Correct Answer: all of the above.
the concept of word tiers is a framework used primarily in educational settings to help categorize vocabulary words according to their utility and frequency of use across different texts. this classification system, which includes tier 1, tier 2, and tier 3 words, assists educators in focusing vocabulary instruction to enhance student comprehension and literacy skills.
tier 1 words are basic vocabulary or everyday words that most children acquire in their daily communications. these words are typically familiar and straightforward, requiring little to no instruction for understanding. examples of tier 1 words include "dog," "happy," and "house."
tier 2 words, on the other hand, are high-utility words for mature language users. they are found across a variety of domains and are crucial for understanding academic texts. tier 2 words are often more complex than tier 1 words and provide a descriptive or nuanced way to understand concepts. they are pivotal in helping students read more complex texts and can significantly impact their academic success. examples include "accumulate," "concept," and "structure." these words are not just specific to a particular subject but are used across disciplines, offering significant utility and versatility.
tier 3 words are domain-specific terms that are more commonly found in specific areas of study. these words are usually encountered in texts related to subjects like science, mathematics, social studies, or literature. due to their specificity, tier 3 words are not as frequently used outside their particular field of study. examples include "photosynthesis," "amendment," or "parallelogram."
in the given question, the correct answer is "all of the above," which acknowledges that tier 2 words include those that appear in a variety of texts, can be taught to help students make connections to other words, and help hone general understandings of topics into specifics. each of these descriptions accurately reflects aspects of tier 2 words, emphasizing their role in building bridges between basic vocabulary and more specialized terms, thus enhancing both general and academic literacy.
