What category do textbooks and written hand-outs fall under?

Textbooks and written handouts fall under the category of printed materials because they are physical documents that provide information in written form, which can be read and referenced by learners. Printed materials serve as a traditional and fundamental resource in education, facilitating the delivery of content and supporting the learning process through structured text, diagrams, and illustrations.

While audio/visual materials, guided learning aids, and interactive materials involve different formats and methods of delivery that engage learners in various ways, textbooks and written handouts specifically categorize as printed materials because of their focus on written content that can be easily disseminated and accessed by students for study and review. This distinction is important in educational contexts, as it influences how instructors design their teaching strategies and resources to accommodate different learning styles.
