How to Use a Chalkboard When Teaching Something

As hi-tech a society as we are, we still use chalkboards in many in-class training and presentation situations.
What’s the most productive way to use a chalkboard? Here are the U.S. Department of Transportation guidelines for using a chalkboard efficiently:

1. Keep the chalkboard clean.
2. Erase all irrelevant material.
3. Keep chalk, erasers, cleaning cloths, rulers, and other aids readily available to avoid interruption of the presentation.
4. Organize and practice chalkboard presentation in advance.
5. Write or draw large enough for everyone in the group to see.
6. Do not overcrowd the chalkboard. :eave a margin around the material and sufficinet space between lines of copy.
7. Present material simply and briefly.
8. If necessary, use the ruler, compass, or other devices in making drawings.
9. Use colored chalk for emphasis.
10. Underline statements for emphasis.
11. Use a pointer when discussing chalkboard materials.
12. Stand to the side of the material being presented so that the entire class will have an unobstructed view.
