Review the brochure on pp. 67–70 in Technical Writing. Think about how you would explain arthritis to a fourth-grade child, a twelfth-grade biology class, and a 45-year-old patient receiving an arthritis diagnosis. How would you differentiate your message for each group? What are your main considerations? What kind of print materials would be most appropriate for each age group? How would you modify the language, images, and design?
