What is the primary function of textbooks?

• A. They are primarily for decoration
• B. Textbooks serve as a source of knowledge, a teaching aid, and provide entertainment
• C. They have no role in teaching
• D. They replace teachers

Answer: (B)

Textbooks mainly serve as a structured source of knowledge and a teaching aid that also helps keep students engaged. They present topics in a clear, logical order, explain concepts with definitions and examples, and use diagrams or illustrations to make ideas easier to grasp. They aren’t just reading material—they’re designed to support instruction, with explanations, worked examples, and activities that teachers can pair with lessons. They function as a portable reference students can study from and as a consistent resource teachers can rely on to structure lessons, assign work, and assess understanding. While the content can be engaging to help maintain interest, the primary role is to support learning and instruction, not decoration, not replacing teachers, and not irrelevant to teaching.
