to do.
2. Task guidance: Can be guided step by step.
3. Economy of supplies: Fewer supplies needed because not everyone needs to handle material.
4. Safety: Allows teacher to control potentially dangerous materials or machinery instead of students.
Disadvantage
1.Not hands-on: Not a direct hands on experience for student unless being lead step by step.
2.Limited view: Students may not have an equal view of demonstration, so some may miss an aspect of the demonstration.
3.Pacing issue: Not all students will be able to follow single paced demonstration
