What is the primary purpose of appendices in educational materials?

The primary purpose of appendices in educational materials is to provide supplementary information that supports the content presented in the main body of the text. Appendices often contain detailed data, additional resources, charts, or explanatory notes that enhance the reader's understanding of the subject without interrupting the flow of the main discussion. By housing this information in appendices, the educational material remains focused and coherent while still allowing readers to delve deeper into specific areas of interest or complexity. This structure aids in maintaining clarity and provides a resource for readers who may want to explore the material more thoroughly.
