A third-grade teacher plans a literacy lesson about a word-study strategy that helps students decode the vocabulary in the lists shown. The teacher's explicit instruction in which of the following techniques is best for supporting student growth in decoding vocabulary words that follow spelling patterns similar to those in the lists?

Morphemic analysis involves examining the smallest units of meaning within words, such as prefixes and suffixes. While this strategy is beneficial for advanced vocabulary understanding, it may not be as effective for third graders who are still mastering basic decoding skills and may find morphemes too complex for their current level.

Phonics rules teach students the relationships between letters and sounds, which is crucial for decoding. However, while phonics focuses on sound-letter correspondence, syllabication rules provide a more structured approach for students to tackle multi-syllable words, making it more suitable for the lesson's goal of decoding vocabulary.

Contextual analysis encourages students to derive meaning from the context in which a word appears. Although useful for comprehension, this technique does not directly support the decoding of vocabulary words based on spelling patterns, which is the focus of the teacher’s lesson.
