Chalk Boards•Framed with wood to keep from breaking, and marked on with shards of slate•Used in the 19th century to save paper •In the 1990s potential health risks posed by chalk dust prompted the replacement of many blackboards with whiteboards

Projectors • Projectors began to be

widely used in schools in the late 1950s and early 1960s.

• Teaching materials can be preprinted on transparencies, which can be written on and reused.

• Today projectors are slowly being replaced by computer projection systems, interactive whiteboards, etc. due to technology advancement in society.

Hardcopy vs. Electronic Copy • A study by Neşet Demirci

– There was not a statistical difference in what students preferred

– No difference in the scores that the students received on both kinds of assignments.

• Costs– Electronic devices are higher in cost than

paper and pencil, but not in the long run – This article points out the security, and ease of

access with electronic file storage. This information was found on this website:

• Palm Pilots – The Palm Pilot is lightweight, and has many

functions that can be used in the classroom– the average K-12 student will save two trees a

year by doing their homework on a Palm Pilot.
