Descriptions
ELMO HP-A11QLC
OVERHEAD PROJECTOR .
The overhead projector facilitates an easy low-cost interactive environment for educators. Teaching materials can be
pre-printed on plastic sheets, upon which the educator can directly write using a non-permanent, washable color
marking pen. This saves time, since the transparency can be pre-printed and used repetitively, rather than having
materials written manually before each class.
The overhead is typically placed at a comfortable writing height for the educator and allows the educator to face the
class, facilitating better communication between the students and teacher. The enlarging features of the projector
allow the educator to write in a comfortable small script in a natural writing position rather than writing in an overly
large script on a blackboard and having to constantly hold his arm out in midair to write on the blackboard.
When the transparency sheet is full of written or drawn material, it can simply be replaced with a new, fresh sheet
with more pre-printed material, again saving class time vs a blackboard that would need to be erased and teaching
materials rewritten by the educator. Following the class period, the transparencies are easily restored to their original
unused state by washing off with soap and water.
