A graphic design teacher specializes in teaching students about specific techniques for creating art using graphic design. This can be a great career path for professionals who have a background in graphic design and want to share their knowledge with new professionals who might enter the field. Graphic Designers create visual concepts to communicate information. They create everything from posters and billboards to packaging, logos and marketing materials. Graphic Designers use elements such as shapes, colors, typography, images and more to convey ideas to an audience.
