Analogies are useful for learning because, once we disregard the surface similarities, the shared structures can be illuminating.
Providing two analogies rather than one improves learning (Schwartz, Tsang, and Blair 3). Basically it creates a Venn diagram of the shared ideas that can elucidate the idea/theory/practice we are attempting to focus on.
Confession:
When I first heard of this, I thought it was a simple and fascinating concept. Just give students random things and they could try and figure out how those things “were like” the topic.
I have done that for a single random item (a bunch of small toys) in an FYC course during the introduction of students, asking them to explain how the toy was like their chosen major. It worked really well and was interesting.
However, for focused learning, I probably can’t throw random physical objects around the room for them to work with/on.
Random Practice Example:
Looking at the table in front of me, how is a bowl like writing? You fill it up with something significant. It is not particularly useful empty. It is designed to hold and transport things (or ideas).
Looking at the table in front of me, how is a cheese stick like writing? It needs to be wrapped up. It needs a particular level of wrapping to be useful. The cheese/writing can go bad if the wrapping/words are less than optimal. You consume it in small bites. You can put it up and eat/read it later.
Looking at those two objects, the ideas/food are what are wrapped/carried in the package or bowl and if the bowl or package is inappropriate (by type or size or whatever), the food/ideas go bad or do not get properly delivered.
That means that how we present our ideas really matters. Certain key concepts (like a thesis, topic sentence, and transitions) help create the correct carrying case for our ideas.
Application:
Can the students make that big of a connection? Or could they make better connections?
What if we had two or three students working together? Synergy and collaboration could lead to the sum being greater than its parts.
