This document discusses notice boards and flannel graphs as visual aids used in nursing education. It defines a notice board as a board used for posting information and lists its common uses such as displaying lesson plans and providing patient education. Principles for using notice boards include organizing content neatly and changing materials frequently. Flannel graphs consist of a board covered in flannel cloth and cut-out pieces with sandpaper backing. They can be used to demonstrate disease progression and medication mechanisms. Both visual aids engage students and supplement classroom teaching, though flannel graphs require more time and resources.
