Which component does NOT belong to the SIOP Model?

Within the SIOP (Sheltered Instruction Observation Protocol) Model, several components are designed to promote effective instruction for English language learners. The model includes elements such as lesson preparation, building background knowledge, and practice/application, all of which focus on delivering content in a way that supports language acquisition.

Lesson preparation involves structuring lessons that are aligned with content standards and tailored to the diverse needs of learners. Building background refers to connecting new concepts to students’ prior knowledge and experiences, which is essential for language comprehension. Practice/application encourages students to apply their learning in meaningful contexts, which helps reinforce both language and content knowledge.

The component that does not fit within the SIOP Model is extra credit assignments. While these may be used in some educational contexts to motivate students or enhance grades, they are not a structured component of the SIOP Model aimed at facilitating second language acquisition. The focus of SIOP is on instructional strategies that directly support learning in a comprehensible and engaging manner rather than on grading policies or incentives such as extra credit.
