What teacher action is most effective for fostering greater depth of preschoolers' comprehension of word meanings?

• A. Giving multiple definitions and examples of new words
• B. Providing a single definition
• C. Using only visuals
• D. Rehearsing definitions

Answer: (A)

Understanding a word deeply by preschool shows comes from hearing and using it in many different ways, not just memorizing one meaning. When a teacher provides multiple definitions and several examples, children see that a word can have different senses and functions. They encounter the word in varied contexts—talking about its temperature, describing a character’s behavior, or using it to express excitement—so they build a richer, more flexible mental map of what the word can mean. This kind of explicit, broad exposure helps children generalize the word beyond a single sentence and apply it in new situations.

Offering just one definition tends to give a narrow, static meaning. Young children learn best when they see how a word works in different sentences and contexts, which helps them infer meanings and connect the word to their own experiences. Using visuals alone supports recognition, but it often doesn’t convey how the word works in language and thought beyond what is pictured. Rehearsing definitions focuses on memorization rather than meaningful use, which doesn’t promote deep understanding or the ability to use the word flexibly in everyday talk.

So, giving multiple definitions and varied examples directly supports children in building robust, transferable word knowledge that they can draw on across contexts.
