LB # 14 Maximizing the use of the overhead projector and the chalkboard

OVERHEAD PROJECTOR TECHNIQUES

• You can show pictures and diagrams, using a pointer on the transparency to direct attention to a detail. 
• You can use a felt pen or wax-based pencil to add details or to make points on the transparency during projection.
• You can control  the rate of presenting information by covering a transparency with a sheet of paper or cardboard and then exposing data as you are ready to discuss each point.
• You can superimpose additional transparency sheets as overlays on a base transparency so as to separate  processes and complex ideas into elements and present them in step-by-step order.
• You can show three-dimensional objects from the stage of the projector .
• You can move overlays back and forth across the base in order to rearrange elements of diagrams or problems.
