Plan what you are going to write on the board: keep writing to a minimum by using key words or conceptual diagrams; anddevelop topics by using the board from left to rightand top to bottom. APPL ICATIO N
Keep writing-A. neat:B. large, heavy and high enough to be visible by all;C. brief; andD. specific. APPL ICATIO N
Practice writing and/or printing in a straight line. APPL ICATIO N
Use yellow chalk on a green board, white on a black board, etc. APPL ICATIO N
If your chalk squeaks, simply break the piecein half. APPL ICATIO N
Learn to stand and/or move around so you do not block the view of learners as you use the board. N APPL ICATIOAvoidwriting and"talkinginto" theboard at thesame time.
Put the chalk down when you are through writing. This reduces the chances fordistraction caused by playing with the chalk. N APPL ICATIO
N APPL ICATIOUse the eraser to remove errors or makechanges. Using your hands only smears thechalk and may deposit oil on the board, whichcan serve as a dust collector.
In erasing the writings on the board, use a down-sweep erasing motion. Erasing theboard with a side-to-side motion only enables N APPL ICATIO the learners to observe (from a most unflattering angle) the instructor doing something resembling the "Twist." It also causes chalk- dust particles to fly into the air instead of into the collector tray..
When you are through with the material, erase itcompletely so that it will not serve as adistraction while the next topic is beingconsidered. N APPL ICATIO
N APPL ICATIOIntersperse writing on the board withquestions or verbal emphasis. Keep the classaware of what is being put on the board andwhy.
If important drawings or maps are neededon the board, a instructor is wise to savetime by: N APPL ICATIO•doing them before class, and•copying a projection on the board (from afilmstrip, slide, or opaque projector) ratherthan "free-handing" it.
Chalkboard etiquette: if someone will beusing the board after you, please dont leaveit for him/her to erase. Its nice to clean theeraser against the board as well. N APPL ICATIO
