What is the most effective strategy for building vocabulary knowledge?

Demonstrating how to use roots and affixes is a powerful strategy for building vocabulary knowledge because it equips students with the tools to understand and decode unfamiliar words. By breaking down words into their constituent parts, such as prefixes, suffixes, and root words, students can infer meanings even if they have never encountered the word before. This morphological awareness fosters a deeper understanding of language structure and can significantly enhance word retrieval and application.

This strategy not only expands students' vocabulary but also promotes self-reliance, as learners learn to approach new words with confidence based on their understanding of how words are constructed. As they encounter various words across different contexts, their ability to transfer this knowledge to other unfamiliar vocabulary grows. This method encourages critical thinking and enhances linguistic intuition, making it a sustainable approach for long-term vocabulary development.

Other strategies may offer some benefits, but they do not provide the same level of depth and understanding as teaching about roots and affixes. Using synonyms can help with contextual understanding, practicing with flashcards may aid in memorization, and reading a wide variety of texts exposes students to new vocabulary. However, without an understanding of word structure, students may struggle to fully grasp meanings or apply their vocabulary knowledge independently in new contexts.
