G.L.A.D. (Guided Language Acquisition Design) is a research-based approach to teaching English language learners. It focuses on comprehensible input using visuals and realia to make content accessible. It also aims to create a safe environment with natural language progression from simple to complex. Key strategies include input, guided oral practice, reading and writing. The conclusion states that G.L.A.D. makes a significant difference in student achievement by teaching language through academic content in ways that develop higher-order thinking and engage multiple intelligences.
