A chalkboard is an effective, inexpensive, and easily used visual aid. For field presentations where there may not be a chalkboard available, a portable board can be constructed quite simply.
To make a chalkboard:
1) Carefully sand one side of a piece of plywood.
2) Paint with blackboard paint or any other flat colored paint.
3) Before writing on a new chalkboard, prepare the surface by wiping the board with a cloth or eraser covered with chalk dust. This will make subsequent erasing easier.
To make a combination chalkboard/flannelboard, glue a piece of felt or flannel to the back of the board. Or make the chalkboard from a piece of masonite (lawanit). The smooth side can serve as the chalkboard without any additional sanding. The rough side of the board will support felt-backed pictures.
To use a chalkboard:
1) Be sure that everyone in the audience can see the board.
2) Don't scribble on the board willy-nilly. Write clearly using minimum 1" letters.
3) Keep your presentation neat and orderly; write from top to bottom.
4) Accent important points by underlining.
5) When explaining/discussing chalkboard material, stand to the side of the board and use a pointer.
6) Do not mix up your material. Clean the chalkboard with a cloth or eraser after each topic discussion.
7) Encourage volunteers from the audience to use the chalk board to explain their ideas.
NOTE: If you think you will need to use the material on the chalkboard at a later time or for another group, it would probably be better to use a marking pen and a piece of paper taped to the wall. You can save the paper and avoid having to write the material out each time.
