The Rhyming Peg Mnemonic Device Applied to Learning the Mohs Scale of Hardness
NOTE: This is a large file, 55.7mb in size! This article describes the use of the rhyming peg mnemonic device to teach Moh's scale of hardness. The "pegs" consist of a set of words, each rhyming with a number from one to ten, to which the mineral names are linked. The mnemonic drawings are incorporated into a poem. This technique is effective because it is meaningful, helps students organize information, provides many associations, uses the creative thinking skill of visualization of images, and focuses student attention.
