Blog #11: Non-Computer-based technology

I think that one of the most important technologies developed for education is the overhead projector. It has been used for several years and is much easier to use than slides. The teacher can either used typed sheets or they can use a marker and write on the sheet which is very helpful as a visual aide in the classroom. I think that this is an important technology because tt projects images onto the screen, which enlarges them for children who have difficulty seeing what is written on the board.
Along with the overhead projector are the new projectors that do not require a transparent sheet, but you can use regular paper and it will display through a projection system. This means that a teacher does not even have to make a transparent copy, but can instead use a regular sheet of paper. However, it does have its downsides. It is not as easy to erase on a sheet of paper as it is a transparency. I do, however, think that this is an interesting invention and it will be a handy tool in the classroom.
