Final answer:
Using context clues is the most effective method for teaching multiple meaning words, as it facilitates semantic encoding and helps students understand and remember the various contexts in which a word can be used.
Step-by-step explanation:
The most appropriate activity for teaching multiple meaning words is using context clues. This method engages students in understanding words based on the surrounding text, making it a highly effective form of semantic encoding. Activities such as writing sentences that incorporate the target words within a context, and categorizing meanings based on their use in different contexts are practical examples. Though drawing pictures can support visual learners and memorizing definitions has its place, these methods do not actively engage students with the multitude of contexts in which a word can be used. Semantic encoding, where the meaning of the word is the focus, has been shown to aid significantly in recall, according to psychological studies.
