This document defines and compares different types of printed educational materials like leaflets, pamphlets, and booklets. It discusses their purpose, components, design principles, uses, advantages, and disadvantages. Leaflets are single sheet handouts used to disseminate information to large audiences. Pamphlets are multi-page but unbound, often used to explain an issue or promote a cause. Booklets are small bound books providing more detailed information on a topic. All of these materials are low-cost ways to educate groups through written and visual content if designed and distributed effectively. However, they rely on literacy and may not engage all learners.
