The document discusses the Sheltered Instruction Observation Protocol (SIOP) model for lesson planning and instruction. The SIOP model includes 8 components: 1) lesson preparation, 2) building background, 3) strategies, 4) comprehensible input, 5) interaction, 6) practice/application, 7) lesson delivery, and 8) review/assessment. Lesson preparation involves considering content and language objectives, meaningful activities, curriculum adaptations, supplemental materials, and ensuring concepts are appropriate for students' levels. Building background involves linking new concepts to students' prior knowledge and experiences and introducing key vocabulary.
