Charts

1. Flip Chart

Flip carries a series of ideas arranged sequentially. Individually charts are tagged (or) bound to some support. During teaching, these flips are turned one by one sequence.

Advantages

1. It can be used as blackboard (or) as previously prepared sheets.
2. It is suitable for telling consecutive story with a number of points which need to be emphasised in outline fashion.
3. Less expensive
4. If sheets are just flipped over and not turn off, material is available for reconsideration and review.

Disadvantages

1. Paper has a limited space.
2. The top of chart is concealed with one (or) more blank sheet until the person is ready to take the topic.
3. The sheets, should be rolled smoothly over the top to avoid crinkling which will become increasingly annoying as more and more sheets are turned over.
4. The person must be stand to one side while displaying and turning the chart.
5. A strip of white paper, which is attached by paper clips, covers each heading, and they are removed at the appropriate moment. This process creates a certain amount of suspense and added attention.
6. If it is necessary to refer special pages, mark them in some way such as folded corners, paper clips etc.
7. Drawings can be prepared. Invisibly in light yellow pencil.

2. Pull chart

9. Overlay Chart

This consists of a number of sheets which can be placed one over the other conveniently on individual sheet.

This type of presentation is dramatic and effective.
