The "Teaching Academic Content and Literacy to English Learners in Elementary and Middle School" practice guide was developed by the What Works Clearinghouse™ (WWC) in conjunction with an expert panel to support teachers in providing language instruction. The practice guide provides teachers with guidelines and examples of ways to systematically and explicitly build students' English language proficiency and literacy by providing English learners more opportunities to speak, listen to, and write about academic topics ranging from literature to science to history in daily classroom instruction. The practice guide includes recommendations for teaching English learners in K-8. This summary introduces the recommendations and supporting evidence described in the full practice guide. The recommendations in this practice guide summary apply to any teacher or instructor who works with students who have varying levels of English proficiency.
