This document discusses literacy work aligned to Common Core standards, depths of knowledge (DOK), and PARCC assessments. It explains that DOK looks at the complexity of thinking required, not just verbs used, and provides examples of different DOK levels using the same verb. DOK levels include recall and reproduction (level 1), skills and concepts (level 2), strategic thinking (level 3), and extended thinking (level 4). The document also discusses understanding Common Core standards through analyzing what they say, inferring their intent, and considering how they align with and differ from current instructional practices.
