In this urgent and timely professional development workshop, educators will explore research-backed strategies to elevate the reading comprehension skills of English Language Learners (ELLs). Understanding that vocabulary alone is insufficient for comprehension, this workshop highlights the crucial role of background knowledge—the "missing piece" of the comprehension puzzle. Participants will explore the interplay between background or "domain" knowledge and vocabulary development, learning how these elements work together to unlock deeper comprehension for ELLs. Practical techniques for integrating these insights into classroom instruction will be shared, ensuring that educators can immediately apply what they've learned. Through interactive and collaborative activities, participants will gain actionable tools to effectively inform instructional planning and be equipped with a repertoire of evidence-based practices to support ELLs and all students on their journey to becoming proficient readers and critical thinkers.
