MAXIMIZING THE USE OF THE OVERHEAD RPOJECTOR AND THE CHALKBOARD

LB#14

          I have learned that among instructional equipment, the chalk board is the most available.In fact, a school may have no computer, radio or TV but it will always have a chalk board.

          Most teacher today are not using chalk.They use marker maybe because it is easier and faster to erase.

Marker is suitable for white board which most classrooms are using today.But there are still classrooms utilizing green board which only good for chalk used.

           Aside from chalkboard, the overhead projector is another versatile equipment that is quite common today.By using this, the teacher can save time when presenting lecture on transparencies instead of writing these notes or drawing naively on the chalkboard. With photocopier, it is easy for the teacher to prepare notes on the transparencies.He or she just photocopy the hard copy using the transparency.Overhead projector is sometimes reliable than LCD.Using overhead projector is very advantageous because it is simple to operate.It is used in front of the classroom.Instructor can easily observe student reactions,control its attention and regulate the flow of information in the presentation.It is especially easy for teachers and students to create materials.The projected image behind the instruction can be as large as necessary for all in the students to see.Since the transparency, as it is placed on the projector,is seen by the instructor exactly as students see it.

           In using overhead projector, these are the reminders to observe by the teacher;

• Stand off to one side on the overhead projector wile facing the students.
• Don't talk to the screen.
• Avoid large tables of figures.
• Don't read the text on the slide.
• Avoid too much text.
• Presentation must be readable from afar.
• Place the OHP on the table low enough so it does not block you or the screen.
• Simple use of color can add effective emphasis.
