Analogies, metaphors, and similes help learners to associate new concepts with their previous knowledge or experience. These figures of speech create pictures that connect the teacher and learner to the same idea. Gerry Spence, in How To Argue and Win Every Time, wrote, "Words that do not create images should be discarded." And he follows his advice. For example, Spence writes, "To get a prejudiced judge off a case is like prying a tooth out of a rabid gorilla." This allows his readers to visualize the concept. Can't you see the gorilla frothing?
Analogies can be used to make complex topics simpler to understand. Susan Boyd, author of Accelerate Computer Learning With Analogies, explains that "turning off the computer in the middle of an application is like kicking the ladder away while the painter is on the third floor." She uses analogies to get her audience's attention and to make seemingly dry or dull subjects more interesting.
This one is from Alan Cooper's The Inmates Are Running the Asylum - he compares programming before the design work is completed to a parachute maker telling the jumper, "By the time you are ready to hit the ground, I’ll have stitched together a parachute." He continues, explaining that there is "abundant waste with this method - like a carpenter cutting boards by eye until he gets one that fills the gap in the wall."
Here's another from Alan Cooper - "It’s a common mistake to copy the trappings of success, rather than the root cause of it. It’s like seeing General George Patton’s pearl-handled revolvers, and drawing the erroneous conclusion that to be a good strategist one must wear ornate side arms.
An analogy is used in Harper Lee's "To Kill a Mockingbird" when Scout explains to her father why he shouldn't report Boo Radley — "It's like killing a mockingbird, isn't it?"
Socrates said that learning is like giving birth, and teaching is like being a midwife.
Ralph Waldo Emerson believed that "science is nothing but the finding of an analogy."
If you wanted to explain how a small decision can have far-reaching consequence, you could suggest picturing a large and heavy gate - it moves very little at the hinges but a long way out at the circumference. A very small movement at the hinge brings a long movement at the end of the gate.
