When teaching vocabulary, what type of words should teachers focus on as part of their curriculum?

Focusing on Tier Two and Tier Three vocabulary is essential for building a richer and more nuanced understanding of language. Tier Two words are high-frequency words that appear across various contexts and subjects, making them valuable for students to know in order to enhance their reading comprehension and communication skills. These words often convey precise meanings and are used in more complex sentences, contributing significantly to overall literacy development.

Tier Three vocabulary consists of domain-specific terms that are used in particular fields or subjects. While these words may not be used as frequently outside of those specific contexts, they are crucial for students' comprehension of academic texts and participation in subject-specific discussions. Teaching vocabulary in this manner helps students not only expand their word knowledge but also enables them to make connections between different disciplines and deepen their understanding of the content being taught.

In contrast, focusing solely on basic Tier One words might leave students at a disadvantage, as they won't be challenged to expand their vocabulary and engage with more complex texts. Similarly, only teaching Tier Three words could lead to gaps in understanding common language used in multiple contexts. Lastly, while cultural references that engage students can be beneficial, they do not systematically build essential vocabulary skills necessary for academic success. Therefore, a balanced approach that includes both Tier Two and Tier Three words
