Read the school's mission statement and talk to faculty and administrators to see if your proposed class is a good fit at the school. Become familiar with classes in the department and note how your class would fit in to the overall curriculum. Study the syllabus for a similar class in the department.
Create a course description. Describe the goals for the class. Explain how students will benefit from the class and how they will learn the course content. Administrators may be more likely to approve a class that goes beyond lectures and discussion. Include new and engaging activities and assignments that will keep students interested.
Provide a list of materials needed, such as required books and technology. Using new technology in teaching the course is interesting and shows you are comfortable with it. Some schools may be hesitant to approve a class that would have significant costs, so be sure to indicate which materials are necessary and what less-expensive options there are.
Include a syllabus with a list of required student assignments with due dates for the duration of the course.
Write background information. Include your experience and education that qualifies you to teach this class. Include experience talking before a large audience, as this demonstrates comfort and experience with public speaking. In your background information, include preparation work done on developing the class content. If other academic professionals or people outside academia contributed, ask them for letters of endorsement for the project.
Compile all information in one, clean document. It may be several pages long. Have a few friends or colleagues read it and ask for honest opinions. Revise. Do not submit your first draft.
Anticipate questions from administrators when presenting your course proposal. Expect to be asked to explain how your course offers unique knowledge and how it will improve the department. Explain how it differs from existing course offerings. Be prepared to talk about how your course promotes the school's mission.
