What is the primary function of printed materials in instructional aids?

The primary function of printed materials in instructional aids is to provide text-based information. Printed materials serve as a foundational resource for learners, delivering content and context that students can reference throughout the learning process. These materials often include textbooks, handouts, manuals, or worksheets that outline essential concepts, theories, and guidelines pertinent to the subject matter being taught.

By offering clear and organized text, printed materials help ensure that learners can access the information they need to understand the topic fully. They can refer back to these resources during discussions, activities, or assessments, reinforcing their comprehension and retention of the material.

While printed materials can contribute to entertainment, interaction, or simplification of ideas, their primary role remains the delivery of factual and educational content that equips learners with the knowledge necessary to succeed in their training.
