Module 3: Rhymes of History

The technology I chose to discuss this week is the LCD projector. I have been teaching only 8 years and have seen significant changes in technology used in the classroom. I chose the LCD projector. According to Marples the first vision of a projector was in 1420 (2008). In 1971 when I was in 8th grade I remember that we would help the teacher thread the projector and if it broke we knew how to fix it and get it going again. We have come far since then. I also remember having a slide projector and hanging a white sheet on the wall to view the slide projection. The progression of projection has changed rapidly. The LCD projector and document camera are rapidly replacing the overhead projector. These changes have made presentations clearer not to mention what it has done to replace the microscope.

Presentations in education, and business has improved greatly with the use of projection equipment. LCD projector has rekindled the slide projector, film projector and opaque projector. Marples indicated that the first projection in 1420 was an image displayed on the wall with the use of a flame. The projection technology has greatly improved from those days.
