At UC Berkeley, we offer student-led courses called DeCals. Students usually take these classes to add 1-2 units to their courseload. I designed the Introduction to Photoshop and Illustrator course material by reading books and using online resources. Students with little to no experience are taught basic design principles through the use of Photoshop and Illustrator. I designed the course material from beginning to end. Each week consists of a 45 minute lecture about a tool or design principle followed by an hour long tutorial for students to practice their new knowledge.
