Navigation refers to the user interface buttons, links, lists, and media player controls that allow students to operate an elearning course.
According to instructional design principles, course navigation should be intuitive, simple, and interactive for students.
Course navigation should be consistent, using the same terms, colors, and buttons (ex.-using exit vs. close, using the same icons on each page, etc.).
Also, navigation should utilize accessibility best practices to include students with special needs like color blindness or hearing difficulties.
