LB # 14 MAXIMIZING THE USE OF THE OVERHEAD PROJECTOR and THE CHALKBOARD

1. What techniques can help us maximize 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.                                        
   CHALKBOARD TECHNIQUES
  a. Sharpen your chalk to get good line quality.
  b. Stand with your elbow high. Move along as you write.
  c. Use dots as "aiming points". This keeps writing level.
  d. Make all writing or printing between 2 and 4 inches high for legibility.
  e. When using colored chalk , use soft chalk so that it can be erased easily.
