Question 81

The teacher's primary objective is to reinforce student learning of segmenting and blending phonemes in words.

The teacher introduces the prefix "kilo" to prepare students for encountering related vocabulary in science and math, which directly supports the reinforcement of phonemic awareness through segmenting and blending skills.

A) To reinforce student learning of segmenting and blending phonemes in words

This option is correct because introducing the prefix "kilo" aids students in understanding how words are constructed, thereby enhancing their ability to segment and blend phonemes. This foundational skill is essential for their literacy development, especially as they engage with more complex vocabulary.

B) To have students develop skill in manipulating syllables in easily decodable words

This option is incorrect as the focus of the lesson is not primarily on manipulating syllables in decodable words. While understanding syllables can be beneficial, the introduction of the prefix "kilo" is more aligned with phoneme awareness rather than syllable manipulation.

C) To allow students to practice isolating sound elements in phonetically irregular vocabulary

This option is incorrect because the vocabulary being introduced (e.g., "kilogram" and "kilometer") is not phonetically irregular. The lesson is centered around regular phonemic patterns rather than irregular elements, which does not support the objective stated.

D) To help students apply knowledge of onset and rime to recognize common chunks in words

This option is incorrect as the lesson focuses on prefixes rather than onsets and rimes. The teacher's goal is to enhance phoneme recognition and blending rather than to emphasize the application of onset and rime knowledge, which pertains to a different aspect of phonological awareness.

Conclusion

The primary objective of reinforcing student learning of segmenting and blending phonemes in words is effectively met through the introduction of the prefix "kilo." This focus enhances the students' phonemic awareness, which is crucial for their ability to decode and comprehend new vocabulary in academic contexts. The other options do not align with the teacher's stated goal, making them less relevant in this context.
